Which division describes fire hazard with minor blast or projection hazard (propellant explosives)?

• A. Division 1.1
• B. Division 1.4
• C. Division 1.3
• D. Division 2.1

Answer: (C)

In Class 1 explosives, divisions are based on the dominant hazard type. The division that is described as a fire hazard with minor blast or projection hazard is the one used for materials that burn readily and may cause only a small blast or throw of fragments. Propellant explosives primarily pose a burning (fire) hazard, and if they do produce any blast or projection, it’s minor. That makes this division the best match for propellant explosives. It’s different from the divisions for mass explosion hazards (where a large blast could occur) or for materials where projection is the main risk, and it’s distinct from other classes like flammable gases.
