NFPA 10: Standard for Portable Fire Extinguishers, 2007 Edition is the current standard that has been adopted by the State of Maine. This standard applies to the selection, installation, maintenance and testing of portable fire extinguishers. It also includes the requirement for a monthly "Quick Check" that a fire extinguisher is ready to be used and is likely to work as expected.
NFPA 10 is also the source of information pertaining to hazard identification, minimum sizes and types of extinguishers required for those hazards, placement of extinguishers within a hazard location and the required testing and maintenance intervals of specific types of extinguishers.
NFPA 10 states in part that servicing of fire extinguishers must be done by trained persons at least once each year. It also requires that proper tools, recharge materials and manufacturer's recommended replacement parts be available. This is a service that we provide.
IMPORTANT NOTE: Any extinguisher that is removed from service due to failure of maintenance or testing should be promptly REMOVED from the premises, to avoid being inadvertently returned to service. Kennebec Fire Equipment will not be responsible for any extinguisher that has been removed from service for just cause, and is NOT removed from the premises as such.
The most critical test required for pressurized cylinders including fire extinguishers, is called a Hydrostatic Pressure Test. Each extinguisher receives this test at the factory as part of the manufacturing process. The specific type of extinguisher dictates how often it must then be retested. This test includes both an internal and external examination for damage or corrosion that could effect the integrity of the cylinder.
During the test, the cylinder is exposed to a particular amount of internal pressure, for a particular length of time. Any extinguisher that fails this test for any reason MUST be discharged and removed from service immediately. No further service, including annual maintenance, recharging or inspection may be performed.
Beginning with the manufacturing date or the latest Hydrostatic Pressure Test, all dry chemical type extinguishers must be subjected to a test called Six Year Maintenance. This test involves a complete external and internal examination. Extinguishers that fail this test MUST be removed from service and may no longer be serviced.
This test is required only on dry chemical agent stored pressure extinguishers (pressure inside with chemical).
