Providing an MSDS/SDS and label for a UW Synthesized Chemical

Departments and supervisors must, if synthesizing a hazardous chemical and providing it to other labs outside the UW system, or if transporting a synthesized chemical over public streets, generate the Material Safety Data Sheet (MSDS) and generate a label. If providing it to agencies in countries which enforce the Globally Harmonized System of Classification and Labeling of Chemical Substances (GHS), the department and supervisor providing the chemical must generate a Safety Data Sheet (SDS) and label in accordance with that system before shipping or transporting the chemical.

Washington Administrative Code (WAC) 296-839 and WAC 296-828 require that if you provide chemicals to agencies outside your employer's units, the organization producing a hazardous chemical needs to identify any known hazards of the chemical, label the chemical container, and provide required information to the receiving lab in the form of an MSDS (or SDS). There is no de minimus quantity exemption even if the chemical will only be used as a research chemical by the recipient. Although some scientific data may not be available, the person producing the chemical still has the most relevant information about the chemical and its hazards, and that information needs to be formally passed along to the recipient.
