Water Extinguishers
Should be used for materials such as wood and paper. They must not be used on fires involving electrical equipment or oil.
Foam Extinguishers
Should be used on fires involving burning liquids such as paint and asphalt. They must not be used on fires involving electrical equipment or flammable liquids.
Carbon Dioxide and Dry Power Extinguishers
Are normally used on burning liquids. They are safe for use on fires involving electrical equipment. Neither of these extinguishers have a cooling effect, consequently they are not recommended for use where there is high risk of re-ignition. Use carbon dioxide extinguishers in well ventilated areas because they reduce the amount of oxygen in the air.
Halon Extinguisher
Can be used in most instances including use on electrical equipment. They are recommended for use in the open air or in well ventilated areas because of their toxic properties, so do not use in confined spaces.
