  1. Fire Safety: Fire Extinguishers 01/13

  2. General Information • There are around 250 fire extinguishers throughout all of the buildings on campus. Yearly maintenance is done on every extinguisher so they are functioning properly in case of a fire.

  3. Fire Triangle • The fire triangleis a simple model for understanding the necessary ingredients for most fires. • The following three elements make up a Fire Triangle and must be present before a fire will ignite: • Fuel or combustible material. • Oxygen to sustain combustion. • Heat to raise the material to its ignition temperature.

  4. Types of Fires • Not all fires are the same, and they are classified according to the type of fuel that is burning. If you use the wrong type of fire extinguisher on the wrong class of fire, you can, in fact, make matters worse. It is therefore very important to understand the four different fire classifications. • Class A - Wood, paper, cloth, trash, plastics • Typically leave an Ash • Class B - Flammable liquids: gasoline, oil, grease, acetone • Class B fires generally involve materials that Boil or Bubble. • Class C - Electrical: energized electrical equipment • Class C fires generally deal with electrical Current. • Class D - Metals: potassium, sodium, aluminum, magnesium • It takes special extinguishing agents to fight such a fire.

  5. Types of Fires (cont.) • Most fire extinguishers will have a pictograph label telling you which classifications of fire the extinguisher is designed to fight.

  6. PASS System • The universal system for the use of a Fire Extinguisher is called the PASS system. • P = PULL • A = AIM • S = SQUEEZE • S = SWEEP • Pullthe pin at the top of the extinguisher that keeps the handle from being accidentally pressed. • Aimthe nozzle toward the base of the fire. • Squeezethe handle to discharge the extinguisher, while standing approximately 8 feet away from the fire. If you release the handle, the discharge will stop. • Sweepthe nozzle side to side at the base of the fire. After the fire appears to be out, watch it carefully since it may re-ignite!

  7. When NOT to use a Fire Extinguisher • Never fight a fire: • If the fire is spreading beyond the spot where it started. • If you cannot fight the fire while keeping your back to an escape exit. • If the fire can block your only escape. • If you do not have adequate fire-fighting equipment.

  8. Other Fire Procedures: • Always activate the fire alarm system first. • Call 911 or delegate another individual to call 911. • Only use a fire extinguisher if the fire is very small and you are comfortable/trained in the proper use of an extinguisher.
