Which of the following is NOT a part of hazard communication?

The correct choice signifies that listing products in a marketing catalog is not a component of hazard communication. Hazard communication focuses on conveying information regarding the hazards associated with chemicals through proper labeling, safety data sheets, and ensuring that employees receive safety training related to these hazards.

Labeling chemicals properly ensures that anyone handling the substances is aware of their potential dangers and can take appropriate precautions. Safety data sheets are essential for offering detailed information about the chemical's properties, health hazards, protective measures, and safety procedures. Ensuring employee safety training is crucial so that workers understand how to handle hazardous materials safely, recognize hazards, and know what to do in case of an emergency.

In contrast, a marketing catalog's purpose is to promote products and may not include critical safety information mandated by hazard communication regulations. This disconnect highlights why the catalog listing does not contribute to effective hazard communication.
