Which document provides a profile of hazardous substances?

The correct choice, which identifies the document that provides a profile of hazardous substances, is the Material Safety Data Sheet (MSDS). An MSDS is a detailed informational document prepared by the manufacturer or importer of a chemical, and it contains essential safety information regarding the handling, use, storage, and potential hazards of a specific chemical. It includes details such as physical and chemical properties, health hazards, protective measures, and emergency procedures in case of an accident, making it a critical resource for understanding hazardous substances in the workplace or environment.

Other documents listed serve different purposes. For instance, the Hazardous Substances Data Bank (HSDB) provides comprehensive information on toxicology, environmental fate, and human exposure data but is not typically formatted as a profile for individual substances like the MSDS. An OSHA report mainly covers compliance with workplace safety regulations rather than offering detailed profiles of hazardous materials. An Environmental Impact Statement assesses the potential impact of proposed projects on the environment but does not provide specific profiles of hazardous substances. Therefore, the MSDS is the most relevant and focused document for providing a detailed profile of hazardous substances.
