Where it has been agreed to de-energise the line, pipe or electrical installation, whether underground or not, the employer shall ask the operator to de-energise the line, pipe or electrical installation.
After obtaining the operator’s written agreement, the employer shall set the dates on which the work may be carried out and the starting and finishing times for each day. These instructions, which are useful for organising the work, do not exempt the operator from drawing up and submitting the de-energisation certificate and the notice of cessation of work.
