For Site Management Level: (Monitor by Site Agent/ Safety Officer)

The issue of protection against electrocution should put into the agenda for discussion

amongst the site management, subcontractors representatives and frontline

supervisory staff in the Site Safety & Environmental Committee meeting.

For Frontline Supervisor Level: (Monitor by Site Agent/ Safety Officer)

Provide specific training on Electrical Safety on Construction Sites to the frontline

supervisors to enhance their knowledge of electrical safety.

All frontline supervisors will be instructed to enhance the site supervision and

monitoring on their responsible works areas to ensure that the electrical safety

precautions are strictly followed.

For Workers Level: (Monitor by Safety Officer/Frontline Foreman/Safety Supervisor)

Safety Officer and frontline foremen will brief the workers of Work Safety Alert

Electrical Safety on Construction Sites and the relevant publicity materials issued by

Ongoing Action

General

a) The Code of Practice (COP) for the Electricity (Wiring) Regulations and the Code of Practices (COP) onWorking near Electricity Supply Lines provide practical guidance and are relevant to this operational

control procedure. The guidance given in bothCOPs shall be observed when electrical works are

involved or carrying out works near electricity supply lines.

b) The design of electrical systems (both temporary and permanent) shall meet the statutory requirements.

c) All electrical installations shall be carried out by a Registered Electrical Worker of the appropriate grade

under the Electricity Ordinance in accordance with the design specification

d) All electrical systems shall be clearly marked to enable accurate identification:-

All electrical appliances and outlets shall be clearly marked to indicate their

purpose and voltage.

When the layout of an installation cannot be clearly distinguished, the circuits

and appliances shall be identified by labels or other effective means.

Circuits and appliances carrying different voltages in the same installation shall

be clearly distinguished by conspicuous means such as coloured markings.

Voltage of 110V should be used for portable and hand-held tools.

Notice on treatment for electric shock, in the Chinese and English languages, shall be displayed in

switchboard and distribution board where electricity in use.

e) If works are to be carried out under unfavourable site conditions, such as wet environment, ceiling voids

or situations with earthed structures/fittings in the close vicinity, a comprehensive risk assessment shouldbe conducted by a competent person. A permit-to-work system should be adopted with appropriate

safety precautions devised and implemented to eliminate or properly control the electrical hazards

involved.

g) Suitable personal protective equipment, such as insulating gloves and mat, should be provided for use if

necessary.

Switchboard

a) The Switchboards are installed, maintained and regularly checked by Registered Electrical Workers at

least once per month.

b) The connections of equipment and tools to the distribution board are carried out by Registered Electrical

Workers.

c) All Switchboards shall be maintained in accessible locations kept free from obstructions.

d) All Switchboards shall be fitted with signs detailing the electrical hazard and the supply voltage, contact

details of Registered Electrical Works, electrical wiring diagrams and notice for treatment of electric

shock in Chinese and English.

e) Distribution boards shall be lockable and it is necessary to ensure the distribution boards remain locked

when use.

f) The Switchboards shall be reactivated only by the Registered Electrical Worker.

3. All electrical equipment shall be inspected before it is taken into use and steps

taken to ensure that it is suitable for its proposed use.

Training and Promotion

Regular safey training/ tool box talk training on electricity safety and more promotion posters and

safety information on Safe Use of Electricity will be displayed on site to arouse the safety awareness

of the workers.

Display Guidebooks, Leaflets, Safety Alert, Newspaper cutting and Regulations (Cap 406) on safety

bulletin boards/ within site area.
