What Arizona's own rule says
Lockout/tagout applies in Arizona as adopted federal text with the July 14, 2020 cut-off, and it carries the federal construction exclusion. The state's boundary rule matters here: because R20-5-602 does not apply to conditions and practices that are the subject of R20-5-601, hazardous energy control on a construction site runs through the adopted Part 1926 provisions, not through 1910.147. It is the same split as under federal jurisdiction, stated in the state rule rather than left to the federal scope paragraph.
29 CFR 1910.147 as adopted by A.A.C. R20-5-602The duty matches the federal text. Only the citation number differs.

How Arizona Enforces 29 CFR 1910.147
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 1910.147 as adopted by A.A.C. R20-5-602. Arizona Division of Occupational Safety and Health (ADOSH) issued no citations under 29 CFR 1910.147 in Arizona construction in FY2025. Arizona applies the federal penalty maximums.
29 CFR 1910.147 is a general-industry standard and does not govern construction work. “This standard does not cover the following: (A) Construction and agriculture employment”. Branding a construction program “1910.147 compliant” cites the wrong standard. Unlike confined spaces, Part 1926 has no wholesale re-enactment of 1910.147: construction energy-control duties are spread across hazard-specific provisions, so no single construction equivalent is named here. An Arizona contractor auditing against 29 CFR 1910.147 is auditing against the wrong standard. The citation an officer writes on a construction site will name the 1926 provision, not this one.

Lockout/Tagout (LOTO) FAQ for Arizona
Which Arizona industries most often face a Lockout/Tagout (LOTO) inspection?
Lockout/Tagout (LOTO) inspections reach general-industry employers in Arizona, not the construction trades. Arizona Division of Occupational Safety and Health (ADOSH) inspects these employers directly and may apply requirements beyond the federal standard. A construction employer is not governed by 29 CFR 1910.147, and the construction-side duties on this subject are not concentrated in a single standard. Check your Part 1926 obligations instead.
How often is Lockout/Tagout (LOTO) cited in Arizona?
29 CFR 1910.147 is enforced against general-industry employers in Arizona, so the construction citation totals published for Arizona (OSHA Frequently Cited Standards, NAICS 23) do not measure it. “This standard does not cover the following: (A) Construction and agriculture employment”. Branding a construction program “1910.147 compliant” cites the wrong standard. Unlike confined spaces, Part 1926 has no wholesale re-enactment of 1910.147: construction energy-control duties are spread across hazard-specific provisions, so no single construction equivalent is named here. A construction employer is not governed by 29 CFR 1910.147, and the construction-side duties on this subject are not concentrated in a single standard. Check your Part 1926 obligations instead.
Does ADOSH require a written lockout/tagout program in Arizona?
Yes. 29 CFR 1910.147 requires an energy control program with documented procedures for the equipment serviced, employee training, and a periodic inspection of each procedure at least annually. In Arizona, ADOSH, the state's own OSHA program, can cite the missing program, missing machine-specific steps, or the failure to isolate stored energy before service.
Who enforces lockout/tagout (1910.147) in Arizona?
ADOSH, the Arizona Division of Occupational Safety and Health. Arizona runs a full OSHA-approved State Plan, so a state compliance officer inspects and cites 1910.147 on private jobsites.
Can I get free OSHA help in Arizona without an inspection?
Yes. OSHA's On-Site Consultation Program in Arizona is Consultation & Training, Industrial Commission of Arizona (Division of Occupational Safety & Health). OSHA describes it this way: "Primarily for smaller businesses, no-cost, confidential consultations help employers identify and address hazards and establish or improve safety and health programs." Consultations are separate from OSHA enforcement, and the employer commits to correcting serious hazards.
