This is a rectangular sign featuring a blue background with white exclamation point alongside 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. These doors must be kept shut to allow this function. This minimizes risk to users of public spaces and helps to keep everyone safe during incidents.
