Air conditioning

First aid measures in case of accidents
– If accidental contact with escaping refrigerant has occurred,
take the following measures:
• Refrigerant, when in the form of a gas, and when heated
can, at low concentrations, have an effect, most particularly
on the nervous system. At high concentration, the gas has
a narcotic effect. In both cases, move personnel from the
danger area out into the fresh air. If someone is seriously
affected, seek medical advice.
• If large amounts of liquid refrigerant has come into contact
with unprotected skin, the injured area should be carefully
warmed with lukewarm water or covered with warm
clothes. Seek medical advice if there are remaining symp-
toms.
• If liquid refrigerant has come into contact with a person's
eyes, rinse the eyes with lukewarm running water. Seek
medical advice if there are remaining symptoms.
– Take the greatest care in all work with refrigerant.
– The AC system contains pressurized refrigerant. It is not al-
lowed to purposely release refrigerant into the environment. If
the air conditioning system has to be opened, the refrigerant
must first be collected in a special pressure vessel for re-use or
alternatively destruction.
– The AC system is pressurized and refrigerant can unintention-
ally leak. Never disconnect hoses and never remove the filler
plug on the compressor. If a leak is suspected, do not try to refill
the system. Contact an authorized Volvo dealer workshop for
them to take action.
– When carrying out work with emptying (discharging) or refilling
(charging) refrigerant, equipment specially intended for this
work must be used.
– The refrigerant vapour is heavier than air and will therefore sink
to the floor.
– Smoking, welding or other open flame are not permitted in the
place where work with refrigerant is carried out. The refrigerant
vapour could then be ignited, forming a poisonous gas which is
very dangerous to inhale. The gases formed when heated have
a pungent smell at high concentrations.
.
WARNING!
The gases can cause severe damage to lungs even at low
concentrations, when no smell is apparent. the symptoms
may arise several hours (even up to 24 hours) after
exposure to the gases.
