The Occupational Safety and Health Administration (OSHA) recently announced a four-month extension for compliance deadlines related to the 2024 updates of the Hazard Communication Standard (HCS). This extension provides the agency and the regulated community, including manufacturers and employers, additional time to review upcoming guidance materials and ensure a smooth transition to the revised requirements.
Background: The Purpose of the Hazard Communication Standard
Originally established in 1983, the Hazard Communication Standard is designed to ensure chemical safety in the workplace. The standard operates on the principle that employees have both a right and a need to know the identities and hazards of the chemicals they are exposed to while working.
To achieve this, the HCS requires a comprehensive approach to communication:
- Hazard Classification: Identifying and classifying the potential hazards of chemicals.
- Labeling: Ensuring containers are properly labeled with hazard warnings and precautions.
- Safety Data Sheets (SDSs): Maintaining detailed fact sheets that provide information on chemical properties, risks, and safe handling procedures.
- Training: Educating employees on how to interpret labels and SDSs to protect themselves.
Who Is Covered by the Standard?
The HCS is broad in scope and covers all employers with hazardous chemicals in their workplaces. This includes any employer with at least one employee and one hazardous chemical. Specific industries and entities covered by these regulations include:
- General Industry: Most private-sector employers across various sectors.
- Specialized Sectors: Construction, shipyard employment, marine terminals, and longshoring.
- Supply Chain Entities: Chemical manufacturers, importers, and distributors who must classify hazards and provide information to downstream customers.
- Workplace Operations: Healthcare facilities, laboratories, warehousing, and retail operations where employees may be exposed to hazardous substances.
Recent Legislative and Regulatory Updates
In May 2024, OSHA issued a final rule to align the HCS with the seventh revision of the United Nations’ Globally Harmonized System of Classification and Labelling of Chemicals (GHS). These updates introduce new hazard classes, revised labeling for small containers, and updated requirements for Safety Data Sheets (SDS) to improve the quality of information provided to workers.
While the final rule originally set compliance deadlines beginning in January 2026, OSHA has moved these dates back by four months to allow for the publication of necessary technical guidance.
New Compliance Deadlines
The updated schedule follows a tiered approach based on the type of chemical and the role of the organization.
For Substances
- Manufacturers, Importers, and Distributors: Must update labels and SDSs by May 19, 2026.
- Employers: Must update workplace labeling, safety programs, and employee training by November 20, 2026.
For Mixtures
- Manufacturers, Importers, and Distributors: Must update labels and SDSs by November 19, 2027.
- Employers: Must update workplace labeling, safety programs, and employee training by May 19, 2028.
During this transition period, employers and manufacturers may choose to comply with either the 2012 version of the standard, the 2024 version, or a combination of both.
Next Steps for Employers
To ensure compliance with the updated HCS requirements, employers should take the following proactive steps:
- Review Current Procedures: Assess your organization’s current chemical inventory to identify which substances and mixtures will be affected by the new hazard classifications.
- Coordinate with Suppliers: Maintain communication with your chemical suppliers to ensure you receive updated SDSs and labels as they become available.
- Update Written Programs: Revise your organization’s written Hazard Communication Plan to reflect changes in how hazards are identified and communicated.
- Train Employees: Provide training to staff on new pictograms, hazard statements, and the updated SDS format.
- Stay Updated on Developments: Frequently check the OSHA website for the release of new guidance materials that will clarify specific classification and labeling requirements.
- Consult with Experts: Seek advice from safety consultants or legal counsel to navigate the complexities of these updated regulatory requirements.
