What should be done with debris after stopping work due to elevated ambient air counts outside containment?

• A. Cleanup all debris
• B. Leave debris in place
• C. Move debris to an outdoor area
• D. Dispose of debris without containment

Answer: (A)

Elevated ambient air counts outside containment mean asbestos fibers may have escaped the controlled area, so the priority is to remove any potential sources of release and treat debris as asbestos waste. Debris left in place can be disturbed and re-emit fibers, spreading contamination. Moving debris outdoors or disposing of it without proper containment risks distributing asbestos to new areas and violates waste-handling rules. Cleaning up all debris, bagging and sealing it as asbestos waste, and following decontamination and disposal procedures prevents further release and allows the area to be re-evaluated for clearance before work resumes.
