RE: Substation Warning Signs
There must be a warning sign at each entrance and on each side of the fence.
Because of a court case a few years, the wording typically used is "Danger - High Voltage - Keep Out".
Many previous signs did not include the phrase "Keep Out". A utility lost a lawsuit after a teenage boy was electrocuted (after climbing the fence) because the warning sign did not say explicity "Keep Out". Go figure.
Good luck.

RE: Substation Warning Signs
I see that ANSI has a number of point documents under Z535
Z535.1-1998 on Color Codes
Z535.2-1998 on Safety Signs
Z535.3-1998 on Safety Symbols
Z535.4-1998 on Product Safety Labels and Signs
Has anyone needed more than just Z535.4 to stay in compliance and to exercise "highest degree of care."
Thanks,

In the NEC, there is also reference to NFPA 70E-2000, Standard for Electrical Safety Requirements for Employee Workplaces.

A safety sign shall be displayed at each entrances. For fenced electric supply stations, a safety
sign shall be displayed on each side.

Z535.5-1998 contain information regarding safety signs.
