In FY2025, Iowa OSHA (IOSH) cited 29 CFR 1910.1200 (HazCom / GHS) 2 times on Iowa construction jobsites with $1,128 in penalties for it (current amounts), about 0.7% of every construction citation the state issued that year. That put it 33rd on Iowa's most-cited construction list for FY2025.
What Iowa's own rule says
“Only mandatory provisions (i.e., provisions containing the word "shall" or other mandatory language) of standards incorporated by reference are adopted under the Act.”
Iowa adopts 29 CFR Part 1910 from 1910.20 onward through a list of named Federal Register notices: 277 of them, the most recent dated October 9, 2024, which is the hazard communication correction that followed the 2024 GHS rule. Two Iowa-specific provisions shape how that adoption reads. Rule 481—210.2(88) limits incorporation to the mandatory provisions of a referenced standard, so advisory language inside an incorporated consensus standard is not itself enforceable here. And Iowa's own Hazardous Chemical Risks Right to Know chapter, 875—Chapter 110, was rescinded effective May 11, 2022. The state right-to-know layer some Iowa employers built programs around is gone, leaving the adopted federal standard.
481—210.4(88), with 481—210.2(88) on incorporated standardsThe duty itself differs from the federal text.

How Iowa Enforces 29 CFR 1910.1200
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 481—210.4(88), with 481—210.2(88) on incorporated standards, which differs from the federal text (see the state rule above). Iowa OSHA (IOSH) cited 29 CFR 1910.1200 2 times in Iowa construction in FY2025 (OSHA Frequently Cited Standards). Iowa applies the federal penalty maximums.
In Iowa, the FY2025 citations under 29 CFR 1910.1200 went most often to Industrial Building Construction (1) and Plumbing, Heating, and Air-Conditioning Contractors (1). A single inspection can produce several per-instance citations. Recurring self-audits against 481—210.4(88), with 481—210.2(88) on incorporated standards, before an officer arrives, are the most reliable defense.
