Health hazards with the refrigerant
The refrigerant has only a very low acute health hazard. It has narcotic effects only at extremely high concentrati-
ons. After acute exposure to extremely high concentrations the substance is eliminated over the lungs very quik-
kly. The refrigerant has a certain irritating effect on skin and mucous membranes. Exposure of the skin to liquid
refrigerant can cause frost bite. In the presence of open fl ames or hot surfaces refrigerant can decompose and form
toxic decomposition products (e.g. hydrogyn chloride, phosgene). The refrigerant evaporates when exposed to air
. Intentional exposure of refrigerant is not permissible. The chiller must be handled with great care to prevent any
damage occuring through transport operations.
