Type of fire:-
In order to determine the right kind of fire equipment to be used, type of fire should be known as well. All tested fire extinguishers are classified to fight that particular kind of fire. To put it simple, every fire equipment refers to the source of fire labelled on it. For example dry powder fire extinguisher can not be used for CLASS A fires. If fire protection equipment is not labeled, it is not tested. Fire can be classified in 4 types-
- CLASS A fire- Fire that started due to normal combustibles such as cloth, paper, cotton etc. comes under this category.
- CLASS B fire:- If fire came about due to gasoline, solvents, oil based paint or other flammables, it falls in this category.
- CLASS C fire:- Fire that transpired due to electric circuits, eletric appliances or fuse boxes etc comes in this category.
- CLASS D fire:- If the source of fire is magnesium and sodium, then it falls in CLASS D category.
