The elevation threshold for fall protection is ____.

• A. 4'(1.2 m)
• B. 6'(1.8 m)
• C. 8'(2.4 m)
• D. 10'(3.0 m)

Answer: (B)

Fall protection is required at the height where a fall could cause serious injury. In construction contexts, the standard threshold is six feet (about 1.8 meters) above a lower level. At or above this height, protective measures such as guardrails, safety nets, or personal fall arrest systems must be in place to prevent or mitigate a fall. This six‑foot rule is the version commonly taught for electricians and other construction workers. Lower thresholds exist in general industry settings (four feet), but the scenario here reflects the construction rule, which is why six feet is the correct threshold.
