Glass doors
Glass doors pose the risk of unintentional collision if a person believes the door to be open when it is closed, or is unaware there is a door there at all. This risk may be particularly proclaimed with sliding glass doors because they often have large single panes which are hard to see . To prevent injury from glass doors, stickers or other types of warnings are sometimes placed on the glass surface to make it more visible. For instance, in the UK, Regulation 14 of the Workplace (Health and Safety Regulations) 1992 requires the marking of windows and glass doors to make them conspicuous.
