Supervisor should closely monitor the activity, if he finds any operative is lagging on safe work competency, he will be sent for re-induction and even retraining if deemed necessary.

Examine the areas to execute the work and the conditions under which the work will be performed. Identify conditions detrimental or unsafe for the proper and timely completion of the Work.

Do not proceed until unsatisfactory or unsafe conditions have been corrected.

Working on live power cables/equipment is not allowed.

ELCB will be used in temporary panel boards; industrial connectors/sockets to be used for temporary power cable connections.

Always maintain cleanliness in work areas.

Housekeeping will be of good standard and all cut pieces and debris will be removed by the end of workday.

All scaffoldings will be checked by competent person and should carry green tags “safe to use”, prior to use for working purpose.

Operatives working at height to wear their full body harness and should be anchored to a rigid point.

Nobody is allowed to stand on the top of the step ladder; worker should stand two rungs below from top of the step ladder. A co-worker must hold the step ladder while in use.

Work inside shafts are not allowed without work permit and supervision.

All the work areas to be provided with proper lighting and ventilation at all times.
