What should the rear member of a hose team do when following the order to back out?

When the rear member of a hose team is instructed to back out, the primary responsibility is to take up the slack hose. This means ensuring that the hose is managed properly as the team exits the area, which not only helps maintain a clear path but also prevents the hose from tripping or becoming tangled. Taking up the slack allows for a safer retreat, minimizing the risk of accidents that could occur if the hose is left loose or coiled erratically.

Properly managing the hose is critical during a fire response, as it ensures that the team can move quickly and effectively while remaining connected to their water source. If the hose is not taken in, it could impede the movement of team members or affect their ability to respond if they need to move back into the area quickly. Thus, this action of taking up the slack is essential for both safety and effectiveness in firefighting operations. Other actions suggested by the alternatives, while they may seem relevant, do not focus on the immediate task of maintaining an efficient retreat with the hose.
