When is a chemical manufacturer required to distribute Material Safety Data Sheets (MSDSs)?
Hazard information must be transmitted on Material Safety Data Sheets (MSDSs) that must be distributed to the customer at the time of first shipment of the product. The Hazard Communication Standard also requires that MSDSs be updated by the chemical manufacturer or importer within three months of learning of “new or significant information” regarding the chemical’s hazard potential.
