Which hazard category is commonly associated with materials that may ignite or explode under heat or pressure?

• A. Flammable
• B. Reactive
• C. Explosive
• D. Toxic

Answer: (C)

The main idea is how materials respond to heat, shock, or pressure. When a substance can either ignite or explode under heat or pressure, it behaves as an explosive hazard. Explosives are capable of rapidly releasing energy through detonation when triggered by heat, shock, or friction, which is why this category is used for materials that pose that kind of risk. Flammable materials burn when exposed to ignition sources but don’t necessarily detonate. Reactive materials may undergo violent chemical changes under certain conditions but aren’t defined by explosive detonation. Toxic materials primarily pose health hazards rather than ignition or detonation risks.
