This reference serves the information needs of those who work with hazardous chemicals. Over 5,800 entries are included, about 500 of them new for this edition. Most of the new entries were selected because they are on the EPA TSCA Inventory. Emphasis has been placed on adding and updating physical properties and updating all DOT Classifications. The information presented in the book was extracted from the 11th edition of Dangerous Properties of Industrial Materials. Citation to toxicity data and other less relevant information can be found in that work. Whenever available, physical description, formulas, molecular weights, melting and boiling points, explosion limits, flash points, and the like have been supplied in the entries. The discussion of human exposures includes details on target organs and specific effects reported. Fire and explosion hazards are briefly summarized in terms of conditions of flammable or reactive hazard. Where feasible, firefighting materials and methods are discussed. Each entry concludes with a summary of the hazards presented by the substance. Three cross-indices are provided as appendices to permit rapid location of a material by CAS number, synonym, or DOT guide number. The book will be used by industrial hygienists, environmental safety and fire safety professionals, toxicologists, plant managers, emergency planners, and students. Lewis, a chemist, is former manager of information systems for the National Institute for Occupational Health and Safety. The previous edition of the book was cited in Guide to Reference Books, 11th edition, and in Resources for College Libraries. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
