How far should personnel stand apart on the handline?

The recommended distance personnel should stand apart on the handline is 10 ft. This spacing allows for effective communication and coordination among crew members while ensuring safety in the event of fire flare-ups or unexpected hazards. Maintaining this distance helps minimize the risk of injuries, such as burns or smoke inhalation, which could occur if individuals are too close together during an active firefighting operation. Additionally, the 10 ft spacing facilitates the movement of equipment and personnel without hindrance, promoting efficiency and safety during critical firefighting tasks.
