| Refrigerants dissolve fats and oils pretty well. When in contact with the skin, therefore remove the protective fat film. However, degreased skin is sensitive to cold and disease germs. |
| Do not spill liquid refrigerant onto the skin. The heat to vapourize extracts the refrigerant from the surrounding area. Thus, very low temperatures can be achieved. This results in local frostbites (boiling point of R134a ambient pressure at -26.5°C). |
