Low GWP Refrigerant Safety: Flammable and Mildly Flammable (A2L) Refrigerants
About this course
Why Low GWP Refrigerants?
To address the concerns of ozone depletion and global warming, many of the refrigerants that were used for decades are being phased out by the federal government. These older refrigerants are being replaced with more efficient and environmentally friendly refrigerants. Many of these refrigerants are classified by ASHRAE (American Society of Heating Refrigeration and Air Conditioning Engineers) as flammable. The refrigerants will require special safety training to handle them. This course will discuss refrigerant safety, refrigeration characteristics, proper installation and servicing guidelines, and more.
