In hazmat terminology, what is the difference between a spill and a leak?

• A. Spill is a release of liquid; leak is slow leakage; both require containment.
• B. Spill is always bigger than leak; both require immediate evacuation.
• C. Spill is only for liquids; leak only for gases; both don't need containment.
• D. Spill and leak are the same; no difference.

Answer: (C)

In hazmat terminology, the distinction revolves around what is released and how it escapes. A spill refers to the release of a liquid onto surfaces, the ground, or water, often spreading as it moves and needing cleanup measures like absorbents, containment dikes, and surface remediation. A leak, on the other hand, implies a breach or slow escape of a gas or vapor from a vessel, pipe, or fitting, concentrating hazards in the air and requiring actions such as stopping the source, ventilation, and gas monitoring to prevent inhalation or ignition. In practice, both situations demand containment and control to prevent further spread and exposure, even though the general idea used in some questions is that spills involve liquids and leaks involve gases. The key concept to take away is the state of the material and the release mode: liquids spread on surfaces during a spill, while gases or vapors escape through a breach during a leak, with corresponding protective responses.
