INFORMATION
In halation
High exposure may cause an abnormal heart rhythm and prove suddenly fatal.
Very high atmospheric concentrations may cause anesthetic effects and
asphyxiation.
Skin Contact
Liquid splashes or spray may cause freeze burns. Unlike 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
HFC32: An inhalation study in animals has shown that repeated exposures
produce no significant
Effects -49500ppm in rats
HFC 125: An inhalation study in animals has shown that repeated exposures
produce significant
Effects -50000ppm in rats

Persistence and Degradation
HFC32: Decomposed comparatively rapidly in the lower
atmosphere(troposphere) .
Atmospheric lifetime is 5.6 year(s)
Has a Global Warming Potential (GWP) of 650(relative to a value of 1 for
carbon dioxide at 100 year (s)
HFC 125: Decomposed slowly in the lower atmosphere (proposphere) .
atmospheric lifetime is 32.6 year(s)
Has a Global Warming Potential (GWP) of 2800(relative to a value of 1 for
carbon dioxide at 100 year (s)
HFC32 , HFC 125: Does not influence photochemical smog( i.e. is not a Voc
under the terms of the UNECE agreement). Does not deplete ozone
