What Arizona's own rule says
Scaffolding is adopted federal text in Arizona at the February 24, 2021 cut-off, with the ten-foot fall protection trigger and the competent-person duties intact. Arizona did not amend Subpart L. The structural point to carry is the one the rule states itself: the incorporation does not include amendments or editions published after that date, so a federal change announced since then is not in force here until the Industrial Commission moves the date by rulemaking.
29 CFR 1926.451 as adopted by A.A.C. R20-5-601The duty matches the federal text. Only the citation number differs.
Falls and work deaths in Arizona, 2024
Arizona recorded 94 fatal work injuries in 2024, down from 103 in 2023. Falls, slips and trips caused 17 of them (18%). Construction accounted for 24, 9 of them from falls, slips and trips.

How Arizona Enforces 29 CFR 1926.451
Arizona runs an OSHA-approved State Plan administered by Arizona Division of Occupational Safety and Health (ADOSH), which covers private-sector construction. Its compliance officers enforce Arizona's own standards, which must be at least as effective as federal OSHA's and may go further. On this subject the rule is 29 CFR 1926.451 as adopted by A.A.C. R20-5-601. Arizona Division of Occupational Safety and Health (ADOSH) cited 29 CFR 1926.451 7 times in Arizona construction in FY2025 (OSHA Frequently Cited Standards). Arizona applies the federal penalty maximums.
In Arizona, the FY2025 citations under 29 CFR 1926.451 went most often to Commercial and Institutional Building Construction (4) and Siding Contractors (2). A single inspection can produce several per-instance citations. Recurring self-audits against 29 CFR 1926.451, before an officer arrives, are the most reliable defense.
