Business owners are required to have all portable fire extinguishers professionally inspected at least once a year, but it is also the responsibility of the business owner to do a visual check of all fire extinguishers on a monthly basis.
The maintenance and replacement of a fire extinguisher depends on the type of extinguisher. Wet chemical fire extinguishers should be tested every 5 years. Dry chemical fire extinguishers should be hydrostatically tested every 12 years, with general maintenance conducted every 6 years.
If it’s been 10 years and you have a rechargeable fire extinguisher, it’s time to recharge! If it has been 12 years since you’ve purchased your disposable fire extinguisher, it needs to be replaced!
