What are the actions of the Back Up?

• A. Get a 2nd extinguisher, PBE at least and any other equipment as required; if PBE if required, fit PBE and relieve fire fighting crew member; if required, assist with the flow of information between the fire fighter and the communicator
• B. Direct passengers
• C. Evacuate the area
• D. Stand by and observe

Answer: (A)

Back Up is about supporting the primary fire fighting crew with additional resources and effective communication, so suppression can continue safely and smoothly. The actions involve obtaining a second extinguisher and the Positive Pressure Breathing device (PBE) at minimum, plus any other gear needed for the situation. If a PBE is required, the Back Up fits it and takes over from the current firefighter, allowing the original crewmember to be relieved and replaced without breaking the operation. An important part of the role is also helping to maintain clear information flow between the firefighter and the communicator, acting as a bridge to relay updates, needs, and changes in the scene. This combination of extra equipment, relief capability, and clear communication keeps the firefighting effort coordinated and safer for everyone involved. Directing passengers, evacuating the area, or standing by to observe do not align with the Back Up’s primary responsibilities during active suppression, as those tasks are handled by other crew roles focused on passenger management and overall safety.
