Super Storm Sandy Cleanups, Educate Yourself!

Hope everyone survived Sandy, the Nor'easter, and Thanksgiving!  Since Sandy we've been getting a lot of phone calls on handling all the different issues related to the super storm.  Questions regarding mold, asbestos, lead, and the use of biocides.  In order to assist with providing information on these issues their are several videos we have worked with IAQTV and Cochrane & Associates to provide some basic information on these issues.  The most recent video is based on what it takes to dry out an area based on the type of water that has infiltrated the area. See our video "Dry Out Hazards Following a Flood or Water Incursion" at: http://www.youtube.com/watch?v=64u9RNPKbtI&feature=em-uploademail

Superstorm Sandy Uprooted/Broke Many Trees Causing Severe Power Outages
After super storm Sandy building materials were probably disturbed and may have become damaged requiring removal or replacing.  Anytime you are dealing with building materials, you are probably going to have to deal with asbestos and/or lead.  Asbestos was typically used as an insulator, however, the material can also be found in floor tiles & mastics, plaster-on-lathe, ceiling tiles, siding shingles, window caulking, & roofing shingles (remember asbestos is not banned and can be found in certain new building materials).  For more information about asbestos threats in the home, see our video "Asbestos Threats in the Home" at:  http://www.prlog.org/10943541-asbestos-threats-in-the-home-revealed-in-new-video.html.  In New York State workers and companies that disturb or handle asbestos are required to be certified and licensed.  In addition, projects that disturb/handle asbestos in quantities greater than 10 square feet and/or 25 linear feet require asbestos air/project monitoring to determine if the project has been completed properly.  This air/project monitoring firm and individuals must also be licensed and certified and are required to be completely independent of the contractor (must be hired by the owner of the facility/residence) handling/disturbing the asbestos.
Lead was usually used in paint and also in window caulking.  For more information about lead in the home, see our video "Lead Hazards in the Home" at:  http://www.youtube.com/watch?v=z5UnRr0tj88.  The Environmental Protection Agency (EPA) under the Renovation, Repair, and Painting Rules (RRP) requires renovation, remodeling, and painting contractors must be certified in lead paint work procedures.  Visit EPA's website regarding how this rule applies for post-disaster renovations: http://epa.gov/lead/rrp/emergency.html  . 
With significant water infiltration on the shore areas, if these areas were allowed to stay damp for longer than 48-hours, then mold had the opportunity to grow.  The extent of mold growth and type of mold would be based on the type of water (black, grey, or white) and the amount of water.  To learn more about mold see our video "Health Effects of Mold Exposure" at:  http://www.youtube.com/watch?v=DbKoonHwvHM  For those who have had sewage water (known as black water) infiltration into their residence/facility should see our video "Sewage Contamination Dangers" at:  http://www.youtube.com/watch?v=V4XORptvcX8.  When looking for contractors to handle mold, unlike asbestos and lead there is no federal, state or local licensing.  However, you should make sure the contractor you hire has workers who are industry certified in mold remediation from the American Council for Accredited Certifications (ACAC).  Find the ACAC and those certified individuals at:  http://acac.org/.
When it comes to biocides it is very important to be cautious, when using bleach or other stronger biocides.  Biocides (meaning kills life) are designed to kill and must be registered (licensed) with EPA under the Federal Insecticide, Fungicide, Rodenticide Act (FIFRA).  The label is the law for these products.  Meaning the chemical must be used in accordance with the label.  The label must list all the limitations and where the product is allowed to be used.  For information about biocides visit EPA's website on FIFRA at:  http://www.epa.gov/lawsregs/laws/fifra.html and visit the following website for registered disinfectants: http://www.epa.gov/oppad001/chemregindex.htm  Remember EPA does NOT recommend the use of biocides for mold cleanups, visit EPA's website regarding using bleach for mold cleanups at http://iaq.supportportal.com/link/portal/23002/23007/Article/20290/Should-I-use-bleach-to-clean-up-mold .  See EPA's website and the EPA manual "A Brief Guide to Mold, Moisture, and Your Home" at: http://www.epa.gov/mold/moldguide.html.
To quote a Long Island retailer, "An educated consumer is our best customer.". In the case of environmental hazards it is the same.  Educate yourself on the hazards and you can better avoid hazards, unnecessary expenses & services, and headaches.  Please be safe and take care!

Prevent Mold From Growing During Rainfalls


In the last few months we have seen significant rainfall in the northeast. This rainfall is causing some minor problems with our plants and grass (how many times are we going to have to cut the grass this year?). These problems are a nuisance; however they are easily resolved with very little expense. When this rainfall enters our homes or business establishments, these problems can lead to some significant costs for repairs and if we ignore the problems then mold can grow. We have seen previously several articles, when the rainfall was previously significant and it intruded into buildings, regarding tenants or occupants having to move or close their businesses because of the water damage to property or equipment. To prevent this from happening in this current period of significant rainfall, remember the following tips from the Environmental Protection Agency (EPA):
  • Fix all leaks in the building envelope (i.e., roof leaks, foundation cracks)
  • Look for condensation and wet spots, fix the cause and dry these areas quickly
  • Prevent condensation by either reducing surface temperature (by insulating or increasing air circulation) or reducing moisture level in air. Reduce moisture levels by either increasing ventilation (if outside air is cold and dry) or dehumidify (if outdoor air is warm and humid).
  • Keep heating, ventilation, and air conditioning (HVAC) drip pans clean, flowing properly, and unobstructed.
  • Clean and dry wet or damp spots within 48 hours
  • Do not let foundations stay wet. Provide drainage and slope the ground away from the foundation.
  • Any water damaged materials that remain wet for more than 48 hours should be disposed of or hire a water restoration expert to handle the situation.
  • If you have significant water damage, contact your insurance company immediately.
  • Many insurance companies exclude mold growth in their policies. The sooner you notify the insurance company of your claim, excluding your claim becomes less of likely.

Keeping Your Family Safe Program - Talks about Mold Sampling


Monday, January 19, 2009, we had the pleasure of interviewing Dr. Harriet Burge, formerly from Harvard’s School of Public Health and the current Director of Aerobiology at Environmental Microbiology Laboratories for our internet radio program “Keeping Your Family Safe” (find it at http://www.voiceamerica.com/ on the Green Talk Network). In our program, we discussed the mold (microbial) sampling. We covered the following points:

  • General discussion on fungi and molds.
  • The most common health effect of molds is an allergic reaction.
  • Other health effects include infections and fungal sinusitis. Health effects of mycotoxins are controversial.
  • Fungi need water and food to grow. When fungi grow in places we do not want them we call them molds. Fungi and molds spread by spores.
  • Three types of sampling (bulk, surface, and air).
  • There are no standards.
  • Each method has advantages, but air is the only way to document exposure.
  • Viable (culturable) versus nonviable (particulate).
  • Culturable sampling are strongly biased.
  • Particulate sampling can be a very powerful tool.
  • There are new methods but not commonly used yet.
  • A number of samples are needed to get representative results and document exposure

This Monday, January 26, 2009, we will be interviewing Mr. Charles Wiles the executive director of the American Indoor Air Quality Council regarding certification in the indoor air quality and mold industry.
