Fire extinguishers are an essential part of workplace fire safety, but simply having them on the wall is not enough. Business owners need to know how often fire extinguishers should be inspected, what to look for during a visual check, and when professional fire extinguisher maintenance is necessary.

For businesses in Maine, staying on top of fire extinguisher inspections helps support workplace safety and preparedness.


How Often Should Fire Extinguishers Be Inspected?

For workplaces covered by OSHA's portable fire extinguisher standard, fire extinguishers must receive monthly visual inspections and annual maintenance checks. Certain extinguisher types also require additional maintenance or periodic hydrostatic testing.


These checks serve different purposes. A monthly inspection looks for visible problems, while annual maintenance involves a more thorough assessment of the extinguisher's condition and service needs.


Keeping a consistent inspection schedule helps businesses identify potential problems before an emergency occurs.


What Should You Check During a Monthly Fire Extinguisher Inspection?


A monthly fire extinguisher inspection checklist can help employees identify visible issues. Check that each extinguisher:

  • Is easy to access and has clear signage where needed.
  • Is in its designated location.
  • Shows no obvious signs of damage, corrosion, or leakage.
  • Has its safety pin and tamper seal in place.
  • Has an appropriate pressure gauge reading, if equipped.
  • Has a readable label and appears ready for use.


If an extinguisher is damaged, appears undercharged, or has been used, arrange for appropriate service. Visual checks do not replace required professional maintenance.


When Does a Fire Extinguisher Need Professional Service?

Fire extinguisher maintenance may be necessary when a unit has been used, shows signs of damage, has a pressure problem, or reaches a required service or testing interval.


Professional fire extinguisher service can include inspection, maintenance, recharging, and determining whether an extinguisher needs repair or replacement. Requirements vary by extinguisher type, so service should follow the applicable standards and manufacturer instructions.


Businesses should also maintain appropriate fire protection when an extinguisher is removed from service for maintenance or recharging.
