Which of the following is NOT one of the five C's for Explosives?

Explanation:
In explosives safety, the five Cs are Confirm, Clear, Check, Contain, and Communicate. Each step guides a quick, safe response: Confirm verifies information and intent; Clear removes people from the area; Check assesses conditions and risks; Contain isolates the incident; and Communicate relays status and instructions. Calibrate isn’t part of that sequence—calibration is about ensuring instruments read accurately, which is a separate task outside the five Cs. Since Calibrate does not belong to the established set, it’s the correct choice for NOT being one of the five Cs.
