How do employers know if an SDS is current?

OSHA states in 1910.1200(g)(2)(xvi) that Section 16 of the SDS, “Other Information,” should include the “date of preparation or last revision.”

Also, 1910.1200(g)(5) requires that the chemical manufacturer, importer, or employer preparing the SDS must ensure that the information provided accurately reflects the scientific evidence used in making the hazard classification. If the chemical manufacturer, importer, or employer preparing the SDS becomes newly aware of any significant information regarding the hazards of a chemical, or ways to protect against the hazards, this new information must be added to the SDS within three months.
