PRECAUTIONS FOR HANDLING AND USE OF R134a
FLUIDS
Refrigerant fluids expand to the gaseous state in standard environmental conditions. In order
that they may be shipped and used they must be compressed into suitable bottles. We
therefore recommend observing all the general precautions applicable to handling of
pressurized containers. In the case of R134a in particular, we suggest the following special
precautions. Avoid inhaling highly concentrated vapors even for short periods of time, since
such vapors can cause loss of consciousness or death. R134a is not flammable, but if the
vapor is exposed to open flames or incandescent surfaces it may undergo thermal
decomposition and form acid substances. The acrid and pungent odor of these products of
decomposition is sufficient to signal their presence. We therefore recommend avoiding use of
R134a near open flames and incandescent elements. There exists no evidence of risks
deriving from transdermal absorption of R134a Nevertheless, due to the low boiling point of the
liquid, it is advisable to wear protective garments such as to ensure that no jets of liquid or gas
can come into contact with the skin. The use of goggles to avoid contact with the eyes is
especially recommended, since the refrigerant liquid or gas can cause freezing of the ocular
fluids. Moreover, we strongly advise users to avoid dispersing the R134a refrigerant fluid
utilized in the machine since it is a substance that contributes to raising the temperature of the
planet, with a global warming potential(GWP) of 1300.
RULES FOR WORKING WITH R1234yf FLUIDS
Under ambient conditions refrigerant fluids are gases. In order to be able to transport and use
them they must be compressed in specific bottles. The precautions for pressure vessels must
therefore be applied.
In particular, for R1234yf be careful of the following situations:
-
Inhalation of vapours at very high concentrations, even for short periods of time, must be
avoided as it can cause unconsciousness and sudden death.
-
R1234yf is flammable and if the vapour is exposed to naked flames or red hot surfaces it
can undergo thermal decomposition with the formation of acid products. The acrid, pungent
odour of these products of decomposition is sufficient to warn of their presence. Avoid
finding yourself in the conditions just mentioned.
-
There is no proof of risks resulting from the absorption of R1234yf through the skin,
however, due to its low boiling point it is advisable to wear protective clothing that can
prevent any liquid sprayed or vapour reaching the skin and especially the eyes, where they
could cause the eye fluids to congeal.
-
We also recommend no dispersing the R1234yf refrigerant fluid used in the machine,
because it is a substance that contributes to heating the planet, with a global warming
potential (GWP) of 4.
ANY USE THAT DIFFERS FROM THAT JUST DESCRIBED IS NOT ALLOWED BY THE
MANUFACTURER.
