Handling Vermiculite Insulation for Building Inspections and Air Monitoring

The Environmental Protection Agency’s (EPA) recent decision to declare a public health emergency at the Libby asbestos site in Montana has brought vermiculite insulation back in front of people’s minds. EPA’s announcement did not mention what to do if you have this type of insulation. Remember there are some major issues with this type of insulation. First it seems the vermiculite can actually hide the tremolite asbestos from detection, leading to false results. When individuals disturb the vermiculite insulation it can release tremolite asbestos at significant levels into the air.

Because of these technical issues EPA and the Agency for Toxic Substances and Disease Registry (ATSDR) both recommend that if you find vermiculite insulation that you not test it for asbestos. Instead they recommend you assume the vermiculite insulation is from Libby and assume it contains asbestos. The Libby mine was the source for over 70% of the vermiculite sold in the United States from 1919 to 1990. EPA and ATSDR feel that the technical issues involving vermiculite sampling can complicate testing for the presence of asbestos fibers and interpreting the risk from exposure. This is a significant statement and interesting that it has not been published more.

Based on this, as an asbestos inspector, environmental inspector, home inspector, and/or air quality consultant, you must evaluate vermiculite insulation as containing asbestos (without sampling). In addition, you must inform the owner that sampling the material will not provide a definitive answer. EPA and ATSDR both recommend that professional asbestos abatement contractors handle any disturbance of the vermiculite insulation. The best practice for air monitoring and analysis of these projects, for the protection of the public, is Transmission Electron Microscopy. As these issues are not well known, even in the asbestos industry, it is important for owners to be aware of this potential problem and take the precautions necessary.

Public Health Emergency Declared in Libby, Montana

As with everyone else who is aware of this tragedy we applaud the Environmental Protection Agency’s decision on June 17, 2009 to declare that a public health emergency exits at the Libby asbestos site (vermiculite mine contaminated with tremolite asbestos) in northwest Montana. The New York Times, Newsday and other newspapers covered this press release and the Asbestos Disease Awareness Organization issued their own release covering this issue. The documentary film “Dust to Dust” directed by Michael Brown told the Libby story (we have watched this film in some of our classes). As the press release indicates, this announcement, which is long overdue, will provide funds for the continued clean-up of the contaminated areas in the towns of Libby and Troy. In addition, the Department of Health and Human Services will provide grant money to provide medical care for the area residents impacted by the contamination.

Keeping Your Family Safe - Healthy Homes

Monday, March 30, 2009, we had the pleasure of interviewing Dr. Pam Meyer of the Centers for Disease Control and Prevention (CDC) and Dr. Peter Ashley of the U. S. Department of Housing Urban Development (HUD) for our internet radio program “Keeping Your Family Safe” (find it at http://www.voiceamerica.com/ on the Green Talk Network). Our discussion was about the Healthy Homes Program. CDC is the nation’s primary public health agency and is part of the U.S. Department of Health and Human Services. CDC provides information to help the public make informed decisions and take actions to promote health and wellbeing. HUD makes affordable housing available to low income households, and supports community development and home ownership. Dr. Meyer and Dr. Ashley discussed how CDC and HUD were working together to promote Healthy Homes. Healthy Homes is a century-old concept that promotes safe, decent, and sanitary housing as a means for preventing disease and injury. In our program, we covered the following points:

• CDC and HUD support Healthy Homes by providing grants to fund research on Healthy Homes
• Increasing amount of scientific evidence linking health outcomes, such as asthma and unintentional injuries, to substandard housing
• CDC has a few cooperative agreements with state or local health departments to take a healthy homes approach
• HUD’s focus is not health research so they rely heavily on reviews, such as the National Academy of Sciences
• HUD recently has funded some research, for example Cuyahoga County Grant – home interventions to address mold/moisture problems resulted in significant improvements in the health of asthmatic children & Seattle Grant – studied new green built public housing units on the health of asthmatic children after they moved into the units (breathe easy homes)
• Discussion on research on allergies & asthma in regards to triggers, unintentional injuries, and poisonings

This was our final show for this period, we hope those of you who listened enjoyed the programs.

Keeping Your Family Safe - Dangers in the Basement

Monday, March 9, 2009, we had the pleasure of interviewing Mr. Bob Krell, President and Certified Indoor Environment Consultant for IAQ Technologies for our internet radio program “Keeping Your Family Safe” (find it at www.voiceamerica.com on the Green Talk Network). IAQ Technologies is an indoor environmental and building performance firm offering consulting, mitigation, and training services to a variety of clients throughout the country. Mr. Krell discussed various dangers we can find in basements that homeowners should be aware of and some ways to protect themselves. In our program, we covered the following points:

• Asbestos
• Radon
• Mold and Bacteria (Differences between black, grey, and clear water)
• Better Building Materials and Dehumidification to help prevent mold growth

This Monday, March 16, 2009, we will be discussing “Audubon at Home” with Aaron Virgin Executive Director of the Theodore Roosevelt Sanctuary and Audubon Center.

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.

Keeping Your Family Safe Program - Talks about Asbestos

Monday, Jan. 12, 2009, we had the pleasure of interviewing Linda Reinstein, the Executive Director and co-founder of the Asbestos Disease Awareness Organization for our internet radio program “Keeping Your Family Safe" (see below for the website information). In our program, we discussed the dangers of asbestos and asbestos-containing materials. We covered the following points:

• More than 10,000 Americans die of asbestos caused diseases every year.
• India has the highest exposure to asbestos and is the second largest importer of asbestos.
• Worker exposure also affects family members at home.
• Asbestos – there is no ban, and has been listed as a human carcinogen for over 30 years.
• The United States Environmental Protection Agency (EPA), the World Health Organization, and the International Labor Organization, all believe that there is no safe exposure level to asbestos and that asbestos kills.
• Asbestos has a long legacy because it is virtually indestructible.
• Friable is a measure of asbestos’ ability to become airborne. Though an asbestos-containing building material may not be friable, that material can still release asbestos if homeowners work on it.
• Over 3,000 products contain asbestos.
• Once asbestos enters the body, especially the lungs, it is difficult to get the asbestos out of the body.
• Health effects – non-malignant and malignant diseases. Asbestosis, mesothelioma, lung, gastro-intestinal, and kidney cancers, pleural thickening, and pleural plaques all are life threatening. All reduce the ability to breathe.
• Construction and building trades are typically exposed to asbestos.

Keeping Your Family Safe Program - Talks about Lead Paint

Happy New Year everyone. On Monday, January 5, 2009 I had the pleasure of interviewing Dr. Eileen Franko, the Director of the Bureau of Occupational Health within the New York State Department of Health on my radio program "Keeping Your Family Safe." The interview was on lead paint hazards and we discussed the use of lead in paint, the health effects, the laws and regulations, and proper procedures for working with lead paint hazards.
During our interview Dr. Franko and I discussed:

• In 1978, the Consumer Product Safety Commission reduced the amount of allowable lead in homeowner, interior, exterior, furniture, and toy paints and varnishes to less than 0.06%.
• However, prior to 1978 paints and varnishes had lead added to them while paints and varnishes prior to 1950s could be up to 50% lead.
• Intact lead paint is not a hazard.
• Any activity that generates particles, dust, or debris can cause lead exposure.
• Lead exposure typically happens by ingesting (through contaminating food or drinks, and hand to mouth exposure primarily for children) or inhalation (breathing in the dust or particles).
• Lead exposure health effects for children include brain damage,nerve damage, reduced intelligence (IQ), learning problems, hearing problems, behavorial issues, and death. 2002 was the last death of a child from lead poisoning.
• Lead exposure health effects foradults include infertility, high blood pressure, teratogen effects, and lead can cross the placenta causing poisoning of the unborn child.
• Any blood lead is too much lead and the only way to determine the amount of lead in the body is through a blood test. Over 10 micrograms of lead per deciliter of blood is considered elevated for kids and adults. For workers working with lead the Occupational Safety and Health Administration (OSHA) has a construction industry standard of 50 micrograms of lead per deciliter of blood.
• The Environmental Protection Agency (EPA), OSHA, and Housing and Urban Development (HUD) have regulations on handling lead based coatings.
• Before performing work on buildings built prior to 1978, owners, occupants, and tenants should consider lead paint. Those considerations should include:
  - minimizing dust utilizing wet methods and practices to limit the creation of dust.
  - dust collection with vacuums with HEPA filtering.
  - the use of protective equipment such as respirators with HEPA filters, disposable suits and gloves.
  - use plastic to protect areas where dust is unwanted or to limit dust into areas where work is being performed.
  - remove furniture and other items to limit what is contaminated with lead dust.

Our next program will be Monday, February 12, 2009 at 2 PM eastern time. We will be interviewing Mrs. Linda Reinstein, the Executive Director of the Asbestos Disease Awareness Organization, discussing the asbestos hazard. We hope you will join us.
