Which scenario is within the Level I response capability?

• A. Liquefied propane gas leaking from a full 1000 pound tank
• B. Ruptures of high pressure gas lines
• C. Spills requiring evacuation
• D. A small gasoline spill from a motor vehicle accident

Answer: (D)

Level I responders work defensively at the scene, using simple, readily available resources to protect people and contain a release without entering the hazardous area or performing advanced mitigation. A small gasoline spill from a motor vehicle accident fits this level because it can be contained and controlled at the edge of the scene using basic spill-control materials, keep vapors from migrating, and prevent ignition, all while staying outside the hot zone and calling for additional help as needed.

The other scenarios involve larger or more dangerous releases that require isolating the area, shutting off gas supplies, or evacuating people, and they typically need more training and equipment beyond Level I.
