NZS 4238 – Code of practice for fire safety in atrium buildings

Deals with the special features and precautions to be incorporated in the design of a multi-storey building having an internal courtyard under a space (atrium) which extends upwards for several floors but is not open at the top. The object is to ensure safety of life in the event of a fire in any area which opens on to the atrium space. The Code is supplementary to the basic building code fire protection requirements. It deals with the protection of escape routes, detection and extraction of smoke, use of sprinkler systems, warning systems, emergency electricity supply and other requirements according to type of occupancy.
