Health hazards with the refrigerant
The refrigerant has only a very low acute health hazard. It has narcotic effects only at extremely high
concentrations. After acute exposure to extremely high concentrations the substance is eliminated over
the lungs very quickly. The refrigerant has a certain irritating effect on skin and mucous membranes. Ex-
posure 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.
