Class B: Workshops, storage areas, garages, warehouses, or service and manufacturing areas that contain flammable liquids or gasses. Class C: Anywhere energized electrical equipment is used.
Where do Class B fires occur?
Class B fires are those where the fuel is flammable or combustible liquid. The US system includes flammable gases in their “Class B”. In the European/Australian system, flammable liquids are designated “Class B” having flash point less than 100 °C (212 °F).
How do you put out a Class B fire without an extinguisher?
In many cases, water will only spread the fuel around and create more fire. To extinguish a Class B fire, you want to cut off the oxygen. You can use carbon dioxide gas to dilute the oxygen available and stop the burning. Smothering the fire with bicarbonate (baking soda) or potassium carbonate will also work.
What types of materials do Class B fires involve?
Class B: Flammable liquids such as alcohol, ether, oil, gasoline and grease, which are best extinguished by smothering.
