Which statement best describes the required response to elevated ambient air outside containment?

• A. Stop removal, mist air with amended water, cleanup debris, locate and repair containment breach
• B. Continue removal with added speed
• C. Seal the area and return later without action
• D. Increase ventilation and proceed without stopping

Answer: (A)

When ambient air outside containment is elevated, it signals that containment has been compromised and asbestos fibers may be escaping into the work area. The right course is to pause the removal work, dampen the area with amended water to suppress dust and fiber release, clean up debris to remove loose fibers, and locate and repair the containment breach before resuming. This sequence protects workers and prevents the spread of asbestos.

Continuing removal at increased speed would likely push fibers further into the surrounding area. Sealing the area and returning later without fixing the breach leaves the exposure risk unresolved. Increasing ventilation and proceeding without stopping can blow fibers outside containment, defeating the purpose of the containment controls.
