ASBESTOS SAMPLING AND TESTING
Our Asbestos Testing/Inspection Services:
We test for asbestos in accordance with Ontario Regulation 278/05, which means a minimum of three bulk samples or two air samples analysed by a certified laboratory per homogenous material/area. This makes our reports both certified and legal. We are fully certified, insured and WSIB. We perform work for many property management companies, contractors, private homeowners and schools. Call or contact us for an estimate, 416.419.8546.
Asbestos Bulk Sampling:
Common areas of concern for asbestos in homes includes asbestos in tile flooring, asbestos in popcorn ceiling, vermiculite asbestos insulation, asbestos pipe wrap, asbestos duct wrap, asbestos drywall joint compound and asbestos in textured plaster.
Depending on the outcome of the testing, we will provide you with recommendations. You will receive two reports (laboratory report and A Canadian Home Inspection. report), via email; and you are welcome to consult with us regarding asbestos safe work practices and asbestos handling. We will determine if no asbestos is present (ND – None Detected), or alternatively if asbestos is present, the quantity and the type i.e. chrysotile abets – 5%. Anything over 0.5% is considered unsafe, and should be handled accordingly. We can also perform an Asbestos Air Sample if the Asbestos Bulk Sample does contain asbestos.
Asbestos Air Sampling:
PCM asbestos air sampling can be performed to identify airborne asbestos and other fibres. Such tests prove to be very useful as clearance samples after asbestos abatement has been performed or in instances when you may be concerns that asbestos has been disturbed i.e. moving into a newly renovated house that is older than 1980.
TEM asbestos air samples provide the actual quantity of asbestos fibres specifically, however, PCM and TEM refer to laboratory analysis methods, one being more specific and expensive than the other. Ontario regulation 278/05 generally allows for PCM air sampling (see below) as a reasonable gage of whether or not the air is safe, however, TEM air sampling can be performed.
PCM Air Sampling (to detect asbestos and other fibres):
We will take a minimum of two air samples in the area(s) of concern (number of samples depends on square footage of affected area.) You will receive two reports, via email, in four business days, namely the laboratory report and The Healthy Abode Inc. report. We will determine the quantity of airborne fibres. According to Ontario Regulation 278/05 Sec. 18(5), in order to “pass” this test, every air sample collected much have a concentration of fibres that does not exceed 0.01 fibres per cubic centimetre of air (<0.01 fibres/cc.) The air samples will run concurrently for 160 minutes. Each air sample, in accordance to Ontario Regulation, we collect 2,400 litres of air. Fans will be run to agitate the air while asbestos sampling, as per Ontario Regulation 278/05 requirement.
Sources of Asbestos
Occupational – The risks are greatest for workers in industries with produce and use asbestos, such as mining and milling. Today’s strict standards, however, limit workers’ exposure and the ban of most uses of amphibole asbestos have reduced the risk.
During renovations and repairs to older buildings, construction workers, tradespeople and other building maintenance workers may be exposed to very high concentrations of asbestos fibers.
Environmental – Negligible levels of asbestos fibres are found in the soil, water and air, both naturally and from man-made sources. Asbestos concentrations in the air in rural areas are about ten times lower than those in larger cities, which are about 1,000 times lower than levels accepted in today’s asbestos-related jobs. With such low exposure, environmental risks are negligible.
Buildings & Homes – Because it is a valuable reinforcing, insulating and fire-proofing material, asbestos was used widely in construction materials such as insulation board, asbestos cement, and floor and ceiling tiles. These products are very dense and do not release significant amounts of fibres under normal use. However, fibres may be release if these products are cut or damaged.
Asbestos fibre concentrations in the air in buildings are usually about the same as in the air outside, and are not a significant risk. However, levels may be higher if friable asbestos materials are disturbed. One of the main problems with asbestos came from sprayed or “friable” (easily broken up) amphibole asbestos used in buildings until the 1970s.
There is also concern about vermiculite insulation which may contain small amounts of amphibole asbestos, principally tremolite or actinolite. These amphibole fibres may cause health risks if disturbed. However, there is currently no evidence of risk to your health if the insulation is sealed behind wallboards and floorboards, isolated in the attic or otherwise kept from exposure to the home or interior environment, states Health Canada, April, 2011.
