Hazmat Division 1.4 poses which hazard?

• A. Mass Explosion hazard
• B. Fire Hazard
• C. Projection Hazard
• D. Minor explosion hazard

Answer: (D)

When we classify explosives, the divisions tell us how severe the blast and fragmentation can be. Division 1.4 is used for materials that pose only a minor explosion hazard. The energy release is limited and unlikely to cause a significant blast or dangerous fragments beyond the packaging. This means the main risk is small, very localized effects, and the handling and shipping requirements are designed around this limited hazard. In contrast, choices describing a mass explosion hazard involve a large, powerful blast with widespread impact; a projection hazard means fragments could be hurled with dangerous force; a fire hazard means the material primarily presents burning risks. Division 1.4 sits at the lowest end of explosive risk within the division, hence it is labeled a minor explosion hazard.
