141   Fire protection for certain above-ground tanks

(1)  In relation to premises in respect of which a person is required by AS 1940 to provide fixed foam systems for above-ground tanks, the provisions of:

(a)  subclauses (2)–(11), and

(b)  such of the provisions of sections 9 and 10 of AS 1940 as are not at variance with those subclauses,

      must be observed.

Contravention of this subclause is an offence and is punishable in accordance with clause 340.

(2)  Subject to subclause (3), a fixed foam protection system for extinguishing fires must be installed on every depot that:

(a)  is a fixed roof tank or a floating roof tank, and

(b)  has a diameter greater than 6 metres.

(3)  Subclause (2) does not apply to or in respect of a tank containing dangerous goods of Class C1 or C2 (combustible liquids) if it is not situated in the area within the bund wall surrounding a tank or tanks for the keeping of flammable liquid.

(4)  The fixed foam protection system installed on a floating roof tank must be capable of covering the circumferential seal of the tank with foam in not more than 2 minutes.

(5)  A suitable fitting must be provided for the supply of water into the foam protection system by means of a pump operated by the New South Wales Fire Brigades or other community fire-fighting service (the system must be so designed that it will continue to provide the requisite quantities of foam while the pump is connected to the system despite any failure of any pump that is a permanent part of the system).

(6)  Permanent pipe lines, galvanised and, if practicable, laid above ground, and fitted with suitable valves, must be provided for the supply of foam to the tanks from a control point.

(7)  All horizontal foam pipe lines of the system must be adequately flushed with water at intervals not longer than 6 months and means for carrying out such flushing must be provided.

(8)  All the horizontal foam pipe lines must be hydrostatically pressure-tested at twice the normal operating pressure at intervals not longer than 2 years.

(9)  The system must be tested by the use of foam at intervals not longer than 12 months.

(10)  A record must be kept of every test carried out under subclauses (8) and (9) and of every flushing carried out under subclause (7) and the records must:

(a)  be kept at the depot for a period of at least 5 years, and

(b)  whenever an inspector within that period so requires, be produced for his or her examination.

(11)  Dangerous goods must not be placed in a tank until the foam protection installation of the tank has been tested and passed by an inspector for compliance with this Regulation.
