The HazIndex Machine Guarding OSHA Violations - Top Industries by OSHA Citations ranking shows published recorded citations for Machine Guarding during the active public release. HazIndex is an independent publisher of workplace-safety rankings and analysis derived from public OSHA enforcement data, and this article summarizes the ranking without adding a new raw-data calculation.
The ranking covers OSHA citations issued from January 1, 2021 through December 31, 2025. It groups the public read-model results by industry group and sorts them by citations. The parent HazIndex Machine Guarding index provides the broader index context for OSHA standard 1910.212.
What this ranking measures
This ranking measures recorded citations already published in the HazIndex public read model. It does not normalize for employment, number of establishments, hours worked, inspection volume, or production levels. The ranking is therefore best read as a structured view of recorded OSHA enforcement outcomes, not as a complete measure of present-day safety conditions.
Key findings from the published rows
- Architectural and Structural Metals Manufacturing ranks first with 714 citations.
- Machine Shops; Turned Product; and Screw, Nut, and Bolt Manufacturing ranks second with 518 citations, leaving a first-to-second gap of 196.
- The top three published rows account for 20.1% of the published ranking total.
- The top five published rows account for 28.9%, and the top ten account for 40.2%.
- The ranking includes 100 published industry groups with a published ranking total of 8,663 citations.
Leading results
The leading rows show where recorded OSHA enforcement activity is highest within this published ranking. Architectural and Structural Metals Manufacturing is first, followed by Machine Shops; Turned Product; and Screw, Nut, and Bolt Manufacturing and Plastics Product Manufacturing. Those positions are rank statements from the HazIndex table; they do not establish why the entities appear in that order.
- Rank 1: Architectural and Structural Metals Manufacturing with 714 citations.
- Rank 2: Machine Shops; Turned Product; and Screw, Nut, and Bolt Manufacturing with 518 citations.
- Rank 3: Plastics Product Manufacturing with 508 citations.
- Rank 4: Other Fabricated Metal Product Manufacturing with 450 citations.
- Rank 5: Other Wood Product Manufacturing with 317 citations.
The difference between the first and second rows is 196 in the selected metric. Smaller rank gaps should be interpreted carefully because a nearby value can separate adjacent positions. Larger gaps can make the top position more visually distinct, but the ranking itself still does not establish a cause for the difference.
Concentration and distribution
The published total across this ranking is 8,663 citations. The first three rows account for 20.1% of that total, while the first five account for 28.9%. By the tenth row, the visible top tier accounts for 40.2% of the published total.
Those percentages describe the distribution inside this HazIndex ranking only. They are useful for seeing whether recorded enforcement outcomes are concentrated near the top of the table or spread more broadly across the ranked industry groups. They do not show whether unranked entities had no OSHA activity, and they do not replace the official records maintained by OSHA.
What the ranking does not show
The ranking does not prove that one industry group is less safe than another, and it does not measure injuries, near misses, or current operating practices. It also does not show every workplace-safety event. It is a public HazIndex analysis layer over recorded OSHA enforcement data for a defined period.
Methodology and sources
HazIndex builds public ranking pages from materialized ranking rows, ranking definitions, yearly period values, and release metadata in the active public release. This Insight uses the same published output shown on the canonical ranking page and does not query large OSHA source-row tables or change the ranking calculation.
Readers can continue with the canonical HazIndex ranking, the parent HazIndex index, the HazIndex workplace-safety indexes hub, and the HazIndex dataset license and usage page. For authoritative case-level details, consult official OSHA resources such as OSHA Data and OSHA Establishment Search.
