What are the three types of fuel spills?

• A. Small priming spill, small, and large spill
• B. Tiny, small, and large spill
• C. Initial, internal, external spill
• D. Prime, secondary, tertiary spill

Answer: (A)

Spill response uses three practical categories that help you decide how to act quickly: priming spills, small spills, and large spills. A priming spill happens during starting or priming a pump or line and is typically small, but it flags where to concentrate immediate containment efforts to keep it from growing. A small spill is a minor release that can be controlled with standard containment and cleanup procedures without escalating. A large spill involves a substantial quantity and requires urgent, coordinated actions such as activating alarms, setting up barriers, and notifying supervisors and responders. The terminology in this set is chosen because it links the release to the operation that caused it and its volume, guiding the appropriate response. Other term sets mix concepts that aren’t used in this context, like tiny, internal/external, or prime/secondary/tertiary, which don’t fit the standard categories used for fuel spills here.
