19.  CAUSES OF FIRES  METHODS OF PREVENTING FIRES  METHODS OF EXTINGUISHING FIRES  EMERGENCY PROCEDURES IN THE EVENT OF A FIRE

20.  Fire occurs only when three factors are combined. 1. Fuel 2. Oxygen 3. Heat ***The absence of any one of these factors will prevent a fire.***

21.  Your responsibilities in a fire situation are:  Yell “fire” to make everyone in your area aware of the situation.  Assess the fire condition and decide if you have the necessary resources to extinguish it, or if you need help.  Remember: You are not a trained fire fighter.  YOU SHOULD NEVER PUT YOUR LIFE IN DANGER.

22.  Class A  Class B  Class C  Class D

23.  Fires in wood, paper, cloth, and similar common materials.  These materials usually form glowing coals, which help to sustain the fire.  Can be stopped most readily by cooling with water or watery solutions. Water has the advantage of usually being plentiful and cheap.

24.  Blazes in flammable liquids such as gasoline, oil, or grease.  The material and the fire would float and spread if a stream of water were used on the flames.  Such blazes are smothered; that is, oxygen from the air is cut off.

25.  Fires in charged electrical equipment  Should be put out by an agent which does not conduct electricity.

26.  Certain combustible metals, such as magnesium, titanium, potassium and sodium.  These metals burn at high temperatures and give off sufficient oxygen to support combustion.  They may react violently with water or other chemicals, and must be handled with care.

27. The common types of fire extinguishers:  Pressurized Water (wood,paper,trash)  Carbon Dioxide (electrical)  Dry chemical (A, B, C)  Extinguishers that foam are not to be used on electrical fires.  Class D fire extinguishers contain special chemicals that can extinguish combustible metal fires.

29.  P = Pull the pin.  A = Aim the nozzle at the base of the fire.  S = Squeeze the handle.  S = Sweep from side to side.  The PASS Method will work on all types of extinguishers.

30. P ull the pin This will allow you to squeeze the handle in order to discharge the extinguisher

31. A im at the base of the fire Aiming at the middle will do no good. The agent will pass through the flames.

32. S queeze the handle This will release the pressurized extinguishing agent

33. S weep side to side Spray the extinguisher at the base of the fire. Cover the entire area that is on fire. Continue until fire is extinguished. Keep an eye on the area for re-lighting.

34.  Stay upwind of to the fire.  Stay low, never try to work over top the fire.

35.  Spray the extinguisher at the base of the fire.

36.  Never allow the fire to get between you and a route to escape.

37.  Never go into a unknown area to fight a fire.

38.  The extinguisher should be mounted on the wall.  The area in front of the extinguisher shall be clear. No obstructions  The pressure gauge should be in the green zone  The inspection tag should show that the extinguisher has been inspected within the last year.

39.  Your responsibilities in a fire situation are:  Assess the fire condition.  Yell “fire” to make everyone in your area aware of the situation.  Remember you are not a trained fire fighter. You should never put your life in danger.
