    What type of footwear best protects against electrical hazards in the workplace?

    • Rubber overshoes

    • Nonconductive safety shoes

    • Rubber-soled sneakers

    • Conductive safety shoes

    Correct Answer
    A. Nonconductive safety shoes
    Explanation
    Nonconductive safety shoes are the best type of footwear to protect against electrical hazards in the workplace. These shoes are designed with materials that do not conduct electricity, providing insulation and reducing the risk of electric shock. Rubber overshoes and rubber-soled sneakers may offer some level of protection, but they are not specifically designed to withstand electrical hazards. On the other hand, conductive safety shoes can actually increase the risk of electric shock by allowing electrical currents to pass through them. Therefore, nonconductive safety shoes are the most suitable choice for protecting against electrical hazards in the workplace.
