What Is a Hazard Communication Program?

A hazard communication program is the written plan OSHA requires every employer that uses hazardous chemicals to develop, implement, and maintain at each workplace under 29 CFR 1910.1200(e)(1). It must describe how the employer meets the standard’s requirements for labels, safety data sheets, and employee training, and it must include a list of the hazardous chemicals known to be present.

If an OSHA compliance officer walks into your plant, the written program is usually the first document requested. Everything else — container labels, the SDS binder or portal, training records — is checked against what the program says you do. This guide breaks down what the standard actually requires, document by document, and where your chemical supplier fits into the chain.

What must a written hazard communication program contain?

Under 29 CFR 1910.1200(e)(1), employers must develop, implement, and maintain a written program at each workplace. The standard names the elements it has to cover.

Required elementCitationWhat it means in practice
How labels and other forms of warning are handled1910.1200(e)(1)Describes your workplace labeling system and who maintains it
How safety data sheets are handled1910.1200(e)(1)Describes how SDSs are obtained, stored, and made accessible
How employee information and training are handled1910.1200(e)(1)Describes training content, timing, and documentation
A list of the hazardous chemicals known to be present1910.1200(e)(1)(i)Uses the product identifier that appears on the matching SDS; may be site-wide or by work area
Methods for non-routine tasks and unlabeled pipes1910.1200(e)(1)(ii)Covers jobs like vessel cleaning and chemicals in unlabeled piping

The chemical list is where most programs fall apart. OSHA requires the product identifier on the list to match the identifier on the safety data sheet. If purchasing switches suppliers or grades and nobody updates the list, the list and the SDS library drift apart.

How must safety data sheets be kept?

OSHA requires the employer to maintain copies of the required safety data sheets for each hazardous chemical in the workplace, and to ensure they are readily accessible during each work shift to employees when they are in their work areas — 1910.1200(g)(8).

Electronic access is explicitly permitted. The standard allows electronic access and other alternatives to paper copies as long as no barriers to immediate employee access in each workplace are created by such options. A tablet on the production floor is fine. A PDF library that only the EHS manager can log into is not.

For employees who travel between workplaces during a shift, 1910.1200(g)(9) allows the safety data sheets to be kept at the primary workplace facility.

Learn how to read the document itself in our guide to the 16 sections of a safety data sheet.

What must a chemical container label include?

Labels on shipped containers are the supplier’s obligation. Under 1910.1200(f)(1), the chemical manufacturer, importer, or distributor must ensure each container of hazardous chemicals leaving the workplace carries six elements.

#Label elementCitation
1Product identifier1910.1200(f)(1)(i)
2Signal word1910.1200(f)(1)(ii)
3Hazard statement(s)1910.1200(f)(1)(iii)
4Pictogram(s)1910.1200(f)(1)(iv)
5Precautionary statement(s)1910.1200(f)(1)(v)
6Name, U.S. address, and U.S. telephone number of the manufacturer, importer, or other responsible party1910.1200(f)(1)(vi)

Workplace labeling is a separate, looser requirement. Under 1910.1200(f)(6), each container of hazardous chemicals in the workplace must be labeled with either the full shipped-container information, or the product identifier plus words, pictures, or symbols giving general hazard information that works alongside the rest of your program.

Our walkthrough of how to read a GHS label on a chemical drum covers what each element looks like on a real drum.

What must hazard communication training cover?

Training is required at the time of initial assignment and whenever a new chemical hazard employees have not previously been trained about is introduced into their work area — 1910.1200(h)(1). The standard lists four minimum training topics under 1910.1200(h)(3):

  • Methods and observations used to detect the presence or release of a hazardous chemical in the work area, such as employer monitoring, continuous monitoring devices, or visual appearance and odor
  • The physical, health, simple asphyxiation, combustible dust, and pyrophoric gas hazards, plus hazards not otherwise classified, of the chemicals in the work area
  • The measures employees can take to protect themselves, including work practices, emergency procedures, and personal protective equipment
  • The details of the employer’s hazard communication program

Note the trigger: a new chemical hazard, not simply a new product. Swapping one acetone supplier for another does not trigger retraining. Adding a first aromatic solvent to a plant that previously ran only alcohols does.

Where does your chemical supplier fit in?

Three of the documents an auditor asks for originate upstream, with the manufacturer or distributor: the shipped-container label, the safety data sheet, and the certificate of analysis that ties a specific lot to a specific specification. A supplier that is slow with documents becomes your compliance gap.

Practical questions worth asking any distributor before you buy:

  • Is the current SDS available without a login or a phone call?
  • Does the product identifier on the SDS match the label and the invoice line?
  • Is a certificate of analysis issued per lot, and does it reference the same identifier?
  • Does the shipping paperwork carry the correct DOT hazard class and UN number for the material?

RightPath Industries maintains a public SDS library covering the chemicals we distribute, so EHS teams can pull current documents without waiting on a sales rep.

What grades and sizes do we stock?

RightPath Industries distributes more than 8,000 chemicals from our Pittsburgh headquarters, spanning acetates, acids, alcohols, aromatics, bromine chemicals, glycols, high purity analytical solvents, powdered chemicals and salts, and solvents. Common industrial solvents such as acetone ship in gallons, pails, drums, totes, and bulk, packed to your specification and lot-controlled on request.

How do you order from RightPath?

Frequently asked questions

Is a written hazard communication program required for every workplace?

OSHA requires employers to develop, implement, and maintain a written hazard communication program at each workplace where hazardous chemicals are used, under 29 CFR 1910.1200(e)(1). The program is site-specific, so a company with three plants generally maintains three programs.

Can safety data sheets be stored electronically instead of in a binder?

Yes. 29 CFR 1910.1200(g)(8) permits electronic access and other alternatives to paper copies, provided no barriers to immediate employee access are created in each workplace during every work shift.

How often is hazard communication training required?

OSHA requires training at the time of initial assignment and whenever a new chemical hazard that employees have not previously been trained about is introduced into their work area, under 29 CFR 1910.1200(h)(1). The standard does not set a fixed annual interval.

Who is responsible for labeling a drum of solvent that arrives at my plant?

The chemical manufacturer, importer, or distributor is responsible for the label on the shipped container under 29 CFR 1910.1200(f)(1). Once the material is transferred to workplace containers, the employer is responsible for workplace labeling under 1910.1200(f)(6).

Does the chemical list have to match the safety data sheets?

Yes. 29 CFR 1910.1200(e)(1)(i) requires the list of hazardous chemicals to use a product identifier that is referenced on the appropriate safety data sheet.

How Do You Read a Safety Data Sheet (SDS)? All 16 Sections Explained

A safety data sheet (SDS) is a 16-section document that a chemical manufacturer or importer must supply for every hazardous chemical it sells. The sections always appear in the same order, so you read an SDS by jumping to the section that answers your question: Section 2 for hazards, Section 4 for first aid, Section 8 for PPE and exposure limits, Section 14 for shipping classification.

That fixed order is the whole point. OSHA standardized it under the Hazard Communication Standard, 29 CFR 1910.1200, so an EHS manager, a receiving clerk, and an ER physician can each find what they need in seconds without reading the document front to back. This guide breaks down what lives in each section, which ones OSHA actually enforces, what changed under the 2024 HazCom update, and how to get current sheets from your supplier.

What is a safety data sheet, and who has to provide one?

Chemical manufacturers and importers must evaluate the hazards of the chemicals they produce or import and prepare an SDS for each hazardous one. Distributors must pass that SDS down the supply chain. Employers must maintain SDSs for every hazardous chemical in the workplace and keep them readily accessible to employees during each work shift.

Three timing rules govern the paperwork:

  • A supplier must send the SDS with the first shipment of a product to a new customer.
  • When an SDS is revised, the supplier must send the updated sheet with the first shipment after the revision.
  • A manufacturer or importer must update an SDS within three months of learning significant new information about a chemical’s hazards or protective measures.

An SDS is not a certificate of analysis. The SDS describes hazards for a product family; the COA reports the tested results for one specific lot. Buyers in regulated industries need both — see our guide to reading a certificate of analysis.

What are the 16 sections of an SDS?

OSHA fixes the content and order in Appendix D to 1910.1200. Here is what each section holds and who typically uses it.

# Section What it tells you Primary user
1 Identification Product name, recommended use, supplier name, address, emergency phone number Purchasing, receiving
2 Hazard(s) identification GHS hazard classes and categories, signal word, pictograms, hazard and precautionary statements Everyone
3 Composition / information on ingredients Chemical identity, CAS numbers, concentrations or concentration ranges, impurities EHS, toxicology
4 First-aid measures Treatment by exposure route, symptoms, when to get medical help First responders, medical
5 Fire-fighting measures Suitable extinguishing media, specific hazards, protective equipment for firefighters Fire brigade, EHS
6 Accidental release measures Spill containment, cleanup procedures, personal precautions Operations, EHS
7 Handling and storage Safe handling practices, incompatible materials, storage conditions Warehouse, plant
8 Exposure controls / personal protection OSHA PELs, ACGIH TLVs, engineering controls, required PPE EHS, industrial hygiene
9 Physical and chemical properties Appearance, odor, flash point, boiling point, density, vapor pressure, particle characteristics Engineering, process
10 Stability and reactivity Chemical stability, conditions to avoid, incompatible materials, hazardous decomposition Process safety
11 Toxicological information Routes of exposure, acute and chronic effects, LD50/LC50, carcinogenicity listings EHS, medical
12 Ecological information Aquatic and terrestrial toxicity, persistence, bioaccumulation Environmental
13 Disposal considerations Waste handling and disposal guidance, container disposal Waste, environmental
14 Transport information UN number, proper shipping name, hazard class, packing group, marine pollutant status Logistics, shipping
15 Regulatory information Safety, health, and environmental regulations specific to the product Compliance
16 Other information Date of preparation or last revision, revision summary, abbreviation key Document control

Which SDS sections does OSHA actually enforce?

This is the detail most SDS explainers skip. OSHA requires all 16 sections to appear so the format matches the global GHS standard, but OSHA does not enforce the content of Sections 12 through 15. Those sections cover ecological information, disposal, transport, and regulatory status — subject matter that falls under the EPA, the Department of Transportation, and other agencies rather than OSHA.

The practical consequence: Sections 12–15 are useful but not authoritative. If you are classifying a shipment, verify Section 14 against the DOT hazardous materials table rather than treating the SDS as the final word. Our breakdown of DOT hazmat classes for solvents walks through how UN numbers and packing groups are assigned.

Which sections should you read first?

Most people never need all sixteen. Match the section to the question you actually have.

Your question Go to
Can this hurt someone, and how badly? Section 2, then Section 11
What PPE does my team need? Section 8
Is there an exposure limit I have to monitor? Section 8
Can I store this next to that? Section 7, then Section 10
Someone was exposed — what now? Section 4
There is a spill on the dock. Section 6
How do I ship or receive it? Section 14
Is this sheet current? Section 16

Section 16 deserves more attention than it gets. It carries the revision date, and a stale revision date is one of the most common findings in a HazCom audit. Check it before you file the sheet, not after the inspector asks.

What changed under OSHA’s 2024 HazCom update?

OSHA published a final rule on May 20, 2024 aligning the Hazard Communication Standard with Revision 7 of the UN’s Globally Harmonized System. It took effect July 19, 2024. The rule revised SDS Appendix D content in Sections 1, 2, 3, 8, 9, 10, 11, and 14, with the principal GHS-alignment changes falling in Sections 2, 3, 9, and 11.

Two changes matter most to buyers. First, trade-secret concentrations can still be withheld, but Section 3 must now disclose the concentration using one of OSHA’s prescribed ranges — you will no longer see a blank where a percentage should be. Second, Section 9 uses revised physical-property terminology and explicitly addresses particle characteristics.

On January 15, 2026, OSHA extended all HCS 2024 compliance dates by four months. The revised schedule:

Deadline Who What
May 19, 2026 Manufacturers, importers, distributors Updated classifications, labels, and SDSs for substances
November 2026 Employers Workplace labels, written HazCom program, and training for substances
November 2027 Manufacturers, importers, distributors Updated labels and SDSs for mixtures
May 2028 Employers Workplace labels, written program, and training for mixtures

During each transition window, either the 2012 or the 2024 version of the standard is acceptable. Source: OSHA, Final Rule to Amend the Hazard Communication Standard.

How the SDS connects to the drum in front of you

The GHS label on a container is a compressed version of SDS Section 2. Same pictograms, same signal word, same hazard statements — the label is the summary, the SDS is the full record. If a label and an SDS disagree, the SDS revision date tells you which one is out of date. See how to read a GHS label on a chemical drum for the label side of that pairing.

How do you get current SDSs from a distributor?

Ask before you buy. A distributor that cannot produce a current SDS on request is a distributor that will slow down your next audit. RightPath Industries, a Pittsburgh-based bulk chemical distributor supplying 8,000+ chemicals and recognized as a top-10 U.S. ethanol distributor, maintains a public SDS library so buyers and EHS teams can pull documentation without opening a support ticket. Lot-specific COAs ship with the order.

When you evaluate any supplier’s documentation, check four things: the SDS reflects the most recent significant hazard update, the revision date in Section 16 is legible, Section 3 discloses concentrations or OSHA-permitted ranges, and the emergency phone number in Section 1 is answered around the clock.

Frequently asked questions

How many sections does a safety data sheet have?

A safety data sheet has exactly 16 sections. The number, order, and headings are fixed by OSHA in Appendix D to 29 CFR 1910.1200 and match the UN GHS format used internationally.

What is the difference between an MSDS and an SDS?

An MSDS (material safety data sheet) was the pre-2012 U.S. format, which had no required section order and varied by manufacturer. OSHA replaced it with the 16-section SDS when it aligned HazCom with GHS in 2012. Any sheet still labeled MSDS is out of date and should be replaced.

Which SDS sections are most important for worker safety?

Section 2 and Section 8. Section 2 states what the chemical can do to a person, and Section 8 states the exposure limits and personal protective equipment required to prevent it. Section 4 is the third priority because it governs the response after an exposure occurs.

How often must a safety data sheet be updated?

There is no fixed calendar interval. A chemical manufacturer or importer must revise the SDS within three months of becoming aware of significant new information about the chemical’s hazards or ways to protect against them, and must send the revised sheet with the next shipment to customers who received the product in the prior twelve months.

Does an SDS replace a certificate of analysis?

No. An SDS covers hazard and handling information for a product as a whole and does not change lot to lot. A COA reports the measured test results for one specific production lot. Pharmaceutical, food, and laboratory buyers generally require both documents on every shipment.

Which SDS section has the flash point?

Section 9, Physical and chemical properties. That section also carries physical state, odor, pH, melting and boiling point, flammability, vapor pressure, relative density, solubility, and viscosity.

Which SDS section has the UN number and shipping name?

Section 14, Transport information. It lists the UN number, UN proper shipping name, transport hazard class, packing group, environmental hazards, and any special precautions. Section 14 is non-mandatory under OSHA, but virtually all suppliers populate it because shippers need it.

Can we keep SDSs electronically instead of in binders?

Yes. OSHA explicitly permits electronic access and other alternatives to paper copies, as long as no barriers to immediate employee access are created in each workplace. Employees must be able to reach the sheet during their shift, in their work area, without waiting for someone else.

How Do You Read a GHS Label on a Chemical Drum?

How do you read a GHS label on a chemical drum?

To read a GHS label, check its six required elements: the product identifier, a signal word (“Danger” or “Warning”), hazard statements (H-codes), precautionary statements (P-codes), hazard pictograms, and the supplier’s contact information. Together these tell you what the chemical is, how severe its hazards are, what harm it can cause, and how to handle it safely. In the United States, GHS labeling is required by the OSHA Hazard Communication Standard (29 CFR 1910.1200).

What are the six required elements of a GHS label?

Every GHS-compliant shipped container label carries the same six parts. Reading them in order tells you the identity and hazards of the chemical inside.

Label element What it tells you
Product identifier The chemical name or number, matching the safety data sheet (SDS)
Signal word Relative severity: “Danger” (more severe) or “Warning” (less severe)
Hazard statements (H-codes) Standardized phrases describing the hazard, e.g. H314 “Causes severe skin burns and eye damage”
Precautionary statements (P-codes) Steps for safe handling, storage, first aid, and disposal
Pictograms Red-bordered diamonds showing hazard type at a glance
Supplier identification Name, address, and phone number of the manufacturer or distributor
Required by OSHA HazCom (29 CFR 1910.1200), aligned with the UN GHS.

What do the GHS pictograms mean?

GHS uses nine pictograms—red-bordered white diamonds with black symbols. Each maps to a class of physical, health, or environmental hazard.

Pictogram Hazard it signals
Flame Flammable liquids, solids, gases, and aerosols
Corrosion Skin/eye corrosion and materials corrosive to metals
Exclamation mark Irritant, skin sensitizer, acute toxicity (harmful), narcotic effects
Health hazard Carcinogen, respiratory sensitizer, reproductive or organ toxicity
Skull and crossbones Acute toxicity (fatal or toxic)
Flame over circle Oxidizers
Gas cylinder Gases under pressure
Exploding bomb Explosives, self-reactives, organic peroxides
Environment Aquatic toxicity (not mandatory under OSHA HazCom)

What is the difference between “Danger” and “Warning” on a GHS label?

The signal word ranks severity. “Danger” is used for the more severe hazard categories; “Warning” is used for the less severe ones. A label carries only one signal word—the highest one that applies. If you see “Danger,” treat the chemical with the strictest precautions its statements call for.

How do you read a GHS label step by step?

  1. Confirm the product identifier and match it to the correct SDS.
  2. Read the signal word to gauge overall severity.
  3. Scan the pictograms to see the hazard types at a glance.
  4. Read every hazard (H) statement to learn the specific dangers.
  5. Follow the precautionary (P) statements for handling, PPE, storage, and first aid.
  6. Note the supplier information for emergency contact and reordering.

What are H-codes and P-codes on a GHS label?

Hazard statements and precautionary statements are standardized, numbered phrases so the same code means the same thing worldwide. H-codes (hazard statements) describe the nature and, where relevant, the degree of the hazard—for example, H314 means “Causes severe skin burns and eye damage.” P-codes (precautionary statements) tell you what to do about it, grouped into prevention, response, storage, and disposal—for example, P280 means “Wear protective gloves/eye protection.” Reading the H-codes tells you the risk; following the P-codes tells you how to work safely.

What should you do if a GHS label is missing or damaged?

Do not use or transfer a chemical from a container whose label is missing, defaced, or illegible. Under OSHA HazCom, shipped containers must arrive labeled; if one does not, quarantine it and contact the supplier for a replacement label and SDS. For in-plant containers, relabel using the product’s SDS information before the material is used. Never rely on memory or an unlabeled container to identify a hazardous chemical.

Do workplace (secondary) containers need GHS labels?

Yes, with one narrow exception. When you transfer a chemical into a secondary container, it must be labeled with the product identifier and hazard information. OSHA allows an exception only when the chemical is transferred for the immediate use of the worker who made the transfer and is used up within that shift. Otherwise, the workplace container needs either the full GHS label or an approved alternative in-house labeling system.

Worked example: what does the GHS label on glacial acetic acid say?

Using glacial acetic acid as an example, the GHS classification (per PubChem) is:

  • Signal word: Danger
  • Pictograms: Flame and Corrosion
  • H226: Flammable liquid and vapor
  • H314: Causes severe skin burns and eye damage

That label tells a handler, at a glance, that glacial acetic acid is both flammable and corrosive and must be kept from ignition sources while workers wear chemical-resistant PPE. Always follow the precautionary statements and the full SDS for exposure, storage, and spill guidance rather than the label alone. See related products in the acids category.

How do you order labeled, SDS-backed chemicals from RightPath?

Frequently asked questions

What are the six elements of a GHS label?

Product identifier, signal word, hazard statements, precautionary statements, pictograms, and supplier identification. All six are required on a GHS-compliant shipped container label.

Is a GHS label the same as a safety data sheet?

No. The GHS label is the summary printed on the container. The safety data sheet (SDS) is a separate 16-section document with full details on handling, exposure limits, storage, and emergency response.

How many GHS pictograms are there?

There are nine GHS pictograms. Eight are mandatory under OSHA HazCom; the Environment (aquatic toxicity) pictogram is not required by OSHA but is used internationally.

What GHS hazards apply to glacial acetic acid?

Glacial acetic acid carries the signal word “Danger,” the Flame and Corrosion pictograms, and hazard statements H226 (flammable liquid and vapor) and H314 (causes severe skin burns and eye damage), per PubChem.

Who is required to put GHS labels on chemical containers?

Under OSHA’s Hazard Communication Standard, chemical manufacturers, importers, and distributors must label shipped containers with GHS elements. Employers must keep those labels legible and ensure workplace containers are labeled.
