Class I refrigerants have an ozone depletion potential (ODP) greater than what value?

Class I refrigerants are known for their significant impact on the ozone layer, possessing an ozone depletion potential (ODP) that is greater than 0.1. This classification includes substances such as chlorofluorocarbons (CFCs) and halons, which have been primarily targeted for phase-out due to their harmful effects on ozone depletion.

The threshold of 0.1 is critical because any refrigerant exceeding this value is considered to contribute significantly to ozone layer damage. Thus, it is accurate to say that Class I refrigerants have an ODP greater than 0.1. This understanding is fundamental for technicians, as it underlines the importance of handling and using refrigerants responsibly, in compliance with regulations aimed at protecting the environment.

The other choices reflect higher values, but they do not align with the defining characteristic that classifies a refrigerant as Class I. While they may be valid figures in other contexts, the defining benchmark for identifying Class I refrigerants is firmly established at 0.1.
