How can asbestos become a threat to my health? |
The popular use of asbestos has stopped because scientists discovered that asbestos is harmful. When materials containing asbestos are disturbed or damaged, small fibers get into the air. Inhaling airborne asbestos particles can cause lung disease and cancer.
How can asbestos be identified? |
People who frequently work with asbestos material -- such as plumbers, contractors, and heating specialists -- can sometimes correctly identify whether or not a material contains asbestos just by visual inspection; however, the only way to be sure is to have a sample of the suspect material analyzed by a certified laboratory. Do not rely on visual determinations.
Materials suspected of containing asbestos should be treated as if they do until reliable analysis proves otherwise. Laboratories that do this work are usually listed in the phone book yellow pages under "Asbestos Consulting & Testing" and "Laboratories- Analytical."
How should materials suspected of containing asbestos be "sampled?" |
Generally, it is recommended that homeowners leave the sampling of suspect material to certified asbestos contractors/companies. This is especially important if the proposed sampling material is insulation on a hot water boiler and/or piping system, which can be very hazardous. If homeowners decide to sample, it is very important that they do not release asbestos fibers into the air, onto themselves, or others during the sampling operation.
What documents are needed for disposal? |
Before asbestos-contaminated waste can be accepted for disposal in a landfill in King County, Washington, it must be accompanied by the following:
Because of the great health risks, the disposal of asbestos is regulated by federal, state, and local laws.
What is required for the routine removal of asbestos? |
Notification must be provided in advance by persons removing asbestos containing material to the Puget Sound Air Pollution Control Agency which enforces regulations concerning removal and disposal.
Asbestos containing waste material:
- must be wetted down during removal to reduce airborne emissions;
- once adequately wetted down, must be sealed in a leak proof container; the container must be dust-tight and at least 6 millimeters thick.
How should asbestos be removed and cleaned up in an emergency? |
Wet all debris for disposal thoroughly with water to avoid free floating asbestos particles.
- use a water hose with a nozzle for a fine, low-pressure spray or mist to wet the debris;
- mix water with wetting agents, if possible.
Debris contaminated with asbestos (or even suspected of contamination):
- should be stabilized by adequate wetting;
- covered with plastic until removed by a licensed, asbestos contractor.
Debris containing at least one percent (1%) asbestos must be disposed of in approved landfills. The Cedar Hills Regional Landfill and Rabanco Recycling Company are the only places in King County that accept asbestos waste.
