Where any gas escapes from any pipe of a public gas supplier, or from any pipe or other gas fitting used by a person supplied with gas by a public gas supplier, the supplier shall, immediately after being informed of the escape, prevent the gas from escaping (whether by cutting off the supply of gas to any premises or otherwise).

If a public gas supplier fails within twelve hours from being so informed effectually to prevent the gas from escaping, he shall be guilty of an offence and liable on summary conviction to a fine not exceeding level 3 on the standard scale.

In any proceedings for an offence under sub-paragraph (2) above it shall be a defence for the public gas supplier to prove that it was not reasonably practicable for him effectually to prevent the gas from escaping within the said period of twelve hours, and that he did effectually prevent the escape as soon as it was reasonably practicable for him to do so.

Where a public gas supplier has reasonable cause to suspect that gas supplied by him is escaping, or may escape, in any premises, any officer authorised by the supplier may, on production of some duly authenticated document showing his authority, enter the premises, inspect the gas fittings, carry out any work necessary to prevent the escape and take any other steps necessary to avert danger to life or property.

Where a public gas supplier has reasonable cause to suspect that gas supplied or conveyed by him which has escaped has entered, or may enter any premises, any officer authorised by the supplier may on production of some duly authenticated document showing his authority, enter the premises and take any steps necessary to avert danger to life or property.
