When you are dealing with this chemical, you should be very careful. This chemical 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. It may cause damage to health at low levels and it has serious damage to eyes. In addition, it is toxic by inhalation, in contact with skin and if swallowed. Therefore, you must keep away from sources of ignition. You should wear suitable protective clothing, gloves and eye/face protection. 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.
