What type of hazard does a HD 1.3 munition pose?

• A. Mass fire
• B. Blast
• C. Toxic release
• D. Electrical hazard

Answer: (A)

HD 1.3 signifies a fire hazard with limited blast or fragmentation potential. In practice, items in this hazard division are designed such that a fire can burn and spread, generating a sizable heat source and flames, but they do not present the same catastrophic blast or fragmentation risk as higher-div HF classes. So the primary danger when involved in a fire is a mass fire scenario, not a large explosive blast or toxic release. Electrical hazards aren’t the defining concern for this category, and while there may be some minor blast or projection in some cases, it is the fire spreading that dominates the risk.
