If containment breach is suspected during asbestos removal, which action is required?

• A. Locate and repair containment breach
• B. Ignore and continue removal
• C. Continue removal with increased ventilation
• D. Call for a new work crew to finish the job

Answer: (A)

A containment breach compromises the barrier that keeps asbestos fibers from spreading, so the immediate priority is to locate and repair the breach to restore the containment and negative pressure. Fixing the breach prevents further fiber release and protects workers and nearby areas. After repair, re-establish the containment, verify proper negative pressure, and conduct appropriate air monitoring before resuming work. Ignoring the breach or trying to compensate with more ventilation would likely spread fibers, and simply bringing in a new crew does not address the hazard at hand.
