Volkswagen Golf Service & Repair Manual: Safety precautions when handling refrigerants

Risk of freezing injury caused by refrigerant
When working on the air conditioning system, there is a risk of highly pressurised refrigerant escaping from the system. There is a risk of injury to the skin and parts of the body due to freezing.
–  Always wear safety gloves.
–  Always wear safety goggles.
–  Extract refrigerant, and open the refrigerant circuit immediately afterwards.
–  If more than 10 minutes passed since the refrigerant has been extracted, do not open the refrigerant circuit prior to extracting refrigerant anew. Due to re-evaporation, pressure will be built up in the refrigerant circuit.
 
 
     
Risk of damage to refrigerant lines
There is a risk of damage to the refrigerant lines due to rupture of the inner foil.
–  Never bend refrigerant lines to a radius less then 100 mm (r < 100 mm).
