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.
A pneumatic system can utilize a pressure relief valve or an emergency stop valve to assist in a safe stop during a power outage. These components help to release trapped air and prevent sudden movement of actuators, ensuring a controlled stop. Additionally, incorporating accumulators can store energy, allowing for a safe and gradual cessation of operation. This ensures the safety of personnel and equipment during unexpected power loss.
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.

The maximum safe distance to a UXO for exposed personnel is typically considered to be at least 500 feet. It is important to quickly evacuate the area and alert authorities if a UXO is detected to minimize the risk of injury.
No, it is not safe to touch exposed electrical wire as it can cause electric shock or injury. It is important to keep a safe distance and contact a professional for assistance.

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.
