Under OSHA construction standards, at what height above a lower level does fall protection generally become required for workers on a construction site?
- A2 feet
- B4 feet
- C6 feetCorrect
- D20 feet
Why: OSHA's construction fall-protection rule (29 CFR 1926.501) generally requires protection — such as guardrails, safety nets, or personal fall-arrest systems — when a worker is exposed to a fall of 6 feet or more to a lower level. (Note the general-industry trigger is 4 feet, but on construction sites the 6-foot rule applies.) Falls are consistently a leading cause of construction fatalities, which is why this threshold is heavily tested and enforced.
