Hazard Division 1.3 corresponds to?

Hazard Division 1.3 corresponds to?

• A. Mass Fire
• B. Explosives
• C. Fragments
• D. Toxic Substances

Answer: (A)

Division 1.3 covers explosives that pose a fire hazard but do not present a mass explosion or projection hazard. They can burn or flare up, potentially causing a fire, but they won’t generate a large, catastrophic explosion. Among the given choices, “Mass Fire” best communicates a significant fire risk, which is the essence of Division 1.3. The other options don’t describe this fire-dominant hazard: “Explosives” is too broad, “Fragments” implies blast fragments, and “Toxic Substances” refers to poisonous materials rather than fire risk. Remember, 1.3 is about fire hazard without the mass explosion or projection hazards seen in other divisions of Class 1.
