Location of fire extinguisher

  • Fire extinguishers should be easily accessible and located near unobstructed exits.
  • Extinguishers should be installed away from potential fire hazards such as heating appliances.
  • Rule of thumb is to have extinguishers available every 75 feet.

Proper Extinguisher use
Make sure you are in a location where you are near an exit, so if the fire gets too large to handle you will not be trapped and still have a way out.

Use the P.A.S.S. technique to extinguisher the fire:

PULL the pin
AIM the nozzle at the base of the fire
SQUEEZE the handle
SWEEP back and forth at the base of the fire until no flames are visible


  • Fire extinguishers in the workplace are required to be serviced annually (by a licensed contractor)
