MSDS stands for Material Safety Data Sheet. It is a document that provides information about the physical and chemical properties of a hazardous substance or product. The MSDS is intended to help ensure the safety of workers who handle or are exposed to the substance or product, by providing information on the potential health effects, safe handling procedures, and emergency response actions in case of exposure or spill. The information contained in an MSDS typically includes the chemical and physical properties of the substance, such as its melting point, boiling point, and flash point, as well as its potential health hazards, such as toxicity, flammability, and reactivity. The MSDS also provides information on the appropriate protective measures to be taken when handling the substance, such as the use of personal protective equipment (PPE) and safe handling procedures. MSDSs are required by law in many countries, and are an important tool for employers, workers, and emergency responders to understand the hazards associated with a particular substance or product. They are also used in hazard communication programs to inform workers and others about the potential risks associated with a substance or product, and to promote safe handling practices.
