Using a Fire Extinguisher

The use of an extinguisher is very simple. The use of an acronym (P.A.S.S.) can help to remember the steps to use the extinguisher. It is only recommended that fires no bigger than in a waste basket should be smothered using the available fire extinguisher. Stay low and always keep your back to the exit. Always call 911 to report any fire. To use:

  1. Pull the pin.
  2. Aim the nozzle.
  3. Squeeze the handle down.
  4. Sweep at base of flame. 

California law requires that extinguishers be serviced once a year by a licensed service person. Report any that need service to Property Management.

Recommendation to ALL Tenants:

Take a practice "emergency" walk to establish the locations of the emergency exits and fire fighting apparatus and mark them on your floor plan. Read the instructions marked on each fire extinguisher, to assure proper usage — YOU WILL NOT HAVE TIME TO READ INSTRUCTIONS DURING A REAL EMERGENCY.
