The MSDS is prepared by whom?

The MSDS is prepared by whom?

• A. The product's distributor
• B. The product's manufacturer or importer
• C. The local health department
• D. The end user

Answer: (B)

The main idea is that the hazard information for a chemical is created by the source that develops the product—the manufacturer or importer. They have access to the full data on what the chemical is, what hazards it poses, and how to handle, store, use, and dispose of it safely. Because these details come from the product’s own formulation and testing, the supplier is responsible for preparing the MSDS (or SDS) and for providing it to downstream users, as required by regulations. Distributors may pass along the SDS they received, but they don’t generate the primary safety data. Local health departments don’t create product-specific MSDSs, and end users rely on the MSDS supplied by the manufacturer or importer.
