What should explosives not be mixed with?

Answer: C — Oxidizing materials

Explosives should not be mixed with oxidizing materials because this combination can significantly enhance the explosive potential, leading to increased risks during transport, handling, and storage. Oxidizing materials provide oxygen, which can accelerate the combustion of explosives and potentially cause an uncontrolled reaction. The interaction with oxidizers can make an explosive more sensitive to shocks or friction, increasing the likelihood of an accidental detonation. In contrast, while mixing explosives with corrosives, food, or flammable liquids also presents hazards, the risk profile associated with oxidizing materials is particularly concerning due to the potential for dramatic and dangerous interactions that can lead to catastrophic results. This is why safety regulations strictly prohibit the storage or transportation of explosives with oxidizing agents.
