Final answer:
The Occupational Safety and Health Administration (OSHA) regulates the level of exposure employees may have to hazardous materials in quick-serve restaurant supply businesses, enforcing safety standards such as informing employees of hazards and providing safety equipment.
Step-by-step explanation:
The extent to which quick-serve restaurant supply businesses can expose their employees to hazardous materials is regulated by the Occupational Safety and Health Administration (OSHA). OSHA sets standards to ensure the health and safety of workers, including the regulation of exposure to hazardous chemicals and enforcement of safe work practices. Under OSHA's authority, employers are required to minimize risks, inform employees about potential hazards, and provide necessary protective equipment. Additionally, employers must abide by the General Duty Clause of the OSH Act to maintain a workplace free from recognized serious hazards. In the case of hazardous materials, regulations from the United States Department of Transportation and the Environmental Protection Agency may also apply.
