Is that definitive? Are you saying that label is only applied to boosters?
Hope so.
Dunno. Need an expert here. Im not an expert.
Hazard Classification The hazard classification system is based on a system established for international use by the United Nations Organization (UNO). The UNO system consists of nine classes of dangerous material. The nine classes and the types of hazardous materials involved are shown in table 7-1 of NAVSEA OP 5, volume 1. You will deal primarily with hazard class-1 material (ammunition and explosives, Department of Transporta- tion (DOT) classes A, B, and C; blasting agents). The ammunition and explosives hazard class 1 is further subdivided into six divisions. These divisions are based on the characteristics and predominance of the associated hazards and on the potential for causing personnel casualties or property damage. The divisions and types of hazards expected are as follows: 1. 2. 3. 4. 5. 6. Division Designator 1—Mass detonating Division Designator 2—Non-mass detonating, fragment producing Division Designator 3—Mass fire Division Designator 4—Moderate fire, no blast Division Designator 5—Very insensitive Division Designator 6—Extremely insensitive STORAGE COMPATIBILITY The assignment of class-1 ammunition and explosives into six divisions does not necessarily mean that the different items in a division may be stored or transported together. Compatibility groups determine storage and transportation compatibility for rail and motor modes, while the class and division designators determine segregation requirements for carriage by vessels. Explosive articles that differ in minor respects maybe assigned to different divisions if their predominate haz- ards differ. Storage Compatibility Groups A compatibility group accompanies the hazard class to complete the hazard classification designation.
