What should the AHJ establish to direct firefighter response during air monitoring?

• A. A policy for transporting detectors off-site
• B. A schedule for shift changes based on alarms
• C. Action levels describing how firefighters should respond to high- or low-level alarms
• D. A fixed response to all alarm levels

Answer: (C)

When monitoring air, the essential idea is to set action levels that translate sensor readings into specific, predefined firefighter actions. By defining what to do at low readings versus high readings, the incident command can adjust protective equipment, exposure time, and tasks in a graded, real-time way. This approach keeps responders safer and more effective, because actions scale with the level of danger rather than applying the same response to all alarms.

Other options miss the mark because simply moving detectors off-site doesn’t address in-field safety, scheduling shift changes based on alarms doesn’t directly govern exposure protection, and a fixed response to all alarm levels ignores how risks change as readings rise or fall.
