It includes general information about the chemical, identification, hazards, composition, safe handling practices, and emergency control measures along with safety precautions for handling, storing and transporting the chemical. Safety Data Sheets must be readily accessible to employees for all hazardous chemicals in their workplace.

The Safety Data Sheet must provide information that identifies the product, its recommended use and the restriction on use that have been imposed. The full name, address and contact details of the supplier must also be given. Hazard identification details must include the hazard class of the substance, any hazard symbols used and a hazard statement.

First Aid measures to be undertaken in the case an emergency must be spelled out on the Safety Data Sheet. This will include the measures to be taken in the case of inhalation, skin contact, eye contact and ingestion. The physical and chemical properties of the substance must also be clearly listed. The complete toxic health effects of the product should also be given.

If the supplier becomes aware of any significant new data, then they should immediately update the Safety Data Sheet accordingly.
