- 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

- If the gauge reads in the red area it needs to be serviced immediately.
