Using an Extinguisher

 To help you remember how to use an extinguisher, use the acronym PASS:

  • Pull the extinguisher ‘s safety pin.
  • Aim the chemical at the source of the flames rather than at the flames themselves, standing at least 6 feet from the fire.
  • Squeeze the trigger and hold it, keeping the extinguisher upright.
  • Sweep the source of the flames until the extinguisher runs dry.
