Remember the PASS method:

• Pull the pin.

• Aim the nozzle at the base of the fire.

• Squeeze the handle.

• Sweep side to side until the fire is out.

It depends on the extinguisher type:

• Class A – Ordinary combustibles (wood, paper, cloth).

• Class B – Flammable liquids (gasoline, oil, paint).

• Class C – Electrical fires.

• Class D – Flammable metals (specialized environments).

• Class K – Cooking oils and grease fires (kitchens).

You should:

• Check monthly for pressure, damage, and accessibility.

• Get a professional inspection annually (as required by NFPA 10).

Yes. Most fire extinguishers need servicing or replacement every 5 to 12 years depending on the type. Always check the manufacturer’s label and service tag.

No — even if you used only a small amount, extinguishers lose pressure and should be recharged or replaced after any use.
