Huge OSHA HazCom rule likely impacts YOU
OSHA’s Hazard Communication (HazCom) final rule made its appearance on May 20 with a TON of changes. In fact, updates stirred up almost everything — definitions, hazard classifications, labeling, safety data sheets (SDSs), training, and trade secrets! The agency plans to post a redline version of the rule that compares the old to the new text of 29 CFR 1910.1200. However, until then, if you’re wondering how the rule affects your operations, please read on.
New and revised definitions
The rule adds and revises definitions and removes one.
New | Revised | Removed |
• Bulk shipment • Combustible dust • Gas • Immediate outer package • Liquid • Physician or other licensed health care professional (PLHCP) • Released for shipment • Solid | • Exposure or exposed • Hazardous chemical • Physical hazard | • Pyrophoric gas |
Hazard classification
Manufacturers and importers must reclassify aerosols, desensitized explosives, and flammable gases under new criteria in Appendix B to 1910.1200. They also need to make corresponding revisions to SDSs and labels. Moreover:
- Appendix A includes revised health hazard definitions, updated skin corrosion/irritation and serious eye damage/eye irritation chapters, and general updates to hazard classes;
- Appendix B has other changes to the physical hazard criteria; and
- Appendix C contains labeling element guidance and clarification around precautionary and hazard statements for several classifications.
Hazard classification must include any hazards associated with the chemical’s intrinsic properties. This covers a change in the chemical’s physical form, and chemical reactions with products from known or reasonably anticipated uses or applications.
Labels for packages released for shipment
When new or significant information about a chemical’s hazards becomes known, chemical manufacturers, distributors, or importers still have six months to update the corresponding labels. What’s new is the option to NOT relabel chemicals already released for shipment and awaiting further distribution. With this option, however, chemical manufacturers, distributors, or importers must provide the updated label for each individual container with each shipment.
Labels for bulk shipments
Bulk shipments are hazardous chemicals transported where the mode of transportation IS the immediate container. This includes shipments via tanker truck, rail car, or intermodal container. According to the rule, labels for bulk shipments must be:
- On the immediate container,
- Transmitted with the shipping papers or the bills of lading, or
- Transmitted by technological or electronic means (if agreed to by the receiving entity).
OSHA pictograms are not required when a pictogram for the same hazard is already required by the Department of Transportation to be on a shipped container.
Labels for small containers
For shipped containers, chemical manufacturers, importers, or distributors can often demonstrate that it’s not feasible to use pull-out labels, fold-back labels, or tags with the full label information. If that’s the case, they have some labeling alternatives depending on the size of the container:
Containers less than or equal to: | Must: | And the immediate outer package must include both: |
100 ml capacity | Include the product identifier, pictogram(s), signal word, chemical manufacturer’s contact information, and a statement that the full label information is provided on the immediate outer package | • The full label information for each hazardous chemical in the immediate outer package, and • A statement that the small container(s) inside must be stored in the immediate outer package bearing the complete label when not in use. |
3 ml capacity | Provide at least the product identifier where chemical manufacturers, importers, or distributors demonstrate that any label interferes with the normal use of the container |
Labels for in-house containers
Employers must update any alternative inhouse labeling systems for substances and mixtures by the compliance dates listed at 1910.1200(j).
SDSs
OSHA changed the subsections required on the SDS by adding, removing, or altering subsections within:
- Section 1, Identification
- Section 2, Hazard(s) identification
- Section 3, Composition/information on ingredients
- Section 8, Exposure controls/personal protection
- Section 9, Physical and chemical properties
- Section 10, Stability and reactivity
- Section 11, Toxicological information
- Section 14, Transport information (non-mandatory)
OSHA also clarifies that while each section of the SDS must contain all the specified information, it’s not required to be in any particular order within each section.
Training
Employers must update their training programs and provide employee training for substances and mixtures by the two compliance dates at 1910.1200(j), as necessary.
Trade secrets
Trade secret means any confidential formula, pattern, process, device, information, or compilation of information used in an employer’s business. Under the new rule, manufacturers, importers, and employers can withhold a chemical’s concentration range as a trade secret on the SDS. Also, when the actual range is claimed as a trade secret, prescriptive concentration ranges must be used.
Important dates
Finally, the rule provides five important dates:
Compliance date | Requirement(s) | Who |
July 19, 2024 | Effective date of rule | All covered entities |
January 19, 2026 | For substances, comply with all modified provisions of 1910.1200 | Chemical manufacturers, importers, and distributors evaluating substances |
July 20, 2026 | For substances, as necessary: • Update any alternative workplace (inhouse) labeling, • Update HazCom training program, and • Provide additional employee training for newly identified physical, health, or other hazards covered | Employers |
July 19, 2027 | For mixtures, comply with all modified provisions of 1910.1200 | Chemical manufacturers, importers, and distributors evaluating mixtures |
January 19, 2028 | For mixtures, as necessary: • Update any alternative workplace (inhouse) labeling, • Update the HazCom training program, and • Provide additional employee training for newly identified physical, health, and other hazards covered | Employers |
Transition period from May 20, 2024, to respective compliance date above, as applicable | Comply with either: • 1910.1200 newly revised as of July 19, 2024; • Former 1910.1200 as of July 1, 2023; or • Both | Chemical manufacturers, importers, distributors, and employers |
Key to Remember: OSHA’s final HazCom rule changes almost everything! However, employers have fewer impacts.
