Which is not one of the three C's in spill response?

• A. Concentrate
• B. Control
• C. Contain
• D. Clean

Answer: (A)

In spill response, responders act quickly with three key actions: contain to prevent the spill from spreading, control to stop the flow or source, and clean to remove the material and decontaminate the area. These three actions—Contain, Control, and Clean—define the common three C's you’ll hear in spill protocols. Concentrate isn’t a defined step in this sequence; it would imply focusing attention or increasing the material’s concentration, which isn’t a practical action in the immediate spill-response steps. Therefore, concentrate does not fit the three C's framework, while contain, control, and clean do.
