Safety data sheets provide information on chemical products that help users of those chemicals to make a risk assessment. They describe the hazards the chemical presents, and give information on handling, storage and emergency measures in case of accident.
Safety data sheet information may lead to guidance appropriate for your task. COSHH essentials is a web tool that advises employers on good control practice.
A safety data sheet is not a risk assessment. You should use the information it contains to help make your own assessment.
As well as receiving chemicals you may supply them to others. If you do, you must pass on information (as safety data sheets) to those whom you supply.
