When you are dealing with this chemical, you should be very cautious. For one thing, it is irritant to eyes and skin and may cause inflammation to the skin or other mucous membranes. 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 very harmful. In addition, it is corrosive which may destroy living tissue on contact. Beside all these, 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.

Therefore, you should take the following instructions to protect yourself. Wear suitable protective clothing, gloves and eye/face protection. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice and if in case of accident or if you feel unwell seek medical advice immediately (show the label where possible). Then take off immediately all contaminated clothing. When storing it, take precautionary measures against static discharges and keep away from sources of ignition - No smoking.
