Which hazard class division is moderate fire, no blast?

• A. 1.4
• B. 1.2
• C. 1.3
• D. 1.1

Answer: (A)

When a material presents a fire hazard but does not pose a significant blast or projection risk, it fits the category that accounts for a minor explosion hazard with no significant blast. That category is described as having only a minor explosion hazard and no significant blast or projection. Since there is a moderate fire hazard but no blast, this division is the best match. If there were any blast or projection hazards accompanying the fire, it would move to the fire-hazard division that includes those minor blast or projection risks. If there were a true mass-explosion risk, that would place it in a higher-severity division. References to the other divisions aren’t as fitting because they describe scenarios with blast, projection, or mass-explosion hazards that aren’t present here.
