When you are dealing with this chemical, you should be very careful. For one thing, it is irritant which may cause inflammation to the skin or other mucous membranes and it is irritating to eyes, respiratory system and skin. For another thing, it is harmful which may cause damage to health. If by inhalation, in contact with skin and if swallowed, it will be dangerous. In addition, it is highly flammable which 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.   

Due to so many dangers mentioned above, you should take different measures to deal with different cases. Wear suitable protective clothing and then take precautionary measures against static discharges. And if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Then remember to keep it away from sources of ignition - No smoking.
