What does the term "mop-up" refer to in firefighting?

The term "mop-up" in firefighting specifically refers to the process of securing the fire area after initial suppression efforts have taken place. This phase involves extinguishing any remaining hot spots, checking for smoldering materials, and ensuring that the fire does not reignite or spread. Effective mop-up is crucial for preventing flare-ups and maintaining safety in the area. Firefighters typically use hand tools, hoses, and other equipment to accomplish this task. It ensures that the area is safe for both personnel and the public, and it is an essential component of the overall firefighting strategy.

The other options relate to different aspects of firefighting and incident management, but do not accurately describe "mop-up." Starting new fires for training is unrelated to the direct suppression and security of an existing fire, summoning additional resources pertains to requesting further support during active firefighting, and documenting incidents refers to the recording of events and data post-incident, which is not part of the mop-up process.
