The citation that proves the fall hazard wasn't an accident.

The program must enable each employee to recognize fall hazards and know the procedures that minimize them — which the standard itemizes: the nature of hazards in the work area; procedures for erecting, maintaining, disassembling, and inspecting the protection systems used; the use and operation of guardrails, personal fall arrest, safety nets, warning lines, and safety monitoring as applicable; each employee's role in monitoring systems and fall protection plans; material handling and storage on roofs; and the requirements of Subpart M itself.

The trainer matters as much as the syllabus: training must be provided by a competent person qualified in these areas. A tailgate video with a sign-in sheet doesn't satisfy the standard when the trainer can't answer the crew's questions about the anchorage on this roof.

§1926.503(b) requires a written certification with the employee's name, the training date (or most recent retraining), and the trainer's or employer's signature. In an inspection, this record is the first document requested after a fall hazard is observed — and its absence converts "we trained them verbally" into an unprovable claim. Retraining obligations trigger when the employer has reason to believe the training didn't stick: near-misses, observed misuse, changed conditions, or new equipment.

The enforcement logic explains the rankings: an inspector who documents an unprotected edge under §1926.501 asks who trained the exposed employees. The FY2025 data — §1926.501 at #1 and §1926.503 at #7 — is that conversation, repeated thousands of times.

RegLogic keeps §1926.503 one search away, with the certification-record requirements and the LOIs on trainer qualifications attached in context. Safety trainers use notes to map each course module to the paragraph it satisfies — so when an inspector asks how the program covers §1926.503(a)(2)(iv), the answer is pinned to the standard itself.
