The fire class that involves flammable liquids like petrol, solvents, and alcohol is Class B.
Details about Class B Fires
- Class B fires specifically involve flammable or combustible liquids such as gasoline, petrol, alcohol, solvents, oil-based paints, and similar substances. These liquids vaporize easily and ignite rapidly, causing fast-spreading fires.
- Water should never be used to extinguish Class B fires as it can spread the liquid and worsen the fire. Instead, foam, dry chemical powder, or carbon dioxide extinguishers are appropriate for safely putting out these fires.
- Common locations for Class B fires include workshops, garages, petrol stations, industrial plants, and households where flammable liquids are stored or used.
Thus, flammable liquids including petrol, solvents, and alcohol belong to fire Class B, which requires specialized extinguishing agents and caution due to the risk of rapid flame spread and explosion.
