How Do You Inspect a CO2 Fire Extinguisher?

To visually inspect a CO2 fire extinguisher, check its location, mounting, tamper seal and weight. Ensure the pull pin is not missing, and check the unit for physical damage. This inspection should be conducted monthly, and it takes less than 15 minutes. Record the results of each inspection in an inspection log.

  1. Ensure easy access to the fire extinguisher

    Ensure the fire extinguisher is not obstructed by file boxes, storage bins or random office equipment, so people have quick access to the unit if needed.

  2. Ensure easy visibility

    Check the extinguisher’s line-of-sight visibility from different room angles. Ensure the unit is visible to all occupants to minimize response time in case of an emergency.

  3. Check the tamper seal

    Check for an undamaged tamper seal. The seal verifies the last date the fire extinguisher was professionally serviced and that it hasn’t been used since that time.

  4. Verify that the pull pin is in place

    Ensure that the pull pin is securely fastened within the handle of the fire extinguisher. The pin should be secured by the unbroken tamper seal.

  5. Weigh the canister

    Locate the canister’s weight label. A CO2 fire extinguisher doesn’t have a pressure gauge that indicates the unit is fully charged. The only way to ensure the canister is full is to weigh it. Use any type of ordinary scale. The typical weight of a CO2 fire extinguisher is 5, 10, 15 or 20 pounds, and the proper weight should be indicated on the label.

  6. Check the unit for physical damage

    Inspect the exterior of the unit for dents, cracks or other physical damage. If the unit displays any physical damage, it should be replaced.

  7. Update the inspection log

    If the unit has an inspection tag attached to the handle or a separate log, update it with the current inspection information.
