(1) In this clause:
lay, in relation to a pipeline, means to lay or otherwise install the pipeline.
pipeline means a pipeline for the conveyance of combustible liquids or other dangerous goods (not being dangerous goods of Class 2), being a pipeline that:(a) passes over, under or through a public place, or(b) passes from premises occupied by one person to premises occupied by another person.(2) A person must not, except with the approval in writing of the WorkCover Authority, lay a pipeline, relay or renew a pipeline in whole or in part or effect repairs to a pipeline (other than minor repairs incidental to its ordinary maintenance).(3) An application for an approval must be accompanied by:(a) full details of the proposed pipeline or the proposed relaying, renewing or repairs, and(b) if the application is in relation to the laying, relaying or renewing of a pipeline underground or partly underground—data in relation to the corrosive tendencies and other relevant characteristics of the soil through which the pipeline is to pass.(4) A person must not use a pipeline that has, after the commencement of this Regulation, been laid, or relaid or renewed in whole or in part, or to which any repairs (other than minor repairs incidental to its ordinary maintenance) have been effected, until approval in writing to the use of the pipeline is given by the WorkCover Authority.(5) The WorkCover Authority may by order require the owner of a pipeline to relay or to renew it in whole or in part, in accordance with requirements and within a time specified in the order, and the owner must comply with the order or cease to use the pipeline.(6) A person must not use a pipeline if it or any of its equipment does not conform to this clause or if it has not been tested, examined and maintained in accordance with this clause.(7) A pipeline must:(a) to such extent as is practicable, be above ground, and(b) if it is above ground, be securely supported to a height of not less than 150 millimetres above the ground, but so that it does not rest directly on wood, and(c) be securely fixed in position.(8) A pipeline must be designed, constructed, tested and maintained in accordance with AS 4041 (Pressure piping), AS 2885 (Pipelines—Gas and liquid petroleum) and any other approved standard or code, or(9) A pipeline must:(a) be in such a position that it will not be exposed to unnecessary risk of mechanical injury, and(b) at any place where it is laid under a highway, road, street, thoroughfare, railway or tramway, or in any other place where it will or may be subjected to heavy loads through the passage of vehicles or other traffic:(i) be protected in accordance with the Code numbered 1102 and entitled “Steel Pipelines Crossing Railroads and Highways” of the American Petroleum Institute (only in the case of pipelines laid after the commencement of this Regulation) or, in an approved manner, by the provision of sleeves or culverts (or other approved means), and(ii) have above the level of the top of the pipeline (the level of flanges being disregarded) at any such place approved material at least 600 millimetres in depth, and(iii) be provided with access pits, with covers, that will provide convenient access to all its valves, and(iv) have provision for convenient access to all its joints, and(c) if laid underground or under water, be provided with cathodic protection in accordance with AS 1697 (SAA gas pipeline code), AS 2832 (Guide to the cathodic protection of metals), Part 1 (Pipes and cables) or any approved standard or code, and(d) be further protected in such manner as the WorkCover Authority may require.(10) Lengths of piping that form a pipeline must:(a) if practicable, be joined together by welding, or(b) if joining by welding is not practicable, be joined together by means of flanged ends or by approved means.(11) Gate valves of the rising spindle type, of cast steel or other appropriate material and fitted with right-hand threads, or other approved valves must be installed at the control points of a pipeline.(12) A pipeline must:(a) be bonded and earthed in an approved manner along the whole of its length, and(b) have a resistance to earth not exceeding 10 ohms, and(c) be tested for resistance to earth at intervals of not more than 12 months.(13) A pipeline and its control valves must be marked in such manner as the WorkCover Authority may require.(14) After the laying, relaying or renewal of a pipeline, the pipeline must not be used until:(a) it and its fittings have been tested in sections along its whole length with water to a pressure of 2 000 kilopascals or 1.5 times its maximum anticipated working pressure, whichever is the greater, that pressure being maintained for a period of not less than 30 minutes, and(b) the tests referred to in paragraph (a) have shown it to be free of leaks.(15) At least once every 2 years a pipeline must be tested in accordance with subclause (14) (a) and it must not be used unless and until the tests show that it is free of leaks.(16) At least once every 5 years a pipeline must be examined at points not greater than 150 metres apart along its whole length by a competent person and, if the examination discloses any defects, it must not be used until the defects have been rectified.(17) Subclauses (2), (4), (5), (7), (8) and (10)–(16) do not apply to or in respect of a flexible hose that is, or is part of, a pipeline.(18) A flexible hose that is, or is part of, a pipeline must:(a) be of approved materials and manufacture, and(b) if the hose is used for the conveyance of combustible liquids or dangerous goods of Class 3 or subsidiary risk 3—comply with BS 1435: Part 2: 1989 (Rubber hose assemblies for oil suction and discharge services) published by the British Standards Institution, and(c) have a safe working pressure of at least 700 kilopascals, and(d) be fitted with “Turk’s heads” of hemp or sisal rope, or other approved means of protection, at intervals of one metre, and(e) have marked on it, by means of an engraved metal plate forming part of the hose or by approved means, an identification number for the hose, its maximum safe working pressure and the name of its owner, and(f) be so supported as to prevent chafing and kinking when liquid is being pumped through it, and(g) be tested at least once every 6 months, in accordance with its normal manner of use, to a pressure at least 25 per cent in excess of the maximum pressure under which it is operated when in use.(19) All electrical equipment used in connection with a pipeline must conform to AS 3000 (SAA Wiring Rules).(20) A person must not:(a) if the pumping of combustible liquids or dangerous goods of Class 3 or subsidiary risk 3 through a pipeline has commenced, or is resumed after water has been used to clear it in preparation for a change of the kind of goods pumped—for the first 20 minutes, or for a time sufficient to enable a volume of liquid equal to its capacity to pass through it twice, whichever is the longer, or(b) if any dangerous goods are being pumped through a pipeline into an empty tank—until the fill pipe of the tank, if it is a cone roof tank, is covered or until the roof of the tank, if it is a floating roof tank, is afloat,pump goods through the pipeline in such a manner that the velocity of the goods at any part of the pipeline exceeds one metre per second.(21) A person must not pump goods through a flexible hose that is, or is part of, a pipeline in such a manner that, immediately before the hose is disconnected, the pressure within it exceeds 200 kilopascals absolute.(22) The owner of a pipeline must at all times:(a) maintain it in good order and condition, and(b) take all practicable precautions to prevent the escape of any liquid or vapour from it.(23) A person must not use a pipeline on any occasion unless immediately before its use on that occasion the valves and other appurtenances to be used in the pumping of goods through it have been tested by a competent person and found to be operating in a safe and efficient manner.(24) A person must not use or test a pipeline unless the whole of it is kept under such surveillance as will ensure that any leakage of liquid or vapour that may occur during the use or testing will be promptly detected.(25) The owner of a pipeline must:(a) keep, and retain for at least 5 years, a record of all tests and examinations of the pipeline made under subclauses (14)–(16), and(b) whenever required by an inspector at a reasonable time, produce it for examination or copying by the inspector.(26) If there is a risk of a leak through a flange or any other part of a pipeline and any such leak might cause damage to the environment or property or injury to persons, the point of the potential leakage must be protected so as to minimise any adverse consequences.
Contravention of this clause is an offence and is punishable in accordance with clause 340.
