Safe Management of Ammonia Refrigeration Systems –May 2017 in Grantham Slide 16 10. However, because it is so toxic to humans, the maximum allowable exposure level of Ammonia for an eight-hour work day is 50 parts per million (ppm). Care must be taken to reduce corrosion, especially in wet and damp conditions and when metal temperatures are below the dew point. In a wide range of applications, it outperforms synthetic refrigerants. We also have a professional Human Resource management staff to assist … Ammonia (NH3) is a well-known refrigerant, particularly applicable in large, industrial plants where its advantages can be fully utilized without compromising safety. Ammonia Safety. 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. Your business’s WHMIS information should include information on Ammonia and industrial ammonia refrigeration systems. Adequate ventilation around an ammonia refrigeration unit is the best defence. Emergency response - AEGLs AEGL-1 is the airborne concentration, expressed as parts per million or milligrams per cubic meter (ppm or mg/m3) of a substance above which it is predicted that the general population, including susceptible individuals, In areas where there is machinery with components that contain Ammonia, always ensure there is adequate ventilation. Corrosion on external surfaces of steel piping and vessels used for refrigeration systems can reduce the effectiveness of containment – and eventually leaks may occur. Should parts of the system such as pipes, joints or valves need to be removed, a properly qualified person will need to ensure the relevant parts of the cooling systems have been depressurized and purged of Ammonia. Ammonia refrigeration companies like Industrial Refrigerated Systems Ltd. provide, for various cooling applications and systems. Ammonia is renowned for its favorable thermodynamic properties. There is a risk of liquid Ammonia expanding and rupturing components of the system and escaping into the air. Belonging to a group of "natural" refrigerants, ammonia is also favored because of its environmental friendliness. Additionally, in systems designed to be oil-free, internal corrosion may occur. •Ammonia is flammable in air at concentrations of 15% to 28% by volume, requiring a temperature of 450 - 500ºC •Auto-ignition will occur above 630ºC. To allow it to work effectively and safely, companies like Industrial Refrigerated Systems can provide you with advice, installation, service and parts. 7. How to Reduce the Risk of Asbestos Exposure in the Workplace, Ammonia Refrigeration Guidelines for Scheduled Inspections, Ammonia Industrial Refrigeration System Start-Up Procedures, Common Hazards of Industrial Ammonia Refrigeration. 6 0 obj But precautionary measures and safety systems are crucial as ammonia is a toxic substance that can be extremely hazardous: Ammonia is an irritant that is corrosive to the skin, eyes, respiratory tract and mucous membranes. In fact, ammonia is often sprayed on fields as a fertilizer in industrial farming. Celsius, but in situations where hot gas defrosts lines and in conditions where dampness and heat are together, corrosion can happen very quickly. anhydrous ammonia. Clean ammonia unit when needed and contact a water treatment company if water contamination is detected. Improve Workplace Safety with Ammonia Refrigeration System Inspections. Ammonia Refrigeration Best Practices – Online Click Here To Register Today. Resource Compliance Online Process Safety Training - Ammonia Safety & Identification SCOPE 2.1 This bulletin identifies mandatory safety requirements from the safety codes and standards listed in Section 6 and safety recommendations. Refrigerant grade anhydrous ammonia is a clear, colorless gas or liquid and about 99.95% pure. As Ammonia gas is lighter than air, it will rise and can easily and effectively be dispersed from the area via an effective ventilation system. Ammonia, however, is not without hazards. endobj 7 0 obj With its combination of gases, solutions, piping and compressors, an industrial refrigeration system is complex. This document describes key safety measures that should be in place at any ammonia refrigeration facility. In agriculture, ammonia can be used for crop processing, fertilizers, or as an anti-fungal treatment for citrus. Understanding how it works, and how to use it safely is critical. It boils at an atmospheric pressure of -33. refrigeration system contains Ammonia in both liquid and gas forms. In industry, ammonia is used in petroleum refining, to manufacture pharmaceuticals, to disinfect water, and as a refrigerant. When it is mixed with even a trace amount of water, it will attack copper, zinc, tin, cadmium and most of their alloys. It includes inspection data Workplaces with ammonia-based refrigeration systems must have a documented emergency plan in place to mitigate the effects on people and the environment in the event of a release of anhydrous ammonia into the atmosphere. Ammonia is also flammable at concentrations of approximately 15% to 28% by volume in air. %���� 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. Ammonia is the lifeblood of many chilling systems but it can also be lethal. 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. Chemical treatments for this are available and the advice of suppliers should be rigorously respected. <> 10 0 obj This guidance may go further than the minimum needed to comply with the law. endobj Also, the plan is evidence that the person in control of the workplace complies with work health and safety laws.
