A corrections officer is an officer responsible for the custody, safety, security, and supervision of inmates in a prison or any other correctional facility. Traditionally, terms such as jailer, jail guard, prison guard, and turnkey were used to refer to a corrections officer.
Historically, terms such as jailer (also spelled jailor or gaoler), jail guard, prison guard, and turnkey have also been used. In some countries, the Prisons service is part of the Police department. Corrections officers are responsible for the care, custody, and control of individuals who have been arrested and are awaiting trial while on remand or who have been convicted of a crime and sentenced to serve time in a prison or jail. They are also responsible for the safety and security of the facility itself.
