OSHA requires that if we provide fire extinguishers for employees to use, employees must be trained in how to properly use them. Therefore, all employees should know the following.


There are four different types of fires:

  • Type A - ordinary combustibles such as wood, cloth, paper, rubber and many plastics
  • Type B - flammable liquids, such as gasoline, oil, grease, tar, oil-based paint, lacquer, and flammable gas
  • Type C - energized electrical equipment, including wiring, fuse boxes, circuit breakers, machinery and appliances
  • Type D - combustible metals such as magnesium and potassium

Most of the fire extinguishers on our campuses are ABC. Some, such as in the College of Pharmacy or in computer rooms, are Halon 1211. Halon 1211 is non-corrosive, non-abrasive, and can be hazardous in areas with little ventilation.

Many fire extinguishers discharge their contents at a rate of 8-15 seconds.


Immediately call the following:

  • Oklahoma City - Campus Police and Public Safety at 405/271-4911

  • Schusterman Center - Campus Security at 918/660-3333

  • All other locations - call 911

Remember PASS:

  • Pull the pin
  • Aim the discharge toward the base of the flames. Do not aim the fire extinguisher directly onto the source, as it may spread the flames. Begin discharging 8-10 feet away from the fire source.
  • Squeeze the handle
  • Sweep from side to side

If the fire is too large to handle, pull the handle on the nearest fire box, evacuate the building and call 1-4911 (OKC) or 911 (Tulsa).
