As a fire warden, it is important to have a basic understanding of the different types of fires that can occur. Class A fires involve solid materials such as wood, paper, rubber, plastic and cloth. Class B fires involve flammable or combustible liquids, such as petrol, oil and paint. Class C fires involve flammable gases, such as propane, butane and methane. Class D fires involve flammable metals, such as potassium, aluminium and titanium. Class F fires involve cooking oils and fats. Knowing the different types of fires that can occur will help you to be better prepared in the event of a fire and will enable you to provide more effective fire safety training to others.
