Division 1.6 refers to which hazard?

Division 1.6 refers to which hazard?

• A. Mass explosion hazard extremely insensitive (prilled ammonium nitrate with fuel)
• B. Extremely insensitive articles with no mass explosion hazard (squib)
• C. Projection hazard (aerial flares)
• D. Fire hazard with minor blast

Answer: (B)

Division 1.6 identifies explosives that are extremely insensitive and present no mass explosion hazard. In other words, even if they’re initiated, they are unlikely to cause a large, system-wide explosion; their hazard is limited and contained. A squib is a classic example—a tiny, highly insensitive device used to initiate a larger charge, categorized as an extremely insensitive article with no mass explosion hazard. The other descriptions refer to hazards with significant blast potential or different hazard types (mass explosion, projection, or fire with minor blast), so they don’t fit 1.6.
