Which fire type has no blast hazard?

• A. Type 2 fire
• B. Type 3 fire
• C. Type 4 fire
• D. Type 1 fire

Answer: (C)

Type 4 fires are characterized primarily by the combustion of ordinary materials such as wood, paper, and textiles. These fires do not produce significant explosive effects, which is why they are considered to have no blast hazard. The materials involved do not release energy in their combustion in a way that would lead to a blast or significant pressure wave. In contrast, other types of fires, such as Type 1, Type 2, and Type 3, may involve the combustion of more volatile substances or involve solid propellants or explosives that could result in explosive events under certain conditions. This distinct lack of a blast hazard in Type 4 fires allows for safer response protocols, reducing the risks typically associated with fire-related incidents involving explosive materials. Understanding the characteristics and risks of each fire type is crucial in managing safety and emergency response effectively.
