Skin Contact
Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorp on
.
Eye Contact
Liquid splashes or spray may cause freeze burns.
Inges on
Highly unlikely - but should this occur freeze burns will result.
Long Term Exposure
HFC 32:
An inhala on study in animals has shown that repeated exposures produce no signi
fi
cant
e
ff
ects (49,500ppm in rats).
HFC 125:
An inhala on study in animals has shown that repeated exposures produce no signi
fi
cant
e
ff
ects (50,000ppm in rats).
HFC 134a:
A life me inhala on study in rats has shown that exposure to 50,000ppm resulted in benign
tumors of the tes s. The increased tumor incidence was observed only a er prolonged
exposure to high levels, and is considered not to be of relevance to humans occupa onally
exposed to HFC 134a at or below the occupa onal exposure limit.
ECOLOGICAL INFORMATION
Environmental Fate and Distribu on
High tonnage material produced in wholly contained systems. High tonnage material used in open systems.
Vapor.
Persistence and Degrada on
HFC 32: Decomposed compara vely rapidly in the lower atmosphere (troposphere). Atmospheric life me is
5.6 year(s). Has a Halocarbon Global Warming Poten al (HGWP) of 0.15 (rela ve to a value of 1 for CFC 11)
or a Global Warming Poten al (GWP) of 650 (rela ve to a value of 1 for carbon dioxide at 100 years).
HFC 125: Decomposed slowly in the lower atmosphere (troposphere). Atmospheric life me is 32.6 year(s).
Has a Halocarbon Global Warming Poten al (HGWP) of 0.70 (rela ve to a value of 1 for CFC 11) or a Global
Warming Poten al (GWP) of 2800 (rela ve to a value of 1 for carbon dioxide at 100 years).
HFC 134a: Decomposed compara vely rapidly in the lower atmosphere (troposphere). Atmospheric life me
is 13.6 year(s). Has a Halocarbon Global Warming Poten al (HGWP) of 0.30 (rela ve to a value of 1 for CFC
11) or a Global Warming Poten al (GWP) of 1300 (rela ve to a value of 1 for carbon dioxide at 100 years).
HFC 32, HFC 125, HFC 134a: Do not in
fl
uence photochemical smog (i.e. they are not VOCs under the terms of
the UNECE agreement). Do not deplete ozone.
