  Safety Precautions General Practices Refrigerant 1. Always wear goggles or safety glasses. When removing any refrigerant from a unit, use a Refrigerant liquid and battery acid can recovery process that prevents or absolutely permanently damage the eyes (see First Aid minimizes the refrigerant that can escape to the under Refrigerant Oil).

• Page 14: Electrical

  Safety Precautions Use the following First Aid practices if needed. • Never work alone on high voltage circuits on the refrigeration unit. Another person should Immediately flush eyes with large amounts Eyes: always be standing by in the event of an of water for at least 15 minutes while holding the accident to shut off the refrigeration unit and eyelids open.
