What are the basic rules regarding substation safety?

There are six basic rules for substation safety. These are as follows:

Rule no. 1 (regarding clearance):

Enough clearance from energized parts should be provided to avoid accidental contact with them. If it is not possible live parts should be enclosed.

Rule no. 2 (Regarding minimum height):

A minimum height from the ground to any ungrounded part of an electrical installation should be 8’-6”. For this a person staying on the ground can’t touch a substation element or its part which may become energized accidentally. 

Rule no. 3 (Regarding illumination):

There should be sufficient illumination for personnel to clearly see their surroundings and perform any work safely. 

Rule no. 4 (Regarding passageways):

All passageways and stairs should be wide enough for personnel to navigate them safely, adequate railing should be provided, and floor openings should have guard rails. Also have to a emergency door for exit easily in any emergency case.

Rule no. 5 (Regarding evacuation routes):

Exits should be clearly marked and evacuation routes should be free from obstructions. 

Rule no. 6 (Regarding grounding):

All substation metallic structures, fences, and equipment tanks should be connected to a station ground grid which will ensure no chance of electric shock.
