EMERGENCY DOOR FURNITURE

1.0.     Emergency door furniture is provided on certain doors to allow occupants to pass through
         the door in an emergency without the need to use a key. These emergency doors are
         fitted with escape devices that usually maintain security and restrict access in one or both
         directions. Furthermore, their design varies with the age of the building, doors and specific
         design requirements at the time of installation.

1.1.     It has been found that staff, students and visitors are unfamiliar with the design and
         purpose of these door releases often find it difficult to operate these devices in the event of
         an emergency. The purpose of this guidance note is to provide staff, students and visitors
         with visual and descriptive information on their safe and effective operation.

  type of furniture is not suitable for continuous/everyday use by occupants, but designed for
