Which hazard combination characterizes Hazmat Division 1.3?

• A. Fire Hazard
• B. Minor Blast hazard
• C. Fire Hazard and either a Minor Blast hazard, or Minor Projection Hazard
• D. Mass Explosion Hazard

Answer: (C)

Division 1.3 applies to explosives that can burn and also pose a secondary, relatively small explosive effect. The key idea is that these materials have a fire hazard plus either a minor blast hazard or a minor projection hazard. In other words, they can continue to burn and may generate a small explosion or throw fragments, but they do not have the large, mass-explosion risk associated with Division 1.1. This is different from a pure fire hazard or from a minor explosion hazard alone (which would fall into other subcategories). So the correct characterization is a fire hazard with either a minor blast hazard or a minor projection hazard.
