Decoding the GHS Label
The GHS label is the primary vehicle for communicating chemical hazards to the workforce. With the 2024/2026 update to the Hazard Communication Standard, OSHA has aligned with GHS Revision 7, refining the requirements for these critical labels. While the visual core—the pictogram and the red diamond—remains, the regulatory details regarding small containers and updated hazard statements are essential for compliance.
The Six Mandatory Elements
Every hazardous chemical container must display these six elements:
1. Product Identifier: The name or code matching the SDS.
2. Signal Word: "Danger" (severe) or "Warning" (less severe). Only one appears.
3. Hazard Statements: Standardized phrases describing the hazard (e.g., "Extremely flammable aerosol"). Rev 7 updates these for specific classes like desensitized explosives.
4. Pictograms: The symbol inside a red diamond frame.
5. Precautionary Statements: Measures for safe handling, storage, and disposal. The 2026 update includes revised medical response instructions.
6. Supplier Identification: Name, address, and phone number. New Rule: Must be a U.S. address.
The 2026 Small Container Exemptions
The new rule introduces explicit labeling relief for small containers, a major win for construction sites handling kits and testers.
1. The 100ml Rule
For containers ≤ 100ml: If full labeling is infeasible, the immediate container may omit hazard and precautionary statements.
2. The 3ml Rule (Very Small Containers)
For containers ≤ 3ml:
