Which action helps prevent asbestos fibers from becoming airborne during cleanup?

• A. Use proper wet methods during cleanup
• B. Dry sweeping to speed cleanup
• C. Use high-velocity fans around the area
• D. Use vacuums without HEPA filters

Answer: (A)

Keeping asbestos fibers from becoming airborne hinges on suppressing dust at the source. Wetting the material before and during cleanup binds the fibers and keeps dust from drifting into the air, allowing debris to be cleaned up and contained in sealed bags or approved waste containers. This approach significantly reduces the likelihood that fibers will be released into the workspace and inhaled.

Dry sweeping would disrupt dust and release fibers into the air. Using high-velocity fans can stir up and spread any trapped fibers instead of containing them. Vacuuming with a non-HEPA filter may re-aerosolize fibers and release them back into the room or exhaust them outside. Therefore, using proper wet methods during cleanup is the best way to minimize airborne asbestos and protect workers.
