If the chemical material is a mixture, what must the Material Safety Data Sheet (MSDS) identify?

Correct Answer: Option A — The name of each hazardous ingredient.

OSHA Hazard Communication Standard 29 CFR 1910.1200 requires that for mixtures, the SDS must identify each hazardous ingredient that comprises 1% or more of the mixture, or 0.1% for known carcinogens. This ensures personnel are aware of all chemical risks present during handling, storage, or emergency response operations.
