What is the maximum voltage allowed on bare signal wires accessible to persons?

The maximum voltage allowed on bare signal wires that are accessible to persons is established to ensure safety and minimize the risk of electrical shock. A voltage level of 48 volts is deemed safe under most electrical safety standards because it reduces the likelihood of serious injury in the event of accidental contact.

At voltages higher than this threshold, the risk of electric shock increases significantly, as well as the potential for more severe consequences if contact occurs. The standard helps to protect individuals who may come into contact with these wires during their work or routine activities.

This safety measure is crucial in mining operations and other industrial settings where workers are frequently near electrical equipment and wiring, emphasizing the need for maintaining safe environments in places where electrical hazards may exist.
