HazCom by the numbers: What’s new and what’s next
Attendees at last week’s Society for Chemical Hazard Communication conference in Washington DC got a peek at OSHA’s preliminary enforcement data from fiscal year (FY) 2025, as well as glimpses into what’s next for the Hazard Communication (HazCom) standard. Guest speakers Janet Carter, Senior Health Scientist at OSHA, and Jennifer Kim, Director, Office of Health Enforcement at OSHA, shared their insights.
HazCom #2 on OSHA’s Top 10 list
Although the HazCom standard has been around for decades, it continues to be a challenge for employers. Preliminary enforcement data for FY 2025 show it ranked second on OSHA’s Top 10 list of most frequently cited standards, with:
- 1,737 inspections
- 3,107 citations issued
- $4,838,954 in total penalties
The most frequently cited paragraphs were:
- Written program, 1910.1200(e)(1)
- Training, 1910.1200(h)(1)
- Maintenance of safety data sheets (SDSs) and employee accessibility, 1910.1200(g)(8)
- Develop, obtain, and/or maintain SDSs, 1910.1200(g)(1)
- Workplace labeling, 1910.1200(f)(6)(ii)
Regulatory and resource updates
In May 2024, OSHA updated the HazCom standard to align with Revision 7 of the GHS, or Globally Harmonized System of Classification and Labeling of Chemicals. The revisions took effect July 19, 2024, with staggered compliance dates for chemical manufacturers, importers, and distributors evaluating mixtures and substances, and for employers impacted by any changes to these evaluations. OSHA issued technical revisions and edits to the standard in October 2024, and Carter said a second set of “minor editorial corrections” are anticipated later this year.
Also in the works are updates to FAQs, CPL 02-02-079 (OSHA’s HazCom directive for inspectors), and other publications related to the revised HazCom standard. No date was given on the CPL, although it was said to be “in the final stages.” Persons interested in updates should keep an eye on the agency’s Hazard Communication topic page at osha.gov. Kim also noted that the popular “red-line strikeout” version of 29 CFR 1910.1200, which shows exactly what changed with the May 2024 revision, will return to the agency’s website “soon.”
Upcoming compliance dates
As mentioned, the revised HazCom standard took effect July 19, 2024, with staggered compliance dates starting January 19, 2026.
| 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 (in-house) 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 substances |
| January 19, 2028 | For mixtures, as necessary: •Update any alternative workplace (in-house) labeling, •Update HazCom training program, and •Provide additional employee training for newly identified physical, health, or other hazards covered | Employers |
* Mixture means a combination or a solution composed of two or more substances in which they do not react.
Key to remember: OSHA’s Hazard Communication standard continues to challenge employers, reaching #2 on the agency’s Top 10 list for FY 2025. OSHA officials anticipate minor editorial corrections to the standard later this year and are updating guidance documents impacted by last year's revisions.
