Various national and international regulations govern the disclosure of toxicology information. For instance, the Globally Harmonized System (GHS) provides a standardized method for classifying and labeling chemicals, facilitating consistent communication of hazards. In the United States, the Toxic Substances Control Act (TSCA) mandates the reporting and record-keeping of chemical substances, while the REACH regulation in the European Union requires companies to register and provide safety data for chemicals produced or imported in significant quantities.
