Which division indicates projection hazard (aerial flares)?

Which division indicates projection hazard (aerial flares)?

• A. Division 1.3
• B. Division 1.2
• C. Division 1.1
• D. Division 1.4

Answer: (B)

In Class 1 explosives, divisions describe the main type of hazard a device presents. Aerial flares are primarily a projection hazard: if they are initiated, they can throw fragments or shrapnel outward rather than causing a large, mass explosion. That’s why they’re categorized under Division 1.2. Division 1.1 involves a mass explosion hazard, where an initiation could trigger a powerful explosion affecting the entire load. Division 1.3 covers devices with a fire hazard or potential for heat and flame, but not significant projection. Division 1.4 refers to articles with a minor explosion or fire hazard. Since aerial flares mainly risk projecting fragments rather than a mass explosion, Division 1.2 is the best fit.
