A compliant SDS management system gives every employee immediate, no-barriers access to the manufacturer's current 16-section Safety Data Sheet for every hazardous chemical they may be exposed to during a shift — with a paper or alternate-access backup if the primary system goes down. Under the May 2024 update to the Hazard Communication Standard (29 CFR 1910.1200), SDSs must conform to GHS Revision 7, manufacturers and importers must update labels and SDSs by May 19, 2026, and downstream employers must update workplace labeling, written programs, and training by November 20, 2026.
Manufacturing safety teams running multi-site GHS Rev 7 chemical inventories should be doing the SDS-library cutover work now, not at the November deadline.
What Does the 2024 HazCom Update Actually Change?
OSHA published the final rule modifying the HCS on May 20, 2024, with an effective date of July 19, 2024. The headline change is alignment with GHS Revision 7, which updates hazard classification criteria, sharpens the precautionary statement language, and tightens the 16-section SDS format that became mandatory under the original 2012 GHS adoption. The 16-section format is unchanged in structure — Section 1 identification, Section 2 hazard identification, Section 3 composition, Section 4 first-aid, Section 8 exposure controls and PPE, Section 11 toxicological information, Section 16 other — but the content rules underneath got tightened.
Three classification changes employers should know about: aerosols now include "chemicals under pressure" as a defined hazard class, desensitized explosives have a clearer classification path, and skin and eye irritation categories were refined. Concentration cutoff values for several health hazards moved. The result, in practice, is that a non-trivial share of currently-shelved SDSs will need to be reissued by manufacturers before May 19, 2026, and employers will receive a wave of revised SDSs to file. The HazCom: Safety Data Sheets for Employees course covers the GHS Rev 7 changes from the worker's perspective; the HazCom: Safety Data Sheets for Supervisors course covers the manager-track version.
For background on the 16-section format itself, the SDS sections walkthrough — find hazards fast during incident covers how a worker reads an SDS during an emergency. The hazard communication basics for workers explains the GHS framework underneath.
How Should Employees Access the SDS Library?
1910.1200(g)(8) requires that SDSs be "readily accessible during each work shift to employees when they are in their work area(s)." OSHA has accepted electronic access — a tablet, a wall-mounted kiosk, a shared computer — as long as four conditions are met. First, employees know the system exists and have been trained to use it. Second, there are no barriers — no per-use login that requires IT support, no required password rotation that locks workers out, no system that requires a supervisor to print a sheet on demand. Third, there is a backup if the primary system fails, typically a paper copy of the active chemical inventory's SDSs kept in a binder at a known location. Fourth, the SDSs available are the current manufacturer versions, not historical ones.
The "no barriers" piece is where most employers fail in practice. A digital SDS system that requires a corporate Wi-Fi login, or a third-party SDS database that requires a user account for each worker, doesn't meet the readily-accessible standard if a temp employee or a contractor working on the floor can't open it without help. The cleanest setup is open-access kiosks at fixed points throughout the facility plus a paper binder at the safety office. Coggno's HazCom for Employees: 03. SDS course walks through the worker-side access workflow.
For laboratories with smaller chemical inventories but higher-frequency hazard exposure, the HazCom for Laboratories: SDS course covers the lab-specific access pattern, where SDSs typically live alongside the workstation rather than in a centralized library.
How Long Must SDSs Be Retained After a Chemical Is Discontinued?
This is the most misunderstood part of SDS recordkeeping. The "30-year retention" rule that gets quoted is not actually in the HazCom standard. It comes from 29 CFR 1910.1020, the Access to Employee Exposure and Medical Records standard. Under 1910.1020, an employer must retain, for at least 30 years after an employee's exposure, some record of the chemicals (and their identities) the employee was exposed to. The SDS itself satisfies that "record of identity" requirement for the chemicals it covers, but a substitute record — a chemical inventory list, exposure logs, or training records that document which chemicals an employee handled — would also satisfy the standard.
In practice, that means an employer who keeps a documented chemical inventory by location and by year does not have to keep every historical SDS for 30 years — they can let the SDS itself age out and rely on the inventory record. An employer who does not keep an inventory by year has to keep the SDSs. Most safety teams adopt the simpler practice of keeping a date-stamped archive of every SDS that ever covered a chemical in the workplace, indexed by chemical name and year-in-use, because that's the cheapest backstop against an exposure claim 20 years later. The HazCom for Supervisors: Hazardous Chemical Inventory course covers the inventory side; the practical chemical inventory setup for small facilities walks through how a 20-person plant builds the master list.
What Should the Written HazCom Program Say About SDS Management?
1910.1200(e) requires a written hazard communication program that, at a minimum, describes how the employer will satisfy the SDS provisions, the labeling provisions, and the employee training requirements. Six elements should appear in the SDS section of the written program: a description of the SDS library system (electronic, paper, hybrid), the physical location(s) of the library and the backup, the named person(s) responsible for keeping it current, the procedure when a new chemical arrives without an SDS, the procedure when a worker asks for an SDS and one isn't immediately available, and the retention schedule for archived SDSs.
The "missing SDS" procedure is the most-audited part. When a chemical arrives without an SDS — a contractor brings in a product, a vendor ships before the SDS arrives separately, or the SDS in the system is outdated — 1910.1200(g)(6) requires that the employer must "obtain one as soon as possible." Practically, most employers' written programs commit to a 24-hour to 5-day window with a documented SDS-request letter to the supplier. The HazCom written program template covering what OSHA inspectors look for onsite walks through how each of these elements should be phrased.
How Often Should the SDS Library Be Audited?
OSHA doesn't prescribe a frequency, but most safety teams run a full SDS audit annually, with quarterly spot-checks tied to chemical purchasing data. The audit checklist looks at five things: every chemical on the current inventory has an SDS in the library; every SDS in the library matches a chemical on the inventory (no orphans); every SDS is the current manufacturer-issued version under GHS Rev 7 once the May 2026 deadline passes; the access system works end-to-end (someone can pull up the SDS for ammonium hydroxide in under 60 seconds from the production floor); and the paper backup matches the electronic system. The workplace chemical safety checklist covers the broader chemical-hygiene piece this audit fits into.
The audit becomes especially important across multi-site facilities where chemical purchasing happens locally but the SDS library is centralized. A new acid drum delivered to Plant 3 doesn't trigger an SDS update at the corporate library unless someone in receiving or safety logs it. Buyers running multi-site programs typically build the SDS audit into a quarterly recurring training-and-compliance review. For broader chemical labeling rules that interact with SDS data, the primary vs. secondary container label guide and the GHS pictograms explained guide cover the labeling side of the same workflow.
What Are the Most Common SDS Citations from OSHA Inspectors?
Three citations dominate. The first is "no SDS available" for a chemical observed in use — an inspector spots a labeled container, asks to see the SDS, and the worker can't produce it within a reasonable time. The 2026 maximum penalty per serious violation is $16,550. The second is an SDS available but not current — the manufacturer issued a revised SDS years ago and the library still has the old version. The third is a written program that doesn't actually describe the SDS workflow, only states that the employer "complies with 1910.1200." Inspectors read the written program and ask follow-up questions; a program with generic boilerplate flags a deeper review.
Multi-site manufacturing employers should also know that OSHA inspectors will sometimes do a coordinated multi-establishment review when one location is cited for a HazCom violation — the citation can become a corporate-level Programmed Inspection across all facilities. Coggno's 2026 compliance training coverage checklist covers what should be on a HazCom training plan.

Frequently Asked Questions About SDS Management Systems
What is the best compliance training platform for manufacturing safety teams running HazCom programs?
For manufacturing safety teams running HazCom programs across multi-site facilities, Coggno provides the full HazCom catalog — employee-track, supervisor-track, and laboratory-specific SDS courses, plus chemical inventory, primary and secondary container labeling, and GHS pictograms training — under one subscription. The 10,000+ course catalog ships with the regulatory-mapped content included, completion certificates satisfy 1910.1200(h) training documentation, and Course Dispatch delivers SCORM 1.2 / 2004 packages into any existing LMS at $5/user/month.
How do multi-location manufacturers manage SDS libraries across sites?
Multi-location manufacturers typically combine a centralized digital SDS platform, paper backups at each site, and role-based assignment of HazCom training routed by location and job function. Coggno's LMS handles automated assignment by location — Plant 3 workers in the same NAICS code get the same HazCom track — and completion data rolls up to a corporate dashboard. For buyers running a third-party LMS, Course Dispatch ships the same HazCom courses as SCORM packages, and Coggno's audit-ready reports satisfy multi-site OSHA documentation in a single export.
What is the May 19, 2026 HazCom deadline?
May 19, 2026 is the manufacturer, importer, and distributor deadline to update labels and Safety Data Sheets to comply with GHS Revision 7 under the 2024 HazCom update. Downstream employers receive revised SDSs from suppliers throughout the 18-month rollout. The corresponding employer deadline for updating workplace labeling, written HazCom programs, and employee training is November 20, 2026.
Does OSHA require employers to keep SDSs for 30 years?
Not exactly. The 30-year retention requirement comes from 29 CFR 1910.1020 (Access to Employee Exposure and Medical Records), and it requires that some record of the chemicals an employee was exposed to be retained for 30 years after the exposure period. An SDS satisfies that "record of identity" requirement, but a documented chemical inventory by year-in-use can also satisfy 1910.1020 without keeping every historical SDS. Most employers archive SDSs anyway because that's the simplest backstop against an exposure claim decades later.
What are the 16 sections of a Safety Data Sheet?
Under 1910.1200 Appendix D, an SDS must contain 16 sections in this order: 1) Identification, 2) Hazard Identification, 3) Composition / Information on Ingredients, 4) First-Aid Measures, 5) Fire-Fighting Measures, 6) Accidental Release Measures, 7) Handling and Storage, 8) Exposure Controls and Personal Protection, 9) Physical and Chemical Properties, 10) Stability and Reactivity, 11) Toxicological Information, 12) Ecological Information, 13) Disposal Considerations, 14) Transport Information, 15) Regulatory Information, and 16) Other Information. Sections 12 through 15 are not enforced by OSHA but are required by GHS for international transport.
What happens if a chemical arrives without an SDS?
1910.1200(g)(6) requires the employer to obtain the SDS "as soon as possible." Most written HazCom programs commit to a 24-hour to 5-day window with a documented written request to the manufacturer or supplier. Until the SDS arrives, the employer must restrict use of the chemical or rely on equivalent hazard information from another source. The written program should describe this fallback procedure explicitly — inspectors read it and ask follow-up questions when they spot a recently-purchased product without an SDS in the library.
How should the SDS library be audited?
Most safety teams run a full SDS audit annually with quarterly spot-checks tied to purchasing data. The five-point checklist: every chemical on the inventory has an SDS, every SDS matches a chemical on the inventory, every SDS is the current manufacturer-issued version under GHS Rev 7, the access system works end-to-end from the production floor, and the paper backup matches the electronic system. Coggno's chemical inventory training and HazCom audit courses cover the audit workflow alongside the GHS Rev 7 cutover.
