step 1 Basic Fire Extinguisher Inspection Rules

Fire extinguisher inspections are performed by a licensed inspection company. Many companied do site visits and will service your fire extinguisher at your home or business or even at your vehicle.

New Inspection: When a fire extinguisher is purchased it must be inspected by a certified inspector. Fire extinguishers purchased from regular stores usually do not have an inspection tag. Fire extinguishers purchased from a fire equipment sales and service shop will come with a inspection tag. If you purchased a fire extinguisher from a general store then you can take the fire extinguisher to a fire equipment sales shop and have it inspected.

Yearly Inspection: Fire extinguishers must have a visual inspection yearly. This is a simple and inexpensive inspection that includes:

  • Visually looking at the extinguisher for damage such as rust and dents. Dents on the cup attached to the bottom of the extinguisher to allow the fire extinguisher to stand up on its own are usually ok.


  • Rusted fire extinguishers are to be condemned.

  • Loosen The Chemical: The chemical used in ABC fire extinguishers will separate from the nitrogen used to pressurize it. The chemical then settles to the bottom of the fire extinguisher and becomes cake like. After several years it can become so hard it will no longer flow up the tube and out the fire extinguisher. Loosening the chemical from the bottom of the fire extinguisher is important to keep the fire extinguisher working properly. Turn the fire extinguisher upside down and tap on the bottom with a rubber mallet to loosen the chemical.
  • Re-tagging the fire extinguisher with the dates punched out

6 Year Inspection: Every 6 years it is mandatory to recharge the fire extinguisher. During the 6 year inspection the:

  • Chemical is discharged
  • The top removed
  • Any remaining chemical is dumped out
  • The valve and down tube are inspected for warping and damage
  • The O ring is changed
  • The fire extinguisher is refilled and recharged
  • The Items for the yearly inspection are done

12 year Inspection: Every 12 years there are a few more items to be inspected and actions performed to the fire extinguisher, they include:

  • All the items done during the yearly and 6 year inspection
  • Changing the valve
  • Pressurize the tank with water to see if it has leaks. This is called a hydro test. Most extinguishers will be condemned before the 12 year inspection.
  • Performing all inspection items done during the 1 year and 6 year inspections.

Condemn a Fire Extinguisher: There are several reasons why a fire extinguisher would be condemned:

  • Fire extinguishers made before 1984 are to be condemned.
  • If they are dented or rusted by determination of the inspector. Dents on the base that are not actually part of the cylinder are ok.

step 2 Reading Fire Extinguisher Inspection Labels and Tags

There are several ways a fire extinguisher is marked to show the inspections and service it has had:

Hang Tag: The hang tag is used yearly to indicate when the fire extinguisher was inspected. The tag will have the date of the inspection punched out and will usually say that the inspection expires 12 months from the date punched out.

Label: The sticker label is used every 6 years to

The label and tag on a fire extinguisher tells the date of the last fire extinguisher inspection. These dates will tell you when to recharge the fire extinguisher. If a fire extinguisher is purchased any place other than a fire extinguisher supply shop then it will not have a inspection label or card, it will only have the date of manufacture. A fire extinguisher should be inspected one year after the dates marked on the

fire extinguisher label

Plastic Ring: When the fire extinguisher has its valve removed it will have a plastic ring installed between the valve and the tank. This plastic ring indicates that the valve has been removed, it also will have dates punched to indicate the date that the valve was removed. The color of the ring tells the inspector the size of the ring and has no relation to the inspection of the fire extinguisher.

If you live in a small town there will be a traveling service that goes to businesses to perform the required yearly maintenance on fire extinguishers to keep the extinguishers current with the fire code.

Find your local fire extinguisher supply and recharging company. Look in the phone book or search on the internet for "Fire Extinguisher". Call and check the pricing.
