What does the "buddy system" refer to in firefighting?

The "buddy system" in firefighting refers to a practice where firefighters work in pairs or teams of at least two members who maintain constant contact with each other while on the scene. This system is crucial for safety, particularly in hazardous environments like those encountered during fires. Having a partner ensures that each firefighter has someone to rely on, should an emergency situation arise, such as loss of consciousness, disorientation, or injury. It also assists in accountability, as each member can check on the others' well-being and status, which is essential for effective emergency response.

In contrast, the other options do not accurately encompass the meaning of the "buddy system." A method for training new recruits focuses more on educational practices rather than the operational safety aspect that the buddy system emphasizes. Rotating firefighters during a shift pertains to workload management and staffing rather than the direct safety measures taken while actively responding to emergencies. Lastly, techniques for extinguishing fires efficiently are strategies specific to firefighting operations that do not involve the buddy system's safety-oriented practice.
