What do the terms step potential and touch potential refer to?

• A. Hazards associated with chemical spills
• B. Safety equipment design
• C. Dangers associated with voltage gradients
• D. Mechanical failure of equipment

Answer: (C)

The terms step potential and touch potential refer specifically to dangers associated with voltage gradients. These concepts are crucial in understanding electrical safety, particularly in the context of mining and other industrial settings. Step potential is the voltage difference that a person experiences when they are standing on the ground and one foot is at a different potential than the other. This can occur when there is a fault in an electrical system, causing the earth's surface to become energized. If a person were to step from one potential to another, the difference can create a dangerous electric shock. Touch potential, on the other hand, is the voltage difference between an energized object and the ground, which can also pose a risk of electric shock if someone touches that object while standing on the ground. Recognizing these dangers is essential for implementing proper safety measures, as electrical hazards can lead to serious injuries or fatalities in a mining environment. Understanding step and touch potentials allows shift bosses and other mine personnel to establish safety protocols and utilize protective equipment effectively, ensuring a safer working environment for all employees.
