The Australian Standards relevant to fire extinguishers include AS 1841 for design and performance, AS 1851 for routine service and maintenance, and AS 2444 for installation.

No. Under Australian Standards, fire extinguishers should be serviced by a competent person who is trained and skilled. Some states may also require licensing. Domestic fire extinguishers should still be visually checked to ensure the pressure gauge is in the green and the extinguisher is full.

There are six classes of fires: Class A ordinary combustibles, Class B flammable liquids, Class C flammable gases, Class D combustible metals, Class E electrical equipment, and Class F cooking oils and fats.

Most fire extinguishers are red with coloured bands that identify the extinguisher type. White indicates Dry Chemical Powder, black indicates Carbon Dioxide, red with no band indicates Water, blue indicates Foam, oatmeal indicates Wet Chemical, and yellow indicates Vaporising Liquid.

A Dry Chemical Powder extinguisher is commonly used in homes because it can suit several common fire risks. A fire blanket is also recommended for kitchen areas. For home use, a 1kg or 2kg extinguisher with a hose is generally suitable, but the right choice depends on the specific fire risks present.
