Which division describes minor explosion hazard with no blast or projection hazard (fireworks)?

• A. Division 2.1
• B. Division 1.1
• C. Division 1.3
• D. Division 1.4

Answer: (D)

Understanding how explosives are categorized hinges on the amount of energy released and the kind of danger it poses. Division 1.4 describes materials that produce only a minor explosion energy and do not create a significant blast or projectiles beyond their packaging. Fireworks fit this because they release energy in a controlled, contained way, so the risk is limited to the immediate package rather than a large blast or flying debris. This is different from divisions that involve a mass explosion hazard (danger over a wide area), a projectile hazard (fragments that can travel far), or a fire hazard with a small blast. So fireworks are classed as Division 1.4 because the explosive energy is minor and contained, with no significant blast or projection hazard beyond the package.
