Eurochem Database involves classification and labelling data in accordance Directive 67/548/EEC and 1999/45/EC and a communication of that hazard via the label. Classification and labelling is therefore a useful tool for risk mangement of chemicals. All marketed substances and preparations must be classified and labelled, irrespective of the quantity placed on the market. The labelling is the first and often the only information on the hazards of a chemical that reaches the user, which could be a consumer or a worker.
