Being a security guard can be an extremely rewarding and satisfying career for a lot of individuals, particularly those with any type of military or police training. The task of a guard is to monitor and protect products, buildings, and people.
To be regarded as a guard that offers security for places or people, you typically need to have a high school degree, pass a criminal background check and undergo a physical fitness test. Based on where you work, there might be additional requirements required, but normally it is not as intensive to become an experienced safety guard as a law enforcement officer.
That having been said, safety guards are well-trained professionals, capable of handling the majority of the risks they're asked to face. Not only are guards necessary to patrol potentially dangerous places, but they're also asked to restrain individuals that are committing a crime on the patrolled property, such as vandalism or theft.
