Group H includes ammunition that contains which combination?

The correct answer identifies that Group H includes ammunition that contains explosives and white phosphorous. This classification is important in understanding the nature and hazards associated with handling different types of ammunition.

Group H is specifically designated for munitions that pose significant risks due to their explosive content, as well as the inclusion of white phosphorous, which is known for its incendiary properties and potential to cause fires or severe injuries. Understanding this classification is crucial for personnel involved in the storage, transportation, and handling of hazardous materials, especially when preemptively addressing safety protocols and risk management strategies in military operations or ammunition depots.

The other combinations listed do not accurately reflect the contents categorized under Group H. While propelling charges, flammable liquids, gels, and pyrotechnics have their own classifications, only explosives combined with white phosphorous fits the definition and safety considerations relevant to this group. This specificity helps ensure that the proper handling guidelines and safety precautions are applied.
