Refrigerant classification is based on the safety of the refrigerant used. Standard 15 draws refrigerant safety classification from ANSI/ASHRAE Standard 34, which classifies refrigerants by toxicity and flammability into one of six categories (see Figure 1). All of the refrigerants shown in Figure 2 are Class A (lower toxicity) and
