What type of sheet is used to relay chemical hazard information from the manufacturer to the employer?

The correct choice is the Safety Data Sheet (SDS). This document is crucial in workplace safety and health regulations, particularly under OSHA's Hazard Communication Standard. It serves to relay comprehensive information about chemical hazards, including their properties, health effects, and necessary safety precautions for handling and using those substances.

Each Safety Data Sheet is designed to help employers and employees identify risks associated with chemicals and implement appropriate safety measures. It comprises various sections detailing aspects such as first-aid measures, exposure controls, personal protective equipment, and disposal considerations.

In contrast, the other options do not fulfill the same role as the SDS. A chemical report may discuss various substances or studies but lacks the standardized structure and detailed safety information. A hazardous material sheet, while potentially including information about chemical hazards, does not have the same recognition or regulation as an SDS and may not conform to the same comprehensive format. A compliance document might relate to adherence to regulations but would not specifically provide information about chemical hazards. The SDS is the standard document recognized for this purpose.
