There are four basic steps to operating a portable fire extinguisher.
An easy way to remember the procedure is to think of the word “PASS.”
ull the pin:
Holding the extinguisher with the nozzle pointing away from you, release the locking mechanism.
In most cases, this means pulling out the pin located below
the discharge lever.
im low: Point the extinguisher nozzle at the base of the fire – the lowest point of the fire nearest you.
Extinguishers are designed to be operated in an upright position.
Always hold the extinguisher vertically.
Never cradle it horizontally.
Squeeze the discharge lever slowly and evenly.
This will release the extinguishing agent and expel it through the nozzle.
weep from side to side:
As the extinguishing agent is expelled, sweep the nozzle from side to side – “driving the fire back.”
As the fire closest to you goes out, you may move closer to
the fire and continue the sweeping motion until the fire is
Remember, hold the extinguisher upright.
If the fire does not go out immediately, get out of the building.
After the fire appears to be extinguished, watch the fire area. If the fire breaks out again, and you have not fully discharged your extinguisher, repeat the process.
Keep in mind that the discharge time of a portable extinguisher can be very short. If you cannot extinguish the fire completely, leave the area immediately and wait for the fire department to arrive.
I recommends that when a small fire breaks out, someone calls the fire department immediately.
You may not be able to put out the fire with your portable extinguisher and waiting before calling the fire department would waste valuable time. The fire department should inspect all fires even after they have been extinguished. Because it is standard procedure for most fire departments to respond to
any call by dispatching a fully staffed fire truck to the scene, some people might feel this step is unnecessary, but from the fire department’s point of view, it is better to prevent a small fire from re-igniting than to deal with a full-blown fire emergency.
