Refrigeration System Hazards and Safety System Requirements

Описание: This webinar explores the key hazards associated with different types of refrigerants and the safety systems required to manage those risks in commercial and industrial refrigeration applications. Refrigerant selection is influenced by factors such as cost, direct and indirect greenhouse gas emissions (Scope 1 & 2), and inherent safety risks. For example, while toxic refrigerants like ammonia are unsuitable for domestic use, flammable refrigerants have been deemed acceptable. In systems with larger refrigerant charges, careful design and the inclusion of robust safety measures become critical. The session will examine the characteristics of commonly used refrigerants, assess the associated hazards such as toxicity, flammability, and high pressure and outline the engineering controls and regulatory requirements that help ensure safe operation.
