NFPA 10, Standard For Portable Fire Extinguishers, requires that fire extinguisher be visually inspected on a monthly basis.  The  visual inspection should include the following procedures:

• Confirm that the extinguisher is visible, unobstructed and located in the designated location

• Verify that the pull pin is in place and that the tamper seal is unbroken

• Examine the extinguisher for physical damage, corrosion, leakage, or a blocked nozzle/hose

• Confirm that the pressure gauge or indicator is in the proper operating range

• Ensure that the extinguisher is full by weighing or hefting the extinguisher

• Make sure the operating instructions on the nameplate are legible and facing outward

• Verify the last professional inspection date on the service tag then sign and date the monthly inspection tag

While performing annual maintenance procedures, your service technician will complete a thorough examination of the extinguisher.  This is intended to give maximum assurance that the extinguisher will operate effectively and safely when needed.  This examination includes the following steps:

• Visually inspect the extinguisher cylinder, handle, hose, and gauge for any damage that may require repair or replacement 

• Visually inspect the pressure gauge to ensure that it is working properly and that the extinguisher is pressurized to the proper operating level

• Verify that the pull pin is securely fastened and that the tamper seal is unbroken

• Record the necessary service data on the extinguisher inspection tag

Every six years, stored pressure extinguishers must be emptied and subjected to applicable maintenance procedures.  In addition to the items completed during the annual maintenance inspection your service technician will complete the following additional steps when performing the 6 Year Maintenance.

• Discharge the extinguisher and pressure using a closed recovery system

• Perform a visual inspection of the interior of the cylinder

• Remove, disassemble and clean the valve assembly

• Remove and replace the valve stem and O-ring

• Fill and recharge the extinguisher

• Replace and secure the pull pin with a tamper seal

• Ensure service data is properly recorded on the recharge label, service collar and inspection tag 

Every 5 or 12 years, depending on the type, extinguishers must undergo a hydrostatic test to verify the integrity of the cylinder.  Our mobile service units are outfitted with the necessary equipment to allow our service technicians to perform the hydrostatic testing on site for most types of extinguishers.  In addition to those items performed during the annual and 6 year maintenance procedures the following steps are performed during a hydrostatic test.

• Fill the extinguisher with water and pressurize it to the applicable test pressure

• Empty the water and dry the inside of the cylinder before refilling and recharging the extinguisher

• Replace and secure the pull pin with a tamper seal

• Ensure service data is properly recorded on the recharge label, service collar and inspection tag 

If an extinguisher is discharged, loses pressure, or is otherwise damaged, it is important to have a trained service technician inspect the extinguisher to determine what repairs are needed.  Our mobile service units are stocked with the necessary parts to allow our technicians to recharge and repair most dry chemical extinguishers onsite.  Certain specialty type extinguishers such as CO2 and Halotron extinguishers may need to be taken off site for recharge or repair.

​

In the event that an extinguisher is non-rechargeable or is damaged beyond repair our mobile service units are stocked with new extinguishers that can be purchased for replacement.

Our technicians can assist with selecting the appropriate fire extinguishers for protecting your property, people, and equipment as well as ensuring compliance with local building and fire codes.  This process includes:

• Identifying the proper type, size, and quantity of extinguishers needed based on the building layout and hazards present

• Providing the required fire extinguisher signage

• Identifying key hazard areas that might require special types of fire extinguishers

• Assisting in the selection and installation of the proper extinguisher mount
