What Does 1% Asbestos Mean in Ontario?
A material that contains less than 1% asbestos is considered to contain trace levels of
asbestos. However, the 1% level is not a risk-based limit, and the concentration of asbestos in a material does not necessarily correlate to
air exposure.
Here are some things to consider about
asbestos:
-
In Ontario, ACM is defined as material that contains 0.5% or more asbestos by dry weight.
-
No amount of asbestos is considered safe, and the more asbestos you are exposed to, the more likely you are to get an asbestos disease.
-
OSHA regulations for asbestos apply to worker exposure to asbestos fibers in the air. Some methods of compliance include:
- Using vacuum cleaners with HEPA filters
- Using wet methods or wetting agents during handling, mixing, removal, cutting,
application, and clean-up
- Promptly cleaning up and disposing of wastes and debris contaminated with asbestos in leak-tight containers
- Using vacuum cleaners with HEPA filters
