What does the term "reactionary gap" refer to?

The term "reactionary gap" refers to the distance maintained to ensure safety in a security context. This concept emphasizes the importance of having a physical space between a security professional and a potential threat or individual of concern. By maintaining this distance, a security personnel can adequately assess the situation, maintain control, and have enough room to react appropriately if the situation escalates. This distance can give the individual time and space to observe behaviors and make informed decisions, ultimately contributing to their safety and the safety of others.

Other options may relate to various safety or communication principles, but they do not specifically address the security focus of maintaining physical space as a protective measure.
