Which step starts the five-step process?

• A. Communicate & notify
• B. Secure the cargo
• C. Control & limit
• D. Clean up

Answer: (C)

The action that starts the sequence is about stopping the hazard at its source. Controlling and limiting the release is the immediate priority because it reduces the chance of further spread, exposure, or environmental impact. Once the release is under control, you can safely notify others, secure the cargo to prevent additional leakage, and then begin cleanup without unchecked danger escalating. Trying to address downstream steps before you arrest the release would risk making the situation worse, so this first step sets the foundation for all subsequent actions.
