How to Check Fire Extinguishers
Complete checklist with climate-adjusted recommendations
Overview
Place one in the kitchen, one in the garage, and one per floor. Check the pressure gauge monthly and replace every 12 years.
Step-by-Step Guide
Verify you have enough extinguishers
You need at minimum: one in or near the kitchen (not directly next to the stove — place it 10–15 feet away so you can reach it during a fire), one in the garage or workshop, and one on every floor of the home including the basement. For larger homes, add one near bedrooms.
Confirm correct extinguisher type
For kitchens, use an ABC-rated extinguisher (handles ordinary combustibles, flammable liquids, and electrical fires). For kitchens with a deep fryer, consider adding a Class K extinguisher. Garages and workshops should have an ABC extinguisher rated at least 2A:10B:C.
Check the pressure gauge
Look at the pressure gauge on the neck of the extinguisher. The needle should be in the green zone. If it is in the red zone on either side, the extinguisher needs to be recharged or replaced. Do this check monthly.
Inspect the physical condition
Check for dents, rust, corrosion, or a cracked hose. Ensure the nozzle is not blocked. Verify the locking pin is in place and the tamper seal is intact. If the body is dented or corroded, replace the unit.
Shake dry-chemical extinguishers
Gently turn dry-chemical extinguishers (the most common household type) upside down and shake them a few times, then set them upright. This prevents the powder from settling and compacting at the bottom, which can cause failure during use.
Verify the manufacture date
Find the manufacture date stamped on the bottom or label. Disposable extinguishers should be replaced every 12 years. Rechargeable metal extinguishers should be professionally serviced every 6 years and hydrostatically tested every 12 years.
Confirm mounting and accessibility
Extinguishers should be mounted on a wall bracket at a height of 3.5 to 5 feet above the floor, visible and unobstructed. Do not store them in closed cabinets, behind doors, or under sinks where they are difficult to reach in an emergency.
Review the PASS technique with household members
Teach everyone the PASS method: Pull the pin, Aim the nozzle at the base of the fire (not the flames), Squeeze the handle, and Sweep side to side. Practice the motions without discharging the extinguisher so the steps are familiar.
What You'll Need
Tools
- - Wall-mount bracket and screws (if not already mounted)
- - Screwdriver
Materials
- - ABC-rated fire extinguisher (5 lb minimum per unit)
Cost Estimates
DIY Cost
$20–$60 per extinguisher
Professional Cost
$50–$100 per extinguisher for professional recharging and inspection
Safety Tips
- Never attempt to fight a fire that is larger than a wastebasket or has spread to the ceiling — evacuate immediately and call 911.
- Always position yourself between the fire and an exit so you can escape if the extinguisher fails.
- After using an extinguisher, even partially, it must be recharged or replaced before it is reliable again.
When to Call a Professional
Call a fire safety company if you need rechargeable extinguishers professionally serviced, hydrostatic testing, or if you want a fire protection survey of your home. Many local fire departments also offer free home fire safety inspections.
Pro Tip
Write the purchase date on the extinguisher label with a permanent marker right when you buy it. Set a calendar reminder for monthly pressure gauge checks and annual physical inspections.
Common Mistakes to Avoid
- Placing the kitchen extinguisher right next to the stove, where a grease fire would block access to it.
- Buying the cheapest extinguisher without checking the rating — look for at least 2A:10B:C for general home use.
- Storing extinguishers in hard-to-reach locations like under the kitchen sink or in a back closet.
- Never shaking dry-chemical extinguishers, which causes the powder to compact and fail when needed.
- Keeping extinguishers past their expiration date and assuming they will still work.
