Every work activity, including operation, use and maintenance of a system and work near a system, shall be carried out in such a manner as not to give rise, so far as is reasonably practicable, to danger.

(4)

Any equipment provided under these Regulations for the purpose of protecting persons at work on or near electrical equipment shall be suitable for the use for which it is provided, be maintained in a condition suitable for that use, and be properly used.

Strength and capability of electrical equipment5.

No electrical equipment shall be put into use where its strength and capability may be exceeded in such a way as may give rise to danger.

Adverse or hazardous environments6.

Electrical equipment which may reasonably foreseeably be exposed to–

(a)

mechanical damage;

(b)

the effects of the weather, natural hazards, temperature or pressure;

(c)

the effects of wet, dirty, dusty or corrosive conditions; or

(d)

any flammable or explosive substance, including dusts, vapours or gases,

shall be of such construction or as necessary protected as to prevent, so far as is reasonably practicable, danger arising from such exposure.

Insulation, protection and placing of conductors7.

All conductors in a system which may give rise to danger shall either–

(a)

be suitably covered with insulating material and as necessary protected so as to prevent, so far as is reasonably practicable, danger; or

(b)

have such precautions taken in respect of them (including, where appropriate, their being suitably placed) as will prevent, so far as is reasonably practicable, danger.

Earthing or other suitable precautions8.

Precautions shall be taken, either by earthing or by other suitable means, to prevent danger arising when any conductor (other than a circuit conductor) which may reasonably foreseeably become charged as a result of either the use of a system, or a fault in a system, becomes so charged; and, for the purposes of ensuring compliance with this regulation, a conductor shall be regarded as earthed when it is connected to the general mass of earth by conductors of sufficient strength and current-carrying capability to discharge electrical energy to earth.

Integrity of referenced conductors9.

If a circuit conductor is connected to earth or to any other reference point, nothing which might reasonably be expected to give rise to danger by breaking the electrical continuity or introducing high impedance shall be placed in that conductor unless suitable precautions are taken to prevent that danger.

Connections10.

Where necessary to prevent danger, every joint and connection in a system shall be mechanically and electrically suitable for use.

Means for protecting from excess of current11.

Efficient means, suitably located, shall be provided for protecting from excess of current every part of a system as may be necessary to prevent danger.

Means for cutting off the supply and for isolation12.

(1)

Subject to paragraph (3), where necessary to prevent danger, suitable means (including, where appropriate, methods of identifying circuits) shall be available for–

(a)

cutting off the supply of electrical energy to any electrical equipment; and

(b)

the isolation of any electrical equipment.

(2)

In paragraph (1), “isolation” means the disconnection and separation of the electrical equipment from every source of electrical energy in such a way that this disconnection and separation is secure.

(3)

Paragraph (1) shall not apply to electrical equipment which is itself a source of electrical energy but, in such a case as is necessary, precautions shall be taken to prevent, so far as is reasonably practicable, danger.

Precautions for work on equipment made dead13.

Adequate precautions shall be taken to prevent electrical equipment, which has been made dead in order to prevent danger while work is carried out on or near that equipment, from becoming electrically charged during that work if danger may thereby arise.

Work on or near live conductors14.

No person shall be engaged in any work activity on or so near any live conductor (other than one suitably covered with insulating material so as to prevent danger) that danger may arise unless–

(a)

it is unreasonable in all the circumstances for it to be dead; and

(b)

it is reasonable in all the circumstances for him to be at work on or near it while it is live; and

(c)

suitable precautions (including where necessary the provision of suitable protective equipment) are taken to prevent injury.

Working space, access and lighting15.

For the purposes of enabling injury to be prevented, adequate working space, adequate means of access, and adequate lighting shall be provided at all electrical equipment on which or near which work is being done in circumstances which may give rise to danger.

Persons to be competent to prevent danger and injury16.

No person shall be engaged in any work activity where technical knowledge or experience is necessary to prevent danger or, where appropriate, injury, unless he possesses such knowledge or experience, or is under such degree of supervision as may be appropriate having regard to the nature of the work.

impose requirements with regard to the use of film lighting circuits below ground in coal mines (regulation 17(1) andSchedule 1);

(q)

impose conditions with regard to the introduction of specified electrical equipment into underground parts of specified safety-lamp mines (regulation 18);

(r)

impose requirements with regard to the preparation of plans identifying zones underground in safety-lamp mines where firedamp is likely to occur in quantities sufficient to indicate danger (regulation 19(1)) and specify that only certain electrical equipment may be energised in those zones and deem any lights which may be energised in such zones to be “permitted lights” as defined by section 182(1) of the Mines and Quarries Act 1954 (regulation 19(2)). Among the electrical equipment which may be energised in such zones is that which has been certified in accordance with Council Directive 82/130/EEC (OJ No. L59, 2.3.82, p.10) (which relates to the approximation of the laws of the Member States concerning electrical equipment for use in potentially explosive atmospheres in mines susceptible to firedamp), as adapted to technical progress by Commission Directive 88/35/EEC (OJ No. L64, 10.3.88, p.36);

(s)

impose requirements with regard to cutting off the supply of electricity to electrical equipment (or making it safe) when firedamp is found in concentrations exceeding 1.25% by volume in the general body of the air either below ground at, or at specified places on the surface of, mines (regulation 20);

(t)

impose restrictions with regard to the taking or use below ground at safety-lamp mines of electric safety-lamps, gas detectors, telephone and signalling equipment and other equipment associated therewith or required for the safety of persons (regulation 21);

(u)

impose requirements with regard to the provision and operation of switchgear in respect of electrical equipment which may give rise to danger and which is installed below ground at a mine, but which is supplied from a power source at the surface (regulation 22);

(v)

impose a prohibition on the introduction below ground at mines of electrical equipment using oil as a means of cooling, insulation or arc suppression (regulation 23);

(w)

impose requirements with regard to the preparation, keeping and display of schematic diagrams and plans of electrical distribution systems and permanently installed electrical equipment at mines (regulation 24);

(x)

(in circumstances where, at any place at a mine, electric arc welding is taking place or electrical energy is being generated, transformed or used at a nominal voltage in excess of 125 volts a.c. or 250 volts d.c.) impose requirements with regard to the display of notices giving information on the appropriate first-aid treatment for electric shock and details of what emergency action should be taken in the event of electric shock (regulation 25);

(y)

impose restrictions with regard to the introduction below ground at safety-lamp mines of locomotives and vehicles which use electrical storage batteries, either partly or wholly, as a power source (regulation 26);

(z)

impose requirements with regard to the use below ground at mines of electrical storage batteries (regulation 27).

The Regulations disapply section 157 of the Mines and Quarries Act 1954 (defence in certain legal proceedings) in relation to any legal proceedings or prosecutions arising out of regulations 18 to 27 and Schedule 1 (regulation 28) and provide a defence in the case of a contravention of certain of the Regulations (regulation 29). The Regulations provide for the issue of certificates of exemption by the Health and Safety Executive (regulation 30). The Regulations also provide that they shall apply outside Great Britain to the extent specified in regulation 31.

The Regulations revoke the instruments specified in Part I of Schedule 2 (regulation 33(1)), modify the enactments and instruments specified in Part II of Schedule 2 (regulation 33(2)) and provide that any reference to the Mines and Quarries Act 1954, the Mines and Quarries (Tips) Act 1969 or the Mines Management Act 1971 in any of those Acts, in regulations made under any of those Acts, or in health and safety regulations, shall be treated as including a reference to these Regulations (regulation 33(3)).
