Hazard Division 1.4 is associated with which fire hazard level?

• A. Moderate Fire
• B. Mild Fire
• C. Severe Fire
• D. No Fire

Answer: (B)

Division 1.4 covers explosives that are designed to pose no significant blast hazard beyond their packaging. In a fire, the energy release from these items is contained within the container, so they are unlikely to create a large, spreading fire or a major explosion affecting the surrounding area. That containment is why the fire hazard level is considered mild—a fire could occur and cause localized damage, but it doesn’t generate widespread or severe fire effects. This contrasts with higher divisions where the potential blast risk is more dangerous, and with none where fire effects are considered negligible, which is not the case here.
