How to Use a Fire Extinguisher
When fighting a small fire, maintain an unobstructed exit route at your back and stand six to eight feet away from the fire. Follow PASS to properly use the fire extinguisher.
P is for PULL– Pull the pin, breaking the tamper seal
A is for AIM – Aim the nozzle or hose low at the base of the fire
S is for SQUEEZE – Squeeze the lever above the handle to expel the extinguisher agent. To stop, release the lever
S is for SWEEP – Sweep the nozzle or hose side to side at the base of the fire until the fire is put out
Continue to monitor the area. If the fire reignites repeat Aim —> Squeeze —> Sweep
