This is a square sign featuring a blue circular background with white writing, which conforms to legislation. It is rigid for easy adherence to a door.
All fire doors require the correct signage. They are designed to help stop the spread of smoke and fire and keep exits and escape routes clear for as long as possible. Automatic doors require space to be clear so that they can close and perform this function, to minimize risk to users of public spaces and help keep everyone safe if incidents occur.
