Rank states by total OSHA citations and you learn which have big construction markets. Rank standards nationally and you learn that falls dominate. But cross the two — break FY2025 citations down by state AND by standard at once — and a pattern appears that neither ranking shows: every state agency has an enforcement signature. Maryland pounds labels and ladders. Virginia concentrates on scaffolds. Tennessee leans into chemical standards. This analysis builds an original heatmap from OSHA's own per-state, per-standard data and reads the fingerprints — because the standard your state cites second is the one most likely to surprise you.
The read: Fall protection is #1 almost everywhere. The differences are in the second tier — and they are large. Maryland's 609 HazCom citations and Virginia's $1.27M in scaffold penalties are signatures, not noise.
Fall protection under 29 CFR 1926.501 leads OSHA construction citations almost everywhere, but each state agency has its own second tier: Maryland's MOSH wrote 609 construction HazCom citations in fiscal 2025, against 698 for the whole federal system.
The heatmap
Here are six of the highest-volume full State-Plan agencies against six leading construction standards. Darker cells mean more citations. Read across a row to see a state's signature; read down a column to see which states enforce a given standard hardest.
FY2025 construction citations by state × standard

The column for Fall protection is dark all the way down — falls lead in every one of these states, exactly as the national data predicts. The interest is everywhere else. Two cells jump off the grid: Maryland's 609 HazCom citations (darker than its own fall count) and its 390 ladder citations. No other state is close on either. That is a signature you could pick out blind.
Reading the signatures
Each row tells a small story about how that agency enforces.
What each state's row reveals
These are relative emphases within each state, drawn from raw FY2025 counts. Fall protection leads every row; the signature is what comes next.
The analytical payoff is that "OSHA enforcement" is not one thing you can prepare for generically. A contractor optimizing only for fall protection is well-defended in North Carolina and under-defended in Maryland, where an inspection is as likely to cite an unlabeled bucket or a damaged ladder as an unprotected edge. The signature tells you where your second line of defense needs to be.
Why the signatures exist
Three forces shape a state's enforcement fingerprint, and separating them matters for reading the map honestly:
- Agency priorities. A state plan sets its own emphasis programs and inspector guidance. Maryland's HazCom volume reflects a deliberate focus on labeling and written programs that most agencies don't share.
- Local industry mix. A state heavy in chemical processing or refining will surface more HazCom and respiratory citations even on construction sites adjacent to that work; a state dominated by residential framing will skew toward falls and ladders.
- Raw size. Bigger construction markets generate bigger numbers. That is why this heatmap is read across rows (relative emphasis) rather than by comparing absolute cells between states of different sizes. Maryland's 609 is a signature because it dwarfs Maryland's own other counts, not merely because it is a large number.
One clean way to strip size out entirely is to read each state's secondary standard relative to its own fall-protection count — a within-state ratio a big or small market can't distort. On that measure Maryland is extraordinary: its HazCom-to-fall ratio is 609 ÷ 434 ≈ 1.4, the only state here that cites Hazard Communication more than it cites falls. Tennessee's is 106 ÷ 115 ≈ 0.9 (chemicals nearly level with falls) and Virginia's scaffold-to-fall ratio is 192 ÷ 223 ≈ 0.86. Compare North Carolina's HazCom-to-fall ratio of 27 ÷ 378 ≈ 0.07, and the signatures stop looking like an artifact of state size and become what they claim to be — real differences in what each agency emphasizes once falls are held constant.
What each column actually cites
The heatmap columns are standards, and each has a short core requirement an auditor can check on site:
| Column | Core requirement | Rule |
|---|---|---|
| Fall protection | Protection at 6 feet on construction work | 29 CFR 1926.501(b)(1) |
| Scaffolds | Fall protection at 10 feet on scaffolds | 29 CFR 1926.451(g)(1) |
| Ladders | Side rails 3 feet above the landing | 29 CFR 1926.1053(b)(1) |
| Hazard Communication | A written program, applied to construction by 1926.59 | 29 CFR 1910.1200(e)(1) |
| Respiratory protection | A written, worksite-specific program, adopted by 1926.103 | 29 CFR 1910.134(c)(1) |
| Lockout/tagout (general industry) | An energy control program | 29 CFR 1910.147(c)(1) |
What a contractor should do with the map
- Learn your state's second column. Everyone must control falls. Find out what your state agency cites next — ladders and labels in Maryland, scaffolds in Virginia — and harden that specifically.
- Don't import assumptions across state lines. A program tuned to one state's signature can be blind to another's. A multi-state contractor needs a program that covers every dark cell, not just its home state's.
- Maryland is the HazCom warning. If your footprint includes Maryland, treat Hazard Communication as a first-tier standard: current written program, labeled secondary containers, accessible SDSs, documented training. See the complete OSHA HazCom compliance guide and the deeper HazCom enforcement analysis.
- Ladders are underrated everywhere. Ladders (1926.1053) are the #2 construction standard nationally and a dark cell in most rows — cheap to get right, easy to be cited for.
Control falls first, then your state's own signature
A national ranking tells you falls are the problem, and they are — everywhere. But construction companies don't operate in "the nation"; they operate in states, and each state's enforcement has a fingerprint that a national number erases. The heatmap makes the fingerprints visible: Maryland's documentation focus, Virginia's scaffolds, Tennessee's chemicals, North Carolina's pure-height profile. Control falls first, because you must. Then read your state's signature and build the second line of defense where the data says the citations will actually come from.

Frequently Asked Questions
Do different state OSHA programs cite different standards?
Yes, distinctly. When you break FY2025 construction citations down by state and by standard, each state agency shows a recognizable 'signature.' Maryland (MOSH) cites Hazard Communication (609) and ladders (390) at volumes far above other states; Virginia (VOSH) concentrates on scaffolds (192 citations, over $1.27 million); Tennessee (TOSHA) spreads across chemical standards with unusually high HazCom (106) and respiratory (66) counts. Fall protection leads almost everywhere, but the secondary emphasis varies a lot. Each State Plan must be at least as effective as federal OSHA (29 U.S.C. 667(c)(2)), which leaves room for different priorities.
Which state cites Hazard Communication in construction the most?
Maryland, by a wide margin: 609 construction HazCom citations in FY2025, roughly six times the next-highest state plan (Tennessee, 106). Federal OSHA issued 698 across its own jurisdiction, and Maryland's state-plan citations are not part of that total. Maryland's MOSH is a genuine outlier on labeling and written-program enforcement. In construction those citations read 29 CFR 1926.59, which applies 1910.1200.
What is an 'enforcement signature'?
It's the distinctive pattern of which standards a state agency cites most, relative to others. Because fall protection dominates construction everywhere, the signature is really about the SECONDARY emphasis — whether an agency also leans hard on ladders, scaffolds, chemical standards, or lockout/tagout. That pattern reflects each agency's enforcement priorities, local industry mix, and inspector focus, and it is invisible in a single national ranking. The standards behind the columns are the same everywhere, from fall protection (29 CFR 1926.501) to respiratory protection (1910.134, adopted by 1926.103).
Why does fall protection top the list in almost every state?
Because falls are the leading cause of construction death nationwide and fall hazards are the most visible and objectively citable — an inspector can see an unprotected edge from the ground. Fall protection (1926.501) is the #1 construction standard federally and in nearly every full State-Plan state that cites under the federal numbering. The variation between states is in what comes AFTER fall protection.
How was this heatmap built?
From OSHA's Frequently Cited Standards tool, which reports each full State-Plan state's own FY2025 construction citations (NAICS 23) by CFR standard. The heatmap shows raw citation counts for six leading standards across six of the highest-volume State-Plan states. Counts are not normalized for construction employment, so a larger state will tend toward larger numbers; the 'signature' is the relative emphasis across standards within each state.
