Which standard identifies a hazardous chemical as one that poses a physical or health hazard?

The correct standard that identifies a hazardous chemical as one that poses a physical or health hazard is the Hazard Communication Standard (HazCom). This regulation, established by the Occupational Safety and Health Administration (OSHA), provides criteria for classifying chemicals and ensuring that employees are informed about the hazardous properties of the chemicals they may encounter in the workplace.

Under HazCom, chemical manufacturers and importers are required to evaluate the hazards of the chemicals they produce or import and communicate that information through labels and safety data sheets (SDS). The emphasis on defining and communicating physical and health hazards ensures that workers can take appropriate precautions to protect themselves when working with hazardous substances, thereby promoting a safer workplace environment.

Other relevant standards, such as the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Resource Conservation and Recovery Act (RCRA), and the Toxic Substances Control Act (TSCA), deal with various aspects of hazardous waste management, environmental protection, and chemical safety, but they do not specifically focus on identifying hazardous chemicals in the same way that HazCom does.
