A Materials Safety Data Sheet [MSDS] is a printed form containing data about the properties of a substance. It is intended to provide staff using the product with guidance on handling or working safely with the substance, and includes physical characteristics of the substance such as melting point, boiling point and flash point, as well as toxicity, health effects, first aid procedures in the event of spillage or contact, and advice on storage and disposal. Data Sheets should be accessible to all staff that work with the materials. Many organisations use databases to ensure up-to-date information on all dangerous goods, but in particular to ensure that data sheets are up to date so that staff dealing with the products can understand the risks and adopt the most appropriate protective equipment and safe handling procedures.
