Which method is NOT recommended for preventing electric shock?

• A. Using electrically rated rubber gloves
• B. De-energizing equipment
• C. Using battery-powered tools
• D. Employing corded tools while working

Answer: (D)

Using corded tools while working is not recommended for preventing electric shock because corded tools are directly connected to the electrical supply, which poses a risk of electric shock if the tool becomes damaged or if there is a fault in the electrical system. In contrast, the other options present methods that enhance safety while working with electrical equipment.

Using electrically rated rubber gloves provides a protective barrier between the electrical source and the user. These gloves are designed to insulate against electric shock, making them a vital piece of personal protective equipment for anyone working with or near live electrical circuits.

De-energizing equipment is an essential safety practice that involves disconnecting electrical power from equipment before maintenance or repairs. This method significantly reduces the risk of electric shock since it eliminates the potential for electrical energy to flow through the equipment during work.

Battery-powered tools are an alternative that mitigates the risk of electric shock because they operate independently of the electrical supply, thus reducing exposure to electrical hazards associated with corded tools. This makes battery-powered options safer for certain tasks, especially in environments where the risk of wet or conductive materials is present.

By avoiding the use of corded tools, especially in potentially hazardous conditions, workers can better protect themselves from the dangers of electric shock.
