There is a simple acronym to remember to operate most fire extinguishers - PASS. PASS stands for Pull, Aim, Squeeze and Sweep.
- Pull the pin at the top of the cylinder. Some units require the releasing of a lock latch or pressing a puncture lever.
- Aim the nozzle at the base of the fire.
- Squeeze or press the handle.
- Sweep the contents from side to side at the base of the fire until it goes out.
Shut off the extinguisher and then watch carefully for a rekindling of the fire.
