What do you check?
- Pressure gauge: the needle should sit in the green zone. In the red, replace or recharge it.
- Tamper seal: make sure the safety seal is still intact.
- Body, hose and nozzle: no dents, rust, damage or blockage, and the label is readable.
- Access: wipe off dust or grease and keep anything from blocking the way to it.
How often should you check it?
First Alert recommends a quick look at the gauge every week. The U.S. Fire Administration says to follow the manufacturer's schedule, since some models need to be shaken monthly and others pressure tested every few years. A certified fire equipment dealer should service it once a year.
When should you replace it?
Recharge or replace an extinguisher after any use, even a short one. First Alert says most extinguishers need to be refilled or refurbished every 5 to 6 years, so check the manufacture date on the label.
Which kind belongs in a home?
A multipurpose extinguisher labeled A-B-C covers ordinary materials (A), flammable liquids like grease and gasoline (B) and electrical fires (C). Pick one large enough for a small fire but light enough to handle, and look for a UL listing. Keep one near an exit and on every level, including the kitchen, laundry room and garage.
How do you use it?
- Pull the pin.
- Aim low, at the base of the fire.
- Squeeze the lever slowly and evenly.
- Sweep from side to side.
Safety notes
- Fight a fire only if it is small and contained, everyone has been alerted, 911 has been called and you have a clear way out. Otherwise, leave and call 911.
- Keep your back to an exit, and leave right away if the room fills with smoke.
When to call a pro
Have a certified fire equipment dealer service the extinguisher once a year; the local fire department can point to one.
