Workplace fire extinguishers should be inspected and tested annually by a certified professional, as well as visually inspected and maintained at least once a month by work staff in order to make sure they accurately perform in an emergency.
A visual inspection and maintenance checklist for fire extinguishers should include:
- Easy access in an emergency
Be sure nothing is blocking or limiting your ability to reach it.
- The recommended pressure level
Many extinguishers have gauges that show when pressure is too high or too low.
- Working parts
Make sure the can, hoses and nozzles aren't damaged, dented, or rusted.
Remove any dust, oil, or grease that might be on the outside of the extinguisher.
- Guidelines and instructions
Some extinguishers need to be shaken monthly, others need to be pressure tested every few years.
In addition, check your fire extinguisher's individual inspection and maintenance guidelines found on the canister. Set up a monthly reminder and assign someone in your lab to routinely check and shake you fire extinguisher (if needed).
