Examples of items in Group H would likely include?

Items in Group H are classified as hazardous materials relating specifically to incendiary agents and pyrotechnics. This classification recognizes the unique risks posed by materials that can ignite or explode, which are often used in various applications, including military and firefighting contexts. Incendiary agents are substances that can ignite other materials upon contact, and pyrotechnics encompass fireworks and flares that create visual effects through combustion.

In contrast, explosives without any initiation do not belong to this group as they require a detonator or similar device to become hazardous. Similarly, dry lead styphnate, a specific chemical compound, does not encompass the broader category of incendiary agents and pyrotechnics, as it serves a more specialized role in detonators rather than being classified strictly within the incendiary category of Group H. Nuclear materials also fall under a different classification due to their radioactive properties and the specific regulations governing them, separating them from the characteristics of incendiary and explosive materials. Thus, the recognition that incendiary agents and pyrotechnics are primary examples in Group H solidifies why these materials are classified accordingly.
