When you are dealing with this chemical, you should be very careful. This chemical has an extremely low flash point, boiling point and gases can catch fire in contact with air. It may catch fire in contact with air, only need brief contact with an ignition source and have a very low flash point or evolve highly flammable gases in contact with water. In addition, it may destroy living tissue on contact and it may form explosive peroxides. This chemical is harmful by inhalation, in contact with skin and if swallowed and its repeated exposure may cause skin dryness or cracking. Therefore, you should wear suitable protective clothing, gloves and eye/face protection. You should keep away from sources of ignition and take precautionary measures against static discharges. In case of contacting with eyes, you should rinse immediately with plenty of water and seek medical advice. And in case of accident or if you feel unwell seek medical advice immediately.
