What is the control phase of chemical spill management?

• A. Immediate steps should be taken to safely stop the flow of the material from the source.
• B. Contain the spill
• C. Clean the area
• D. Notify authorities

Answer: (A)

The control phase focuses on stopping the release at its source to prevent more chemical from escaping. In practice, this means taking immediate steps to safely halt the flow from the source—shutting off pumps, closing valves, sealing leak points, or isolating the equipment if it can be done safely. Once the source is stopped, responders can more effectively contain the spill to limit spread and then proceed to cleanup. Notifying authorities is important for incident management, but it’s about coordination rather than stopping the flow itself. Containing the spill and cleaning the area come after control, once the release is halted.
