No other volume comes close to the scope of useful data on hazardous substances in this classic orginated by N. Irving Sax. Updated features include 2,000 new entries, along with revisions of all entries retained from the previous edition. Obscure and less commercially important substances have been dropped, and more data is included on physical and reactive properties. Toxic Effect Codes that indicate reported toxic effects are also incorporated. All carcinogenic entries have been reorganized and assigned to low, medium, or high categories for toxic, fire, explosive, or reactivity hazards. Includes the standards and recommentations for OSHA, PEL, ACGIH, TLV and NIOSH REL workplace air levels and NIOSH's Registry of Toxic Effects of Chemical Substances accession number. Three volumes.
