Asbestos Contractor/Supervisor Practice Exam

Which statement accurately describes the proper use of disposable respirators on asbestos abatement projects?

1. They can be used interchangeably with reusable respirators

2. They are acceptable for use when working with non-friable asbestos

3. The OSHA standard prohibits their use on asbestos abatement projects

4. They must be equipped with filters that last indefinitely

The correct answer is: The OSHA standard prohibits their use on asbestos abatement projects

The statement that accurately describes the proper use of disposable respirators on asbestos abatement projects is that the OSHA standard prohibits their use on such projects. This standard is based on the understanding that disposable respirators do not provide adequate protection in environments where asbestos exposure is a concern. Asbestos fibers can be very hazardous, and working with them typically requires higher levels of protection than what disposable respirators offer. In asbestos abatement projects, the primary focus is on ensuring the safety of workers, which necessitates the use of respirators specifically designed for such high-risk environments. These are usually full-face or half-mask respirators that can accommodate replaceable filters capable of removing harmful asbestos fibers. The regimen established by OSHA promotes the use of these specialized respirators to ensure the highest level of protection against inhalation of asbestos. Additionally, while reusable respirators might provide sufficient protection, disposable ones are not suited for environments where asbestos is present due to their limited filtration capabilities. OSHA emphasizes the need for proper respiratory protection to mitigate the risks associated with asbestos exposure effectively.
