Hazard Communication is a study in enforcement contradiction. Across every industry, it holds OSHA's second rank in FY2025, behind only fall protection. But zoom into construction alone and it drops to ninth. Then a further surprise: a single state, Maryland, issued almost as many construction HazCom citations (609) as the entire federal system did nationwide (698). The two counts come from different enforcement universes: Maryland's citations are not part of the federal total. This analysis uses OSHA's FY2025 enforcement record to explain the paradox — where chemical-safety citations concentrate, why construction is different, and what the Maryland outlier reveals about how enforcement actually works.
Three FY2025 facts: HazCom is #2 most-cited across all industries (a rank, not a count — OSHA publishes no counts with this list) · but only #9 in construction (698 federal citations, ~$984K) · and Maryland alone cited it 609 times in construction, a count kept outside the federal total.
Hazard Communication, 29 CFR 1910.1200, was OSHA's second most-cited standard across all industries in fiscal 2025 but ninth in construction, where it is cited as 1926.59, and Maryland's State Plan alone issued 609 construction HazCom citations against 698 for the entire federal system.
The paradox: high everywhere, low in construction
If you only read OSHA's famous cross-industry "Top 10," you would conclude HazCom is a dominant construction problem. It ranks #2 overall, year after year. But that ranking is an all-industry aggregate — it sweeps in manufacturing, warehousing, chemical plants, auto shops, healthcare, and labs, where chemicals are the core hazard and HazCom citations pile up.
Construction is different. Its citation profile is dominated by working at height — fall protection, ladders, scaffolds, and fall training take the top four slots and the overwhelming majority of the penalty dollars. HazCom lands ninth on the construction list, with 698 federal citations under 1910.1200 and $984,054 in penalties (current amounts) in FY2025 — plus 14 more citations written under 1926.59, the construction transposition of the same standard. Construction crews absolutely handle hazardous chemicals — adhesives, solvents, fuels, silica, coatings — but the citations that define construction enforcement are about edges and elevations, not labels.
HazCom's two ranks — FY2025

The lesson for a contractor is subtle but important: HazCom being "only" ninth in construction is not permission to ignore it. It is ninth because falls are first — not because HazCom citations are rare or cheap. Unlabeled containers and missing programs are still among the easiest citations an inspector writes, and in the right state they are written a lot.
The Maryland outlier
Which brings us to the single most striking number in the construction HazCom dataset. When you break FY2025 construction HazCom citations out by State-Plan state, one jurisdiction towers over every other.
Construction HazCom citations by State-Plan state — FY2025
29 CFR 1910.1200, construction (NAICS 23). The entire federal national total (698) is shown as the scale reference — Maryland alone nearly reaches it.
Source: OSHA Frequently Cited Standards, FY2025 (per state, NAICS 23). Bars share one scale, set by the national federal total (698); state-plan counts such as Maryland's are not part of that total. Full State-Plan states that cite under the federal CFR numbering are shown; states using their own section numbers are omitted.
Maryland's MOSH issued 609 construction HazCom citations on its own, against 698 across all of federal OSHA's jurisdiction. Tennessee, the next-highest, managed 106. This is not a function of Maryland being a large construction market; it is an enforcement-posture signal. MOSH is among the most active State Plans in construction (4,132 citations in FY2025, second only to Washington) and it evidently writes HazCom deficiencies — unlabeled containers, missing written programs, absent SDSs — that many other jurisdictions pass over. If you build in Maryland, HazCom is not a back-burner standard; it is a front-line one.
Why HazCom is so citable in the first place
The reason HazCom generates high counts everywhere it is enforced comes down to how visible its violations are. Unlike an exposure limit that requires air sampling and a lab, a HazCom violation can be documented on a walkthrough:
The four pillars — and why each is easy to cite
Each pillar is independently citable, and none requires sampling or lab analysis — which is why a single inspection can produce several HazCom citations at once.
That visibility is also the good news: HazCom is one of the cheapest standards to actually comply with. A current written program, labeled secondary containers, accessible SDSs, and documented training close all four doors — and they cost a fraction of what a single citation does. See the complete OSHA HazCom compliance guide for the full build, and secondary container labels: OSHA rules for the most-cited pillar.
What the data says to do
- Rank your risk by your jurisdiction, not the national headline. HazCom is ninth in construction nationally — but first-tier in Maryland. Know which regime you're under. Compare states in OSHA penalties by state.
- Fix the visible pillars first. Labels and the written program are what an inspector sees in the first five minutes. A gap audit finds them before OSHA does.
- Don't confuse "low rank" with "low risk." Ninth place still meant 698 federal citations and $984,054 in FY2025 — plus everything the state plans added on top.
- The dollars are small; the injuries aren't. HazCom penalties are modest next to fall protection, but the chemical exposures they prevent — sensitization, burns, respiratory damage — are not. Enforcement rank is not the same as hazard severity.
What a HazCom citation actually cites
Construction HazCom is cited under 29 CFR 1926.59, which applies 29 CFR 1910.1200 word for word. The paragraphs behind most citations:
| Requirement | Paragraph |
|---|---|
| A written hazard communication program for the workplace | 29 CFR 1910.1200(e)(1) |
| On multi-employer sites, how SDSs, labels, and precautions are shared with other employers | 29 CFR 1910.1200(e)(2) |
| Labels on shipped containers from the manufacturer, importer, or distributor | 29 CFR 1910.1200(f)(1) |
| Workplace labels on containers filled or kept on site | 29 CFR 1910.1200(f)(6) |
| A safety data sheet for each hazardous chemical used | 29 CFR 1910.1200(g)(1) |
| SDSs readily accessible to workers during each work shift | 29 CFR 1910.1200(g)(8) |
| Training at initial assignment and when a new chemical hazard is introduced | 29 CFR 1910.1200(h)(1) |
| What the training must cover | 29 CFR 1910.1200(h)(3) |
Check your own state's HazCom record, not the national rank
Hazard Communication is second across all industries and ninth in construction because those two rankings measure different worlds — an all-sector aggregate versus a height-dominated trade. But the Maryland outlier is the reminder that rank is not destiny: a single state's enforcement posture can make a "ninth-place" standard the one that gets you cited. HazCom is cheap to comply with and easy to be cited for, which is the whole argument for closing its four visible doors before an inspector tests them.
HazCom is the standard OSHA cites most — close the gaps
HazCom drives more citations than almost any rule. HazComFast keeps your SDS library, labels, program, and training audit-ready so the #2 most-cited standard isn't your exposure.

Frequently Asked Questions
Where does Hazard Communication rank among OSHA's most-cited standards?
Across all industries, Hazard Communication (29 CFR 1910.1200) holds OSHA's #2 national rank in FY2025, second only to fall protection — a ranking OSHA publishes without citation counts. But within construction specifically it ranks only 9th, with 698 federal citations, because construction citations concentrate heavily on height-related hazards (falls, ladders, scaffolds). HazCom's high overall rank is driven by manufacturing, warehousing, healthcare, and other chemical-intensive sectors.
Which state cites construction HazCom the most?
Maryland. In FY2025, Maryland's state plan (MOSH) issued 609 construction Hazard Communication citations on its own, against 698 across all of federal OSHA's jurisdiction. The two counts come from different enforcement universes: Maryland's are not a share of the federal total. No other State-Plan state comes close: Tennessee was second at 106. Maryland's MOSH is a genuine HazCom-enforcement outlier, cited far above what construction employment alone would predict. In construction the citation reads 29 CFR 1926.59, which applies the requirements of 1910.1200.
Why is HazCom cited so often even though it isn't the deadliest hazard?
Because HazCom violations are visible and objectively citable. An unlabeled secondary container, a missing written program, an absent SDS, or an untrained worker are all easy for an inspector to document — no sampling or lab work required. HazCom is 'low-hanging fruit' in enforcement terms, which is why it ranks high on citation counts even though chemical exposures are not the leading cause of immediate construction death. The written program (29 CFR 1910.1200(e)(1)), workplace labels ((f)(6)), SDS access ((g)(8)), and training ((h)(1)) can all be checked on paper or with one question to a worker.
What are the most common HazCom citations?
The four pillars of the standard each generate citations: no written Hazard Communication program (1910.1200(e)), missing or inaccessible Safety Data Sheets (1910.1200(g)), unlabeled workplace/secondary containers (1910.1200(f)(6)), and inadequate employee training (1910.1200(h)). Unlabeled secondary containers and missing programs are among the most frequently documented because they are visible on a walkthrough.
Does this data include State-Plan states?
Yes, but separately. The federal figure (698 construction HazCom citations, $984,054 in penalties) covers federal-jurisdiction states. The 22 full State-Plan states cite under their own programs — Maryland 609, Tennessee 106, Virginia 41, and so on — and those are additional. The data comes from OSHA's Frequently Cited Standards tool, construction (NAICS 23), FY2025. State Plans must be at least as effective as federal OSHA (29 U.S.C. 667(c)(2)), but they enforce on their own.
