What source is best used to determine the explosive hazard class/division of a specific munitions item?

The Joint Hazard Classification System (JHCS) is the most suitable source for determining the explosive hazard class or division of a specific munitions item because it provides a standardized and systematic approach used across the military to classify the hazards associated with explosive materials. JHCS takes into consideration the physical and chemical properties of explosives as well as other factors like their intended use, which is essential for accurate classification.

This system specifically addresses the United States military's requirements and provides the necessary guidance to ensure safety in handling, storage, transportation, and usage of munitions. The classification can affect logistics and safety protocols, making it a critical reference for military personnel involved in munitions operations.

The other sources, while useful, do not focus exclusively on the hazard classification of munitions. For example, Department of Transportation Guidelines are more comprehensive and cover various modes of transportation regulations but may not be specifically tailored to military munitions. The Explosive Safety Manual contains important safety policies and procedures related to explosives but does not extensively classify the items themselves. Similarly, USAF Safety Regulations provide safety directives and guidelines, but they are broader and encompass various safety topics beyond munitions classification. Thus, JHCS is uniquely suited for determining the explosive hazard classification
