How Do I Use the Extinguisher If I Decide to Fight the Fire?
Pull: The pin: Some extinguishers require releasing a lock latch, pressing a puncture lever, or taking another first step.
Aim: Low: Point the extinguisher nozzle (or its horn or hose) at the base of the fire.
Squeeze: The handle: This releases the extinguishing agent.
Sweep: From side to side: Keep the extinguisher aimed at the base of the fire and sweep back and forth until it appears to be out. Watch the fire area. If the fire breaks out again, repeat the process.
