OSHA Hazard Communication Standard (1910.1200): the HazCom compliance guide
What does OSHA's Hazard Communication Standard require?
The OSHA Hazard Communication Standard (29 CFR 1910.1200) requires every employer with hazardous chemicals in the workplace to maintain six elements, which are 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.
The guide covers each of the six elements, quotes the controlling CFR text, and links the official source on osha.gov and eCFR. Enforcement figures are drawn from the OSHA enforcement record, federal and state plan.
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 15,642 OSHA citations, the second most-cited standard in the sector behind machine guarding. Training failures under 1910.1200(h)(1) add another 9,981 citations. In chemical manufacturing (NAICS 325), the written program is the second most-cited standard, a few citations behind machine guarding.
The six required elements
A written hazard communication program
1910.1200(e)(1)The employer keeps a document at each site that describes how it handles labels, safety data sheets, and training, and the document 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)The employer maintains an inventory of every hazardous chemical in the workplace, identified by the same product identifier used on its SDS, so each entry can be matched 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 with the product identifier, signal word, hazard and precautionary statements, pictograms, and supplier contact. Workplace containers must at minimum show the product identifier and words, pictures, or symbols that convey 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)Every hazardous chemical needs a 16-section SDS, and the sheet must be kept readily accessible to employees on every shift in their work area, without a need to ask 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)Employees are trained at initial assignment and whenever a new hazard is introduced, and the training covers how to read labels and SDS, the physical and health hazards present, and the details of the 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 the manufacturer's 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, and the counts below are OSHA citations from the enforcement record, federal and state plan.
| Sector | (e)(1) written | (h)(1) training | Rank in sector |
|---|---|---|---|
| Fabricated and equipment manufacturing (NAICS 33) | 15,642 | 9,981 | #2 and #5 most-cited |
| Chemical, plastics, and petroleum (NAICS 32) | 9,429 | 6,210 | #2 and #4 most-cited |
| Food, textile, and apparel manufacturing (NAICS 31) | 2,728 | 1,839 | #3 and #6 most-cited |
| Food manufacturing (NAICS 311) | 1,649 | 1,189 | #3 and #9 most-cited |

What a HazCom gap costs in 2026
OSHA adjusts penalties each year for inflation. The amounts set in January 2025 are still in effect for 2026, and 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 result in multiple grouped citations. Verify current figures against osha.gov/penalties before relying on them.

Frequently asked questions
What is the OSHA Hazard Communication Standard (HazCom)?
The Hazard Communication Standard, 29 CFR 1910.1200, requires employers to inform and train workers about the hazardous chemicals they may be exposed to. A compliant program has six parts, which are a written program, a chemical inventory, labels that follow the Globally Harmonized System (GHS), safety data sheets (SDS), employee training, and, for manufacturers and importers, hazard classification. OSHA calls it the "right to know" standard.
What are the six required elements of a HazCom program?
First, each workplace needs a written hazard communication program per 1910.1200(e)(1). Second, employers need a list of hazardous chemicals per 1910.1200(e)(1)(i), and third, they need labels and other forms of warning per 1910.1200(f). Fourth, employers need safety data sheets per 1910.1200(g), and fifth, they need employee information and training per 1910.1200(h). Sixth, chemical manufacturers and importers must classify hazards per 1910.1200(d).
Who has to comply with 1910.1200?
Under 1910.1200(b)(1), the standard applies to any chemical "which is known to be present in the workplace in such a manner that employees may be exposed under normal conditions of use or in a foreseeable emergency." The standard covers nearly every employer that uses chemicals, including employers that are not chemical manufacturers. Manufacturers and importers carry the added duty to classify hazards and produce labels and SDS.
How often is HazCom training required?
Per 1910.1200(h)(1), training is required at the time of an employee's initial assignment and whenever a new chemical hazard the employees have not been trained on is introduced into their work area. The standard does not set a fixed annual interval, but employers commonly retrain periodically to keep "effective information and training" current.
Does HazCom require a safety data sheet for every chemical?
Yes. Under 1910.1200(g)(1), employers must have an SDS in the workplace for each hazardous chemical they use, and under 1910.1200(g)(8) the sheets must be readily accessible to employees during each work shift in their work area. SDS follow a standardized 16-section format set by 1910.1200(g)(2).
How much do HazCom violations cost?
Failure to develop and maintain a written program, 1910.1200(e)(1), is among the most-cited standards in U.S. manufacturing, with over 15,000 citations in fabricated and equipment manufacturing (NAICS 33) alone in the OSHA enforcement record. As of 2026, OSHA's maximum penalty is $16,550 per serious violation and $165,514 per willful or repeat violation, so an uncorrected program gap can compound across labels, SDS, and training.
