What is a fire extinguisher life expectancy?

A fire extinguisher life expectancy depends on a number of factors. Remember, a fire extinguisher should be tested weekly according to the user's manual. Industry experts recommend replacing non-rechargeable fire extinguishers every 7 years. With rechargeable extinguishers, the life expectancy is based on how well the particular extinguisher will hold its charge. As long as the pointer is in the green area or the pin indicator pops back up when pushed, the extinguisher is properly pressurized and ready to use.
