Prior to entering a fire area with a charged hose line, the nozzle operator should first

• A. test water at the nozzle
• B. advance rapidly into the area
• C. call for backup
• D. bleed air from the line

Answer: (D)

Bleeding air from the line is essential because a charged hose often carries air pockets between the pump and the nozzle. If you enter with air in the line, the moment you open the nozzle the air can cause a delayed water delivery, pulsation, or a kick in the stream, making it hard to control and slowing the attack. Purging the line first clears that air, filling the line with water so the nozzle can deliver a steady, controllable stream right away as you advance. This step also helps verify the line is truly ready for use. Other options don’t prepare the line for immediate, effective water application: testing water at the nozzle can be unreliable with air present, advancing rapidly without a ready stream is unsafe, and calling for backup, while important, doesn’t address making the line ready for action.
