In FY2025, Iowa OSHA (IOSH) cited 29 CFR 1910.147 (Lockout/Tagout (LOTO)) 1 times on Iowa construction jobsites with $2,232 in penalties for it (current amounts), about 0.3% of every construction citation the state issued that year. That put it 49th on Iowa's most-cited construction list for FY2025.
What Iowa's own rule says
Iowa adopts the federal lockout/tagout standard without amendment, so its construction exclusion travels with it. Note where the chapter now lives: general industry safety and health rules moved from 875—Chapter 10 to 481—Chapter 210 on July 9, 2025. The move was editorial rather than substantive, but energy control procedures that cite 875 IAC 10 by number are pointing at a chapter that has been transferred.
29 CFR 1910.147 as adopted by 481—210.4(88)The duty matches the federal text. Only the citation number differs.

How Iowa Enforces 29 CFR 1910.147
Iowa runs an OSHA-approved State Plan administered by Iowa OSHA (IOSH), which covers private-sector construction. Its compliance officers enforce Iowa'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 481—210.4(88). Iowa OSHA (IOSH) cited 29 CFR 1910.147 1 time in Iowa construction in FY2025 (OSHA Frequently Cited Standards). Iowa 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 Iowa 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 Iowa
Which Iowa industries most often face a Lockout/Tagout (LOTO) inspection?
Lockout/Tagout (LOTO) inspections reach general-industry employers in Iowa, not the construction trades. Iowa OSHA (IOSH) 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 Iowa?
29 CFR 1910.147 is enforced against general-industry employers in Iowa, so the construction citation totals published for Iowa (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 Iowa OSHA require a written lockout/tagout program?
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 Iowa, Iowa OSHA, the state's own 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 Iowa?
Iowa OSHA, part of the Iowa Division of Labor within Iowa Workforce Development. Iowa 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 Iowa without an inspection?
Yes. OSHA's On-Site Consultation Program in Iowa is IOSHA Consultation Program (Department of Inspections, Appeals, & Licensing). 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.
