2021 International Fuel Gas Code The 2021 IFC® contains regulations to safeguard life and property from fires and explosion hazards. Topics include general precautions, emergency planning and preparedness, fire department access and water supplies, automatic sprinkler systems, fire alarm systems, special hazards, and the storage and use of hazardous materials. Key changes to the IFC include: Requirements for Additive Manufacturing (3-D Printing) equipment and operations for both non-industrial and industrial applications are now provided. Flame propagation performance of permanently installed artificial combustible vegetation is required to be verified when exceeding certain heights located on roofs or in close proximity to buildings. Provisions for emergency responder communication were revised to reflect the expansion of such systems beyond radios and the need for increased performance of such systems. Sprinkler requirements for the storage, manufacture and sale of upholstered furniture and mattresses were updated and clarified. Part of this update is a new exception for single-story self-storage facilities accessed directly from the exterior. An automatic sprinkler system is now required for open parking garages exceeding a certain fire area threshold. The requirements for energy storage system (ESS) were further refined to reflect the variety of new technologies and applications (in building and standalone) and the need for proper commissioning and decommissioning of such systems. A new chapter was added that provides clarification and specific requirements for the storage of distilled spirits and wines in barrels and casks. The provisions for construction fire safety were reorganized and expanded with an emphasis on the owner’s responsibilities. The new language requires a site safety plan and designation of a site safety director. This book is offered in a Loose Leaf OR Softbound format. You can purchase it new or professionally Highlighted & Tabbed for your exam. Why Most Highlighted & Tabbed Books Fall Short? Many contractor exam prep schools sell highlighted and tabbed books. Only one created the system—and perfected it through real-world use. That system was created by Rob Estell, a licensed contractor, President, and Founder. Open-book contractor exams don’t test how much you know. They test how quickly you can locate the correct answer inside dense reference manuals. Rob learned this firsthand by taking exams himself and later confirmed it through years of feedback from thousands of exam candidates. While other schools offer highlighted and tabbed books, most: Use minimal or generic highlights Rely heavily on the existing Table of Contents and Index Miss exam-tested material that isn’t clearly referenced Provide tabs that point to broad sections, not precise answers The result? Students still waste time searching. Rob decided that “good enough” wasn’t good enough. Why The Exam Pros ORIGINAL, detailed-driven highlighted and tabbed books? Thousands of contractors have passed their exams using Rob Estell’s highlighted and tabbed books because they solve the real problem: Knowing the answer But not being able to find it fast enough Built from Contractor Experience & Student Feedback Rob Estell’s system is built using: His own experience as a licensed contractor Personal exam feedback from real testing environments Thousands of data points from exam students nationwide A Proven, Detail-Oriented Navigation System Each book follows Rob’s proven 3-step method: Table of Contents – Identify the general section Precision Tabs – Jump directly to the exact topic Strategic, Detailed Highlights – Land on the answer instantly Our highlights are thorough and detail-oriented, guiding your eye exactly where exam answers are located—not just coloring pages for appearance. Every highlight is intentional. Every tab exists because the book failed to guide the reader quickly enough. If a topic cannot be found efficiently through the Table of Contents or Index, it gets a custom tab and targeted highlight. These books are designed to help you outperform the clock, not just prepare!
