Discharge From Exits
The ‘discharge from exits’ are provisions in the Building Code of Australia to maintain a safe unobstructed path of travel from the ‘exit door’ of a building to a road or open space. Discharge from exits should always be nominated as an essential safety measure by the building surveyor/ building certifier.
Building Code of Australia
The Building Code of Australia (BCA) contains a number of provisions containing clauses relative to ‘discharge from exits’ i.e. D1.7, D1.9 to D1.11, D2.13, G4.3, G4.6 and G4.7. The BCA requires the discharge from exits path (egress) to be at least 1m wide (must be wider under certain conditions), open to the sky for its full length, installed with bollards to prevent vehicles obstructing and its surface to be sufficient to accept foot traffic under a building permit.
