Determine what OSHA fall-protection requirements apply to workers installing curtain wall or window glazing at height on a commercial job site.

Steps

1. Pull the current text of 29 CFR 1926 Subpart M ('Fall Protection') directly from osha.gov/laws-regs/regulations/standardnumber/1926/1926SubpartM
2. Confirm the general construction trigger in 1926.501: employees on a walking/working surface with an unprotected side or edge 6 feet or more above a lower level must be protected via guardrail systems, safety net systems, or personal fall arrest systems
3. Review 1926.502 for the detailed criteria each fall-protection system (guardrails, nets, PFAS) must meet before being deemed compliant
4. Search osha.gov's Standard Interpretations database for any glazing- or curtain-wall-specific letters of interpretation, since Subpart M is a general construction standard with no dedicated glazing subsection
5. Cross-reference the employer's site-specific fall protection plan against 1926 Subpart M Appendix E's non-mandatory sample plan format if work involves leading-edge or other conditions where conventional fall protection is infeasible
