When things deemed unsafe

11 General rules for when things deemed to be unsafe
  • (1) A distribution system, a gas installation, fitting, or a gas appliance is deemed to be unsafe if measures are not in place that—

    • (a) ensure a release of gas is detectable or ignition of release is prevented unless such a release is required to establish or sustain combustion; and

    • (b) ensure gas is not released in an uncontrolled manner; and

    • (c) ensure that any oxygen and gas is prevented from mixing in a pipe unless the mixture is outside the flammability limits; and

    • (d) ensure persons are not exposed to carbon monoxide and other harmful products of combustion of gas; and

    • (e) ensure persons and property are not exposed to excessive forces; and

    • (f) ensure that the failure of any control or safety device does not expose the downstream equipment to excessive pressure above the rated pressure of any distribution system and equipment downstream of that control or safety device; and

    • (g) enable the effective isolation and shut-off of the gas supply, including during an emergency.

    (2) A distribution system, a gas installation, fitting, or a gas appliance is also deemed to be unsafe if—

    • (a) the safety-related characteristics of any fittings are impaired so that the safety function is not served; or

    • (b) a joint between pipes, or between pipes and fittings, is inadequate, incompatible, or unreliable; or

    • (ba) the fittings in any distribution system, gas installation, or gas appliance—

      • (i) have a gas leakage (other than a minute leakage that is permissible under relevant testing procedures); or

      • (ii) are capable of being operated in a manner that is hazardous when the fittings are exposed to any reasonably foreseeable torques, pressures, or chemical or physical conditions; or

    • (c) the fittings of any gas installation, distribution system, or gas measurement system are exposed to a pressure exceeding their maximum rated pressure, including as a result of the failure of any control or safety device; or

    • (d) a pipe (whether above or below ground) is inadequately protected against the risk of damage or corrosion; or

    • (e) a pipe is subject to forces beyond its design criteria; or

    • (f) there is insufficient space, access, lighting, ventilation, or facilities to operate, maintain, test, and inspect any fittings required to be operated, maintained, tested, or inspected; or

    • (g) any fittings that cause or are subject to high temperatures are placed in a position, or are unprotected, so as to create a risk of ignition of flammable materials or a risk of injury to persons or damage to property.

    (3) Subclauses (1) and (2) do not limit the rest of these regulations.
