Safety Measures When Working On Vehicles With Air Conditioning System And When Using - Skoda Citigo 2012 Workshop Manual

1.14 Safety measures when working on ve‐
hicles with air conditioning system and
when using refrigerant R 134a
WARNING
It is recommended to hold an eye bath flask within reach. If
liquid refrigerant gets into the eyes rinse the eyes out with water
for approximately 15 minutes.
Subsequently apply eye drops and immediately contact a
physician, even if the eyes are not painful. The physician must
be informed that the frostbites were caused by refrigerant
R134a.
The physician must be informed that the frostbites were
caused by refrigerant R134a. If in spite of these safety meas‐
ures refrigerant comes into contact with other body parts, rinse
immediately with water for at least 15 minutes.
If in spite of these safety measures refrigerant comes into con‐
tact with other body parts, rinse immediately with water for at
least 15 minutes.
Work on the air conditioning refrigerant circuit must only be
carried out in well-ventilated areas. Existing workshop suction
systems must be switched on.
Refrigerant must not be stored in lower areas (e.g. cellars) or
related exits or window openings.
During paint repairs, the temperature of the objects placed in
the drying oven or in its pre-heating zone must not exceed max.
80 °C (because heating causes a strong overpressure in the
system that may result in the opening of the pressure relief
valve).

Never fill the containers completely with liquid refrigerant. With
sufficient expansion space (gas blanket) the container will
burst as the temperature rises with catastrophic consequences
⇒ "1.8 Properties of refrigerant R134a", page 7
Refrigerant containers (e.g. filling cylinders at the A/C Service
position) must never be heated considerably or be exposed to
direct sunlight see ⇒ "1.12 Using pressure tank", page 11
Under no circumstances should refrigerant be filled into sys‐
tems and reservoirs in which there is air (evacuate systems
and reservoirs before filling with refrigerant).
