What are the safety requirements for working with refrigerants?

The correct answer underscores the importance of adhering to regulations while ensuring personal safety when working with refrigerants. Following Environmental Protection Agency (EPA) guidelines is crucial since these regulations are designed to protect both the environment and the health of workers handling refrigerants, which can be harmful if not managed properly.

Using personal protective equipment (PPE) adds an additional layer of safety, shielding workers from potential exposure to chemicals and physical hazards associated with refrigerants. This includes gloves, goggles, and respiratory protection, depending on the job specifics, to minimize the risk of injury or adverse health effects.

Ultimately, this comprehensive approach ensures that all safety protocols are met, safeguarding both the technician and the environment from the risks associated with refrigerants.
