What information must be included in an MSDS?

The correct choice is focused on the necessity for the Material Safety Data Sheet (MSDS) to include an identification of the material. An MSDS is a crucial document that provides detailed information about a specific substance, including its properties, handling, storage, exposure controls, and emergency measures. Identifying the material is fundamental because it allows users and emergency responders to recognize what they are dealing with, including any potential hazards it may present.

This identification typically includes the chemical name, synonyms, CAS number, and the recommended uses of the substance. By clearly identifying the material, the MSDS helps ensure the safety of personnel who may come into contact with it, and facilitates proper handling and response to emergencies. Therefore, the inclusion of material identification in an MSDS is essential for compliance with safety regulations and for promoting a safe working environment.
