On-Scene Firefighting


Locations of fire extinguishers, alarm pull stations, and exit points are noted on floor plans located at www.uccs.edu/facsrvs/maps-and-floor-plans.html.

Fires are classified into the following:

  • Class A fires occur in ordinary materials, such as wood, paper, excelsior, rags and rubbish.  Memory jogger:  "Makes anAsh."
  • Class B fires occur in the vapor-air mixture over the surface of flammable liquids, such as gasoline, oil, grease, paints and thinners.  Memory jogger:  "Burns Black smoke."
  • Class C fires occur in or near energized electrical equipment.  Memory jogger:  "Caution electricity."
  • Class D fires occur in combustible metals such as magnesium, titanium, zirconium, lithium, potassium and sodium. Memory jogger:  "Dirty metal fires."


Fire Extinguisher Use:

Personal safety is the highest priority:

  • The building alarm should be activated prior to attempting to fight a fire.
  • Never fight a fire unless you or someone else has called 9-911.
  • If you doubt your ability to extinguish a fire, evacuate.
  • If you need more than one extinguisher to put out a fire, evacuate.


Remember the acronym P.A.S.S.:

  • Pull the pin at the base of the handle.
  • Aim the extinguisher nozzle at the base of the fire.
  • Squeeze and hold the handle (trigger). (Be prepared for the noise!)
  • Sweep the nozzle across the base of the fire.
