What are Safety Data Sheets (SDS)?

Safety Data Sheets (SDS) are used to communicate the dangerous properties of chemical substances and mixtures and the measures that must be taken to control the risk associated with them.

Safety data sheets include detailed instructions on how to use the substance. The main objective is to ensure safe use. They also include information about the product: physical-chemical data, toxicity, effects on health, first aid, chemical reactivity, storage, necessary provisions and protection and all the safety protocols to use hazardous products.

They also include all the human health and environmental risks.
