Foam extinguishers are suitable for use on fires involving wood, paper, textiles, plastics etc. and also suitable for use on fires involving burning liquids such as paints, oils, petrol etc. They are not suitable for use on cooking oil fires (see wet chemical extinguishers.)
Foam spray extinguishers put out fires by cooling (they are water based extinguishers) and also by smothering, the foam helping to exclude oxygen.
Available sizes: 1 litre, 2 litres, 3 litres, 6 litres and 9 litres.
