What maintenance action is typically performed monthly on Class K extinguishers?

• A. Visual inspection for damage, tamper seal intact, gauge/pressure in operable range, and unobstructed accessibility.
• B. Replace the extinguisher monthly.
• C. Perform a full hydrostatic test on the extinguisher.
• D. Calibrate the gauge to the correct pressure.

Answer: (A)

Monthly checks on a Class K extinguisher are all about a quick, visible check to confirm it’s ready for use. You examine the unit for any obvious damage or corrosion, ensure the tamper seal is intact, verify the pressure gauge shows a reading in the operable range, and confirm the extinguisher is unobstructed and accessible. This ensures the device is in a state where it would function properly if needed. If any of these items aren’t in order, it should be tagged and serviced, rather than attempting any internal or more involved maintenance. More involved actions, like hydrostatic testing or internal inspections, are done on longer, scheduled intervals per standards, not month-to-month.
