9. Lesson 1 Designing and Installing Exterior Vapor Distribution Systems Course Resources and References: Codes Many agencies of the federal government play major roles in developing regulations, codes, and standards to ensure the safe transportation, storage, handling, and use of propane, including:  The American National Standards Institute (ANSI)  The National Fire Protection Association (NFPA)  The U.S. Department of Transportation (DOT)

10. Lesson 1 Designing and Installing Exterior Vapor Distribution Systems Course Resources and References: Codes (cont.) Each of these organizations develops regulations, codes, or standards referenced throughout this course. Here are the two of the most common references used in these lessons:  NFPA 54, National Fuel Gas Code: This publication provides standards for the installation of fuel gas piping systems, appliances, equipment, and related accessories.  Code of Federal Regulations (CFR): This government resource contains all of the federal rules and regulations that apply to the propane industry. This course references various federal regulations, including those developed by the DOT governing the construction of cylinders and the safe transportation of propane. Always check with your supervisor to determine all of the safety codes that apply to your job responsibilities. As a general rule, it is important that you follow the manufacturer’s instructions when installing and using products.

11. Lesson 1 Designing and Installing Exterior Vapor Distribution Systems Course Resources and References: Handbooks The NFPA 54 handbook helps explain new codes within the industry and provide commentary that brings the legalistic language of the code to life. The handbook can be used to help company managers, supervisors, and you apply the new code requirements on the job. The references to NFPA 54 and other codes and standards, are included in this training to:  Increase your awareness of these important resources.  Provide a general overview of how these codes and standards govern your work.  Show you how these codes and standards relate to concepts presented in the training.  Provide background for you to better understand rules and regulations at your place of work.  Familiarize you with code that can be used as resources during your certification test.
