Handling refrigerants (DX units)

According to EN 378, refrigerants are divided in groups, concerning health and safety: R410A
belongs to group L1 (non-flammable, non-toxic).
•
Adherence to the regulations by law and guide-lines
•
Execution only by competent staff
•
Responsibility for correct disposal of refrigerant and system parts is incumbent on the
operator
•
Refrigerants have a narcotic effect when inhaled in high concentrations
•
The room is to be evacuated immediately if high concentrations of refrigerant suddenly
occur. The room may only be entered again after adequate ventilation.
•
If unavoidable work is required in presence of a high concentration of refrigerant, breathing
apparatus must be worn. This does not mean simple filter masks. Comply with breathing
protection data sheet.
•
Safety glasses and safety gloves are to be worn
•
Do not eat, drink or smoke at work
•
Liquid refrigerant must not get onto the skin
•
Only use in well ventilated areas
•
Do not inhale refrigerant vapours
•
Warn against intentional misuse
•
Remove refrigerant from the system before performing any welding or brazing works.
•
Weld and braze air conditioning systems without refrigerants only in suitably ventilated
rooms.
•
If the system emits a pungent smell this means that the refrigerant has decomposed due to
overheating. Immediately leave the room and return only after it has been suitably ventilated
or when wearing a gas mask for acid gases.
•
It is absolutely essential to comply with the first aid measures if accidents occur
•
Refrigerants containing FCs contribute to the global warming and with this to climate
changes. The FCs must therefore be disposed of in accordance with the regulations, i.e. only
by companies specially qualified and licensed as recognised disposal companies for
refrigerants
