Location of tank Protective measures 1800 mm or more from a building No protection required Less than 1800 mm from any part of a building Any eaves less than 1800 mm from the tank should have 30 minutes fire resistance for integrity and insulation extending 300 mm beyond each side of the tank, and either (a) any part of the building wall less than 1800 mm from the tank should be imperforate with a minimum 30 minutes fire resistance in terms of insulation, integrity and stability to internal fire; or (b) provide a fire wall between the tank and any part of the building which is less than 1800 mm from the tank. The fire wall should extend not less than 300 mm higher and 300 mm wider than the tank. 750 mm or more from a boundary No protection required Less than 750 mm from a boundary Provide a fire wall between the tank and the boundary or a boundary wall, which has a minimum of 30 minutes fire resistance in terms of insulation, integrity and stability to fire on either side. The fire wall or fire resistant boundary wall must extend not less than 300 mm higher and 300 mm beyond the ends of the tank. Notes: Fire walls should be imperforate non-combustible walls or screens, such as a masonry wall or fire-rated composite panel screens.
