Which is a symbol option for Class 1.4 items?

• A. Moderate Fire, No Blast Material
• B. Mass-Detonating Materials
• C. Non-Mass-Detonating Fragment Producing Materials
• D. Mass Fire Hazard Materials

Answer: (A)

Class 1.4 items are explosives with limited hazard: they are not expected to cause a mass detonation, and the primary concern is about a possible, moderate fire and small fragmentation rather than a big blast. The symbol that communicates this situation shows a Moderate Fire hazard with No Blast Material. This matches the nature of Class 1.4 items: they can burn, but they do not present a significant blast threat. The other symbol descriptions describe hazards (mass detonation, larger fire hazards, or fragmentation in a way that implies a greater or different risk), which don’t apply to Class 1.4 items. So the Moderate Fire, No Blast Material symbol is the correct fit.
