Maintenance[edit | edit source]

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.

  • Cleanliness

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).
