Which information is listed in SDS Section 3 for substances?

• A. Chemical Name; Common Name and Synonyms; CAS Number and Other Unique Identifiers; Impurities and Stabilizing Additives Which Contribute to the Classification of the Substance
• B. Chemical Name and Concentration of Ingredients
• C. Handling and Storage Precautions
• D. Personal Protective Equipment Requirements

Answer: (A)

Section 3 covers composition/information on ingredients. It lists the exact identity of the chemical, including the chemical name, any common names or synonyms, and identifiers such as the CAS number and other unique IDs. It also includes impurities and stabilizing additives that influence how the substance is classified hazard-wise. This makes it possible to accurately identify the substance and understand its classification and hazards. The other items point to different sections—handling and storage precautions are in Section 7, and personal protective equipment requirements are in Section 8—so they don’t belong in Section 3. The listed items in Section 3 are best captured by including the chemical identity, synonyms, identifiers, and any impurities or stabilizers that affect classification.
