Final answer:
OSHA requires Material Safety Data Sheets to inform workers about chemical hazards and safe handling practices.
Step-by-step explanation:
The organization that requires Material Safety Data Sheets is the Occupational Safety and Health Administration (OSHA).
OSHA mandates these data sheets to ensure workers are aware of the proper handling, potential hazards, and safe disposal methods for chemicals in the workplace.
Material Safety Data Sheets contain crucial information about chemicals, their health risks, safety precautions, and environmental impacts, thereby protecting both employees and the environment.
