Why is lockout/tagout important during RAWS maintenance?

• A. It provides a checklist for calibrations.
• B. It increases radio frequency exposure to protect antennas.
• C. It standardizes instrument naming.
• D. It prevents unexpected energization and RF exposure hazards during servicing.

Answer: (D)

Lockout/tagout protects workers by preventing unexpected energization during maintenance. In RAWS maintenance, there are electrical power sources and RF-transmitting equipment that can energize suddenly, creating shock or RF exposure hazards. By locking the energy source and tagging the equipment, you ensure it cannot be turned on until safe to do so and that the person performing the work is identified. This combination reduces the risk of injury and RF exposure while technicians service antennas, radios, or power supplies. The other ideas described don’t address stopping energy or protecting against RF exposure; they’re about calibration checklists, increasing RF exposure, or naming conventions, which don’t protect workers during servicing.
