Laundry lockers are used in places like hospitals and food-processing workplaces where uniforms have to be collected, laundered, then returned to their owners. The locker cabinet contains a number of very narrow lockers, each of whose doors is keyed using a key held by the owner, so that they have access only to their own locker; but the entire array of doors is embedded in a much larger door covering the entire front of the cabinet. Opening this opens all the lockers simultaneously, and requires the use of a master key which is held by whoever collects items deposited in lockers, for laundering, then returned in the same way, after which they items are accessible to owners using their individual small doors.
Some schools in the United States have been reported to have abolished the use of lockers. Security concerns are cited as the reason for this, with the concern being that lockers may be used to store contraband items such as weapons or drugs or pornographic material. There has been some controversy over in what circumstances school authorities or law-enforcement officials are permitted to search lockers, with or without informing the users, or with or without the users being present at the time of the search, and it has been considered a civil liberties issue, particularly in the U.S.
Lockers is a new information and education resource. It assists schools in coping with and preventing the sharing of explicit self-generated images of minors. Intended for use with Junior Cycle SPHE classes, Lockers is supported by a newly developed animation and six lesson plans. Also included in Lockers is an information section for school leaders.
