Which of the following is NOT listed as a method of ensuring an electrically safe work condition?

Barricading is not typically recognized as a direct method of ensuring an electrically safe work condition. It mainly serves as a physical barrier to restrict access to unsafe areas but does not specifically address the electrical hazards inherent in working with electrical equipment or systems.

In contrast, insulated tools are designed to protect the user from electric shock while working on or around energized circuits. Grounding provides a safe path for electrical currents in case of a fault, preventing potential shock and fire hazards. Lockout/tagout is a critical safety procedure used to ensure that machines and equipment are properly shut off and unable to be started up again before maintenance or servicing is completed, thereby protecting workers from unintended energization.

Thus, while barricading can play a role in overall safety by keeping personnel out of hazardous areas, it does not provide the specific protections necessary to manage electrical shocks or other electrical risks effectively.
