Which hazard class includes explosives and flammable solids?

The hazard class that includes explosives and flammable solids is Hazard Class 1. This class is primarily focused on materials that pose a significant risk due to their explosive properties. It encompasses substances that can undergo a rapid reaction when subjected to heat, pressure, or shock, which makes understanding and identifying these materials crucial for effective emergency response.

In addition to explosives, Hazard Class 1 can also refer to certain types of pyrotechnics. However, the distinction between explosives and flammable solids is important, as flammable solids are classified separately under Hazard Class 4. This specificity helps responders identify the correct hazards they may encounter, ensuring proper handling, transportation, and emergency response procedures are followed based on the characteristics of the materials.

Correctly identifying Hazard Class 1 enables responders to implement the appropriate safety measures and mitigations when dealing with potentially catastrophic situations involving explosives.
