What is a key measure against electrical hazards in pipefitting?

Ensuring all tools and machinery are properly grounded is a crucial measure against electrical hazards in pipefitting because proper grounding provides a safe path for electrical current. In the event of a fault or malfunction, grounding helps to prevent the buildup of voltage that could potentially lead to electric shock or equipment damage. By connecting electrical equipment to the ground, any stray electrical current can flow safely away, reducing the risk of injury to the worker and enhancing overall safety in the workplace.

Improper use of extension cords, such as favoring them over proper wiring, can lead to unsafe conditions, including increased risk of overload and potential hazards from damaged cords. Minimizing the number of electrical tools could reduce exposure to risks, but it does not address the core electrical safety measures required for safe operation. Working only during daytime hours offers limited benefits in addressing electrical hazards, as many risks remain regardless of lighting conditions. Proper grounding stands out as the most effective safety practice, minimizing the risks of electrical hazards in pipefitting situations.
