In what situation should a security guard use physical force?

Using physical force as a security guard is appropriate primarily in situations where the guard is protecting themselves or others from imminent harm. This principle is based on the need to ensure safety in potentially dangerous situations.

The justification for using physical force in self-defense or in defense of others is rooted in the legal concept of reasonable force, which allows individuals to take necessary action to prevent injury. This aligns with the security guard's responsibilities to maintain a safe environment and to intervene when there is a clear and immediate threat to safety.

In contrast, other scenarios such as apprehending a thief or making an arrest for the police involve different legal and procedural frameworks that don't justify the use of force solely. In these situations, a security guard must often rely on de-escalation techniques or call the police rather than taking matters into their own hands, unless there are significant risks involved.
