An officer and a firefighter on a handline enter a structure fire and begin extinguishment when without warning the floor gives way and they fall into the basement. A Mayday is transmitted, and a firefighter assist search team (FAST) is quickly deployed. Mutual aid, or additional alarms, is dispatched as operations now focus on assisting the FAST by controlling the fire and getting the trapped firefighters removed to safety. The problem is compounded as rescue crews have a difficult time gaining access to the trapped firefighters. The area around the opening is unstable. Stairs are burned away or cannot easily be found. Self-rescue is also a problem because of injuries or a confusing layout. Low-air alarms on the trapped firefighters begin to sound as the rescue operation continues.
大多数消防员读过或听过或甚至可能have been involved in a situation like this. A firefighter is trapped, needs help, and cannot self-rescue. This incident could have occurred in a variety of ways-a fall through an opening, a collapse that prevents an exit, or an obstacle that entangles or pins. The trapped firefighter has few options other than transmitting a Mayday message and activating the PASS alarm. In a situation like this, air management is critical. The trapped firefighter must remain calm and try to conserve air while waiting for help.
Managing the air supply when using an SCBA should not be anything new to a firefighter. To be able to manage air when faced with a situation like that described above, you need to practice and drill. Described below is an air management drill that is easy to set up and will build confidence in managing SCBA air.
