The Environmental Protection Agency (EPA) is an agency of the United States government. The EPA is responsible for protecting the environment and human health from the effects of pollution and other environmental factors.

As part of its mission to protect the environment, the EPA has been actively involved in the study of refrigerants, which are used in air conditioning and refrigeration systems.

This practice test is a study tool for anyone who wants to obtain a license from the EPA to work in the refrigerant-related field.

The questions in this practice test have been carefully selected and arranged in a way that will make your studying easier and more fun.
