Asbestos Testing
Prior to the 1970's many types of building products and insulation materials used in homes contained asbestos. If you think asbestos may be in your home, don't panic! Usually the best thing is to leave asbestos material that is in good condition alone. Generally, material in good condition will not release asbestos fibers. There is no danger unless fibers are released and inhaled into the lungs. If asbestos material shows signs of wear or damage such as tearing, abrasion, or water damage, or it is exposed to hitting, rubbing, or extreme vibration or air flow you should have it repaired or removed by a professional.
Some home inspectors offer the service of taking samples of suspected material and sending them to a lab for analysis. Results can take up to a week.

Asbestos is a dangerous carcinogen. Asbestos exposure may cause mesothelioma and lung cancer. Asbestos poses the greatest danger when it becomes airborne. Demolishing, repairing, or just disturbing suspect materials may cause the asbestos fibers to dislodge and release into the air. The following are some of the common asbestos containing materials that might be found in your home: acoustic ceilng spray, floor tiles, linoleum, insulation, drywall/joint compound, exterior stucco, roofing, etc. Thus before you disturb any material you suspect might contain asbestos, it would be a good idea to have a sample of that material tested by a qualified laboratory. Our fully-accredited laboratory provides fast and confidential testing. You will get the test results in 24 hours, or in many cases the very same day we receive your sample
Abatement
Reducing exposure to asbestos by repairing damaged material will involve covering the material or sealing it. Sealing is commonly used for pipe, furnace, and boiler insulation. The sealing process either coats the material, reducing fiber release, or binds the fibers together. A covering can be used instead of sealant, also preventing the release of fibers. Both these methods are relatively cheap when compared with removal, but future removal may still be necessary. Another technology used in reducing exposure to asbestos is personal protective equipment. Respirators with HEPA filters should be worn when working with asbestos, in addition to other controls.
Removal is the most expensive method of dealing with asbestos, and it also has the greatest risk involved, due to the large number of fibers that may possibly released in removing it. The most common way to reduce asbestos emissions during renovation, demolition, cutting or stripping of asbestos material is to use a wetting agent throughout to keep asbestos from becoming airborne. It is important that the material is adequately wet to prevent release. There are different wetting techniques for different types of material. The material should be sealed in containers after removal. A HEPA filter vacuum is essential for cleaning. It is important to never use a vacuum without HEPA filter; it will just spread the asbestos. Portable air ventilation systems can be used to protect workers from asbestos. Enclosure equipment is often used when working on brakes, to separate the worker from asbestos; the wet method is also used for brakes.
Today's technology makes it possible to monitor for asbestos, keep asbestos exposure below permissible limits, and remove the hazard. It protects the health of many people who would otherwise be exposed.
