Which hazard descriptor describes a substance capable of causing an explosion?

• A. Spontaneously Combustible
• B. Non-flammable compressed gas
• C. Radioactive substance
• D. Explosive

Answer: (D)

The key idea is recognizing how hazard descriptors describe the type of danger a substance presents. An Explosive is a substance that can detonate, releasing a sudden burst of energy and gases that creates a blast. This is different from substances that merely ignite or burn, those that do not burn at all, or radioactive materials which involve radiation hazards. So the label Explosive is the one that signals a substance is capable of causing an explosion, guiding the precautions you’d take to keep a safe distance and control the risk.
