AUST – It is recognised by the Building Regulations that revolving doors have inherent hazards whereby the Building Code of Australia (BCA) does not permit revolving doors to serve as an exit door for evacuation purposes and they are not permitted to be installed in class 9a health care buildings and in resident use areas in class 9c aged care buildings. AS 1428.1 and AS 1288 have a significant input in the design and a glazing audit.
In addition, revolving doors are not permitted under the Disability Discrimination Act legislation of AS 1428.1-2009‘Design for access and mobility – General requirements for access – New building work’ to serve as an accessible path of travel for people with disabilities into and throughout a building.
The design and operation of revolving doors are therefore not controlled and regulated by the BCA and AS 1428.1-2009 in relation to the speed of revolving doors, the design and size of openings.
However, this does not absolve an architect, designer or building owner from providing a safe workplace for the occupants under other legislation, such as Work Safe, and therefore if a revolving door exists in the building or is proposed to be installed, the architect, designer and building owner will need to ensure the design and operation of the revolving door is suitable for the purpose, location and is safe for the occupants to use.
The only provision of the BCA that is applicable to the design of revolving doors and their associated curved panels, is for the installation of any glass to be in accordance with AS 1288-2006 ‘Glass in buildings – Selection and installation’. The requirements of AS 1288 are to reduce the risk of injuries that can result from glass breakage by the installation of safety glass and enhancing a person’s awareness of the presence of glass by making the glass visible (manifestation).
Clause 5.19 of AS 1288 stipulates the minimum requirements for markings on glass if the presence of glass in a door, side panel or a panel capable of being mistaken for a doorway or opening is not made apparent by transoms, colonial bars or other decorative treatment, then the glass must be marked to make it visible.
The markings must be readily apparent and note that the requirements in the code AS 1288 are only a minimum and therefore the designers and building owner will need to consider that there maybe circumstances in which the glass is installed that may require additional markings and increased heights of the markings so that the band or markings are readily apparent.
Whilst AS 1428.1-2009 does not apply to revolving doors, there are now increased markings required for glass doors and side lights that may still apply to the curved panels of revolving doors, if they are capable of being mistaken for a doorway or opening and that are located adjacent to swinging entry and exit doors in an access way. The markings must comprise a contrasting 75mm wide solid line across the full width of the glazed panel in accordance with AS 1428.1-2009, logos can be used provided the minimum markings of 75mm wide solid line is maintained.
Building owners and property managers should consider whether a glazing audit should be performed to establish any risks that are existing.
