Which division indicates no significant blast hazard?

• A. Explosives Division 1.6
• B. Gas Division 2.2
• C. Explosives Division 1.4
• D. Flammable Solids Division 4.1

Answer: (C)

Understanding how explosive materials are classified helps you interpret what “no significant blast hazard” means. In Class 1 explosives, divisions describe how serious the blast risk is. Division that denotes a minor explosion hazard and, crucially, no significant blast hazard beyond the packaging, is used for items that may explode but only in a limited way contained within the package. That is the situation described here: the hazard is confined to the packaging, with no large-scale blast danger to the surrounding area. So the division described as having no significant blast hazard beyond the package fits this scenario. The other options refer to different hazard types: a non‑flammable gas has no explosive blast category, and flammable solids involve fire or ignition hazards rather than blast risk. Therefore, they don’t indicate the limited-blast designation described.
