An extinguisher only works if it is charged, reachable, and has not already been used and put back on the wall. Most homes have one of these, and most of them are never checked after the day they were bought. The job is small, but it needs a named owner.

Read the gauge first

Most extinguishers have a pressure gauge with a green band. Check that the needle sits inside the green. If it sits in the red, or the gauge is blank or cracked, the unit needs service or replacement. Check that the safety pin is in place and the tamper seal is intact. A pulled pin or a broken seal means someone may have used it, even if the cylinder looks full.

Look at the body, hose, and label

Look for dents in the cylinder, rust at the base, cracks in the hose or nozzle, and a label you can still read. Do not open the unit, refill it, or try to repair it yourself. Your job is to spot damage and replace the unit.

Mount it on the way out

Place the extinguisher near the exit route, at a height a seated person can lift from the bracket, and not behind the stove or inside a closet. Use the bracket that came with it and screw it into a stud or solid backing, then test that it holds the unit with a firm pull. If Dad resists the bracket, let him choose the spot from two or three options, as long as each one is on the way out of the room.

Name one owner

One person checks the gauge on a fixed schedule, puts the check on a phone reminder or calendar, and writes the check on a card taped to the unit. Two people checking usually means no one checks. The card should show who checked it, what the needle read, and whether the pin and seal were in place.

Replace it after any use

Even a short burst means the unit is spent. Replace it, or have a fire equipment service inspect it before it goes back on the wall. Read the service or replacement note on the label, and note the manufacturer date printed there so you know how old the unit is. An old unit with a full gauge still needs a look.

Teach the rule, then practice once

Get out first, then call the fire department from outside. Use an extinguisher only on a small fire that is still small, with a clear exit behind you. Walk through the pull, aim, squeeze, and sweep steps once with everyone in the house, out loud, with the unit in hand.

Next move

Tonight, find the extinguisher, read the gauge, confirm the pin and seal, and write the owner's name on a card taped to the unit. If the needle is not in the green, replace the unit before anything else in the kitchen gets done.
