Book excerpt: This revised edition of a best-selling book continues to provide a basis for the identification and evaluation of chemical reaction hazards for chemists, engineers, plant personnel, and students. Before undertaking the design of a chemical manufacturing process it is vital that the chemical reactions involved be fully understood, potential hazards assessed, and safety measures planned. Chemical Reaction Hazards aims to help the people responsible for this design and operation to meet the general duties of safety. Two major additions to this revised book are the appendices. One of these describes 100 incidents, illustrating their cause and indicating consequences if appropriate procedures within this guide are not followed. The second provides a practical example of a typical chemical reaction hazard assessment, from consideration of the process description, through experimental testing to the specification of safety measures.
