When you are dealing with this kind of chemical, you should be cautious. For one thing, it is harmful which may cause damage to health. And this is irritating to skin and may have danger of cumulative effects. Besides, being very toxic to aquatic organisms, it may cause long-term adverse effects in the aquatic environment. 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. 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. What's more, it may cause lung damage if swallowed and the vapours may cause drowsiness and dizziness.

Therefore, you shuold avoid contacting with skin and eyes. If swallowed, do not induce vomiting, and you should seek medical advice immediately and show this container or label. Besides, avoid releasing to the environment and you could also refer to special instructions/safety data sheet. When store it, remember that this material and its container must be disposed of as hazardous waste.
