Which of the following describes the role of hose lines during rescue operations?

The role of hose lines during rescue operations primarily centers around controlling access and protecting exit routes. In the chaotic environment of a fire or rescue situation, hose lines can be strategically placed to create safe pathways for rescuers to move towards victims while also ensuring that the exit routes remain protected from the advancing fire or hazardous conditions. This allows the fire department personnel to effectively coordinate the rescue efforts while minimizing the risk of becoming trapped or disoriented.

Additionally, hose lines can serve as a means of marking safe routes for people evacuating a structure, enhancing their safety as they exit. By establishing a controlled perimeter through which both rescuers and evacuees can navigate, the situation is managed more efficiently and effectively. Thus, option C accurately captures this essential function of hose lines during rescue operations.
