(a) welding and other hot-work; and

(b) cold-work (including physical isolation); and

(c) electrical work (including electrical isolation); and

(d) entry into, and working in, a confined space; and

(e) procedures for working over water.

(2)  If the safety management scheme for gas infrastructure specifies safety-critical work, the scheme must require the licensee responsible for the gas infrastructure to establish and maintain a permit-to-work system in respect of that work.

(3)  A permit-to-work system must –

(a) prohibit any person from performing safety-critical work or any activity in respect of such work without a written permit to work issued by a person authorised by the licensee to issue that permit; and

(b) specify by position the persons who are authorised to issue a permit to work and to supervise that work; and

(c) ensure that persons responsible for the issuing of permits to work and persons carrying out operations under a permit to work are competent and are provided with appropriate training, procedures, tools, equipment and emergency support.
