- 2. FIRE HAZARD • Condition that favor the development or growth of fire with a oxygen, fuel and heat. • A Fire Hazard is any condition or situation that increases the likelihood of fire starting or poses a significant risk in the event of a fire.
- 3. ELEMENTS OF FIRE TRIANGLE •The Fire Triangle or combustion triangle is a simple model for understanding the necessary ingredients for most fires. The triangle illustrates the three elements a fire needs to ignite. Heat, fuel, and an oxidizing agent. (Usually oxygen).
- 4. TYPES OF FIRE HAZARDS 1. ELECTRICAL HAZARDS 2. PROCESS AND OPERATIONS HAZARDS 3. HOUSE HAZARDS 4. STORAGE HAZARDS 5. SMOKING HAZARDS 6. FRICTION HAZARDS 1. ELECTRICAL HAZARDS - An electrical hazard is a type of fire that originates from electrical equipment or wiring. Ex: • Damaged wiring Broken switches, sockets • Damaged plugs overloaded circuits • Wet wires Liquid near computers
- 5. 2. PROCESS AND OPERATION RELATED HAZARDS - Cutting and wedding operations which use open flame and produce spark. 3. HOUSE HAZARDS • Dry leaves are burn by the sunlight • If gas burner not turn off then there is possibility of explosion.
- 6. 4. STORAGE HAZARDS • Flammable or combustible materials stored too close to heat sources • Materials stored in damaged container • materials stored in unlabelled containers • containers not tightly sealed
- 7. 5. SMOKING HAZARD • Smoking around flammable or combustible materials • Smoking on bed • Smoking in areas where there is an accumulation of plastic or metal powders that may become explosive. • Throwing matches or cigarettes or cigars on table or any othe place
- 8. 6. FRICTION HAZARD • Choking or jamming materials • poor adjusment of moving parts
- 9. CLASSIFICATION OF FIRE There are 5 classes of fires: 1. Class A 2. Class B 3. Class C 4. Class D 5. Class K 1. Class A fire - Are fires that involve ordinary combustible materials such as cloth, wood, paper, robber, and many plastics.
- 10. 2. Class B fire - Are fires that involve flammable and combustible liquids such as alcohol, diesel oil, oil-based paints, lacquers etc. and flammable gases. 3. Class C fire - Are fires that involve energized electrical equipment.
- 11. 4. Class D fire - Are fires that involve combustible metals such as magnesium, titanium, and sodium. 5. Class K fire - Are fires that involve vegetable oils, animal oil, or fats in cooking appliances. This is for commercial kitchens, including those found in restaurants, cafeterias.
- 12. FIRE EXTINGUISHER Fire can be extinguished by: • COOLING - The fuel by removing heat by applying water. • SMOTHERING - By cutting off oxygen supply (e.g. by application foam, carbon dioxide). • STARVING - The fire by removing the fuel (e.g. stopping gas flow during a pipeline fire). • INHIBITION - By stopping the chain reaction (e.g by applying dry chemical powder).
- 13. TYPES OF FIRE EXTINGUISHERS 1. WATER EXTINGUISHER 2. DRY CHEMICAL/ POWDER EXTINGUISHER OR FOAM EXTINGUISHER 3. CARBON DIOXIDE EXTINGUISHER 4. DRY POWDERS (special) EXTINGUISHER 5. WET CHEMICAL EXTINGUISHER 1. Water Extinguisher - are suitable for use on fires involving solid combustibles, such as a wood, paper, fabrics and other class A fire risks.
- 14. 3. CARBON DIOXIDE EXTINGUISHER - It dontains carbon dioxide for use against electrical fire 2. DRY CHEMICAL / POWDER EXTINGUISHER OR FOAM EXTINGUISHER - Put out fire by coating The fuel with a thin layer of dust, separating the fuel from the oxygen in the air.
- 15. 4. DRY POWDER (special) EXTINGUISHER - Spray dry powders on combustible metals like magnesium, titanium, sodium, potassium and Al. 5. WET CHEMICAL EXTINGUISHER - Use a wet, potassium acetate- based, low pH agent to put out "working" fires in which there are animal or vegetable oils and fats.
- 16. Below are some other common causes of fire: • Kitchen Stoves • Faulty wiring • Smoking in bed • Lighting • Flammable liquids • Candles • Children
