Handling refrigerators safely is crucial to ensure both personal safety and environmental protection. Technicians must be properly trained to handle different types of refrigerants, including the use of appropriate personal protective equipment (PPE) such as gloves, goggles, and respirators when necessary. Safety protocols include ensuring proper ventilation in work areas, avoiding refrigerant leaks, and using the correct tools for recovery, charging, and evacuation. It is important to adhere to regulations, such as the correct disposal of refrigerants and using certified equipment for leak detection and recovery. Additionally, technicians should be aware of the properties of each refrigerant type, including its flammability, toxicity, and pressure characteristics, to minimize risks and ensure safe handling throughout the installation, servicing, and maintenance processes.
