What information is in the Hazardous Ingredients section of an SDS?

• A. The active ingredient and other components of the product.
• B. The pesticide's color and odor.
• C. The recommended storage temperature.
• D. The label's first aid instructions.

Answer: (A)

Hazardous Ingredients identifies the chemicals that drive the hazards of the product. In this section, you’ll find the active ingredient plus any other components that are considered hazardous, listed with their concentrations (or ranges) and often their CAS numbers. This is the part of the SDS that tells you exactly which substances in the product pose risks so you can assess exposure and match appropriate precautions.

Color and odor are physical properties and not the focus of this section. Storage temperature is covered under handling and storage guidance, not the hazardous ingredients list. First aid instructions appear in a different section dedicated to first aid, not in the hazardous ingredients portion.
