The IIAR Ammonia Refrigeration Piping Handbook is a guidance document and is not included in IIAR’s suite of mandatory ANSI standards, using informative language such as “may, should, it is recommended”. Nevertheless, its recommendations are critical for safety and risk management; inadequate pipe supports, for example, could lead to an ammonia release in the event of an earthquake, prolonged vibration, or physical impact, making the design considerations in the handbook essential for preventing catastrophic failures. The handbook's guidance is often cited as a recognized and generally accepted good engineering practice (RAGAGEP) by regulatory bodies such as the EPA and OSHA.
