Which of the following can increase the possibility of electric shock when using the arc welding process?

• A. Working in confined spaces
• B. Working with high, open circuit voltage
• C. Working in the rain
• D. All of the above

Answer: (D)

Electric shock risk in arc welding rises when there is a greater path for current to flow through a person. High open-circuit voltage increases the potential difference that can drive current through the body if a conductive path is present. Working in a confined space can amplify danger because moisture, contaminants, and limited ventilation may accumulate, and it’s harder to quickly move away from energized parts. Wet conditions, like rain, dramatically lower skin resistance and provide an easy path for current to reach the welder. When any of these factors are present, the chance of a shock goes up; together they make the risk even higher. That’s why all of the above can increase the possibility of electric shock.
