What minimum fall protection requirement is commonly needed for work at height on construction sites?

• A. 3 feet or more requires fall protection
• B. 6 feet or more requires fall protection (guardrails, nets, or harness)
• C. 10 feet or more requires fall protection
• D. Fall protection is not required for work at height

Answer: (B)

Height-based fall protection is required on construction sites to prevent injuries from falls. When workers are at a height where a fall could reach a lower level, protective measures must be in place. The commonly applied threshold is six feet or more. At or above that height, you need guardrails, safety nets, or a personal fall arrest system such as a harness and lanyard anchored securely. This standard balances practicality with safety, recognizing that injuries become more likely and severe as height increases. Options that set the threshold at three feet or ten feet, or claim protection isn't required, don't align with typical construction safety rules.
