17. Location of switchboard apparatus
All apparatus and equipment used in or in connexion with a switchboard and requiring handling shall be located and installed so that so far as is reasonably practicable— (71 of 1989 s. 13)
(a) such apparatus and equipment can be readily operated from floor level or from a working platform provided for that purpose;
(b) all measuring instruments and indicators used in or in connexion therewith can be readily observed from floor level or from the working platform;
(c) any such apparatus, equipment, measuring instrument or indicator that cannot be readily operated or observed from floor level or from a working platform, can be otherwise operated or observed without electrical hazard.

18. Precautions to be taken against metal becoming live
Where necessary to prevent electrical hazard adequate precautions shall be taken either by earthing or other suitable means to prevent any metalwork, other than the current-carrying conductors, enclosing or supporting any such conductors, from becoming live.

19. Precautions to be taken when persons are working on apparatus
(1) When work has to be carried out on any conductor, apparatus or switchboard adequate precautions shall be taken, including the prevention of any conductor or apparatus becoming accidentally live, so as to ensure that the work may be carried without undue risk from electrical hazard.
(2) A notice in red characters and letters each not less than 50 mm high on a white background reading “危險——在修理中 DANGER UNDER REPAIR” shall be placed and displayed in a visible position at, on or near any conductor apparatus or switchboard being worked on under paragraph (1).

20. Provision of protective stands or screens
Where necessary as a protection against electrical hazard, adequate insulating stands and screens or other protective equipment shall be provided and maintained in good condition and kept permanently in position.

21. Provision and use of protective stands, screens, boots and gloves
(1) Portable insulating stands, screens, mats and covers and insulating boots, gloves or other protective equipment shall be provided and maintained in good condition for use where necessary as a protection against electrical hazard.
(2) Every person working on apparatus shall make proper use of any equipment provided under paragraph (1).

22. Provision of access to and working space for apparatus
All apparatus which, in normal use, requires operation or attention by any person shall be installed so that adequate access and working space are afforded for its operation and attention, without electrical hazard.

23. Lighting of apparatus
Where necessary as a precaution against electrical hazard, adequate lighting shall be provided in all parts of the premises where apparatus which, in normal use, requires operation or attention by any person is installed.

24. Precautions for special conditions
All apparatus and conductors—
(a) exposed to weather, water, corrosive atmospheres or other adverse conditions;
(b) exposed to flammable surroundings or explosive atmosphere; or
(c) used in any process or for any special purpose other than for lighting or power,
shall be so constructed, installed and protected as may in the circumstances of such exposure or use be necessary to prevent electrical hazard or other danger.

25. Precaution for apparatus utilizing high voltage
Where necessary as a precaution against electrical hazard all apparatus operating at high voltage, shall have placed and displayed in a visible position at, on or near such apparatus a notice in red characters and letters each not less than 50 mm high on a white background reading “危險——高壓電力 DANGER HIGH VOLTAGE”.

26. Qualifications and supervision of persons carrying out work
(1) Subject to paragraph (2) no person except an authorized person shall carry out or assist in the carrying out of any work on any apparatus where technical or practical knowledge or experience is required in order to avoid electrical hazard.
(2) Notwithstanding paragraph (1) a competent person under the immediate supervision of an authorized person may carry out or assist in such work if—
(a) in the case where the electrical hazard to be avoided is under the control of an electrical contractor, he is appointed by the electrical contractor; and
(b) in the case where the electrical hazard to be avoided is under the control of the proprietor, he is appointed by the proprietor.
