  5. 5. Class A Class A Extinguishers will put out fires in ordinary combustibles, such as wood and paper. The numerical rating for this class of fire extinguisher refers to the amount of water the fire extinguisher holds and the amount of fire it will extinguish Used on Wood, Paper, Plastic Class A Fires Green Fire Safety Services
  6. 6. Class B Class B Extinguishers should be used on fires involving flammable liquids, such as grease, gasoline, oil, etc. The numerical rating for this class of fire extinguisher states the approximate number of square feet of a flammable liquid fire that a non-expert person can expect to extinguish Used on Flammable Liquid Fires Green Fire Safety Services
  7. 7. Class C Class C Extinguishers are suitable for use on electrically energized fires. This class of fire extinguishers does not have a numerical rating. The presence of the letter “C” indicates that the extinguishing agent is nonconductive. Used on Electrical Fires Green Fire Safety Services

  9. 9. Water Co2 Type Fire Extinguisher(A Class) Water Fire Extinguishers are good for tackling fires involving burning paper, wood and soft furnishing (Class A fires), as the water soaks into the materials and cools them, while extinguishing the fire. This type of extinguisher does not contain harmful chemicals but has a low fire fighting rating. Due to this water fire extinguishers are usually large and heavy to overcome their lack in fire fighting power. It is also important to remember that water is an electrolyte and conducts electricity. Care must therefore be taken with regards to accidental use on exposed power cables. However, both the weight and the conductivity problems can be overcome by using water extinguishers with environmentally friendly additives. Water extinguishers with additives have a higher fire fighting rating which, therefore, allows the use of smaller and lighter extinguishers. Neither do they conduct electricity. As they are mostly free of harmful substances, water fire extinguishers are especially suitable in households where children have access to the extinguishers and an accidental discharge is possible.

  10. 10. Mechanical Foam Type Fire Extinguisher(A&B.Class) Mechanical Foam Fire Extinguishers, also called AFFF FOAM (Aqueous Film Forming Foam) create a smothering film of foam over the fire, which starves the fire of oxygen. The foam also penetrates porous materials and cools the fire through evaporation of the water content in the foam. As the foam creates a foam carpet on burning liquids like petrol, foam extinguishers are also suitable for flammable liquids and areas where man-made fibres in soft furnishings and carpets might liquidise under the influence of heat. Foam extinguishers are safe for use with electrical equipment, although the electrical equipment will be seriously damaged by the liquid. MAke sure to select a foam extinguisher that has been conductivity tested. Green Fire Safety Services
  11. 11. DCP Type Fire Extingusher (B&C.Class Powder) DRY CHEMICAL POWDER Dry Chemical (Class B & C Fires) MULTI-PURPOSE DRY CHEMICAL FIRE EXTINGUISHERS USER GUIDELINES Use for Class B and C Fires What types of fires can be extinguished with multi-purpose, dry chemical extinguishers Green Fire Safety Services
  12. 12. CO2 Type Fire Extinguisher (B&C. Class Gas) CO2 (Carbon Dioxide) Fire Extinguishers contain only pressurised CO2 gas and therefore leave no residue. This type of extinguisher is suitable for use on fires involving burning liquids (Class B fires), but is also a good solution for quenching fires involving computer equipment and other electrical appliances, as it does not cause damage to the electrical items and does not cause the system to short circuit. It is important to remember that when using CO2 extinguishers there is a possibility that once the smothering CO2 gas has floated away the fire may reignite if the source of the fire is not removed (eg switching off the power supply) or if the materials are still very hot. Please be aware that CO2 extinguishers that are not fitted with double-lined swivel horns may cause your fingers to freeze to the horn during the deployment of the extinguisher. Always select CO2 extinguishers with frostfree horns. CO2 extinguishers are NOT suitable for deep fat fryers, as the strong jet from the extinguisher carries the burning fat out of the fryer and into the room! Green Fire Safety Services
  13. 13. ABC Type Fire Extinguisher (AB&C.Class) What do the A B C ratings mean on Fire Extinguishers? FE Rating - A“A” TRASH–WOOD–PAPER Fire extinguishers with a Class A rating are effective against fires involving paper, wood, textiles, and plastics. FE rating - B“B” LIQUIDS Fire extinguishers with a Class B rating are effective against flammable liquid fires. These can be fires where cooking liquids, oil, gasoline, kerosene, or paint have become ignited. FE rating - C“C” ELECTRICAL EQUIPMENT Fire extinguishers with a Class C rating are suitable for fires in “live” electrical equipment. Fire Extinguisher Ratings Fire extinguishers are classified by fire type. The A, B, C rating system defines the kinds of burning materials each fire extinguisher is designed to fight. The number in front of the A, B, or C indicates the rating size of fire the unit can extinguish. To achieve a Class “A” rating, the extinguisher must be capable of putting out the wood crib, wood panel and excelsior (shredded paper) tests. Ratings are based on the size of the material that can be repeatedly exiting…. Green Fire Safety Services
  14. 14. Clean Agent Type Fire Extinguisher Multipurpose Clean Agent Fire Extinguishers Clean Agents - an overview "Clean Agents" are Hydro Chloro Fluoro Carbons discharged as a rapidly evaporating liquid, which leaves no residue. It effectively extinguishes Class A, B, C Electrical fires by cooling and smothering and does not conduct electricity back to the operator. The clean agent is pressurized with nitrogen gas and is an EPA and FAA approved HCFC blend B agent approved for use on Class A, B and C fires. CLEAN AGENTS are intended for use in areas formerly protected by Halon 1211 hand portable extinguishers such as computer rooms, telecommunications facilities, lean rooms, data storage areas, offices (for protection of sensitive electronic equipment), boats and vehicles.

  15. 15. Aim Aim at the base of the fire. If you aim at the flames, the extinguishing agent will fly right through and do no good. You want to hit the fuel. Green Fire Safety Services
