“the 1974 Act” means the Health and Safety at Work etc. Act 1974;

[F1 “CDG 2007” means the Carriage of Dangerous Goods and Use of Transportable Pressure Equipment Regulations 2007];

“danger” in relation to a pressure system means reasonably foreseeable danger to persons from system failure, but (except in the case of steam) it does not mean danger from the hazardous characteristics of the relevant fluid other than from its pressure;

“examination” means a careful and critical scrutiny of a pressure system or part of a pressure system, in or out of service as appropriate, using suitable techniques, including testing where appropriate, to assess–

(a)

its actual condition; and

(b)

whether, for the period up to the next examination, it will not cause danger when properly used if normal maintenance is carried out, and for this purpose “normal maintenance” means such maintenance as it is reasonable to expect the user (in the case of an installed system) or owner (in the case of a mobile system) to ensure is carried out independently of any advice from the competent person making the examination;

(a)

a system comprising one or more pressure vessels of rigid construction, any associated pipework and protective devices;

(b)

the pipework with its protective devices to which a [F4 pressure receptacle, an old pressure receptacle or transportable pressure equipment] is, or is intended to be, connected; or

(c)

a pipeline and its protective devices,

which contains or is liable to contain a relevant fluid, but does not include a [F5 pressure receptacle, an old pressure receptacle or transportable pressure equipment];

“protective devices” means devices designed to protect the pressure system against system failure and devices designed to give warning that system failure might occur, and include bursting discs;

“relevant fluid” means—

“system failure” means the unintentional release of stored energy (other than from a pressure relief system) from a pressure system;

F6 ...

[F7 “transportable pressure equipment” has the same meaning as in regulation 2(1) of [F1 CDG 2007] except that it shall exclude a tank within the meaning of those Regulations;]

“user” in relation to a pressure system, or a vessel to which regulation 15 applies, means the employer or self-employed person who has control of the operation of the pressure system or such a vessel or, in the case of a pressure system or such a vessel at or in–
