When charging a supply line at a hydrant, the fire fighter should __________.

When charging a supply line at a hydrant, it is critical for the firefighter to avoid standing between the hose line and the hydrant. This position can be extremely dangerous because once the water is released from the hydrant, the high pressure can cause the hose to move unexpectedly, potentially leading to injury. By staying clear of this area, firefighters can prevent being struck by the hose or experiencing other hazards related to the sudden force of the water.

Standing directly behind the hydrant could expose a firefighter to sudden water pressure when the valve is opened. Using both hands on the valve is important for control but does not address positioning in relation to the potential hazards of the hose. Maintaining eye contact with the driver/operator is helpful for communication but does not ensure safety regarding the flow of water. Therefore, the correct approach emphasizes safety by minimizing risk and ensuring that the firefighter is in a secure location while the supply line is being charged.
