Abstract
A walk-in chamber has a door opening closable by a door, which, when in the closed position can be either in a locked position or an unlocked position, dependent on the locking device, which includes a sliding bolt engageable with a locking bolt. To enable a person in the chamber to disengage the locking device, a safety mechanism is provided which enables moving the sliding bolt from an engaging position to a retracted position to enable a person to open the door.
