What is the first action when an accidental asbestos fiber release occurs?

• A. Isolate the area and evacuate
• B. Report the incident to the supervisor
• C. Stop work immediately
• D. Perform cleanup using wet methods

Answer: (C)

The immediate priority in an accidental asbestos fiber release is to stop work immediately to prevent further disturbance and exposure. Disturbing asbestos-containing material can kick fibers into the air, so halting the activity cuts off the main source of release and buys time to manage the situation safely. Once the work has stopped, the area should be isolated and access controlled so others aren’t exposed or spread fibers, and the supervisor should be informed to initiate proper containment and investigation. Cleanup with wet methods and other remediation steps are important, but they should be carried out only by trained personnel after the area is stabilized and appropriate controls are in place. This sequence protects workers from unnecessary exposure and helps ensure the incident is handled correctly.
