What are the specific requirements for fire separation between attached dwellings under NCC 2022 in Tasmania?

Under NCC 2022, Tasmania, fire separation between attached dwellings, classified as Class 1a buildings, typically requires a fire-resisting wall extending to the underside of the roof covering or to the outer edge of the eaves, subject to specific construction types and external wall setbacks. This wall must achieve a minimum FRL (Fire Resistance Level) of 60/60/60. Furthermore, openings in these walls are restricted, and specific details for penetration sealing and integrity are mandated to prevent fire spread. Compliance with Volume Two's D2D2 and D2D3 provisions is critical, considering Tasmania's specific deemed-to-satisfy requirements.
