For mixtures, what additional information is listed in SDS Section 3?

• A. The Chemical Name and Concentration or Concentration Ranges of All Ingredients Which Are Classified as Health Hazards
• B. The Regulatory Classifications Only
• C. The pH and Flash Point of the Mixture
• D. The Storage Conditions

Answer: (A)

The key idea is that Section 3 shows what makes up the product in terms of its ingredients. For mixtures, this part lists the chemical name and the concentration, or concentration range, of every ingredient that is classified as a health hazard or that contributes to the hazards of the mixture. Knowing exactly which components are hazardous and in what amounts helps you assess risks, choose appropriate controls, plan safe handling, and respond to an exposure or spill. If a hazardous ingredient is considered a trade secret, the exact identity may be withheld, but the concentration range and the fact that it contributes to the hazard still need to be disclosed. The other items listed don’t belong in Section 3: pH and flash point are physical properties found in other sections, storage conditions belong in the section on handling and storage, and regulatory classifications are addressed elsewhere in the SDS.
