Since the first edition in 1948, Patty's Industrial Hygiene and Toxicology has become a flagship publication for Wiley. In the course of its nearly six decades in print, it has evolved into a standard reference for the fields of occupational health and toxicology. The volumes on Industrial Hygiene are cornerstone reference works for chemists, engineers, toxicologists, and occupational safety personnel. Volume 2 covers Hazard Control: Engineering, Administrative and Personal Protection. Along with the updated and revised chapters from the prior edition, this volume has two new chapters: Administrative Controls and Personal Protective Equipment.
