If there is a sudden blockage of air flow or complete loss of system air supply, what should you do?

• A. Seek assistance from team
• B. Try to repair the system on site
• C. Continue working slowly
• D. Leave the contaminated area immediately

Answer: (D)

When the SCBA air flow is suddenly blocked or the supply is lost, your first action must be to get out of the contaminated area into breathable air immediately. This is an emergency situation where continuing work or trying to repair the system would quickly put you at risk of hypoxia or exposure to the hazard. Stop what you’re doing, move toward the nearest safe exit or fresh air, and communicate your status to teammates or incident command. If you can’t reach safety right away, activate your PASS device to signal distress while you navigate to an exit. Seeking assistance is appropriate once you’re in a safe area, but it does not replace the immediate need to remove yourself from danger.
