Recently OSHA provided a final rule for how it was going to change its hazard Communication standard 29 CFR 1910.1200 to reflect the global harmonization on chemical hazards (see earlier discussions of this topic in this blog).
The EPA operates under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) and has its own regulations for describing chemical hazards on a safety data sheet. As a first step towards harmonization, on April 20th the EPA will publish a notice of the differences between its requirements for safety data sheets and OSHA's in the Federal Register.
We all know that regulations change at a glacial pace, and while this notice is not actually harmonization, hopefully this is the first small step in the right direction.
