Which of the following is NOT one of the five C's in response protocol?

The five C's in response protocol during an active shooter incident are crucial components designed to guide individuals in effectively managing such a threatening situation. Among these components, the concept of "Contain" refers to limiting the shooter's access to other potential victims and restricting their movement. "Control" involves taking charge of the situation as much as possible until law enforcement arrives. "Conceal" means finding a safe place to hide, which can provide protection during an active shooter event. Finally, "Communicate" involves sharing vital information with others, including calling emergency services and alerting those in the vicinity.

Given this framework, "Conceal" is a correct part of the response protocol. However, in this context, it is essential to note that the original request is seeking to identify which term does not belong to the five C's. Therefore, "Control" serves a different function in an active shooter protocol by referring to the management of the incident rather than hiding or taking cover. This is why "Conceal" is identified as the term that does not align with the core response elements required in an active shooter scenario.
