Define "lockdown" in a jail setting.

In a jail setting, "lockdown" refers to a security measure where inmates are confined to their cells due to safety concerns. This action is typically taken in response to situations that may jeopardize the safety of inmates, staff, or the facility as a whole, such as disturbances, riots, or threats of violence. During a lockdown, the movement of inmates is severely restricted, and they are often required to remain in their cells until the situation is under control and deemed safe.

This definition highlights the primary purpose of a lockdown, which is to maintain order and ensure the security of the facility. It is a critical operational procedure that helps mitigate risk and protect everyone within the jail environment.
