What must be done to resist electrical shock while working?

• A. Use insulating tools and wear rubber soles
• B. Work only during daylight hours
• C. Wear a hard hat at all times
• D. Use metal tools for grounding

Answer: (A)

Using insulating tools and wearing rubber soles is essential for resisting electrical shock while working. Insulating tools are specifically designed to prevent electrical current from passing through the user, thereby reducing the risk of shock. These tools often have non-conductive materials that protect the user from inadvertently coming into contact with live electrical components.

Similarly, wearing rubber-soled shoes contributes to the overall safety by acting as an additional layer of insulation between the worker and the ground. Rubber is a poor conductor of electricity, which helps to prevent the flow of electric current through the body in case of accidental contact with live wires or equipment.

The other options do not provide effective measures for preventing electrical shock. Working only during daylight hours does not eliminate the risk of electrical hazards, as many electrical tasks can be performed indoors or in well-lit locations where the risk remains. Wearing a hard hat, while important for protection against falling objects, does not address the specific risk posed by electrical shock. Using metal tools for grounding is also hazardous; metal is a conductor that can facilitate the flow of electrical current, instead of providing protection.
