What is an emergency measure?

An emergency measure is defined as a necessary step taken to avoid an imminent public or private injury. This concept is critical in the context of corrections and public safety, where the goal is to protect individuals, prevent chaos, and maintain order in urgent situations. Emergency measures are often reactive, implemented in response to immediate threats that could lead to harm, requiring prompt actions to address the situation effectively.

Routine safety procedures, legal terms related to non-violent conflicts, and guidelines for emergency personnel serve different functions and do not specifically denote actions taken in response to imminent danger. The essence of an emergency measure lies in its immediacy and necessity for preventing harm, which is why choice A accurately captures its definition.
