• Wear eye protection and protective gloves
• Avoid contact of liquid refrigerants with your skin (frost-
bite).
• Do not inhale refrigerant vapours.
• To avoid higher concentrations, all work rooms must
be ventilated very well. The opening of windows and
doors may not be sufficient, so an exhausting system
must be used directly at the supply point or near the
floor.
• Do not smoke, because fire might decompose the
refrigerant. The resulting substances are toxic and
must not be inhaled.
• Do not have refrigerants escaped during filling or re-
pair work. Cover with tape.
• Leave the room immediately and only enter after the
room has been sufficiently ventilated when refrigerant
concentrations (e.g. pipe line leakages) appear sud-
denly.
• Execute welding and soldering works on refrigerating
systems in well ventilated rooms only. Refrigerants
will be decomposed in flames as well as in electrical
arcs.
• The resulting decomposition products are toxic.
• Before welding and soldering at refrigerating systems,
the refrigerant must be removed.
• A stinking smell points to decomposition of refrigerant
due to overheating:
- leave room immediately
- ventilate room very well.
