  1. Reducing Hazards in Agricultural Mechanics Ag 1 Safety: Unit 2

  2. Objectives • Reduce hazards in ag mechanics • State the three conditions necessary for combustion • Match appropriate types of fire extinguishers to each class of fire

  3. Reducing Fire hazards • Losses from fire can be prevented through attention and knowledge of how fire works

  4. The fire triangle • To produce fire, 3 components are needed Fuel: any combustible material that will burn Heat: the energy that causes temperture to rise Oxygen: atmospheric gas that must be present for fuels to burn

  5. Preventing Fires in Ag Mechanics • Store fuels in approved containers • Store fuels away from other materials that burn easily • Store materials in areas that are cooler than their combustion temperture • Put out fires by removing one or more elements in the fire triangle

  6. Classes of Fires • Classification is based on how to safely and cheaply extinguish each type of material • Water is the cheapest but not always the safest • 4 classes • A • B • C • D

  7. Class A • Ordinary combustibles • Wood, paper, trash • Does not include any time in the presence of electricity or any type of liquid

  8. Class b • Flammable liquids • Fuels, greases, paints and other liquids not in the presence of electricity

  9. Class c • Electrical equipment

  10. Class d • Combustible metals • Difficult to extinquish • Only a class D extinquish will work

  11. Types of Fire extinguishers • A proper fire extinguisher can put out a fire with in seconds • The key is using the proper extinguisher, using it immediately and in the proper way

  12. Types of Extinguishers • Water with pump or gas pressure—Class A fires • Carbon dioxide gas (CO2)—Class B and C • Dry Chemical—Class A,B,C • Blanket—used for smothering fires on humans or animals

  13. Fire Extinguisher Symbols B A D C

  14. Location of Fire Extinguishers • Place • Where fires are likely to occur • In a clean, dry location near exits • Within easy reach • Should be hung so the top is not more than 3 ½ to 5 feet above the floor, the bottom should be at least 4” off the floor • Should be in a position to remove quickly

  15. Using a Fire Extinguisher • Hold upright, pull ring pin • Start back 10 feet, aim at the base of the fire • Squeeze lever, sweep side to side • http://www.youtube.com/watch?v=uGIleFfKGR4
