Class B fires include fires that involve flammable or combustible liquids and gases. Examples of such substances that can fuel Class B fires are petrol, oil, alcohol, paraffin, acetone, some paints, varnishes, solvents, diesel, heating oil, wax, tar, bitumen, and some liquid-burning plastics. These fires can occur in various settings like workshops, garages, petrol stations, households, industrial plants, and camping areas. The key characteristic of Class B fires is that they involve flammable liquids or substances that can become liquid when heated, and they typically burn with an open flame without embers. Water is generally not effective on Class B fires; suitable fire extinguishers include carbon dioxide (CO2), foam, and dry chemical agents.
