When should the firefighter at the hydrant charge the supply line?

• A. Upon arrival
• B. After water supply confirmed
• C. When signal is received
• D. Before leaving the hydrant

Answer: (D)

Charging the supply line at the hydrant before leaving ensures the line is pressurized and ready to deliver water the moment the attack team needs it. This reduces delays, keeps the fire flow continuous, and prevents a pause while waiting to establish water supply. Waiting until water supply is confirmed, or until a signal is received, introduces unnecessary hold-ups, and charging after arrival also wastes valuable time. By charging before leaving the hydrant, you guarantee a smooth, immediate start to the interior attack once the scene is reached.
