29 CFR 1910.1200

29 CFR 1910.1200, the Hazard Communication Standard (HazCom), is OSHA's chemical right-to-know rule: employers must classify the hazards of the chemicals they use and communicate them through a written program, GHS-aligned container labels, Safety Data Sheets, and worker training. It was second on OSHA's list of most-cited standards for FY2025.

29 CFR 1910.1200 at a glance

What it requires: Communicate chemical hazards via labels, safety data sheets (SDS), and training
Who it covers: Virtually every employer whose workers may be exposed to a hazardous chemical
The 3 pillars + program: A written program, a chemical list, GHS labels, 16-section SDS, and employee training
Enforcement rank: #2 most-cited OSHA standard

The #1 confusion: HazCom is a written PROGRAM, not just a binder of SDSs; OSHA requires 8 pictograms, not 9

What 29 CFR 1910.1200 requires (plain English)

29 CFR 1910.1200 (the Hazard Communication Standard (HazCom), often called the "Right to Know" standard) is the foundation of chemical safety in U.S. workplaces. It requires every employer whose employees may be exposed to hazardous chemicals to communicate those hazards through three pillars: GHS-formatted container labels, Safety Data Sheets (SDS), and employee training: all tied together by a written hazard communication program.

The standard is built on the Globally Harmonized System (GHS). Chemical manufacturers and importers must classify each chemical's hazards and produce a compliant label (product identifier, signal word, hazard and precautionary statements, pictograms, supplier information) and a 16-section SDS. Downstream employers must keep those SDSs readily accessible during every work shift, label every container in the workplace, maintain a list of the hazardous chemicals present, and train workers on the hazards and protective measures. OSHA requires eight of the nine GHS pictograms: the ninth, the environmental pictogram (GHS09), is outside OSHA's jurisdiction.

HazCom was second on OSHA's FY2025 list of most-cited standards because it applies so broadly: almost every workplace uses cleaning products, solvents, paints, fuels, or process chemicals. The 2024 update aligned HazCom with GHS Revision 7, adding new hazard classes and revised label elements; a January 2026 final rule extended the compliance deadlines. Employers must reach the substances-employer deadline for updated labels, program, and training, then the mixtures-employer deadline that follows.

The regulatory text

“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, and which also includes the following: (i) 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); and, (ii) The methods the employer will use to inform employees of the hazards of non-routine tasks (for example, the cleaning of reactor vessels), and the hazards associated with chemicals contained in unlabeled pipes in their work areas.”

29 CFR 1910.1200(e)(1)

29 CFR 1910.1200 paragraph by paragraph

The paragraph number on a citation points to one of these. Each entry gives the text, what the compliance officer checks, and what closes the item.

1910.1200(e)(1) Written hazard communication program

“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”

1910.1200(e)(1), verbatim

What the compliance officer checks: The written program is reviewed for every applicable element of (e), (f), (g) and (h), and each element is checked for implementation. The chemical list must use product identifiers that match the SDS and label and include every chemical present, stored ones too (CPL 02-02-079, X.E.4).

What closes it: A written program that says how labels, SDSs and training are handled, with the (e)(1)(i) chemical list and the (e)(1)(ii) methods for non-routine tasks and unlabeled pipes. Where labeling, SDSs, the inventory and training are all in place and only the writing is missing, the directive treats (e)(1) as de minimis and no citation issues (CPL 02-02-079, X.E.5).

1910.1200(e)(2) Multi-employer workplaces

“Employers who produce, use, or store hazardous chemicals at a workplace in such a way that the employees of other employer(s) may be exposed (for example, employees of a construction contractor working on-site) shall additionally ensure that the hazard communication programs developed and implemented under this paragraph (e) include the following”

1910.1200(e)(2), verbatim

What the compliance officer checks: A citation under (e)(2)(i), (ii) or (iii) normally issues when the program lacks the method for giving other employers SDS access, telling them about precautions, or telling them about the labeling system. A general contractor that uses no chemicals but whose employees are exposed to other employers' chemicals still needs a program and training, cited under (e)(1) and (h) (CPL 02-02-079, X.E.5).

What closes it: Write the three methods into the program. You don't have to hand other employers the SDSs: telling them where they are kept, such as the general contractor's trailer, is enough (CPL 02-02-079, X.E.2).

1910.1200(f)(6) Workplace labeling

“Except as provided in paragraphs (f)(7) and (f)(8) of this section, the employer shall ensure that each container of hazardous chemicals in the workplace is labeled, tagged or marked with either”

1910.1200(f)(6), verbatim

What the compliance officer checks: (f)(6)(ii) is cited when workplace containers are unlabeled or miss the product identifier or hazard description; (f)(6)(i) when an employer copies the shipped label but leaves information out or gets it wrong. A portable container labeled under the stationary-container rules is also (f)(6)(ii) (CPL 02-02-079, X.F.10).

What closes it: Label each workplace container with the shipped-label elements of (f)(1)(i) to (v), or with the product identifier plus words, pictures or symbols giving general hazard information. A portable container filled for the immediate use of the person who fills it is exempt under (f)(8).

1910.1200(g)(1) An SDS for each hazardous chemical used

“Employers shall have a safety data sheet in the workplace for each hazardous chemical which they use.”

1910.1200(g)(1), verbatim

What the compliance officer checks: (g)(1) is cited whenever an employer does not have an SDS, unless it can show a good-faith effort to get it from the manufacturer, importer or distributor, such as documented phone calls, emails or letters (CPL 02-02-079, X.G.7).

What closes it: An SDS for every hazardous chemical in use, and a written record of your requests for any a supplier hasn't sent.

1910.1200(g)(8) SDS access during every shift

“The employer shall maintain in the workplace copies of the required safety data sheets for each hazardous chemical, and shall ensure that they are readily accessible during each work shift to employees when they are in their work area(s). (Electronic access and other alternatives to maintaining paper copies of the safety data sheets are permitted as long as no barriers to immediate employee access in each workplace are created by such options.)”

1910.1200(g)(8), verbatim

What the compliance officer checks: (g)(8) is cited when the employer has the SDS but it isn't readily accessible to employees in their work area, and when electronic access has no adequate backup for emergencies. On a multi-employer site, an employer that brings chemicals in and doesn't tell the other employers about them or where the SDSs are is cited under (g)(8) grouped with (e)(2)(i) (CPL 02-02-079, X.G.7).

What closes it: SDSs reachable from the work area during the shift, on paper or electronically with no search for the worker to run, a backup for a device or network failure, and workers trained on both. On a construction site the SDSs can stay at the main office if a worker gets a requested one without delay, by phone, email or tablet (CPL 02-02-079, X.G).

Federal construction citations in fiscal year 2025: 108 of the 698 under 1910.1200 (HazComFast count from Labor Department enforcement data). SDS access on the jobsite

1910.1200(h)(1) Information and training

“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.”

1910.1200(h)(1), verbatim

What the compliance officer checks: (h)(1) is cited when no training was given or the training was inadequate, including training not given in a language and at a literacy level employees understand. Missing information elements are cited under (h)(2) and missing training content under (h)(3), each group of subsections cited together (CPL 02-02-079, X.H.3).

What closes it: Train at initial assignment and whenever a new chemical hazard enters the work area, in a language and at a literacy level the crew understands, covering the (h)(2) information and the (h)(3) training elements. (h)(2) and (h)(3) drew 40 more federal construction citations in fiscal year 2025.

Key facts about 29 CFR 1910.1200

HazCom requires a written program, a list of hazardous chemicals, GHS labels, 16-section SDSs, and employee training.
SDSs must be readily accessible to employees during each work shift (1910.1200(g)(8)).
OSHA requires 8 of the 9 GHS pictograms; the environmental pictogram (GHS09) is not required on U.S. workplace labels.
The SDS has a standardized 16-section format; sections 12–15 are included for GHS harmonization but not enforced by OSHA.
Training is required at initial assignment and whenever a new chemical hazard is introduced.
HazCom is OSHA's #2 most-cited standard, and applies to construction via 29 CFR 1926.59.
The 2024 update aligned HazCom with GHS Revision 7; a Jan 2026 rule extended the phased compliance deadlines.

Common HazCom / GHS violations

Deficiencies OSHA cites under 29 CFR 1910.1200 include the ones below, in no particular order. Distinct deficiencies can be cited as separate items, and each serious item carries up to $16,550 (2026). Broader per-instance stacking exists but is a discretionary, case-by-case OSHA enforcement policy, not an automatic multiplier.

No written hazard communication program (or one that does not reflect the workplace) (1910.1200(e)).
Safety data sheets missing, outdated, or not readily accessible during each shift (1910.1200(g)).
Secondary/workplace containers not labeled with the required information (1910.1200(f)(6)).
Employees not trained on chemical hazards or on the labeling and SDS systems (1910.1200(h)).
No list of the hazardous chemicals present in the workplace (1910.1200(e)(1)(i)).

HazCom is a program, not a binder, and OSHA requires 8 pictograms, not 9

Two misconceptions dominate. First, employers often equate 'HazCom compliance' with having a binder of Safety Data Sheets. The SDS collection is only one of three pillars; the standard requires a WRITTEN program, a chemical inventory, compliant labeling of every container, and documented training. A perfect SDS binder with no written program and no training is still a citable violation. Second, people cite 'nine GHS pictograms.' The GHS defines nine, but OSHA's HazCom requires only eight on U.S. workplace labels: the environmental pictogram (GHS09) covers aquatic hazards outside OSHA's jurisdiction and is voluntary. So a compliant U.S. label may lawfully omit GHS09.

What OSHA inspectors look for

A compliance officer asks for the written hazard communication program, the list of hazardous chemicals and the safety data sheet for a chemical in use, then checks that workers can get to the SDSs during their shift and can explain the labels and the hazards. In federal construction inspections in FY2025, the paragraphs cited most were (e)(1), with 262 citations; (h)(1), with 167; and (g)(8), with 108 (HazComFast count from Labor Department enforcement data).

Example: how a violation is cited

A shop keeps solvents and degreasers in unlabeled spray bottles, has no written program and cannot produce the SDS for a chemical in use. Those failures fall under three paragraphs, 1910.1200(e)(1), (f)(6) and (g)(8), and OSHA can cite each as its own item.

Illustrative example, not a specific OSHA case.

HazCom / GHS compliance checklist

Use this to evaluate your compliance with 29 CFR 1910.1200. Each item is a key requirement OSHA may verify during an inspection.

Develop a written hazard communication program covering labels, SDSs, and training.
Compile and maintain a list of the hazardous chemicals present, keyed to their SDSs.
Obtain and retain an SDS for every hazardous chemical, and keep them readily accessible during each shift.
Ensure every shipped and workplace container is labeled per 1910.1200(f).
Train employees at initial assignment and whenever a new chemical hazard is introduced.
Update labels, the written program, SDSs, and training to meet the HCS 2024 (GHS Rev 7) deadlines.

Run it in HazComFast

Every label comes from the product record, so the name on the bottle is the name on the SDS and on your chemical list. GHS workplace labels are included on every plan, the free one too.

Scan the drum, get the sheet

Every line of the inventory prints its own QR code. Stick it on the container, and anyone on the crew scans it with the phone camera to open that product's hazard pictograms, its first-aid steps and the full sheet. No app to install, no account.

Built for jobsites where the signal drops

Your jobsite's SDS load onto the phone on their own. The app shows how many are ready (17 of 20, 20 of 20) before you head underground. First-aid steps for every product on the jobsite stay on the phone, even in airplane mode.

Nothing prints unchecked

Hazard data the AI read from an SDS stays off the labels until someone confirms it. A product with no pictogram, signal word or hazard statement on record is flagged before you print.

2026 penalties for 29 CFR 1910.1200

Maximums set by 29 CFR 1903.15(d). 2026 amounts unchanged from 2025 (no CPI adjustment; OMB M-26-11). Not an increase. The 2025 OSHA penalty levels remain in effect for 2026; OSHA made no inflation adjustment for 2026. 29 CFR 1903.15 identifies January 15, 2025 as the effective reference for these amounts, while OSHA's public penalties page currently references penalties assessed after Jan. 15, 2026.

Violation type	Minimum	Maximum	When it applies
Serious	$1,085	$16,550	Substantial probability of death or serious physical harm.
Other-Than-Serious	$0	$16,550	Relates to safety/health but unlikely to cause death or serious harm.
Willful	$11,823	$165,514	Intentional, knowing, or voluntary disregard of the requirement.
Repeated	$4,256	$165,514	A substantially similar violation cited within the last 5 years.
Failure to Abate	None	$16,550/day	up to $16,550 per day; total capped at 30x the daily amount (FOM Ch.6)

Hazard communication was second on OSHA's list of most-cited standards for FY2025. In construction, federal OSHA cited 1910.1200 698 times that year, and 1926.59, its construction counterpart, 14 times (OSHA's cited-standards tool). A serious violation carries up to $16,550 and a willful or repeat violation up to $165,514, per violation, not per exposed employee.

Maximums and the willful minimum are set by 29 CFR 1903.15(d); the serious and repeated minimums are OSHA policy floors from its annual penalty adjustment memo. OSHA applies gravity-based and size, good-faith and history reductions (FOM CPL 02-00-164 Ch.6). Estimates only, not legal advice.

The business case for HazCom / GHS compliance

HazCom protects workers from the acute and chronic effects of chemical exposure (burns, respiratory sensitization, and long-latency disease) and it underpins every other chemical standard by ensuring workers and emergency responders know what they are handling. It was second on OSHA's FY2025 list of most-cited standards, which says how often the basics are missing.

Frequently asked questions about 29 CFR 1910.1200

What does the OSHA Hazard Communication Standard require?

1910.1200 requires employers to communicate chemical hazards through a written hazard communication program, a list of the hazardous chemicals present, GHS-formatted container labels, Safety Data Sheets (SDS) kept readily accessible during each work shift, and employee training. Chemical manufacturers and importers must classify hazards and prepare compliant labels and 16-section SDSs; downstream employers must maintain the program, labeling, access, and training for the chemicals in their workplace.

Does OSHA require 8 or 9 GHS pictograms?

OSHA requires eight. The GHS defines nine pictograms, but the ninth (the environmental pictogram (GHS09, the dead fish and tree)) covers aquatic/environmental hazards that fall outside OSHA's worker-health jurisdiction, so it is not required on U.S. workplace labels (it is mandatory in the EU under CLP). A HazCom-compliant U.S. label uses the eight health and physical hazard pictograms as applicable.

What has to be in a written hazard communication program?

Under 1910.1200(e), the written program must describe how the employer meets the labeling, SDS, and training requirements, and must include a list of the hazardous chemicals known to be present (keyed to their SDSs) and the methods the employer will use to inform employees of the hazards of non-routine tasks and of chemicals in unlabeled pipes. The program must be available to employees on request.

What does 'readily accessible' mean for SDSs?

Under 1910.1200(g)(8), safety data sheets must be readily accessible to employees during each work shift: meaning workers can get to them without leaving the work area or facing unreasonable delay or barriers. Electronic access is acceptable if devices are available and functional at the worksite, with a reliable backup for system or power failures.

What changed with the HazCom 2024 update?

The 2024 update aligned HazCom with GHS Revision 7, adding hazard classes (such as chemicals under pressure and non-flammable aerosols), refining classification criteria, and revising some label and SDS elements. It did not change the core 16-section SDS format or the eight required pictograms. A January 2026 final rule extended the phased compliance deadlines, giving manufacturers and downstream employers additional time to update labels, programs, SDSs, and training.

Regulatory history of 29 CFR 1910.1200

HazCom was first promulgated in 1983 for the manufacturing sector, expanded to all industries in 1994, and aligned with the Globally Harmonized System (GHS Revision 3) in the landmark 2012 update that introduced standardized labels and the 16-section SDS. The 2024 update (89 FR 44144) aligned it with GHS Revision 7; a January 15, 2026 final rule extended each phased compliance deadline by four months.
