    Safety Safety regulations Safety data: R410A Refrigerant data Toxicity Contact with skin If sprayed, the refrigerant is likely to cause frost burns. If absorbed by the skin, the danger is very limited; it may cause a slight irritation, and the liquid is degreasing. Unfreeze the affected skin with water. Remove the contaminated clothes with great care - in the presence of frost burns, the clothes may stick to the skin.
  • Page 10 Safety General precautions Do not inhale concentrated vapours. Their concentration in the atmo- sphere should not exceed the minimum preset values and should be maintained below the professional threshold. Being more weighty than the air, the vapour concentrates on the bottom, in narrow areas. There- fore, the exhaust system must work at low level.
