This question is asked by many people.
It is true that expiry dates are not stamped on the fire extinguisher, but does fire extinguisher expiry date exist?
The answer is No
Fire Extinguisher Expiry Date
Fire extinguisher does not have an expiry date, but not having an expiry date does not mean it will last forever. Both the cylinder and the content do not expire, but it can lose its functionality with time.
It is believed that fire extinguishers if will manage and maintained can last for over 15 years.
Fire extinguisher as we know is very important in our homes, offices and organization in combating fire breakout at the infant stage, and this can make a difference between catastrophic effect of fire and mild damage. Fire extinguisher can only serve this purpose if maintained and sustained in a workable condition.
Though fire extinguisher expiry date is not stamped on the fire extinguisher cylinder, most fire extinguishers have manufacturing date stamped. Knowing the manufacturing date of your fire extinguisher will serve as a guide in drawing out a plan for routine inspection/servicing or replacement. Routine inspection and servicing will preserve the fire extinguisher life for a longer period, but often times replacement is preferred. It is believed that fire extinguisher can last between 5 -15 years or more if well maintained depending on the type.
The duration for servicing or replacing a fire extinguisher depends on the type of the fire extinguisher. For example pressurized water, carbon dioxide and wet chemical extinguisher may need to be serviced every 5 years while dry chemical powder may need to be serviced every 12 years.
This servicing may involve discharging of the fire extinguisher, complete internal examination and recharging to ensure that all component of the fire extinguisher are working correctly.
