Proper fire extinguisher use is easy and straightforward. Some people believe that when used, a fire extinguisher will be difficult to handle or have a heavy "kick-back" effect. Neither is true. If you ever have to use a fire extinguisher to fight a small fire, remember the P.A.S.S. system - PULL the pin, AIM the extinguisher at the base of the fire, SQUEEZE the handle or trigger, SWEEP from side to side.
