What is the primary reason for technicians to use protective equipment like gloves and goggles?

The primary reason technicians are trained to use protective equipment such as gloves and goggles is to ensure safety while handling hazardous materials. In the context of refrigerants like R-410A, technicians often come into contact with chemicals that can cause skin irritation, eye injury, or other health risks if proper precautions are not taken. Protective gear acts as a barrier against these potential hazards, reducing the chance of injury.

While looking professional and meeting customer expectations are important aspects of a technician's role, they do not directly address the health and safety concerns that arise when working with hazardous substances. Additionally, compliance with company attire pertains more to workplace standards than to personal safety. Overall, the use of protective equipment is a critical practice for maintaining technician safety and health in the face of potential risks associated with their work environment.
