Safety belt must be provided if worker is this high?

• A. 15'
• B. 6'
• C. 10'
• D. 3'

Answer: (A)

Fall protection is required whenever there is a real risk of falling from an elevated position, so a safety belt or other fall‑arrest device is provided to protect the worker. In this particular question, the scenario uses a threshold of 15 feet, meaning the safety belt must be provided when a worker is 15 feet or higher above the lower level. That’s why 15 feet is the best answer here—it matches the stated requirement for this item. The lower heights listed would not meet the trigger in this question’s context, even though many codes in other contexts set a lower threshold (such as 6 feet) for fall protection.
