Fire Pump Run Practice Test

Before moving a deck gun into a structure fire, the primary safety step is to verify that no personnel are in the path of the discharge. The high-velocity water stream can injure firefighters or knock them off balance, and anything in its line of fire can be struck unexpectedly as you adjust aim or reposition the gun. Establishing that the stream will not cross anyone’s position directly protects crews in the vicinity and prevents serious injuries. While keeping the path clear, selecting the right nozzle setting and establishing a safe operating range are important for effectiveness and control, they don’t address the immediate hazard of someone standing in the line of fire. If someone were in the stream’s path, the other precautions wouldn’t prevent an injury until they’re moved out of the way.
