And what is the third action in that protocol?

• A. Leave contaminated area immediately
• B. Return to work
• C. Check that cylinder is fully opened
• D. Fully open purge valve

Answer: (A)

In hazardous environments, the top priority is personal safety and minimizing exposure time. The third action in this protocol is to leave the contaminated area immediately. Exiting right away stops further inhalation or contact with the hazard, which is why this step takes precedence over anything you might try to do while still inside. The other options aren’t appropriate as the third action because they either involve continuing to operate inside the hazard zone or relate to equipment functions rather than addressing the immediate danger. Returning to work while still exposed would keep you at risk. Checking that the cylinder is fully opened or fully opening the purge valve are equipment-related steps that belong before or after exposure, not as the immediate response to a contamination risk. After exiting, you can proceed with proper decontamination, health checks, and any necessary equipment maintenance before re-entering.
