What is the primary use of HEPA vacuums in asbestos work?

In asbestos work, HEPA (High-Efficiency Particulate Air) vacuums play a crucial role in maintaining safety and containment during the abatement process. Their primary function is to effectively clean surfaces after asbestos removal activities have been performed. HEPA vacuums are designed to trap 99.97% of particles that are 0.3 microns in diameter, which includes asbestos fibers. This level of filtration ensures that any residual asbestos dust or fibers that may remain on surfaces are captured and not released back into the environment.

While the other options might appear relevant, they do not accurately represent the primary function of HEPA vacuums. For instance, disposing of toxic materials, inspecting containment areas, or removing air from enclosed spaces do not align with the specific purpose of HEPA vacuums in asbestos remediation. Instead, the emphasis is on their effective cleaning capability to ensure a safe and compliant work environment after abatement activities are concluded.
