A practical tool that helps you to master the code you deal with every day!This comprehensive publication provides a convenient reference for regulations in the 2015 International Fuel Gas Code® (IFGC®). Presented in an easy-to-reference format the commentary includes the full text of the code, including tables and figures, followed by corresponding commentary at the end of each section in one document. Every chapter begins with “General Comments” and “Purpose” sections followed by code and commentary to subsequent sections, tables and figures. This in-depth publication focuses on providing the full meaning and implications of the 2015 IFGC®. The commentaries are designed to suggest the most effective method of application, and the consequences of not adhering to the code. This is an excellent reference for code officials, engineers, architects, inspectors, plans examiners, contractors and anyone who needs a better understanding of the 2015 IFGC®.
