When you are dealing with this chemical, you should be very careful and then take some measures to protect yourself. For one thing, it is toxic which could at low levels cause damage to health.  It will have danger of very serious irreversible effects through inhalation, in contact with skin and if swallowed. Besides, it may cause cancer. For another thing, it is dangerous for the environment which may present an immediate or delayed danger to one or more components of the environment. This is very toxic to aquatic organisms. In addition, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source, and its has a very low flash point or evolve highly flammable gases in contact with water.

Due to so many dangers, you should take the following instructions to protect yourself. Wear suitable protective clothing, gloves and eye/face protection. If iin case of accident or if you feel unwell seek medical advice immediately (show the label where possible), and if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Besides, avoid exposure – obtain special instructions before use. And while keeping it, keep container tightly closed, away from sources of ignition – No smoking. Lastly, remember not to release to the environment, and you could also refer to special instructions/safety data sheet.
