The OSHA Hazard Communication Standard (29 CFR 1910.1200) requires every employer with hazardous chemicals in the workplace to maintain six things: a written program, an inventory of those chemicals, container labels, safety data sheets, employee training, and, for manufacturers and importers, hazard classification. It is the federal "right to know" rule, aligned to the Globally Harmonized System (GHS), and one of the most frequently cited standards in American industry.
This guide walks each of the six elements, quotes the controlling CFR text, and links the authoritative source on osha.gov and eCFR. Enforcement figures are drawn from the federal OSHA citation record.
HazCom is a top-cited standard in every manufacturing sector
In fabricated- and equipment-manufacturing (NAICS 33), failure to maintain a written hazard communication program, 1910.1200(e)(1), accounts for 15,428 federal OSHA citations, the second most-cited standard in the sector behind machine guarding. Training failures under 1910.1200(h)(1) add another 9,821 citations. In chemical manufacturing (NAICS 325), the written program is the single most-cited standard of all.
The six required elements
A written hazard communication program
1910.1200(e)(1)A document at each site describing how you handle labels, safety data sheets, and training. It must include a list of the hazardous chemicals present and the methods used to inform employees about non-routine tasks.
"Employers shall develop, implement, and maintain at each workplace, a written hazard communication program which at least describes how the criteria specified in paragraphs (f), (g), and (h) of this section for labels and other forms of warning, safety data sheets, and employee information and training will be met…"
29 CFR 1910.1200(e)(1) A list (inventory) of hazardous chemicals
1910.1200(e)(1)(i)A maintained inventory of every hazardous chemical in the workplace, identified by the same product identifier used on its SDS, so each entry traces to a sheet.
"A list of the hazardous chemicals known to be present using a product identifier that is referenced on the appropriate safety data sheet (the list may be compiled for the workplace as a whole or for individual work areas)…"
29 CFR 1910.1200(e)(1)(i) Labels and other forms of warning
1910.1200(f)Shipped containers carry full GHS labels (product identifier, signal word, hazard and precautionary statements, pictograms, supplier contact). Workplace containers must at minimum show the product identifier and words/pictures/symbols conveying the hazards.
"The chemical manufacturer, importer, or distributor shall ensure that each container of hazardous chemicals leaving the workplace is labeled, tagged or marked… [with] product identifier; signal word; hazard statement(s); pictogram(s); precautionary statement(s); and… name, address, and telephone number of the… responsible party."
29 CFR 1910.1200(f) Safety data sheets (SDS)
1910.1200(g)A 16-section SDS for every hazardous chemical, kept readily accessible to employees on every shift in their work area, reachable without first asking a manager to unlock a file.
"Employers shall have a safety data sheet in the workplace for each hazardous chemical which they use… [and] shall ensure that the safety data sheets are readily accessible during each work shift to employees when they are in their work area(s)."
29 CFR 1910.1200(g) Employee information and training
1910.1200(h)(1)Training at initial assignment and whenever a new hazard is introduced, covering how to read labels and SDS, the physical and health hazards present, and the details of your written program.
"Employers shall provide employees with effective information and training on hazardous chemicals in their work area at the time of their initial assignment, and whenever a new chemical hazard the employees have not previously been trained about is introduced into their work area."
29 CFR 1910.1200(h)(1) Hazard classification
1910.1200(d)(1)Manufacturers and importers classify each chemical by hazard class and category against Appendices A, B, and C. Employers who use chemicals rely on this classification but must still maintain the program above for what they receive.
"Chemical manufacturers and importers shall evaluate chemicals produced in their workplaces or imported by them to classify the chemicals in accordance with this section. For each chemical, the chemical manufacturer or importer shall determine the hazard classes, and where appropriate, the category of each class that apply to the chemical being classified."
29 CFR 1910.1200(d)(1)
HazCom in the enforcement record
The two HazCom paragraphs most often cited are the written program, 1910.1200(e)(1), and employee training, 1910.1200(h)(1). Both appear near the top of the citation record in every manufacturing sector. Counts below are federal OSHA citations from the enforcement record.
| Sector | (e)(1) written | (h)(1) training | Rank in sector |
|---|---|---|---|
| Fabricated / equipment mfg (NAICS 33) | 15,428 | 9,821 | #2 and #3 most-cited |
| Chemical / plastics / petroleum (NAICS 32) | 9,324 | 6,128 | #2 and #3 most-cited |
| Food / textile / apparel mfg (NAICS 31) | 2,687 | 1,804 | #2 and #4 most-cited |
| Food manufacturing (NAICS 311) | 1,626 | 1,164 | #2 and #7 most-cited |

What a HazCom gap costs in 2026
OSHA penalties are adjusted annually for inflation. As of January 2026, the maximum civil penalty is $16,550 per serious violation and $165,514 per willful or repeat violation. Because a single audit can find separate failures across the written program, labels, SDS access, and training, HazCom findings often issue as multiple grouped citations. Verify current figures against osha.gov/penalties before relying on them.
A quick self-audit
- Is there a written HazCom program at each site, naming the person responsible? 1910.1200(e)(1)
- Is the chemical inventory current, with each entry tied to an SDS product identifier? 1910.1200(e)(1)(i)
- Are all workplace containers labeled with the identifier and a hazard warning? 1910.1200(f)(6)
- Is an SDS readily accessible on every shift for every hazardous chemical? 1910.1200(g)(8)
- Were employees trained at initial assignment and when new hazards were introduced? 1910.1200(h)(1)
