A Safety Data Sheet (SDS), previously called a Material Safety Data Sheet (MSDS), is a document that provides information on the properties of hazardous chemicals and how they affect health and safety in the workplace. For example an SDS includes information on:

• the identity of the chemical, 

• health and physicochemical hazards, 

• safe handling and storage procedures, 

• emergency procedures, and 

• disposal considerations. 

The SDS should always be referred to when assessing risks in the workplace.
