A Material Safety Data Sheet (MSDS) is a document that provides essential information about a specific chemical or substance. It includes details such as the chemical's properties, potential hazards, safe handling practices, and emergency response measures. MSDSs are crucial for ensuring workplace safety and compliance with regulations. MSDSs are typically required by regulatory agencies like the Occupational Safety and Health Administration (OSHA) in the United States. They help employers and employees understand the risks associated with chemicals and how to use them safely. Each MSDS is specific to a particular substance and is an important resource for anyone working with hazardous materials.
