OSHA hazard communication study guide
OSHA's construction rules at 29 CFR 1926.59 say the hazard communication requirements for construction work are identical to 29 CFR 1910.1200, the Hazard Communication Standard. This guide sets out what that rule text states on scope, key definitions, the written hazard communication program, labels, safety data sheets, employee information and training, trade secrets and the dates of the 2024 revision. The detailed hazard classification criteria in Appendices A and B are not summarized. Every point links to the regulation and quotes its exact words, as revised in 2024; until the compliance dates in 1910.1200(j), the version revised as of July 1, 2023 may also be followed. It is an independent study aid, not OSHA training.
Scope and construction coverage
Part 1926 does not repeat the hazard communication rules. Section 1926.59 says the requirements for construction work are identical to those in 29 CFR 1910.1200.
“The requirements applicable to construction work under this section are identical to those set forth at § 1910.1200 of this chapter.”
The standard's purpose is to make sure the hazards of all chemicals produced or imported are classified and that information about those hazards reaches employers and employees.
“The purpose of this section is to ensure that the hazards of all chemicals produced or imported are classified, and that information concerning the classified hazards is transmitted to employers and employees.”
As revised in 2024, the rule is intended to be consistent with the United Nations Globally Harmonized System (GHS), primarily Revision 7. Information is passed on through hazard communication programs that include container labels and other warnings, safety data sheets and employee training. (Current text of the section as revised in 2024; until the applicable compliance date in 1910.1200(j), the version revised as of July 1, 2023 may be followed instead.)
“The requirements of this section are intended to be consistent with the provisions of the United Nations Globally Harmonized System of Classification and Labeling of Chemicals (GHS), primarily Revision 7. The transmittal of information is to be accomplished by means of comprehensive hazard communication programs, which are to include container labeling and other forms of warning, safety data sheets and employee training.”
Employers who do not produce or import chemicals need only focus on the parts of the rule about setting up a workplace program and communicating information to their workers.
“Employers who do not produce or import chemicals need only focus on those parts of this rule that deal with establishing a workplace program and communicating information to their workers.”
The standard applies to any chemical known to be present in the workplace in a way that employees may be exposed under normal conditions of use or in a foreseeable emergency.
“This section 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 does not apply to wood or wood products, including lumber which will not be processed, where the chemical manufacturer or importer can establish that the only hazard to employees is the potential for flammability or combustibility. Wood or wood products treated with a hazardous chemical covered by the standard, and wood which may later be sawed or cut, generating dust, are not exempted.
“Wood or wood products, including lumber which will not be processed, where the chemical manufacturer or importer can establish that the only hazard they pose to employees is the potential for flammability or combustibility (wood or wood products which have been treated with a hazardous chemical covered by this standard, and wood which may be subsequently sawed or cut, generating dust, are not exempted)”
A consumer product or hazardous substance (as defined in the Consumer Product Safety Act and the Federal Hazardous Substances Act) is outside the standard only where the employer can show it is used in the workplace for the purpose intended by the chemical manufacturer or importer, and the duration and frequency of exposure are not greater than the range consumers could reasonably experience when using it for that purpose.
“where the employer can show that it is used in the workplace for the purpose intended by the chemical manufacturer or importer of the product, and the use results in a duration and frequency of exposure which is not greater than the range of exposures that could reasonably be experienced by consumers when used for the purpose intended”
Chemical manufacturers and importers must evaluate the chemicals they produce or import to classify them. Other employers are not required to classify chemicals unless they choose not to rely on the classification performed by the chemical manufacturer or importer.
“Chemical manufacturers and importers shall evaluate chemicals produced in their workplaces or imported by them to classify the chemicals in accordance with this section. Employers are not required to classify chemicals unless they choose not to rely on the classification performed by the chemical manufacturer or importer for the chemical to satisfy this paragraph (d)(1).”
Not covered here
The labeling exemptions in 1910.1200(b)(5) and the other exclusions in (b)(6) (pesticides, food, drugs, hazardous waste and others, each with its own conditions), the limited rules for laboratories and sealed-container operations, and the classification criteria in mandatory Appendices A and B. We only write what an official source states, so study these parts with your certifying program's materials.
Key definitions
A hazardous chemical is any chemical classified as a physical hazard or a health hazard, a simple asphyxiant, combustible dust, or a hazard not otherwise classified. (Current text of the section as revised in 2024; until the applicable compliance date in 1910.1200(j), the version revised as of July 1, 2023 may be followed instead.)
“Hazardous chemical means any chemical which is classified as a physical hazard or a health hazard, a simple asphyxiant, combustible dust, or hazard not otherwise classified.”
An employer is anyone in a business where chemicals are used, distributed or produced, and the definition expressly includes contractors and subcontractors.
“Employer means a person engaged in a business where chemicals are either used, distributed, or are produced for use or distribution, including a contractor or subcontractor.”
An employee is a worker who may be exposed under normal operating conditions or in foreseeable emergencies. Workers such as office workers who meet hazardous chemicals only in non-routine, isolated instances are not covered.
“Employee means a worker who may be exposed to hazardous chemicals under normal operating conditions or in foreseeable emergencies. Workers such as office workers or bank tellers who encounter hazardous chemicals only in non-routine, isolated instances are not covered.”
Exposure includes potential (accidental or possible) exposure, and for health hazards any route of entry: inhalation, ingestion, skin contact or absorption.
“Exposure or exposed means that an employee is subjected in the course of employment to a hazardous chemical, and includes potential (e.g., accidental or possible) exposure. "Subjected" in terms of health hazards includes any route of entry (e.g., inhalation, ingestion, skin contact or absorption.)”
A foreseeable emergency is any potential occurrence, such as equipment failure, rupture of containers or failure of control equipment, that could result in an uncontrolled release of a hazardous chemical into the workplace.
“Foreseeable emergency means any potential occurrence such as, but not limited to, equipment failure, rupture of containers, or failure of control equipment which could result in an uncontrolled release of a hazardous chemical into the workplace.”
A container is any bag, barrel, bottle, box, can, cylinder, drum, reaction vessel, storage tank or the like that contains a hazardous chemical. Pipes and piping systems, and engines, fuel tanks or other operating systems in a vehicle, are not containers under this section.
“Container means any bag, barrel, bottle, box, can, cylinder, drum, reaction vessel, storage tank, or the like that contains a hazardous chemical. For purposes of this section, pipes or piping systems, and engines, fuel tanks, or other operating systems in a vehicle, are not considered to be containers.”
A workplace can be an establishment, a job site or a project at one geographical location, containing one or more work areas.
“Workplace means an establishment, job site, or project, at one geographical location containing one or more work areas.”
The product identifier is the name or number used for a hazardous chemical on a label or in the SDS. It must allow cross-references among the written program's chemical list, the label and the SDS.
“Product identifier means the name or number used for a hazardous chemical on a label or in the SDS. It provides a unique means by which the user can identify the chemical. The product identifier used shall permit cross-references to be made among the list of hazardous chemicals required in the written hazard communication program, the label and the SDS.”
Not covered here
The definitions of each physical and health hazard class; their criteria are in mandatory Appendices A and B to 1910.1200. We only write what an official source states, so study these parts with your certifying program's materials.
Written hazard communication program
Employers must develop, implement and maintain a written hazard communication program at each workplace. It must at least describe how the label, safety data sheet and training requirements will be met.
“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”
The program must include a list of the hazardous chemicals known to be present, using a product identifier referenced on the SDS. The list may cover the whole workplace or individual work areas.
“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)”
The program must also include how the employer will inform employees of the hazards of non-routine tasks and of chemicals in unlabeled pipes in their work areas.
“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.”
On multi-employer workplaces, employers who produce, use or store hazardous chemicals so that employees of other employers may be exposed (the rule's example: employees of a construction contractor working on-site) must add to their program the methods they will use to give those other employers on-site access to the SDSs.
“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: (i) The methods the employer will use to provide the other employer(s) on-site access to safety data sheets”
The multi-employer program must also cover how the other employers will be told about precautionary measures needed in normal operating conditions and foreseeable emergencies, and about the labeling system used in the workplace.
“The methods the employer will use to inform the other employer(s) of any precautionary measures that need to be taken to protect employees during the workplace's normal operating conditions and in foreseeable emergencies; and, (iii) The methods the employer will use to inform the other employer(s) of the labeling system used in the workplace.”
The written program must be made available on request to employees, their designated representatives, the Assistant Secretary (OSHA) and the Director (NIOSH), in accordance with 29 CFR 1910.1020(e).
“The employer shall make the written hazard communication program available, upon request, to employees, their designated representatives, the Assistant Secretary and the Director, in accordance with the requirements of § 1910.1020(e).”
Where employees travel between workplaces during a workshift (work at more than one geographical location), the written program may be kept at the primary workplace facility.
“Where employees must travel between workplaces during a workshift, i.e., their work is carried out at more than one geographical location, the written hazard communication program may be kept at the primary workplace facility.”
Labels and other forms of warning
Where the chemical manufacturer, importer or distributor must label, tag or mark a container, the label must show the product identifier, signal word, hazard statement(s), pictogram(s), precautionary statement(s), and the name, U.S. address and U.S. telephone number of the chemical manufacturer, importer or other responsible party. (Current text of the section as revised in 2024; until the applicable compliance date in 1910.1200(j), the version revised as of July 1, 2023 may be followed instead.)
“Where the chemical manufacturer, importer, or distributor is required to label, tag or mark the following shall be provided: (i) Product identifier; (ii) Signal word; (iii) Hazard statement(s); (iv) Pictogram(s); (v) Precautionary statement(s); (vi) Name, U.S. address, and U.S. telephone number of the chemical manufacturer, importer, or other responsible party.”
The signal words are "danger" and "warning": "danger" for the more severe hazards, "warning" for the less severe.
“The signal words used in this section are "danger" and "warning." "Danger" is used for the more severe hazards, while "warning" is used for the less severe.”
Mandatory Appendix C: if "Danger" is on the label, "Warning" must not appear.
“If the signal word "Danger" is included, the signal word "Warning" shall not appear;”
Mandatory Appendix C: a pictogram is a square set at a point, with a black hazard symbol on a white background and a red frame wide enough to be clearly visible. A red frame without a hazard symbol is not a pictogram and is not permitted on the label. Each pictogram uses one of eight standard hazard symbols.
“Pictograms shall be in the shape of a square set at a point and shall include a black hazard symbol on a white background with a red frame sufficiently wide to be clearly visible. A square red frame set at a point without a hazard symbol is not a pictogram and is not permitted on the label. C.2.3.2 One of eight standard hazard symbols shall be used in each pictogram.”
Except as provided in (f)(7) and (f)(8), each container of hazardous chemicals in the workplace must be labeled, tagged or marked with either the shipped-container label information in (f)(1)(i) through (v) (product identifier, signal word, hazard statements, pictograms and precautionary statements), or the product identifier plus words, pictures or symbols giving at least general hazard information, which together with the other information immediately available under the program gives employees the specific physical and health hazard information.
“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: (i) The information specified under paragraphs (f)(1)(i) through (v) of this section for labels on shipped containers; or, (ii) Product identifier and words, pictures, symbols, or combination thereof, which provide at least general information regarding the hazards of the chemicals, and which, in conjunction with the other information immediately available to employees under the hazard communication program, will provide employees with the specific information regarding the physical and health hazards of the hazardous chemical.”
For individual stationary process containers, signs, placards, process sheets, batch tickets, operating procedures or similar written materials may be used instead of labels, if they identify the containers and convey the information (f)(6) requires on a label. The written materials must be readily accessible to employees in their work area throughout each work shift.
“The employer may use signs, placards, process sheets, batch tickets, operating procedures, or other such written materials in lieu of affixing labels to individual stationary process containers, as long as the alternative method identifies the containers to which it is applicable and conveys the information required by paragraph (f)(6) of this section to be on a label. The employer shall ensure the written materials are readily accessible to the employees in their work area throughout each work shift.”
The employer is not required to label portable containers filled from labeled containers if they are intended only for the immediate use of the employee who performs the transfer.
“The employer is not required to label portable containers into which hazardous chemicals are transferred from labeled containers, and which are intended only for the immediate use of the employee who performs the transfer.”
Immediate use means the hazardous chemical is under the control of, and used only by, the person who transfers it from a labeled container, and only within the work shift in which it is transferred. (Current text of the section as revised in 2024; until the applicable compliance date in 1910.1200(j), the version revised as of July 1, 2023 may be followed instead.)
“Immediate use means that the hazardous chemical will be under the control of and used only by the person who transfers it from a labeled container and only within the work shift in which it is transferred.”
Existing labels on incoming containers must not be removed or defaced unless the container is immediately marked with the required information.
“The employer shall not remove or deface existing labels on incoming containers of hazardous chemicals, unless the container is immediately marked with the required information.”
Workplace labels or other forms of warning must be legible, in English, and prominently displayed on the container or readily available in the work area throughout each work shift. Information in other languages may be added as long as it is also in English.
“The employer shall ensure that workplace labels or other forms of warning are legible, in English, and prominently displayed on the container, or readily available in the work area throughout each work shift. Employers having employees who speak other languages may add the information in their language to the material presented, as long as the information is presented in English as well.”
Chemical manufacturers, importers, distributors or employers who become newly aware of significant information about a chemical's hazards must revise the labels within six months.
“Chemical manufacturers, importers, distributors, or employers who become newly aware of any significant information regarding the hazards of a chemical shall revise the labels for the chemical within six months of becoming aware of the new information”
Not covered here
The full hazard-by-hazard label elements in Appendix C.4, the small-container labeling rules in (f)(12), and the transportation and bulk-shipment rules in (f)(5). We only write what an official source states, so study these parts with your certifying program's materials.
Safety data sheets
Chemical manufacturers and importers must obtain or develop an SDS for each hazardous chemical they produce or import. Employers must have an SDS in the workplace for each hazardous chemical they use.
“Chemical manufacturers and importers shall obtain or develop a safety data sheet for each hazardous chemical they produce or import. Employers shall have a safety data sheet in the workplace for each hazardous chemical which they use.”
The chemical manufacturer or importer must make sure the SDS is in English (the employer may keep copies in other languages as well) and includes at least these section numbers and headings, with the associated information under each heading, in the order listed, starting with Section 1 Identification through Section 8 Exposure controls/personal protection.
“The chemical manufacturer or importer shall ensure that the safety data sheet is in English (although the employer may maintain copies in other languages as well), and includes at least the following section numbers and headings, and associated information under each heading, in the order listed (see appendix D to this section, for the specific content of each section of the safety data sheet): (i) Section 1, Identification; (ii) Section 2, Hazard(s) identification; (iii) Section 3, Composition/information on ingredients; (iv) Section 4, First-aid measures; (v) Section 5, Fire-fighting measures; (vi) Section 6, Accidental release measures; (vii) Section 7, Handling and storage; (viii) Section 8, Exposure controls/personal protection;”
The list continues with Sections 9 to 16, ending with Section 16, Other information, which includes the date of preparation or last revision.
“Section 9, Physical and chemical properties; (x) Section 10, Stability and reactivity; (xi) Section 11, Toxicological information. (xii) Section 12, Ecological information; (xiii) Section 13, Disposal considerations; (xiv) Section 14, Transport information; (xv) Section 15, Regulatory information; and (xvi) Section 16, Other information, including date of preparation or last revision.”
To be consistent with the GHS, an SDS must also include the headings for Sections 12 to 15 in order, but OSHA will not enforce the information requirements in Sections 12 to 15 because those areas are not under its jurisdiction.
“To be consistent with the GHS, an SDS must also include the headings in paragraphs (g)(2)(xii) through (g)(2)(xv) of this section in order. Note 2 to paragraph (g)(2): OSHA will not be enforcing information requirements in sections 12 through 15, as these areas are not under its jurisdiction.”
If no relevant information is found for a sub-heading, the preparer must mark the SDS to show that no applicable information was found.
“If no relevant information is found for any sub-heading within a section on the safety data sheet, the chemical manufacturer, importer or employer preparing the safety data sheet shall mark it to indicate that no applicable information was found.”
If the preparer of the SDS becomes newly aware of significant information about a chemical's hazards, or ways to protect against them, the new information must be added to the SDS within three months. If the chemical is not currently being produced or imported, the manufacturer or importer must add the information before the chemical is introduced into the workplace again.
“this new information shall be added to the safety data sheet within three months. If the chemical is not currently being produced or imported, the chemical manufacturer or importer shall add the information to the safety data sheet before the chemical is introduced into the workplace again.”
Employers must keep copies of the required SDSs in the workplace and make them readily accessible to employees in their work areas during each work shift. Electronic access is allowed if it creates no barriers to immediate employee access.
“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.)”
Where employees travel between workplaces during a workshift, SDSs may be kept at the primary workplace facility, but employees must be able to get the information immediately in an emergency.
“Where employees must travel between workplaces during a workshift, i.e., their work is carried out at more than one geographical location, the safety data sheets may be kept at the primary workplace facility. In this situation, the employer shall ensure that employees can immediately obtain the required information in an emergency.”
Not covered here
The detailed content of each SDS section in Table D.1 of Appendix D, and the distributor and retail rules for passing on SDSs in (g)(6) and (g)(7). We only write what an official source states, so study these parts with your certifying program's materials.
Employee information and training
Employers must give effective information and training on hazardous chemicals in the work area at initial assignment and whenever a new chemical hazard the employees have not been trained on is introduced.
“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.”
Training may cover categories of hazards (such as flammability or carcinogenicity) or specific chemicals, but chemical-specific information must always be available through labels and SDSs.
“Information and training may be designed to cover categories of hazards (e.g., flammability, carcinogenicity) or specific chemicals. Chemical-specific information must always be available through labels and safety data sheets.”
Employees must be informed of the requirements of the standard, operations in their work area where hazardous chemicals are present, and where the written program, chemical list and SDSs are and how to get them.
“Employees shall be informed of: (i) The requirements of this section; (ii) Any operations in their work area where hazardous chemicals are present; and, (iii) The location and availability of the written hazard communication program, including the required list(s) of hazardous chemicals, and safety data sheets required by this section.”
Training must include methods and observations to detect the presence or release of a hazardous chemical, such as employer monitoring, continuous monitoring devices, or the look or smell of a chemical being released.
“Methods and observations that may be used to detect the presence or release of a hazardous chemical in the work area (such as monitoring conducted by the employer, continuous monitoring devices, visual appearance or odor of hazardous chemicals when being released, etc.);”
Training must cover the physical, health, simple asphyxiation, combustible dust and pyrophoric gas hazards, and hazards not otherwise classified, of the chemicals in the work area, and the protective measures employees can take, including the employer's work practices, emergency procedures and personal protective equipment.
“The physical, health, simple asphyxiation, combustible dust, and pyrophoric gas hazards, as well as hazards not otherwise classified, of the chemicals in the work area; (iii) The measures employees can take to protect themselves from these hazards, including specific procedures the employer has implemented to protect employees from exposure to hazardous chemicals, such as appropriate work practices, emergency procedures, and personal protective equipment to be used”
Training must explain the employer's program, including labels on shipped containers, the workplace labeling system, and the SDS, including the order of information and how to obtain and use it.
“The details of the hazard communication program developed by the employer, including an explanation of the labels received on shipped containers and the workplace labeling system used by their employer; the safety data sheet, including the order of information and how employees can obtain and use the appropriate hazard information.”
Trade secrets
A manufacturer, importer or employer may withhold the specific chemical identity, and/or the exact percentage (concentration) or concentration range of a substance in a mixture, from Section 3 of the SDS as a trade secret only under the conditions in (i)(1). These include that the claim can be supported, that the SDS discloses the chemical's properties and effects, and that the SDS says the identity and/or concentration or concentration range is being withheld as a trade secret. (Current text of the section as revised in 2024; until the applicable compliance date in 1910.1200(j), the version revised as of July 1, 2023 may be followed instead.)
“The claim that the information withheld is a trade secret can be supported; (ii) Information contained in the safety data sheet concerning the properties and effects of the hazardous chemical is disclosed; (iii) The safety data sheet indicates that the specific chemical identity and/or concentration or concentration range of composition is being withheld as a trade secret;”
In a medical emergency, where a treating PLHCP determines the specific chemical identity and/or concentration or concentration range is needed for emergency or first-aid treatment, the trade secret identity or percentage composition must be disclosed to that PLHCP immediately, even without a written statement of need or confidentiality agreement. (Current text of the section as revised in 2024; until the applicable compliance date in 1910.1200(j), the version revised as of July 1, 2023 may be followed instead.)
“shall immediately disclose the specific chemical identity or percentage composition of a trade secret chemical to that treating PLHCP, regardless of the existence of a written statement of need or a confidentiality agreement.”
A denial of a written (non-emergency) request for disclosure must be given within thirty days of the request, in writing, with evidence and specific reasons.
“Be provided to the health professional, employee, or designated representative, within thirty days of the request; (ii) Be in writing; (iii) Include evidence to support the claim that the specific chemical identity or percent of composition is a trade secret; (iv) State the specific reasons why the request is being denied;”
Not covered here
The prescribed concentration ranges in (i)(1)(iv), the rest of the non-emergency request process in (i)(3) to (i)(13), and the trade secret criteria in mandatory Appendix E. We only write what an official source states, so study these parts with your certifying program's materials.
