Description of key information

HFO-1234ze did not cause skin irritation in rabbit skin following 60 sec, 3 minutes, or 4 hours of exposure.  No dedicated studies are available for the evaluation of the eye irritating potential of HFO-1234ze. However, acute exposure up to 270000 ppm and repeated inhalation exposure up to 15000 ppm HFO-123ze did not show signs of eye, skin or respiratory irritation.

Additional information

Justification for classification or non-classification

No skin irritation was observed in rabbit skin following 60 sec, 3 minute or 4 hour dermal exposure to HFO-1234ze. Therefore classification and labelling for irritation/corrosion is not warranted in accordance with EU Classification, Labelling and Packaging of Substances and Mixtures (CLP) Regulation No. 1272/2008 and its amendments.
