Part 40 Utility Workers – Electrical

Explanation of Rules Referenced from the ECUC, Second Edition

Rule 4-016 Coordination

An employer must assign an operator-in-charge (OIC) for the entire power system or, if more than one OIC is required, assign an OIC for each portion of the system that that OIC is in control of. This serves to prevent any confusion as to who controls the operation of the electric utility system or each specific portion of the electric utility system. The employer must provide the OIC with sufficient information to allow the OIC to carry out his or her duties e.g. maps, logs, SCADA, switching diagrams, equipment information, etc.

The employer must provide written procedures to workers that describe the operation, isolation and maintenance of the power system. These procedures represent the general practices to be followed – they are not always a step-by-step procedure. The employer must also provide written procedures describing the safe installation and use of protective grounds.

Information about power system operation and grounding applications must be kept up-to-date and made available to the OIC and qualified utility employees. The OIC should be made aware of all changes to single line diagrams (paper or electronic), grounding, on the system and any operating procedures affecting the system as soon as practicable. The OIC needs this information to safely operate the system.
