How to use Fire Extinguishers 

Even though extinguishers come in a number of shapes and sizes, they all operate in a similar manner.  Here's an easy acronym for fire extinguisher use:
  • P  A  S  S -- Pull, Aim, Squeeze, Sweep
  • Pull the pin at the top of the extinguisher that keeps the handle from being accidentally pressed.
  • Aim the nozzle toward the base of the fire.
  • Squeeze the handle to discharge the extinguisher. Position yourself approximately 8 feet away from the fire. If you release the handle, the discharge will stop.
  • Sweep the nozzle back and forth at the base of the fire. After the fire appears to be out, watch it carefully since it may re-ignite!
