List a basic electrical safety practice that should be observed in the workplace.

• A. Inspect cords only when suspicious.
• B. Use properly grounded equipment.
• C. Remove lockout during maintenance.
• D. Do not use protective covers.

Answer: (B)

Grounding provides a safe path for fault current to run into the earth, keeping metal parts at earth potential and reducing the chance that a person will become the path to ground. With properly grounded equipment, a fault quickly trips fuses or breakers, cutting the power before a severe shock or fire can occur. In practice, this means using outlets and tools with working grounding conductors and ensuring the equipment’s ground connection is intact and continuous. Other listed practices would leave workers more exposed—checking cords only when there is visible damage, bypassing lockout/tagout during maintenance, or using unprotected parts—so grounding is the most reliable, basic safety measure.
