How to Check Fire Extinguishers
Fire extinguisher are devices that require a few basic checks to be done on them periodically to ensure that they are fit for service. While professional agencies are responsible for maintenance of extinguishers in commercial buildings, homeowners should be aware of what items to check to ensure that their in-home extinguishers are ready in the event of an emergency.
Check the extinguishers gauge to determine whether or not it is holding a proper charge. The gauges will show that the extinguisher is either undercharged, overcharged, or properly charged. This indicates that the extinguisher is ready for use.
Inspect the hose, nozzle, and connections to ensure that they are free from debris or damage. The nozzle should be clear of any obstructions that could impede the flow of the suppression material.
The extinguisher cylinder should be inspected to ensure that it is clear of rust or damage. It should also be free of any dirt or grime which can obstruct the instruction label and extinguisher class markings.
Hydrostatic testing should be done every five years on the cylinder. This can be verified by locating the most current year stamped into the neck of the cylinder.
