4. Safety Information of Ethyl difluoroacetate (CAS No. 454-31-9)

(1). Irritant. For being irritating to eyes and respiratory system, Ethyl difluoroacetate may cause inflammation to the skin or other mucous membranes, and it may toxic by inhalation.
(2). Corrosive: This chemcial may destroy living tissue on contact. And it is irritating to respiratory system.
(3). Toxic. Ethyl difluoroacetate could at low levels cause damage to health.
(4). Highly flammable: This chemcial may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water. And it could causes burns.
Therefore, you should take the following measure to prevent from danger. Wear suitable protective clothing, gloves and eye/face protection, and take off immediately all contaminated clothing when contact. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice; If in case of accident or if you feel unwell seek medical advice immediately (show the label where possible). Besides, keep away from sources of ignition - No smoking.

5. Use of Ethyl difluoroacetate (CAS No. 454-31-9)
