Honeywell – DuPont Confidential

DuPont and Honeywell feel comfortable with all toxicity test results conducted to date and will continue the commercialization of HFO-1234yf for use in MAC

Based on toxicity testing conducted to date, including the second

species developmental and the 2-generation reproductive (1-

generation interim results) studies, we believe HFO-1234yf will not

be classified as a developmental or reproductive toxin, and it will

likely be classified as ASHRAE Class A (low toxicity).

There appear to be no health safety hazards or properties that

would preclude the safe use of HFO-1234yf in MAC applications.
