Under 29 CFR 1926.501(b)(4), when must employees be protected from falling through skylights or other holes on a roof?
Employees must be protected from falling through skylights or other holes more than 6 feet above a lower level by a personal fall arrest system, covers, or guardrail systems.
- A cover used to protect a skylight must meet the cover strength criteria in 29 CFR 1926.502(i) (for example, support at least twice the weight of employees, equipment, and materials that may be imposed at any one time).
- If a skylight itself meets those cover criteria, OSHA will treat it as a compliant cover; otherwise you must provide a compliant cover, guardrail, or personal fall arrest.
See 29 CFR 1926 Subpart M and the OSHA letter of interpretation on skylight fall protection, Skylight fall protection criteria.
