Refrigerant Safety in HVAC Systems

COURSE NO: M05-027
Refrigerant Safety in HVAC Systems
Course Highlights

This online engineering PDH course discusses the dangers of various refrigerants and provides information on precautionary guidelines, based on ASHRAE Standards 34 and 15, to prevent any potential accidents from occurring in the facility.


American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) defines a set of requirements that keep the personnel safe while working in mechanical rooms or any area in a building where refrigerants are involved.


All new machinery rooms containing refrigerant equipment, and the occupied spaces containing direct expansion (DX) type refrigeration systems, such as Variable Refrigerant Flow (VRF) systems, must be designed to comply with ASHRAE 15. It is important to note that the compliance with the ASHRAE 15 is mandatory, and failing to equip, train and protect working personnel and building occupants from the potential hazards of refrigerant gas leaks is a serious matter that can lead to civil or criminal penalties.


This 5 PDH online course is applicable to environmental and mechanical engineers who are interested in learning about ASHRAE standards 15 and 34, and understanding the potential hazards and safety precautions while working with refrigerants.
