There are many safety related reasons for having a mirror in an elevator. For example, you can see what everyone else in the lift is doing – lift mirrors have played a role in spotting theft and even predicting an assault. In Japan – which is thought to be where the lift mirror was first introduced – the purpose is accessibility. Platform lifts can make buildings accessible for wheelchair users where stairs present an obstacle. However, the size of the lift may mean that there is no space for a wheel chair user to turn around inside it. The placement of mirrors helps someone in a wheelchair to back in or out of the lift safely without having to turn. This can prevent accidents and make life easier for anyone with a physical disability using your building.
