Operation of a Portable Fire Extinguisher

NOTE – A fire extinguisher is designed to extinguish small fires. Any time an employee utilizes a fire extinguisher; they must always have an exit/escape from the situation at their back. Never place a fire situation between you and your exit. If a fire extinguisher is utilized in or around a University building, the operator must report the incident as a fire to 9 1 1 as soon as possible.

Remember P.A.S.S.

  • Pull and TWIST the pin from the extinguishers handle
  • Aim the hose or nozzle towards the fire
  • Squeeze the handles of the extinguisher together
  • Sweep the extinguishing agent at the base of the fire
