MSDS: Material Safety Data Sheets

Are a widely used system for cataloging information on chemicals, chemical compounds, and chemical mixtures. MSDS information may include instructions for the safe use and potential hazards associated with a particular material or product. MSDS can be found anywhere chemicals are being used.

There is also a duty to properly label substances on the basis of physico-chemical, health and/or environmental risk. Labels include hazard symbols such as the Saint Andrew's Cross (a black diagonal cross on an orange background which is used in the European Union to denote a harmful or irritant substance).
