Fire Extinguishers

Fire Safety

Fire equals a state, process, or instance of combustion in which fuel or other material is ignited and combined with oxygen, giving off light, heat, and flame. Fire requires fuel, heat and oxygen to burn. Fire extinguishers apply an agent that will cool burning heat, smother fuel or remove oxygen so the fire cannot continue to burn. A portable fire extinguisher can quickly control a small fire if applied by an individual properly trained.

Fire extinguishers are located throughout every building on campus. To properly use an extinguisher, you must first be familiar with the type of fire each extinguisher is rated for and how it operates.

  • Always know the location of the nearest extinguisher, that it's in operable condition and how to use it
  • Before using the fire extinguisher, evacuate the building by pulling the manual fire alarm pull station to alert other occupants of the facility. (Located near exits and stairs)
  • If a fire alarm pull station is not available, yell or scream out loud "fire, fire, fire"
  • Call 9-1-1 for University Police or have someone else call
  • Only attempt to extinguish small fires- if one extinguisher does not do it, evacuate the area immediately
  • While fighting the fire, do not allow your escape route to become blocked by fire
  • Position yourself between the exit and the fire
  • After an extinguisher is used, contact EH&S to have it serviced or replaced
