Ammonia is renowned for its favorable thermodynamic properties. This guidance may go further than the minimum needed to comply with the law. Refrigerant grade anhydrous ammonia is a clear, colorless gas or liquid and about 99.95% pure. SCOPE 2.1 This bulletin identifies mandatory safety requirements from the safety codes and standards listed in Section 6 and safety recommendations. <> This provides essential over-pressure protection, as cold liquid ammonia when isolated will expand as it warms up and exert pressures that could rupture the pump or piping unless relieved. At the same time, a motorist traveling on the highway entered the cloud of ammonia and subsequently lost her life. When it is mixed with even a trace amount of water, it will attack copper, zinc, tin, cadmium and most of their alloys. In areas where there is machinery with components that contain Ammonia, always ensure there is adequate ventilation. <> When working in the industrial ammonia refrigeration field, it’s vital employees know potential safety hazards and proper safety procedures in the event an accident occurs. Our employees are provided with safety glasses, fall arrest equipment, ear protection, feet protection, high voltage electrical gloves, gloves, lockout tags and locks. endstream <>/ExtGState<>/XObject<>/ProcSet[/PDF/Text/ImageB/ImageC/ImageI] >>/MediaBox[ 0 0 595.32 841.92] /Contents 4 0 R/Group<>/Tabs/S/StructParents 0>> 13 0 obj Course with 3-Night Hotel Stay Course Only * RAGAGEP/Operator III. Additionally, in systems designed to be oil-free, internal corrosion may occur. See EPA’s About PDF page to learn more. anhydrous ammonia. We also have a professional Human Resource management staff to assist … 10 0 obj Celsius, but in situations where hot gas defrosts lines and in conditions where dampness and heat are together, corrosion can happen very quickly. Specifies criteria for materials, design parameters, marking and testing of valves and strainers used in closed circuit ammonia refrigeration systems. Industrial Ammonia Refrigeration systems have components such as compressors, piping and vessels which are designed to contain ammonia at the correct pressure. In industry, ammonia is used in petroleum refining, to manufacture pharmaceuticals, to disinfect water, and as a refrigerant. Chemical treatments for this are available and the advice of suppliers should be rigorously respected. Ammonia Refrigeration Process Safety – Online Click Here To Register Today.

This course will teach you how to utilize ammonia refrigeration while ensuring safety and preventing future risks. Correct it: Per process safety management (PSM), ensure personnel involved with the operation and maintenance of the ammonia system receive initial training and … <> Ammonia is a commonly used chemical in commercial and household cleaners. Ammonia Refrigeration Pumps Safety Recommendations First and foremost, we advise having a pressure relief device in any part of an ammonia pump and piping system that can be “valved” off. Ammonia Refrigeration Best Practices – Online Click Here To Register Today. It boils at an atmospheric pressure of -33o Celsius. The cloud produced from the release drifted from the plant, across a highway, and in to a wooded area. Ammonia refrigeration works much like Industrial Refrigeration systems using synthetic refrigerants, with the major exception being that it uses anhydrous ammonia as the refrigerant. Ammonia refrigeration systems that have 10,000 pounds of ammonia (approximately 2,000 gallons) or more are subject to OSHA’s process safety management requirements. If there is a 15% or higher concentration in the air, it can ignite when exposed to an ignition source. <> ANSI/IIAR 3 , American National Standard for Ammonia Refrigeration Valves. A tragic example of this took place in British Columbia in 2017, when a pinhole in an ice rink brine chiller allowed Ammonia and brine to mix. Ammonia refrigeration companies like Industrial Refrigerated Systems Ltd. provide installation, service and parts for various cooling applications and systems. Ammonia is considered a high health hazard because it is corrosive to the skin, eyes, and lungs. Food and beverage safety is a critical matter for plant managers, and when it comes to storing food using ammonia refrigeration systems, ensuring the safety of workers is of utmost importance. Adequate ventilation around an ammonia refrigeration unit is the best defence. The Department of Transportation classifies it as a non-flammable compressed gas. recommended for a safe ammonia refrigeration system for use by qualified individuals making safety inspections. These regulations are ever changing, with nearly every aspect of your business being impacted by … The purity of the anhydrous ammonia is vital to the properties that make it a good refrigerant. Having fire suppression systems in place around ammonia refrigeration units is often recommended. Keeping product at specific temperatures is required for industrial processes as well as preservation of various food items. Understanding how it works, and how to use it safely is critical. Pressure Vessel and Refrigeration Safety Regulation which are enforced by Technical Safety BC ... Owners of ammonia refrigeration plants must comply with the requirements of the Safety . Industrial Ammonia Refrigeration systems have components such as compressors, piping and vessels which are designed to contain ammonia at the correct pressure. Industrial Consultants, LLC is focused on the food industry, due to the large number of refrigeration systems using anhydrous ammonia, for which safety and health regulations are very strict. to properly manage your ammonia refrigeration needs.
