Safety data sheets (SDS) are technical documents that provide detailed information on the following characteristics of a controlled product:

• Hazards of the product
• Measures to protect workers from those hazards
• Safe handling and emergency measures

SDSs are usually prepared by the manufacturer or supplier of the product. Every product that is classified as a hazardous product under WHMIS that is intended for use, handling or storage in a workplace in Canada must have an SDS.

WHMIS 2015 requires a standard 16-section SDS. All information on the SDS must appear in the specified order. The following table provides SDS headings and specific information under each heading.
