What does class II works refer to in asbestos removal activities?

Class II work in asbestos removal specifically pertains to activities that involve the removal of non-friable asbestos-containing materials (ACM). Non-friable materials are those that, when intact, do not release asbestos fibers into the air under normal conditions. Examples of non-friable materials include floor tiles, asphalt roofing, and transite pipes, which may become hazardous if they are damaged or disturbed.

The classification helps ensure that appropriate safety measures and regulations are followed during removal, as non-friable materials present different risks compared to friable materials, which can easily release asbestos fibers when disturbed. Therefore, understanding that Class II works focus on non-friable asbestos helps workers and regulators differentiate the necessary precautions and procedures to manage the specific risks associated with these materials effectively.

Other choices reflect activities that either involve different classifications or do not pertain directly to the scope defined for Class II work.
