Somebody in the group text said they would grab a fire extinguisher for the kitchen. Then the thread moved on, and nobody mentioned it again. Weeks later, the one in the hall closet is either missing, empty, or sitting behind a laundry basket. Every time someone says I thought you had it, that is a line item. This guide turns that offhand line into a job with a spot, a mount, a check, and a name next to each one.

Step 1: Hold the meeting that picks the owners
Before anyone drives to the hardware store, settle three things in one short conversation. Who buys the unit. Who mounts it. Who checks it each month. The buyer, the mounter, and the checker are often three different people, and that is fine as long as each job has a name. Put them in the group text in one line: Buys, Mounts, Monthly check.
Step 2: Pick the spot
Mount it near an exit, in a place your mother can reach while still standing between the fire and the door. In the kitchen, put it in the room but not right beside the stove, so a grease fire does not cut her off from it. Check that the spot is not behind a door that swings into it, a chair she moves every day, or a shelf that hides the handle. Keep the handle at a height she can lift off the bracket without stretching, and treat the mounting height printed in the manual as the upper limit.
Step 3: Match the unit to the person who will use it
Read the weight on the label before you buy. A heavier unit is harder to lift in a hurry, and the person who has to use it may be your mother, not you. Choose a type labeled for the kinds of fires a home actually has, and confirm it has a pressure gauge with a green zone. A gauge she can read from across the room is worth more than a bigger number on the box.
Step 4: Mount it and log it
Use the bracket supplied with the unit and fasten it into a stud or solid backing, not drywall alone. Set the extinguisher in the bracket with the handle up, the pin in, and the gauge facing out. Then write three things on a card taped inside the closet door or on the bracket: the install day, the spot, and the name of the monthly checker.
Step 5: Teach the three moves
Pull the pin. Aim low at the base of the fire. Squeeze the handle, then sweep side to side. Put those words on the card too. Do not discharge a unit just to practice, because a used extinguisher has to be recharged before it goes back on the wall. Whoever is in the room when a fire starts should know the unit is there, how to use it, and when to leave instead of fighting the fire.
Step 6: Set the monthly check
Once a month, the checker walks to the spot and does four things. Reads the gauge and confirms the needle sits in the green zone. Confirms the pin and tamper seal are still in place. Looks for dents, leaks, rust, or a cracked hose or nozzle. Confirms nothing has been stacked in front of it. If any item fails, the checker does not try to repair the unit. The checker reports it to the buyer in the group text, and the buyer decides whether to recharge or replace it.
Step 7: Decide who replaces it and who pays
Every extinguisher has a service life printed on the label, and any unit that has been discharged needs recharging or replacing before it goes back up. Settle that rule now. Decide who pays, who takes the old unit to be serviced, and who buys the new one if the gauge drops out of the green. Put the receipt in the shared folder so the next person can see the unit's history.
What to bring to the meeting
Your list is short. One name for the buyer, one for the mounter, one for the monthly checker, one for the replacement rule, and one for the spot. If you can answer all five on the same screen, the extinguisher is on the job list instead of drifting through the group text.
