Which statement best describes safe use of extension cords in the shop?

• A. Always run under rugs
• B. Never use near water
• C. Never use with heavy equipment
• D. Only use outside

Answer: (B)

Keeping extension cords dry is essential because water conducts electricity and greatly raises the risk of shock or electrocution in a shop where liquids and damaged insulation are common. When moisture is present, even a cord that seems intact can become hazardous, as a spill or splash can create a conductive path to you or to grounded surfaces. That’s why the safest practice is to avoid using cords near any water or damp areas. Other cautions matter too—like not running cords under rugs (which can hide damage and trap heat) and using cords that are properly rated for the load and environment—but moisture proximity is the most direct and universal safety concern in a shop.
