The International Fuel Gas Code, 2018 Edition by the International Code Council (ICC) establishes uniform regulations for the design, installation, and inspection of fuel gas systems used in residential, commercial, and industrial structures. This code serves as a key reference for contractors, inspectors, and engineers preparing for state licensing and certification exams, particularly those aligned with 1 Exam Prep study programs. The 2018 edition covers essential topics such as gas piping materials, combustion air requirements, appliance installation, and venting standards. The pre-printed tabs available through 1 Exam Prep are designed to assist test-takers in efficiently navigating the IFGC text during open-book examinations for contractor, mechanical, and gas line certification licensing exams under the authority of building departments and boards such as the CILB and ICC.
