Skin Contact
Liquid splashes or spray may cause freeze burns. Unlikely to be hazardous by skin absorption
.
Eye Contact
Liquid splashes or spray may cause freeze burns.
Ingestion
Highly unlikely - but should this occur freeze burns will result.
Long Term Exposure
HFC 32:
An inhalation study in animals has shown that repeated exposures produce no significant
effects (49,500ppm in rats).
HFC 125:
An inhalation study in animals has shown that repeated exposures produce no significant
effects (50,000ppm in rats).
HFC 134a:
A lifetime inhalation study in rats has shown that exposure to 50,000ppm resulted in benign
tumors of the testis. The increased tumor incidence was observed only after prolonged
exposure to high levels, and is considered not to be of relevance to humans occupationally
exposed to HFC 134a at or below the occupational exposure limit.
ECOLOGICAL INFORMATION
Environmental Fate and Distribution
High tonnage material produced in wholly contained systems. High tonnage material used in open systems.
Vapor.
Persistence and Degradation
HFC 32: Decomposed comparatively rapidly in the lower atmosphere (troposphere). Atmospheric lifetime is
5.6 year(s). Has a Halocarbon Global Warming Potential (HGWP) of 0.15 (relative to a value of 1 for CFC 11)
or a Global Warming Potential (GWP) of 650 (relative to a value of 1 for carbon dioxide at 100 years).
HFC 125: Decomposed slowly in the lower atmosphere (troposphere). Atmospheric lifetime is 32.6 year(s).
Has a Halocarbon Global Warming Potential (HGWP) of 0.70 (relative to a value of 1 for CFC 11) or a Global
Warming Potential (GWP) of 2800 (relative to a value of 1 for carbon dioxide at 100 years).
HFC 134a: Decomposed comparatively rapidly in the lower atmosphere (troposphere). Atmospheric lifetime
is 13.6 year(s). Has a Halocarbon Global Warming Potential (HGWP) of 0.30 (relative to a value of 1 for CFC
11) or a Global Warming Potential (GWP) of 1300 (relative to a value of 1 for carbon dioxide at 100 years).
HFC 32, HFC 125, HFC 134a: Do not influence photochemical smog (i.e. they are not VOCs under the terms of
the UNECE agreement). Do not deplete ozone.
