When you are dealing with this chemical, you should be very careful. This chemical is irritating to eyes, respiratory system and skin. 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. Therefore, you should wear suitable protective clothing. In case of contacting with eyes, you should rinse immediately with plenty of water and seek medical advice. What's more, you should keep away from sources of ignition.
