What is the main safety measure to prevent electric shock?

Ensuring equipment is grounded is a crucial safety measure to prevent electric shock. Grounding provides a safe pathway for electrical currents to travel in case of a fault or malfunction. When equipment is properly grounded, any excess electricity can flow safely into the earth rather than through a person who may accidentally come into contact with the equipment. This significantly reduces the risk of severe injury or fatality from electric shock.

While using rubber gloves and other personal protective gear can help minimize risks, they are not foolproof methods. Rubber gloves can degrade over time, and relying solely on them does not address the potential hazards posed by ungrounded equipment. Grounding, on the other hand, is a fundamental safety principle in electrical work that protects everyone interacting with the equipment.

Limiting the number of workers may contribute to a safer work environment in certain contexts, but it does not address the core issue of electrical safety. Grounding is a proactive measure that addresses the inherent risks associated with electrical currents, making it the primary method for preventing electric shock.
