The manual must include the procedure of taking line clearance (LC) & LC returns. –District administration need to ensure electrical safety clearance certificates on every temporary connection given to Melas, Yatras, Exhibitions etc. (The accident like Madhuban (Baripada) fire hazards & fatalities may not be repeated) –All the utilities shall be advised to prepare a safety manual for their activities and specify the functions and responsibilities of each category of involved personnel / Officers. The safety office of the utilities has the responsibilities to oversee to the adherence of the duties / functions. –Avoid misuses of danger board / danger notice. Use in the appropriate places to create the potentially of electricity danger.
