A Material Safety Data Sheet (MSDS), now more commonly referred to as a Safety Data Sheet (SDS), is a document that provides essential information about hazardous substances. The primary purpose of the SDS is to inform users about the properties of these substances, including their potential hazards, safe handling practices, and emergency procedures.

The supplier of the controlled product is responsible for providing the SDS. This requirement is grounded in regulations that mandate suppliers to ensure that their products are accompanied by appropriate safety documentation. This ensures that anyone who handles the material, such as workers and safety personnel, has access to the vital information needed to work safely with the product.

In contrast, while the Occupational Health and Safety Committee, the federal government, and plant supervisors play important roles in promoting workplace safety and compliance with regulations, it is ultimately the supplier's responsibility to supply the SDS. They must create and provide this documentation to inform users of the risks associated with their products and the necessary precautions to take, thereby facilitating safe usage and handling practices in all relevant environments.
