Dangers
Not to be used on burning fat or oil or on electrical appliances
Method of Use
Point the jet at the base of the flames and keep it moving across the area of the fire. Ensure that all areas of the fire are out.
Theory
The water takes away the heat of the fire by cooling the burning material
Dry Powder Fire Extinguishers
Suitability
Wood, Cloth, Paper, Plastics, Coal, Liquids such as grease, fats, oil, paint, petrol.
Dangers
The powder is not good at getting into tiny spaces in electrical equipment easily so the the fire may re-ignite.
Not to be used on chip pan fires.
Method of Use
Point the nozzle at the base of the flames and, with a quick sweeping motion, drive the fire away from you until all the flames are out.
Theory
As well as knocking down flames, on burning solids it melts to form a layer or skin that smothers the fire.

These extinguishers are generally not recommended for home use.
Method of Use
The discharge horn should be directed at the base of the flames and the jet kept moving across the area of the fire.

We have Water Fire Extinguishers around the office at work. We had a health and safety induction last week and are well versed in the application and use of fire extinguishers and this just reinforces it all. Thanks!
