Safety Standards for Ammonia Refrigeration (PDF) (2 pp, 157 K) 8 0 obj <>>> Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air. stream 2. Similarly, sources of heat and flame, including welding activity, should be kept well away from a refrigeration system. When mixed with some organics, it can cause chemical and frost burns. In ammonia refrigeration, the ammonia is often mixed with lubricating oils, which can cause it to become even more flammable. Ammonia refrigeration companies like Industrial Refrigerated Systems Ltd. provide installation, service and parts for various cooling applications and systems. Industrial Ammonia Refrigeration systems have components such as compressors, piping and vessels which are designed to contain ammonia at the correct pressure. Under the Health and Safety at Work Act PCBUs with ammonia-based refrigeration systems at their workplaces have a duty to ensure, so far as is reasonably practicable, that the health and safety of their workers, and others (e.g. endobj It is extremely hard to ignite and is therefore very stable. <> As previously discussed, the Fernie Memorial Arena accident was caused by a pinhole leak which developed due to corrosion. With over 150 years of experience in a range of disciplines, we have the history and certifications to properly manage your ammonia refrigeration needs. Safe Management of Ammonia Refrigeration Systems –May 2017 in Grantham Slide 16 10. When managed properly, ammonia can provide a safe and efficient means of refrigeration. SCS can review the equipment installation against the ANSI/IIAR Standard 2 American National Standard for Safe Design of Closed-Circuit Ammonia Refrigeration … Corrosion occurs slowly on lines permanently below 0o Celsius, but in situations where hot gas defrosts lines and in conditions where dampness and heat are together, corrosion can happen very quickly.
