Long Term Exposure
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
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).
Effect on Effluent Treatment
Discharges of the product will enter the atmosphere and will not result in long term aqueous contamination.
DISPOSAL CONSIDERATIONS
Best to recover and recycle. If this is not possible, destruction is to be in an approved facility which is equipped to absorb
and neutralise acid gases and other toxic processing products.
