Water Damage In Your Home/Office: Seven Scenarios
Water damage and homeowners policies can be a tricky issue. You really have to sit down and talk to your insurance agent and make sure you have coverage for basic issues. In my experience, insurance companies will not cover the cause of the problem but they will pay for any resulting damages. For example, if you had a malfunction of your water heater which flooded your home/office, they usually will not pay to for the actual repair of the damaged water heater. But they will cover any cost from the damage to the structure that the water caused.
This does not cover a freeze-up situation. If you the water damage was a result of the frozen pipe, if it was caused by unforeseen problem insurance covers repairs to both the frozen pipe and the resulting damages.
Again, please speak with your insurance agent if you have an issue. They are your friend. By talking to him it does not mean you are putting in a claim. Whereas if you call your insurance company and ask questions, they automatically log the call as a filed claim.
Here are common water-damage scenarios and possible coverages.
1: Its the middle of winter. You go away on vacation. The temperature drops to 5 below zero, causing your water pipes to freeze and burst. Your neighbor calls you why you are away to tell you that your house is a block of ice .
Are you covered?
Yes, you're covered for water damage from burst pipes, but most policies won't cover you if you've left the house unoccupied and without heat. If that's the case, your claim could be denied because you've failed to perform your "Due Diligence" that would have prevented that accident.
2: Your pool cracks and floods your lawn and into your basement.
Are you covered?
The damage to your basement and your personal property are covered, but not the damage to your lawn. But again, ask your insurance agent and check your policy. According to a sample policy, "We do not cover land, including land on which the dwelling is located." However, your lawn is covered if it's damaged by certain "named perils." These include fire, explosion, riot, aircraft, vehicles not owned by you and vandalism. The amount of coverage for lawns and plants is small — usually only up to $500. Swimming-pool leaks are not a named peril. But if your leak was caused by a tree falling on the pool, it would be covered.
3: Your washing machine overflows, flooding the basement.
Are you covered?
Yes. But it depends on your home insurer's view of the problem: Did you fail to maintain the washer properly or did sudden, accidental damage cause the flood?
"Most of the time, if an appliance breaks and water goes all over, insurance covers it. In the case of a washing machine, you might need to purchase replacement parts out of your own pocket because they were not maintained correctly, but the damage to your basement is covered," says Griffin.
4: A sewer backs up, flooding your basement.
Are you covered?
No. Standard home insurance policies don't cover sewer backups, and many specifically exclude damage from sewer back-ups. Special endorsements are available, at added cost, for sewers and drains. Call your insurance agent to find out if you have the endorsement. It is not a fun job to cleanup. Trust me.
5: Water seeps from the ground into your basement, damaging your foundation and interior.
Are you covered?
No. Seepage is considered a maintenance problem, not "sudden and accidental" damage, and is excluded from home insurance coverage. Rainwater falls into this category.
6: During a heavy rainstorm, water leaks through your roof. The roof is damaged, as is furniture.
Are you covered?
Somewhat. You're unlikely to be reimbursed for roof repairs because that's a house-maintenance issue. If if it turns out that wind has damaged the roof you might be covered. Call your insurance agent to find out if have an issue. But the water damage to your home is covered. Damage to your furniture is also likely covered if you have a standard H0-3 homeowners policy, but not if you have a generic HO-1 policy (which many insurers don't even sell anymore).
If your neighbor's tree falls on your roof, the damage to your roof, home and belongings is covered. Your policy also reimburses you up to a certain amount, usually around $500, for the cost of removing the tree.
7: A nearby lake or river overflows its banks, causing a flash flood in your living room.
Are you covered?
No. Flood damage is not covered by home insurance. You must purchase flood insurance for that. You can purchase flood insurance as long as your community participates in the National Flood Insurance Program. But flood insurance does not kick in for any property below the front door. Which mean if you get flooded and you walk into the damages area and have to step down to get to it, they do not cover anything below grade.
Tips
I touched on this earlier in this post. But I can't stress this enough. Don't shoot yourself in the foot by reporting damage to your home insurance company that's not covered by your policy. Your damage report may still go on your insurance record and look like a claim when you shop for new insurance in the future. Call your insurance agent. They are your friends. It will not cost you anything to ask them questions. And they will answer it honestly and openly because your are their client. their job is to serve you. Whereas the insurance company will be looking out for the insurance company.
Be careful how you report damage to your insurance company. While you should be truthful, make sure you explain the situation using the most accurate language — or you could find your claim denied.
"What you say initially can affect the outcome of your claim. Many people believe their house is flooded because it's full of water — but it's not a 'flood' by the insurance definition," says Allan Sabel of Sabel & Associates, a Bridgeport, Conn.-based adjusting firm.
This may seem like a minor distinction, but your insurer has a very narrow definition of a "flood," which is not covered by home insurance. To an insurance company, flooding means that the water came from an overflow of a lake, stream, river or other body of water. If it didn't, don't even say the word "flood," says Sabel. If your basement is filled with water due to a burst pipe, it's not a flood — even if its depth is knee-high.
"You just have to be careful," Sabel says. "Know exactly what is in your policy, what's covered, what's not covered, and report your claim accurately."

Legendary Rangers Defenseman Brian Leetch Headlines Hall of Fame Class
The greatest player the Rangers have ever produced will take his rightful place among the greats of the game.
In an announcement that has been scheduled ever since Brian Leetch hung up his skates three years ago, the Hockey Hall of Fame officially elected the legendary Ranger defenseman to its formidable Class of 2009. Leetch will join Steve Yzerman, Brett Hull and Luc Robitaille at the induction ceremony on Nov.9 in Toronto.
The 18-member selection committee also tabbed Lou Lamoriello for induction in the builders' category, which the Devils president called "a complete surprise" - the only one of the day, in fact.
"A pretty overwhelming day, to say the least. I'm certainly humbled, excited, proud," Leetch said on a conference call, later adding that he was perhaps relieved above all. "And congratulations to the rest of the guys (elected) today. Just an amazing thing."
Leetch, the Rangers' top pick in the 1986 draft, joined the team in 1988 after stints with Boston College and the U.S. Olympic team, and won the Calder Trophy as the top rookie the following season. He played 17 seasons in a Blueshirt, covering 1,129 games - nine fewer than Harry Howell's team record - scoring 240 goals and 981 points (second on the team list to Rod Gilbert) while establishing himself as one of the best two-way defensemen in history.
Leetch won Norris Trophies in 1992 and '97, and cemented his place in Ranger lore by taking home the Conn Smythe Trophy as the 1994 playoff MVP when the Blueshirts broke their 54-year Stanley Cup drought.
Leetch, 41, was driving in his car yesterday afternoon when a call came into his cell phone from a number with a Toronto area code - meaning good news was on its way from Hall chairman Bill Hay. "I pulled my car over, took the call from Bill, and then sat there for another 15 minutes or so," Leetch said. "It was a sigh of relief."
That's a stark contrast from the call Leetch received on March 3, 2004, when Glen Sather's number on his caller ID made Leetch's stomach drop. The Rangers president/GM was calling that day to inform his best player that he had been traded to Toronto - a deal that devastated Leetch.
Leetch's next trip to the Garden came in 2006 in a Boston Bruins sweater; he returned again on Jan. 24, 2008, to watch his No.2 ascend to the rafters.
While Yzerman (692 goals), Hull (741) and Robitaille (668) are connected by the Cup they won together in Detroit in 2002, Leetch, Hull and Lamoriello share a bond from their Team USA days, peaking with their victory over Canada in the 1996 World Cup final. Leetch - widely regarded as the best U.S.-born defenseman - also left an impression on Lamoriello during the Rangers' epic defeat of the Devils in the '94 semis.
"I wish I couldn't comment on that, but I will," joked Lamoriello, whose Devil teams have won three Stanley Cups. "He was the catalyst for that Ranger team. His play was just extremely exceptional. We couldn't contain him."
The '09 class stacks up as one of the best to enter the Hall, although it gets a challenge from the 2007 group led by Leetch's pal Mark Messier that included Scott Stevens, Al MacInnis and Ron Francis. None of yesterday's honorees cared to compare classes.
"It's just great to be going into the Hall of Fame and joining those guys," Leetch said.

Avoid the Seven Deadly Sins of Networking and How To Avoid Them
1. Asking for an introduction when you are too busy to properly follow up. We've all been there. You learn that someone you know knows someone you want to know and you are champing at the bit. You shoot off an email without much deliberation, the person replies promptly (since you have a mutual contact), and because you're completely swamped, you find it impossible to make time to meet.
Solution: Next time you learn that one of your contacts knows someone you want to know, file that information away and tell your friend you might ask for an intro when you're less busy.
2. Sending a too-long email that asks no question. As an networking novice, this is a species I know all too well. These emails usually contain some variation of "can you help?" as the header. The body of the email rambles on, hinting at some need, but never quite articulating a question. My first instinct is to delete these emails, and if they come from a stranger, that is often what I do (encouraging dialogue with ramblers can only lead to no good.) If I can see the bones of a question beneath the layers of fat (or if the sender is a friend of someone I know), I try to figure out what the person is looking for and answer the question I think is being asked.
Solution: When asking someone for advice, for an informational interview or for any other help by email, write a succinct note and be clear about what you are asking for.
3. Making introductions on behalf of people you can't vouch for. We all want to help people find new opportunities, but it can be damaging to your relationships and reputation to recommend people when you can't vouch for them. LinkedIn, which has automated the process of making introductions through mutual contacts, has made this problem more prevalent.
Solution: Next time a friend asks you to make an introduction on behalf of someone you don't know, instead of blindly recommending the person, ask your friend if he or she can provide a rave review. If the answer is yes, then you can tell your contact that while you don't have firsthand knowledge, someone you respect has given the person a strong review. If the answer is no, then your friend will certainly understand if you decline to make the introduction.
4. Making incorrect assumptions. This rule gets violated in many ways, but the most common is when you assume that you know what someone else wants -- in a job search, in building a business, in adding people to a network -- so you take some action designed to help without checking first to see if your efforts would be appreciated. Meddling relatives are experts at this.
Solution: Next time you have a brilliant idea for someone else's business, job search, or networking, ask first before you take any steps to help.
5. Using a social network without knowing how it works. Lots of attention has been paid to young people behaving badly on social networks. But what about middle-aged folks who join Facebook and don't realize that a wall posting is not a private message or that it is common courtesy on Twitter to acknowledge someone when you "retweet" one of their messages.
Solution: When you join a new social network, read up or watch an online tutorial on how it works and be an observer for a little while before diving in. If you make a misstep even when you know the rules, find an appropriate way to acknowledge your error.
6. Failing to properly follow up. If someone takes the time to help you in any way -- giving an informational interview, making an introduction, reviewing your resume, sending you a new client -- remember to follow up and give proper thanks. In most cases, a quick email, hand-written note or call will suffice. But what if you feel greater thanks are in order?
Solution: Send an Amazon gift card -- it's something practically anyone would appreciate and you can order it and have it delivered by email with a few clicks of the mouse. If you're strapped for cash, consider recommending the person on LinkedIn (assuming you're both on LinkedIn, and who isn't these days?)
7. Sending unwieldy attachments or too many samples of your work. If you're asking someone for advice and including samples of your work, make it as easy as possible for the person to review those samples. Rather than including attachments, which can be burdensome to open, try to include links to URLs. Free services like LinkedIn or VisualCV allow you to create an online version of your resume that includes a URL that you can selectively share. (I believe these new age resumes will soon completely replace the old-fashioned paper variety.) If you have a portfolio, set up a simple website to showcase your work.
Do you have any pet networking peeves -- and suggestions for how to avoid them? If so, please share in the comments.

A Closer Look: Cause of Death
"As it must to all men, death came to Charles Foster Kane in one of the most famous movies of all time," filmmaker George Lucas writes in the book's introduction. "The eloquence of that notion -- that death will come to every single one of us -- has always been a bit of a morbid fascination for me. But is it really so morbid to be curious about the only thing in this world that is truly certain?.... But death is truth -- and its undeniably fascinating. So, I hope that Cause of Death will intrigue, inform, illuminate and perhaps even inspire you to action -- because when we learn a little about how we die, we also learn a lot about how we live."
Author Lucy Autrey Wilson, who fans might recall began her career with Lucasfilm in 1974 when she typed the script to the first Star Wars movie on an IBM Selectric typewriter, talks with Starwars.com about why George Lucas asked her to research a book about a topic most of us would rather avoid altogether.
How did the Cause of Death book project come about? Why did George Lucas want a comprehensive book of statistics and facts about all the ways humans can die?
In November 2000, in an interview between George Lucas and Tom Grace, George fleshed out his interest in a book that would provide "real" numbers and information on causes of death instead of the "funny" numbers one finds every time you read a newspaper or magazine. He thought providing people with the truth about death statistics would be both useful and entertaining. His good friend Jim Henson had died suddenly May 1990 from a bacterial infection. Because Henson traveled a lot, George had wondered if he caught the bug that killed him in an airport and that led to wondering what the most deadly diseases in the world really were. Tom had volunteered to write and research causes of death thinking it would provide good background for one of his thriller novels. The plan was for him to use his brother's proprietary software to search and find all the desired data online so the book could be put together quickly. Who knew, however, that finding accurate information on what a driver was doing when he crashed his car and was killed, or whether a virus is deadlier than bacteria, or whether people in war died more often of disease or gunshots, or which is the deadliest animal in Africa, etc. would be so much work!
How did you start tackling the research for this project?
My success with publishing Star Wars was to put the various projects into the right hands, which included a team of people who could provide the writers with the research and background they needed. After a year of death research that didn't even dent the surface of what George Lucas was interested in, Tom Grace left the project. By then I knew the book had to hinge on a consistent framework so the numbers being compared were apples to apples and not just random facts that didn't relate to each other. Tom had uncovered the databases maintained by the World Health Organization (WHO) and we had broken down all deaths into interesting groupings. Similarly, the U.S. mortality statistics reported by the Center for Disease Control (CDC) were synced up to the numbers reported by the WHO. What had become clear was that one couldn't count on online newspapers, bloggers or others to always have their facts straight. We needed to get the bulk of our data from more reliable sources -- i.e. via viable governmental agencies that have massive teams of people to report and track statistics.
With the help of another writer/researcher Jane Ellen Stevens, official sources for stats beyond the WHO and CDC were revealed from the United Nations to the National Highway Traffic Safety Administration to Medline (part of the National Library of Medicine which helped enormously in turning medical terminology into "English" ) to the Bureau of Labor Statistics etc. With a framework of related death numbers reported by both the WHO and the CDC, now research needed to be done via hundreds of databases that would uncover answers to the questions George was asking. By 2004, completely hooked on the subject, and realizing I needed to know the data as well as any contributing researcher in order to edit the final book, I decided the only way to get the project done was to do the bulk of the remaining research myself and hire word-smiths who could then turn the facts into fun.
How did the Internet help with your research?
Without the Internet there would be no book. Thank heavens for Google! And thank heavens for how much all governmental agencies worldwide were uploading and making information accessible between when the research first started in 2001 to when it became intense in 2004. This is one area our tax dollars are really put to good use. Once the numbers, for example, for all worldwide and U.S. accidental deaths were known, then one needed to drill down to find the cause (cell phone or speeding, ladder or hot water, etc.). But when it came to certain areas, it wasn't easy. Neither the CDC nor the WHO list deaths by whether they were caused by a water buffalo or a hippo (in fact most deaths in Africa, China and other countries are best guesses). Nor do they include information on whether someone died being hit or struck while playing baseball or football. So, to flesh out the chapters on Accidental death by Flora and Fauna, Nature and Sports, for example, required coming up with a list of everything to be included (i.e. for Flora and Fauna, a list of mammals, birds, reptiles, insects, marine animals, and flora A to Z) and then doing a Google search on each creature on the list to find out as much info as was out there on people killed by that particular agent.
What statistic or fact did you learn in writing this book that surprised you the most?
I probably spent the most research time on death by Flora and Fauna and Bugs. What surprised me in the Flora and Fauna section is that although death by shark attacks, mountain lions, bears, etc. are always front page news, we don't die very often from the creatures we share the planet with. In fact, it made me really sad to realize how many of these creatures man has managed to wipe out. In researching accidental deaths from motor vehicles, I was surprised by how many pedestrians are killed annually (I'm now very careful when I cross the street) and in researching death by Bugs (bacteria, viruses, fungi, parasites and prions), I never fully realized how truly nasty those little microscopic creatures really are (especially if one has a weakened immune system). So, I'm now very good about washing my hands.
Which section of the book is your favorite and why?
I like Accidental deaths by Flora and Fauna and Bugs the best because they were the hardest to figure out and the most interesting. While I was working on the book, people were always asking me if I found the subject really depressing. The answer is no. What was increasingly refreshing was the realization that almost all premature deaths are preventable if you follow general guidelines (wash your hands, exercise, watch what you eat, etc.). That led to a decision to rank the deaths in the book by whether they happen prematurely rather than when one takes all ages into account. What was also uplifting is how much we've improved our average life spans since my parent's generation with inventions like seat belts, bike helmets and improved medicines.
What's the weirdest way to die?
One of the weirdest (and saddest) ways to die is from Scleroderma which killed one of my favorite painters, Paul Klee, and also a very sweet fellow Lucasfilm staffer many years ago. It's very rare, (only one person died of it in the U.S. in each of 2004 and 2005). It's a form of arthritis that causes the skin all over your body to become progressively hardened.
What's the most common way to die?
The most common way to die is by self inflicting your body with too much of the wrong substances (tobacco, high cholesterol foods, high fructose corn syrup, alcohol, etc.) which raise the probability you'll die from some kind of cancer or organ failure.
Why do you think this book will be helpful to readers, as well as entertaining?
I think Robert Young Pelton's introduction sums it up pretty well. It is an active body and inquisitive mind that keeps us young. We are all going to die, but we can live life longer and more fully by doing simple things like wearing a seatbelt, skipping dessert and never smoking. I hope the reader, rather than brood about all the horrible things that can kill you (or has just killed someone you read about daily in magazines and newspapers), will be careful to avoid the bad things that are within their control and go out and have a good time.
Can you talk a little bit about how George Lucas Books was created and why?
In 1999, I had been running the Lucas Licensing Publishing Department for about 10 years when George Lucas first mentioned he was interested in books on subjects that had nothing to do with Star Wars. Even though packaging and licensing books on our own popular movie properties was very different from developing factual nonfiction, I believe in the saying "Where there's a will there's a way" and took on the challenge of turning George's interests into books. One of the books was to be on causes of death and other general film-related books were also planned. So with one author already on board to research and write the death book, I hired Jonathan Rinzler to help edit the new nonfiction. That same year, we made a five-book deal with Ballantine to publish the new imprint nonfiction titles. The plan was to develop these books together with our publishing partner while continuing with our regular licensed projects. Each nonfiction book would have one author to both do the research and write.
Starting with one or two Star Wars titles per year in the late 1980s, the Lucasfilm publishing program had been built up so by the early 2000's we were publishing between 100 and 200 mostly Star Wars books, magazines and comic titles per year. When it became clear the new nonfiction was going to take a lot more time than anticipated, I left Licensing in August 2003 to join JAK Films and manage the new imprint as a department of one. Over time I realized most authors who are good with words are not that good with numbers and the one author-one book approach wasn't producing the desired results. Eventually, the arrangement with Ballantine was dissolved as unworkable and JAK Films moved forward packaging and publishing each title individually. That resulted in the very fine team at Simon & Schuster becoming the Cause of Death book's publisher and contributing the really great book design.
Cause of Death: A Perfect Little Guide to What Kills Us by Lucy Autrey Wilson, Jack Mingo and Erin Barrett, a new book from George Lucas Books and Simon & Schuster is on shelves in bookstores nationwide.
Home Owners and Renters Insurance
Home Owners and Renters Insurance
The property damage portion of a homeowner's policy covers loss or damage to the home and other structures on the property. In the event of a total loss, the amount paid depends upon the dwelling policy limit of the insurance contract as well as the type of coverage provided under the contract.
On some policies, other structures (such as detached garages, tool sheds, fences, guesthouses, and gazebos) are typically covered at the rate of 10% of the limit set for the dwelling itself. For example, an insurance contract that provides $100,000 coverage for a dwelling typically will provide up to $10,000 coverage for other structures. Trees, shrubbery and other landscape are typically covered for 5% of the dwelling limit.
Know your policy, talk to your insurance agent, they are your friend.
How to Live by the Numbers: Health
Unless popcorn shrimp is on offer, many Americans are loath to walk any more than necessary. That chronic sloth is a drag for employers, whose health care costs can swell in tandem with their workers' waistlines. Now Virgin impresario Richard Branson thinks he can save businesses a bundle with a program that turns personal fitness into a game, complete with reams of stats to obsess over. When companies sign up with Virgin HealthMiles, their employees rack up rewards for staying active: The more you walk, the closer you get to earning HealthCash, which can be redeemed for real cash or gift cards from Amazon.com, Target, and (curiously) Omaha Steaks.
Participants are issued pedometers and challenged to take 7,000 steps a day. That's about 3.5 miles—40 percent more than the average deskbound adult's daily distance. Hitting that goal in a day garners 20 HealthMiles, the program's equivalent of frequent flier points. Bonuses are available for simply logging in to the HealthMiles Web site (10 miles), taking a no-smoking pledge (500 miles), or updating your blood pressure, weight, and body fat at a HealthMiles kiosk (200 miles).
I gave it a go and found that once my routine perambulation was assigned a numerical value—and valuable gifts were on the line—I began dedicating inordinate effort to meet that 7,000-step target. At first, I was aghast to learn that despite my 25-minute trudge to the office, I averaged only 6,600 steps per day. The problem? I'm tall, and my legs are longer than average. So I shortened my stride.
Alas, I'm still nowhere near reaching HealthMiles' vaunted Level Five, which pays $500 in HealthCash. Employers that offer the program pick up that tab, but it could be a worthwhile investment: Virgin CEO Christopher Boyce claims that corporate clients can cut $2,500 off the annual cost of health care provided to each participant. Imagine how much more they'll save if Virgin ever develops a pedometer capable of stopping people from walking into a Dunkin' Donuts.

Face Gets Shutout, Then Shuts Game Off
I like to play video games in my spare time. I feel comfortable saying that knowing I am not in the minority. I am 33 years of age and I am the average age of a video game player. Video games are not for just kids anymore. The video game industry is a multi-billion dollar industry. And it continues to grow every month. It was even put into the Patriot Act that the government can listen into the conversations on XBox Live without a warrant for fear of terrorists using the platform to organize and plan attacks against us. It is a cheap way to communicate all over the world. For the price of an XBox360, a broadband connection, and a recurring $50 yearly charge, you can talk to people all over the world as long as you and the person you are trying to connect to are signed in to XBox Live. And you can have up to 8 people in your "party." When I was in Rhode Island, this was my saving grace. Because I could still sign in and hangout with my brother and friends on Long Island when I wanted.
I usually play video games with a core group of guys that all went to High School with me. I know this might sound funny to the non-gamers but the competition can get, whats the nicest way I can put this.......heated. A lot of yelling and screaming at each other. Some cursing I wont lie. Arguments between friends can carry over for a few days. It can even carry over to the golf course. And the bragging rights are really what it is for. So you can talk trash to each other.
And this is the ultimate trash talk. For everyone to see. So on that note, me and my buddy Face, we don't call him Face because of the A-Team just a nickname given to him high school, have been playing this hockey game. We are the only two out of our friends that play it because we beat everyone else. Very old school Nintendo style with the fat, medium, and skinny guys. Great game. But we have Mastered this game so much that the competition gets very, very heated. I'll give him credit, we played a best of seven of seven tournament. Which is we play a best 4 out 7 tournament and count that as one game in a best 4 tournaments out of 7 tournaments. And he won. Beat me 4 tournaments to 2.
But then things have changed. I have beaten him 14 straight at one point. The only thing we had to play for against each other is that neither one of us had shut the other person out. And that is the main reason why I posted this. We played a few weeks ago and we were having connection problems. The service kept booting us in the middle of the games. The last game we played that night, I was winning 8-0. Never got that close to shutting him out. I scored my 9th goal, and the game crashed. Thankfully I live alone so nobody could hear me scream. He swore he didn't do it and it was the game. I knew he did. And I was pissed. It took us about a week before we really talked. He kept saying he didn't shut the game off and it was XBox Live. So I let it pass.
I got home from work last night about 7pm. Wasn't planing on going out as I had to be in my office early this morning. Face and I were going to play a game of hockey and then play Tiger Woods Golf on Bethpage Black. I called it before the hockey game that I had figured him out and he was going to get shutout this game. Again, I had him 8-0. And just as I scored my 9th goal, he shut the game off. I wasn't pissed this time. I laughed. Now I know, I shut him out............
Green Tip Of the Day
Put green plants in your home. Studies suggest that for a 2000 square foot home, you will need as many as 15 plants to receive the optimal benefits. Aside from cheering up a room, house plants improve the indoor air quality in your home by absorbing toxic gases from your computer and electronic equipment. They also help maintain humidity.
Many houseplants are easy to maintain. Be sure to choose plants that will grow well in your home by considering how much direct sunlight and attention they will need. Get one for your office too!
* If you have a toddler in your home who enjoys unplanting your house plants, try hanging the plants out of reach.

A Brief Guide to Mold in the Workplace
Introduction
Concern about indoor exposure to mold has increased along with public awareness that exposure to mold can cause a variety of health effects and symptoms, including allergic reactions. This safety and health information bulletin provides recommendations for the prevention of mold growth and describes measures designed to protect the health of building occupants and workers involved in mold cleanup and prevention. This bulletin is directed primarily at building managers, custodians, and others responsible for building maintenance, but may also be used as a basic reference for those involved in mold remediation. By reading this safety and health information bulletin, individuals with little or no experience with mold remediation may be able to reasonably judge whether mold contamination can be managed in-house or whether outside assistance is required. The advice of a medical professional should always be sought if there are any emerging health issues. This document will help those responsible for building maintenance in the evaluation of remediation plans. Contractors and other professionals (e.g. industrial hygienists or other environmental health and safety professionals) who respond to mold and moisture situations in buildings, as well as members of the general public, also may find these guidelines helpful. The information in these guidelines is intended only as a summary of basic procedures and is not intended, nor should it be used, as a detailed guide to mold remediation.
These guidelines are subject to change as more information regarding mold contamination and remediation becomes available.
Mold Basics
Molds are part of the natural environment. Molds are fungi that can be found anywhere - inside or outside - throughout the year. About 1,000 species of mold can be found in the United States, with more than 100,000 known species worldwide. Outdoors, molds play an important role in nature by breaking down organic matter such as toppled trees, fallen leaves, and dead animals. We would not have food and medicines, like cheese and penicillin, without mold.
Indoors, mold growth should be avoided. Problems may arise when mold starts eating away at materials, affecting the look, smell, and possibly, with the respect to wood-framed buildings, affecting the structural integrity of the buildings. Molds can grow on virtually any substance, as long as moisture or water, oxygen, and an organic source are present. Molds reproduce by creating tiny spores (viable seeds) that usually cannot be seen without magnification. Mold spores continually float through the indoor and outdoor air. Molds are usually not a problem unless mold spores land on a damp spot and begin growing. They digest whatever they land on in order to survive. There are molds that grow on wood, paper, carpet, foods and insulation, while other molds feast on the everyday dust and dirt that gather in the moist regions of a building. When excessive moisture or water accumulates indoors, mold growth often will occur, particularly if the moisture problem remains uncorrected.
While it is impossible to eliminate all molds and mold spores, controlling moisture can control indoor mold growth. All molds share the characteristic of being able to grow without sunlight; mold needs only a viable seed (spore), a nutrient source, moisture, and the right temperature to proliferate. This explains why mold infestation is often found in damp, dark, hidden spaces; light and air circulation dry areas out, making them less hospitable for mold. Molds gradually damage building materials and furnishings. If left unchecked, mold can eventually cause structural damage to a wood framed building, weakening floors and walls as it feeds on moist wooden structural members. If you suspect that mold has damaged building integrity, consult a structural engineer or other professional with the appropriate expertise. Since mold requires water to grow, it is important to prevent excessive moisture in buildings.
Some moisture problems in buildings have been linked to changes in building construction practices since the 1970s, which resulted in tightly sealed buildings with diminished ventilation, contributing to moisture vapor buildup. Other moisture problems may result from roof leaks, landscaping or gutters that direct water into or under a building, or unvented combustion appliance. Delayed or insufficient maintenance may contribute to moisture problems in buildings. Improper maintenance and design of building heating/ventilating/air-conditioning (HVAC) systems, such as insufficient cooling capacity for an air conditioning system, can result in elevated humidity levels in a building.
Health Effects
Currently, there are no federal standards or recommendations, (e.g., OSHA, NIOSH, EPA) for airborne concentrations of mold or mold spores. Scientific research on the relationship between mold exposures and health effects is ongoing. This section provides a brief overview, but does not describe all potential health effects related to mold exposure. For more detailed information, consult a health professional or your state or local health department.
There are many types of mold. Most typical indoor air exposures to mold do not present a risk of adverse health effects. Molds can cause adverse effects by producing allergens (substances that can cause allergic reactions). Potential health concerns are important reasons to prevent mold growth and to remediate existing problem areas. The onset of allergic reactions to mold can be either immediate or delayed. Allergic responses include hay fever-type symptoms such as runny nose and red eyes. Molds may cause localized skin or mucosal infections but, in general, do not cause systemic infections in humans, except for persons with impaired immunity, AIDS, uncontrolled diabetes, or those taking immune suppressive drugs. An important reference with guidelines for immuno-compromised individuals can be found at the Centers for Disease Control and Prevention (CDC) website.
Molds can also cause asthma attacks in some individuals who are allergic to mold. In addition, exposure to mold can irritate the eyes, skin, nose and throat in certain individuals. Symptoms other than allergic and irritant types are not commonly reported as a result of inhaling mold in the indoor environment. Some specific species of mold produce mycotoxins under certain environmental conditions. Potential health effects from mycotoxins are the subject of ongoing scientific research and are beyond the scope of this document. Eating, drinking, and using tobacco products and cosmetics where mold remediation is taking place should be avoided. This will prevent unnecessary contamination of food, beverage, cosmetics, and tobacco products by mold and other harmful substances within the work area.
Prevention
Moisture control is the key to mold control. When water leaks or spills occur indoors - act promptly. Any initial water infiltration should be stopped and cleaned promptly.
A prompt response (within 24-48 hours) and thorough clean- up, drying, and/or removal of water-damaged materials will prevent or limit mold growth. Mold prevention tips include:
Repairing plumbing leaks and leaks in the building structure as soon as possible.
Looking for condensation and wet spots. Fix source(s) of moisture incursion problem(s) as soon as possible.
Preventing moisture from condensing by increasing surface temperature or reducing the moisture level in the air (humidity). To increase surface temperature, insulate or increase air circulation. To reduce the moisture level in the air, repair leaks, increase ventilation (if outside air is cold and dry), or dehumidify (if outdoor air is warm and humid).
Keeping HVAC drip pans clean, flowing properly, and unobstructed.
Performing regularly scheduled building/ HVAC inspections and maintenance, including filter changes.
Maintaining indoor relative humidity below 70% (25 - 60%, if possible).
Venting moisture-generating appliances, such as dryers, to the outside where possible.
Venting kitchens (cooking areas) and bathrooms according to local code requirements.
Cleaning and drying wet or damp spots as soon as possible, but no more than 48 hours after discovery.
Providing adequate drainage around buildings and sloping the ground away from building foundations. Follow all local building codes.
Pinpointing areas where leaks have occurred, identifying the causes, and taking preventive action to ensure that they do not reoccur.
Questions That May Assist in Determining Whether a Mold Problem Currently Exists
Are building materials or furnishings visibly moisture damaged?
Have building materials been wet more than 48 hours?
Are there existing moisture problems in the building?
Are building occupants reporting musty or moldy odors?
Are building occupants reporting health problems that they think are related to mold in the indoor environment?
Has the building been recently remodeled or has the building use changed?
Has routine maintenance been delayed or the maintenance plan been altered?
Always consider consulting a health professional to address any employee health concerns.
Remediation Plan
Remediation includes both the identification and correction of the conditions that permit mold growth, as well as the steps to safely and effectively remove mold damaged materials. Before planning the remediation assess the extent of the mold or moisture problem and the type of damaged materials. If you choose to hire outside assistance to do the cleanup, make sure the contractor has experience with mold remediation. Check references and ask the contractor to follow the recommendations in EPA’s publication, “Mold Remediation in Schools and Commercial Buildings,” or other guidelines developed by professional or governmental organizations. The remediation plan should include steps to permanently correct the water or moisture problem. The plan should cover the use of appropriate personal protective equipment (PPE). It also should include steps to carefully contain and remove moldy building materials in a manner that will prevent further contamination. Remediation plans may vary greatly depending on the size and complexity of the job, and may require revision if circumstances change or new facts are discovered. If you suspect that the HVAC system is contaminated with mold, or if mold is present near the intake to the system, contact the National Air Duct Cleaners Association (NADCA), or consult EPA’s guide, “Should You Have the Air Ducts in Your Home Cleaned?” before taking further action. Do not run the HVAC system if you know or suspect that it is contaminated with mold, as it could spread contamination throughout the building.
If the water or mold damage was caused by sewage or other contaminated water, consult a professional who has experience cleaning and repairing buildings damaged by contaminated water. The remediation manager’s highest priority must be to protect the health and safety of the building occupants and remediators. Remediators should avoid exposing themselves and others to mold-laden dusts as they conduct their cleanup activities. Caution should be used to prevent mold and mold spores from being dispersed throughout the air where they can be inhaled by building occupants.
In some cases, especially those involving large areas of contamination, the remediation plan may include temporary relocation of some or all of the building occupants. When deciding if relocating occupants is necessary, consideration should be given to the size and type of mold growth, the type and extent of health effects reported by the occupants, the potential health risks that could be associated with the remediation activity, and the amount of disruption this activity is likely to cause. In addition, before deciding to relocate occupants, one should also evaluate the remediator’s ability to contain/minimize possible aerosolization of mold spores given their expertise and the physical parameters of the workspace.
When possible, remediation activities should be scheduled during off hours when building occupants are less likely to be affected. Remediators, particularly those with health related concerns, may wish to check with their physicians or other health-care professionals before working on mold remediation or investigating potentially moldy areas. If any individual has health concerns, doubts, or questions before beginning a remediation/cleanup project, he or she should consult a health professional.
Mold Remediation/Cleanup Methods
The purpose of mold remediation is to correct the moisture problem and to remove moldy and contaminated materials to prevent human exposure and further damage to building materials and furnishings. Porous materials that are wet and have mold growing on them may have to be discarded because molds can infiltrate porous substances and grow on or fill in empty spaces or crevices. This mold can be difficult or impossible to remove completely. As a general rule, simply killing the mold, for example, with biocide is not enough. The mold must be removed, since the chemicals and proteins, which can cause a reaction in humans, are present even in dead mold. A variety of cleanup methods are available for remediating damage to building materials and furnishings caused by moisture control problems and mold growth. The specific method or group of methods used will depend on the type of material affected. Some methods that may be used include the following:
Wet Vacuum
Wet vacuums are vacuum cleaners designed to collect water. They can be used to remove water from floors, carpets, and hard surfaces where water has accumulated. They should not be used to vacuum porous materials, such as gypsum board. Wet vacuums should be used only on wet materials, as spores may be exhausted into the indoor environment if insufficient liquid is present. The tanks, hoses, and attachments of these vacuums should be thoroughly cleaned and dried after use since mold and mold spores may adhere to equipment surfaces.
Damp Wipe
Mold can generally be removed from nonporous surfaces by wiping or scrubbing with water and detergent. It is important to dry these surfaces quickly and thoroughly to discourage further mold growth. Instructions for cleaning surfaces, as listed on product labels, should always be read and followed.
HEPA Vacuum
HEPA (High-Efficiency Particulate Air) vacuums are recommended for final cleanup of remediation areas after materials have been thoroughly dried and contaminated materials removed. HEPA vacuums also are recommended for cleanup of dust that may have settled on surfaces outside the remediation area. Care must be taken to assure that the filter is properly seated in the vacuum so that all the air passes through the filter. When changing the vacuum filter, remediators should wear respirators, appropriate personal protective clothing, gloves, and eye protection to prevent exposure to any captured mold and other contaminants. The filter and contents of the HEPA vacuum must be disposed of in impermeable bags or containers in such a way as to prevent release of the debris.
Disposal of Damaged Materials
Building materials and furnishings contaminated with mold growth that are not salvageable should be placed in sealed impermeable bags or closed containers while in the remediation area. These materials can usually be discarded as ordinary construction waste. It is important to package mold-contaminated materials in this fashion to minimize the dispersion of mold spores. Large items with heavy mold growth should be covered with polyethylene sheeting and sealed with duct tape before being removed from the remediation area. Some jobs may require the use of dust-tight chutes to move large quantities of debris to a dumpster strategically placed outside a window in the remediation area.
Use of Biocides
The use of a biocide, such as chlorine bleach, is not recommended as a routine practice during mold remediation, although there may be instances where professional judgment may indicate its use (for example, when immuno-compromised individuals are present). In most cases, it is not possible or desirable to sterilize an area, as a background level of mold spores comparable to the level in outside air will persist. However, the spores in the ambient air will not cause further problems if the moisture level in the building has been corrected. Biocides are toxic to animals and humans, as well as to mold.
If you choose to use disinfectants or biocides, always ventilate the area, using outside air if possible, and exhaust the air to the outdoors. When using fans, take care not to extend the zone of contamination by distributing mold spores to a previously unaffected area. Never mix chlorine bleach solution with other cleaning solutions or detergents that contain ammonia because this may produce highly toxic vapors and create a hazard to workers. Some biocides are considered pesticides, and some states require that only registered pesticide applicators apply these products in schools, commercial buildings, and homes. Make sure anyone applying a biocide is properly licensed where required. Fungicides are commonly applied to outdoor plants, soil, and grains as a powder or spray. Examples of fungicides include hexachlorobenzene, organomercurials, pentachlorophenol, phthalimides, and dithiocarbamates.
Do not use fungicides developed for outdoor use in any indoor application, as they can be extremely toxic to animals and humans in an enclosed environment. When you use biocides as a disinfectant or a pesticide, or as a fungicide, you should use appropriate PPE, including respirators. Always, read and follow product label precautions. It is a violation of Federal (EPA) law to use a biocide in any manner inconsistent with its label direction.
Mold Remediation Guidelines
This section presents remediation guidelines for building materials that have or are likely to have mold growth. The guidelines are designed to protect the health of cleanup personnel and other workers during remediation. These guidelines are based on the size of the area impacted by mold contamination. Please note that these are guidelines; some professionals may prefer other remediation methods, and certain circumstances may require different approaches or variations on the approaches described below. If possible, remediation activities should be scheduled during off-hours when building occupants are less likely to be affected. Although the level of personal protection suggested in these guidelines is based on the total surface area contaminated and the potential for remediator or occupant exposure, professional judgment always should play a part in remediation decisions.
These remediation guidelines are based on the size of the affected area to make it easier for remediators to select appropriate techniques, not on the basis of research showing there is a specific method appropriate at a certain number of square feet.
The guidelines have been designed to help construct a remediation plan. The remediation manager should rely on professional judgment and experience to adapt the guidelines to particular situations. When in doubt, caution is advised. Consult an experienced mold remediator for more information.
Level I: Small Isolated Areas (10 sq. ft or less) - e.g., ceiling tiles, small areas on walls.
Remediation can be conducted by the regular building maintenance staff as long as they are trained on proper clean-up methods, personal protection, and potential health hazards. This training can be performed as part of a program to comply with the requirements of the OSHA Hazard Communication Standard (29 CFR 1910.1200).
Respiratory protection (e.g., N-95 disposable respirator) is recommended. Respirators must be used in accordance with the OSHA respiratory protection standard (29 CFR 1910.134). Gloves and eye protection should be worn.
The work area should be unoccupied. Removing people from spaces adjacent to the work area is not necessary, but is recommended for infants (less than 12 months old), persons recovering from recent surgery, immune-suppressed people, or people with chronic inflammatory lung diseases (e.g., asthma, hypersensitivity pneumonitis, and severe allergies).
Containment of the work area is not necessary. Dust suppression methods, such as misting (not soaking) surfaces prior to remediation, are recommended.
Contaminated materials that cannot be cleaned should be removed from the building in a sealed impermeable plastic bag. These materials may be disposed of as ordinary waste.
The work area and areas used by remediation workers for egress should be cleaned with a damp cloth or mop and a detergent solution.
All areas should be left dry and visibly free from contamination and debris.
Level II: Mid-Sized Isolated Areas (10-30 sq. ft.) – e.g., individual wallboard panels.
Remediation can be conducted by the regular building maintenance staff. Such persons should receive training on proper clean-up methods, personal protection, and potential health hazards. This training can be performed as part of a program to comply with the requirements of the OSHA Hazard Communication Standard (29 CFR 1910.1200).
Respiratory protection (e.g., N-95 disposable respirator) is recommended. Respirators must be used in accordance with the OSHA respiratory protection standard (29 CFR 1910.134). Gloves and eye protection should be worn.
The work area should be unoccupied. Removing people from spaces adjacent to the work area is not necessary, but is recommended for infants (less than 12 months old), persons recovering from recent surgery, immune-suppressed people, or people with chronic inflammatory lung diseases (e.g., asthma, hypersensitivity pneumonitis, and severe allergies).
Surfaces in the work area that could become contaminated should be covered with a secured plastic sheet(s) before remediation to contain dust/debris and prevent further contamination.
Dust suppression methods, such as misting (not soaking) surfaces prior to remediation, are recommended.
Contaminated materials that cannot be cleaned should be removed from the building in a sealed impermeable plastic bag. These materials may be disposed of as ordinary waste.
The work area and areas used by remediation workers for egress should be HEPA vacuumed and cleaned with a damp cloth or mop and a detergent solution.
All areas should be left dry and visibly free from contamination and debris.
Level III: Large Isolated Areas (30 –100 square feet) – e.g., several wallboard panels. Industrial hygienists or other environmental health and safety professionals with experience performing microbial investigations and/or mold remediation should be consulted prior to remediation activities to provide oversight for the project.
The following procedures may be implemented depending upon the severity of the contamination:
It is recommended that personnel be trained in the handling of hazardous materials and equipped with respiratory protection (e.g., N-95 disposable respirator). Respirators must be used in accordance with the OSHA respiratory protection standard (29 CFR 1910.134). Gloves and eye protection should be worn.
Surfaces in the work area and areas directly adjacent that could become decontaminated should be covered with a secured plastic sheet(s) before remediation to contain dust/ debris and prevent further contamination.
Seal ventilation ducts/grills in the work area and areas directly adjacent with plastic sheeting.
The work area and areas directly adjacent should be unoccupied. Removing people from spaces near the work area is recommended for infants, persons having undergone recent surgery, immunesuppressed people, or people with chronic inflammatory lung diseases. (e.g., asthma, hypersensitivity pneumonitis, and severe allergies).
Dust suppression methods, such as misting (not soaking) surfaces prior to mediation, are recommended.
Contaminated materials that cannot be cleaned should be removed from the building in sealed impermeable plastic bags. These materials may be disposed of as ordinary waste.
The work area and surrounding areas should be HEPA vacuumed and cleaned with a damp cloth or mop and a detergent solution.
All areas should be left dry and visibly free from contamination and debris.
Note: If abatement procedures are expected to generate a lot of dust (e.g., abrasive cleaning of contaminated surfaces, demolition of plaster walls) or the visible concentration of the mold is heavy (blanket coverage as opposed to patchy), it is recommended that the remediation procedures for Level IV be followed.
Level IV: Extensive Contamination (greater than 100 contiguous square feet in an area).
Industrial hygienists or other environmental health and safety professionals with experience performing microbial investigations and/or mold remediation should be consulted prior to remediation activities to provide oversight for the project.
The following procedures may be implemented depending upon the severity of the contamination:
Personnel trained in the handling of hazardous materials and equipped with:
Full face piece respirators with HEPA cartridges;
Disposable protective clothing covering entire body including both head and shoes; and
Gloves.
Containment of the affected area:
Complete isolation of work area from occupied spaces using plastic sheeting sealed with duct tape (including ventilation ducts/grills, fixtures, and other openings);
The use of an exhaust fan with a HEPA filter to generate negative pressurization; and
Airlocks and decontamination room.
If contaminant practices effectively prevent mold from migrating from affected areas, it may not be necessary to remove people from surrounding work areas. However, removal is still recommended for infants, persons having undergone recent surgery, immune- suppressed people, or people with chronic inflammatory lung diseases. (e.g., asthma, hypersensitivity pneumonitis, and severe allergies).
Contaminated materials that cannot be cleaned should be removed from the building in sealed impermeable plastic bags. The outside of the bags should be cleaned with a damp cloth and a detergent solution or HEPA vacuumed in the decontamination chamber prior to their transport to uncontaminated areas of the building. These materials may be disposed of as ordinary waste.
The contained area and decontamination room should be HEPA vacuumed and cleaned with a damp cloth or mopped with a detergent solution and be visibly clean prior to the removal of isolation barriers.
Personal Protective Equipment (PPE)
Any remediation work that disturbs mold and causes mold spores to become airborne increases the degree of respiratory exposure. Actions that tend to disperse mold include: breaking apart moldy porous materials such as wallboard; destructive invasive procedures to examine or remediate mold growth in a wall cavity; removal of contaminated wallpaper by stripping or peeling; using fans to dry items or ventilate areas. The primary function of personal protective equipment is to prevent the inhalation and ingestion of mold and mold spores and to avoid mold contact with the skin or eyes. The following sections discuss the various types of PPE that may be used during remediation activities. Skin and Eye Protection Gloves protect the skin from contact with mold, as well as from potentially irritating cleaning solutions. Long gloves that extend to the middle of the forearm are recommended. The glove material should be selected based on the type of substance/ chemical being handled.
If you are using a biocide such as chlorine bleach, or a strong cleaning solution, you should select gloves made from natural rubber, neoprene, nitrile, polyurethane, or PVC. If you are using a mild detergent or plain water, ordinary household rubber gloves may be used. To protect your eyes, use properly fitted goggles or a full face piece respirator. Goggles must be designed to prevent the entry of dust and small particles. Safety glasses or goggles with open vent holes are not appropriate in mold remediation. Respiratory Protection Respirators protect cleanup workers from inhaling airborne mold, contaminated dust, and other particulates that are released during the remediation process. Either a half mask or full face piece air-purifying respirator can be used. A full face piece respirator provides both respiratory and eye protection.
Please refer to the discussion of the different levels of remediation to ascertain the type of respiratory protection recommended. Respirators used to provide protection from mold and mold spores must be certified by the National Institute for Occupational Safety and Health (NIOSH). More protective respirators may have to be selected and used if toxic contaminants such as asbestos or lead are encountered during remediation.
As specified by OSHA in 29 CFR 1910.134 individuals who use respirators must be properly trained, have medical clearance, and be properly fit tested before they begin using a respirator. In addition, use of respirators requires the employer to develop and implement a written respiratory protection program, with worksite-specific procedures and elements. Protective Clothing While conducting building inspections and remediation work, individuals may encounter hazardous biological agents as well as chemical and physical hazards. Consequently, appropriate personal protective clothing (i.e., reusable or disposable) is recommended to minimize cross-contamination between work areas and clean areas, to prevent the transfer and spread of mold and other contaminants to street clothing, and to eliminate skin contact with mold and potential chemical exposures. Disposable PPE should be discarded after it is used. They should be placed into impermeable bags, and usually can be discarded as ordinary construction waste.
Appropriate precautions and protective equipment for biocide applicators should be selected based on the product manufacturer’s warnings and recommendations (e.g., goggles or face shield, aprons or other protective clothing, gloves, and respiratory protection).
Sampling for Mold
Is it necessary to sample for mold? In most cases, if visible mold growth is present, sampling is unnecessary. Air sampling for mold may not be part of a routine assessment because decisions about appropriate remediation strategies often can be made on the basis of a visual inspection. Your first step should be to inspect for any evidence of water damage and visible mold growth. Testing for mold is expensive, and there should be a clear reason for doing so. In many cases, it is not economically practical or useful to test for mold growth on surfaces or for airborne spores in the building. In addition, there are no standards for “acceptable” levels of mold in buildings, and the lack of a definitive correlation between exposure levels and health effects makes interpreting the data difficult, if not impossible.
Testing is usually done to compare the levels and types of mold spores found inside the building with those found outside of the building or for comparison with another location in the building. In addition, air sampling may provide tangible evidence supporting a hypothesis that investigators have formulated. For example, air sampling may show a higher concentration of the same species of mold when the HVAC is operating than when it has been turned off. This finding may convince the investigators that the mold is growing within, and being disseminated by, the HVAC system. Conversely, negative results may persuade investigators to abandon this hypothesis and to consider other sources of mold growth or dissemination.
If you know you have a mold problem, it is more important to spend time and resources removing the mold and solving the moisture problem that causes the moldy conditions than to undertake extensive testing for the type and quantity of mold. If you are in doubt about sampling, consult an industrial hygienist or other environmental health or safety professional with experience in microbial investigations to help you decide if sampling for mold is necessary or useful, and to identify persons who can conduct any necessary sampling.
Due to the wide difference in individual susceptibility to mold contamination, sampling results sampling may have limited application. However, sampling results can be used as a guide to determine the extent of an infestation and the effectiveness of the cleanup. Their interpretation is best left to the industrial hygienist or other environmental health or safety professional. Sampling for mold should be conducted by professionals with specific experience in designing mold-sampling protocols, sampling methods for microbial contaminants, and interpretation of results.
For additional information on air sampling, refer to the American Conference of Governmental Industrial Hygienists’ document, “Bioaerosols: Assessment and Control.” In addition, sampling and analysis should follow any other methods recommended by either OSHA, NIOSH, EPA, the American Industrial Hygiene Association, or other recognized professional guidelines. Types of samples can include: air samples, surface samples, bulk samples, and water samples from condensate drain pans or cooling towers. Microscopic identification of the spores/ colonies requires considerable expertise.
These services are not routinely available from commercial laboratories. Documented quality control in the laboratories used for analysis of the bulk, surface, and other air samples is necessary. The American Industrial Hygiene Association offers accreditation to microbial laboratories (Environmental Microbiology Laboratory Accreditation Program (EMLAP)). Accredited laboratories must participate in quarterly proficiency testing (Environmental Microbiology Proficiency Analytical Testing Program (EMPAT)).
Remediation Equipment
There are various types of equipment useful in mold assessment and remediation. Some of the more common items include:
Moisture Meters
Moisture meters measure/monitor moisture levels in building materials, and may be helpful for measuring the moisture content in a variety of building materials following water damage. They also can be used to monitor the progress of drying damaged materials. These direct reading devices have a thin probe that is inserted into the material to be tested or pressed directly against the surface of the material. Moisture meters can be used on materials such as carpet, wallboard, wood, brick, and concrete.
Humidity Gauges or Meters
Humidity meters can be used to monitor indoor humidity. Inexpensive (less than $50) models that monitor both temperature and humidity are available.
Humidistat
A humidistat is a control device that can be connected to an HVAC system and adjusted so that if the humidity level rises above a set point, the HVAC system will automatically turn on and reduce the humidity below the established point.
Boroscope
A boroscope is a hand-held tool that allows users to see potential mold problems inside walls, ceiling plenums, crawl spaces, and other tight areas. It consists of a video camera on the end of a flexible “snake.” No major drilling or cutting of dry wall is required.
HVAC System Filter
High-quality filters must be used in a HVAC system during remediation because conventional HVAC filters are typically not effective in filtering particles the size of mold spores. Consult an engineer for the appropriate filter efficiency for your specific HVAC system, and consider upgrading your filters if necessary. A filter with a minimum efficiency of 50 to 60% or a rating of MERV 8, as determined by Test Standard 52.2 of the American Society of Heating, Refrigerating and Air-Conditioning Engineers, may be appropriate. Remember to change filters as appropriate, especially following any remediation activities. Remove filters in a manner that minimizes the reentry of mold and other toxic substances into the workplace. Under certain circumstances, it may be necessary to wear appropriate PPE while performing this task.
How Do You Know When You Have Finished Remediation/Cleanup?
You must have identified and completely corrected the source of the water or moisture problem.
Mold removal should be complete. Visible mold, mold-damaged materials, and moldy odors should no longer be present.
Sampling, if conducted, should show that the level and types of mold and mold spores inside the building are similar to those found outside.
You should revisit the site(s) after remediation, and it should show no signs of moldy or musty odors, water damage, or mold growth.
Conclusion
After correcting water or moisture infiltration, the prompt removal of contaminated material and structural repair is the primary response to mold contamination in buildings. In all situations, the underlying cause of water accumulation must be rectified or the mold growth will reoccur. Emphasis should be placed on preventing contamination through proper building and HVAC system maintenance and prompt repair of water damaged areas.
Effective communication with building occupants is an essential component of all large-scale remediation efforts. The building owner, management, and/or employer should notify occupants in the affected area(s) of the presence of mold. Notification should include a description of the remedial measures to be taken and a timetable for completion. Group meetings held before and after remediation with full disclosure of plans and results can be an effective communication mechanism. Individuals with persistent health problems that appear to be related to mold exposure should see their physicians for a referral to practitioners who are trained in occupational/environmental medicine or related specialties and are knowledgeable about these types of exposures.
