Answers
Water fire extinguishers have a class A rating and are suitable for fighting fires involving solid combustibles such as wood, paper and textiles.
AFFF foam fire extinguishers are highly effective on class A and class B fires (the foam agent helps to prevent re-ignition).
CO2 fire extinguishers were originally designed for use on flammable liquid fires and therefore have a class B fire rating.
ABC powder fire extinguishers are extremely versatile and can be used on class A, class B, class C and electrical fires.
Water mist fire extinguishers are highly effective on class A, B, C, F and electrical fires.
Wet Chemical fire extinguishers are designed specifically for use on fires involving combustible cooking media such as burning oil and fat.
Fire blankets are primarily for use on hot oil fires such as frying pans or small deep fat fryers. They can also be used on someone whose clothing has caught fire. They work by smothering the fire, stopping access to the oxygen fuelling it and extinguishing it
Foam fire extinguishers . They are most suited to extinguishing liquid fires such as petrol or diesel and are more versatile than water jet extinguishers because they can also be used on solids such as wood and paper. The foam extinguishes liquid fires by sealing the surface of the liquid, preventing flammable vapour reaching the air and starving the fire of fuel. They are not suitable for use on free flowing liquid fires.
Water extinguishers are one of the most cost-effective ways to fight fires, those fuelled by solid materials such as paper, wood and textiles. Spraying a jet of water at the burning materials, cooling them and preventing re-ignition. They should not be used on live electrical equipment.
