Substations may contain uninsulated high-voltage lines, busbars, and other equipment. Although this live equipment is mounted at a safe distance from trained personnel, those unaware of the hazards may approach the live equipment without realising that the voltages are high enough to break down the insulation of the air if they should approach within the safe distance limits, with lethal results.
I think 500 m is enough.
To keep the rig tirning right to ensure enough personnel and equipment are available at the right time. to keep the personnle from being hurt, keep the Well controlled and to keep the environment safe.
Technically, the intensity of the electromagnetic fields radiated from electrical transmission lines becomes smaller as the distance from the cable increases, but it never reaches zero. Despite many studies made on the effects of magnetic fields, there is no definitive guide as to what harmful effects high voltage fields have on humans or other living things. The level of risk in being exposed to these fields cannot be categorically stated.

Depends on may things, but 500 metres would be a mininum.

Expose the minimum number of personnel for a minimum amount of time to a minimum amount of explosives consistent with safe and efficient operations.

In Oregon there is no minimum thread depth, but just that Oregon requires that tires be in safe operating condition, without any bulges or exposed cords.

The external irradiation from depleted uranium is not significative.
Actually, 2 seconds is NOT a safe following distance. Minimum safe following distance is 5 seconds. Yes, it works at any legal speed in dry weather.
