However, we also recognize the ASHRAE Safety Standard for Refrigeration Systems. The purpose of this document is to help you understand those requirements and to outline what CETCI, as a manufacturer of gas detection systems, suggests for a mechanical refrigeration/ammonia applications.Īs a Canadian manufacturer, our suggestions comply primarily with the Mechanical Refrigeration Code published by the Canadian Standards Association (CSA). Included in the safety standards are specific requirements for the use of gas detectors. The goal of these safety standards is to keep the refrigerant/ammonia contained within the equipment and in the event that a leak does happen, mitigate the impact on people. There are safety standards in place for the design, construction and operation of mechanical refrigeration/ammonia systems. Understanding and Complying with the Gas Detection Specifications in the CSA and ASHRAE Safety Standards for Mechanical Refrigeration & Ammonia Systems
