—(1) No person shall carry out any work in such a manner that allows gas to escape unless precautions are taken to prevent any such escape of gas from being a danger to any person or property.
(2) No person shall connect a gas installation to a source of gas without ensuring that every outlet is sealed with the appropriate gas fitting and the gas installation has been tested for gas tightness.
(3) Where a person carries out any work in relation to a gas fitting which might affect the gas tightness of a gas installation, a gas pipeline or gas pipeline network, he shall immediately thereafter test the system for gas tightness.
(4) Any person who disconnects a gas fitting shall, with the appropriate fitting, seal off every outlet of every pipe to which it is connected.
(5) No person carrying out work in relation to a gas fitting which involves exposing any part of the gas installation which contains or contained flammable gas shall smoke or use any source of ignition unless the gas installation has been purged so as to remove all such gas or has otherwise been made safe from risk of fire or explosion.
(6) No person searching for an escape of gas from a gas fitting shall use any source of ignition unless the source of ignition is incorporated as part of an instrument designed for the detection of gas.
(7) No person shall use any naked flame or carry out any hotwork in the vicinity where gas is known to be leaking.
(8) Any person who contravenes any provision of this section shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $50,000 or to imprisonment for a term not exceeding 5 years or to both and, in the case of a continuing offence, to a further fine not exceeding $250 for every day or part thereof during which the offence continues after conviction.
—(1) Where any gas escapes from any gas pipeline owned by, or under the management or control of a gas transporter, or from any internal pipe, gas fitting or gas appliance used by a consumer to whose premises gas is conveyed by the gas transporter, the gas transporter shall —
immediately take steps necessary to prevent the gas from escaping (whether by disconnecting any premises or otherwise); and
take any other steps necessary to avert danger to life or property.
(2) If a gas transporter —
fails within a reasonable time to effectively prevent the gas from escaping; or
fails to comply with subsection (1)(b),
he shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $100,000 and, in the case of a continuing offence, to a further fine not exceeding $10,000 for every day or part thereof during which the offence continues after conviction.
(3) In any proceedings for an offence under subsection (2)(a), it shall be a defence for the gas transporter to prove that —
it was not reasonably practicable for it to effectively prevent the gas from escaping; and
it did effectively prevent the escape as soon as it was reasonably practicable for him to do so.
(4) In any proceedings for an offence under subsection (2)(b), it shall be a defence for the gas transporter to prove that it took all such steps to avert danger to life or property as were reasonably practicable.
(5) It shall be the duty of any gas transporter, gas shipper or gas retailer to take all steps necessary to ensure that, if it is informed by any person (the informant) or otherwise knows of an escape of gas (other than one, in the case of a gas transporter, that it is required by subsection (1) to prevent), it passes the information on, without avoidable delay —
to a responsible person, that is to say, a person appearing to it —
to be responsible (whether under this section or otherwise) for preventing the escape; or
to be the gas transporter from whose gas pipeline network the gas is escaping; or
to a person nominated by a responsible person to receive information on his behalf about escaping of gas.
(6) For the purposes of subsection (5)(b), there shall be sufficient compliance if the gas transporter, gas shipper or gas retailer is reasonably satisfied that the informant has passed on the information, without avoidable delay, to the nominated person.
—(1) Where a gas transporter has reasonable cause to suspect that gas conveyed by him which has escaped, has entered, or may enter any premises, the gas transporter shall take all steps necessary to avert danger to life or property.
(2) If a gas transporter fails to comply with subsection (1), it shall be guilty of an offence and shall be liable on conviction to a fine not exceeding $100,000.
(3) In any proceedings for an offence under subsection (2), it shall be a defence for the gas transporter to prove that it took all such steps to avert danger to life or property as were reasonably practicable.
—(1) Where, on the occurrence of a fire or on the reasonable expectation or occurrence of an operational emergency, a gas transporter, a licensed gas service worker or an authorised officer is of the opinion that immediate action is necessary —
in the interests of public safety;
in order to repair damaged gas pipelines;
in order to avoid undue interference with the efficient conveyance of gas and shipping of gas to consumers;
for the construction of any new work, alteration to or the maintenance of any existing work;
for the installation, change or removal of any meter; or
for the conservation of the supply of gas,
the gas transporter or licensed gas service worker or authorised officer, as the case may be, may immediately disconnect or divert the supply of gas to any premises and shall immediately thereafter give notice in writing of the disconnection or diversion to the owner or occupier of the premises.
(2) A gas transporter, licensed gas service worker or authorised officer shall not be liable under this section in respect of any injury, loss or damage suffered by any person by reason of —
any failure to provide or delay in providing any supply of gas or any associated gas fitting or gas appliance; or
any failure, interruption, suspension or restriction of any supply of gas which has not been caused by the negligence of the gas transporter, licensed gas service worker or authorised officer, as the case may be.
68. A gas transporter may, for operational reasons without incurring any liability for so doing, reduce as it thinks fit the pressure of gas supplied in any case, if at any time it is of the opinion that its gas supply pressure is insufficient for the purposes of maintaining a normal supply of gas, and such pressure shall be restored as soon as reasonably practicable.
