If air supply begins to flow freely into the face piece during use, what action should you take immediately?

• A. Fully open purge valve
• B. Partially close cylinder valve until the amount of air needed by user is met
• C. Leave contaminated area immediately
• D. Stand by and assess the situation

Answer: (C)

When air begins to flow freely into the face piece, it indicates a regulator or seal problem that could deliver unregulated air or contaminants to you. The immediate priority is to get to fresh air and safety, not to troubleshoot the equipment in a hazardous environment. Exiting the contaminated area right away minimizes your exposure risk and allows you to reassess the situation in a safe place. Purging, adjusting valves, or delaying action would not reduce the immediate danger and could leave you breathing contaminated air or without proper air supply. After you’re out in clean air, you can report the issue and have the equipment inspected and repaired.
