Fire

• To ignite and burn, a fire needs three elements.
• FUEL - can be anything that will burn, e.g. wood,
  furniture, flammable liquid, gas, etc.
• OXYGEN - or air in normal circumstances, will
  allow a fire to burn.
• HEAT - a minimum temperature is needed but a
  naked flame, match or spark is sufficient to
  start a fire, especially if in contact with
  something flammable.
• All three elements must be present for a fire to
  start. This known as The Fire Triangle
• If you remove one element you can put a fire out.

• You can help reduce the risk of fire being
  started, or people being harmed if there is a
  fire, by
• not smoking at work (no smoking areas should be
  designated)
• maintaining all electrical appliances in a safe
  manner
• good housekeeping, being tidy
• removing combustible materials outside to a safe
  place.

• Help prevent fires by
• not storing highly flammable liquids unless
  essential
• disposing of cigarettes carefully
• having clearly marked fire points nearby
• having procedures if there is a fire

Reducing fire risk 3

• Help prevent fires by

Classes of fire

• Combustible and flammable fuels involved in fires
  have been broken down into five categories
•       Class A fires - are fires
  involving organic solids like paper,
  wood
•       Class B fires -are fires
  involving flammable liquids
•       Class C fires -are fires
  involving flammable gasses
•       Class D fires -are fires
  involving metals
•       Class F fires - are fires
  involving cooking oils
•  
• (Electrical fires have no classification, as
  electricity is a source of ignition that will
  feed a fire until switched off or isolated.)

Which fire extinguisher?

• Never use hose reels, water extinguishers or any
  other means of extinguishing with water on
• live electrical apparatus
• any fire involving fats, oils or paints
• any metal fire
