Safety Data Sheets (SDS) are required by the REACH Regulation.
SDS are key documents in the safe supply, handling and use of chemicals. They should help to ensure that those who use chemicals in the workplace do so safely with risk of harm to users or the environment.
A SDS will contain the information necessary to allow employers to do a risk assessment as required by the Control of Substances Hazardous to Health Regulations (COSHH). The SDS itself is not an assessment. However it will describe the hazards helping employers assess the probability of those hazards arising in the workplace.
SDS are a must if a chemical is hazardous and is being supplied for use at work, whether in packages or not. SDS are also needed if your chemical is not classified as hazardous but contains small amounts of a hazardous substance(s).
