Division 1.3 is characterized by which statement?

• A. It has a projection hazard but not a mass explosion hazard
• B. It has a fire hazard with minor blast or minor projectile or both, but no mass explosion hazard
• C. It presents no significant hazards; effects largely confined to the package; examples include practice ammunition or signal cartridges
• D. It consists of very insensitive substances with a mass explosion hazard

Answer: (C)

Division 1.3 refers to items that pose a fire hazard with a minor blast or minor projection, but do not have a mass explosion hazard. In other words, a fire could trigger a small explosion or fling fragments, but it wouldn’t produce a large, widespread blast. This distinguishes it from divisions with only minor effects confined to the packaging, or from divisions involving mass explosion hazards. The statement describing no significant hazards largely confined to the package matches Division 1.4, not Division 1.3. Other divisions cover situations with projection hazards (Division 1.2) or very insensitive materials with a mass explosion hazard (Division 1.6).
