This third edition has resulted from a major review of the content of most of the tables, the introduction of a few new tables that were suggested by users, and a decision to introduce hazard codes for inorganic and organic compounds. The text emphasizes the relationship between the structure and chemical properties, and the physical properties of the compound they make up. It includes risk and safety codes which provide details of associated hazards. The integration of data and risk and safety codes offers a personal reference source for material which is otherwise not readily available to students. The recommended methods of handling hazardous chemicals are clearly defined, making the book ideal as a laboratory manual.
