A Safety data sheet (SDS) is the document used by suppliers to communicate essential information down through the supply chain thereby promoting the safe use of their chemical substances and mixtures.
SDSs contain information about the properties of the chemical-based product (substance or mixture), its hazards and instructions for safe handling, disposal and transport as well as first-aid, fire-fighting and exposure control measures. This information can be found in the main body of the safety data sheet (or in the case of substances within the EU in the annexed exposure scenarios).
Within the EU, the requirements for the compilation of the safety data sheets are specified in Annex II of the REACH regulation.
A supplier of a chemical product MUST provide a safety data sheet to a customer if:
Under certain conditions, described in Article 31(3) of the REACH regulation, some mixtures, which do not meet the criteria for classification as dangerous or hazardous, also require a safety data sheet.
Certain situations require the update and re-issue of the safety data sheet:
When any of the above three situations apply, suppliers must provide updated safety data sheets to all former recipients supplied within the past 12 months.
