When you are dealing with this chemical, you should be very careful. This chemical may cause damage to health and present an immediate or delayed danger to one or more components of the environment. 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. In addition, it has serious irreversible effects through inhalation, in contact with skin and if swallowed. The production is toxic to aquatic organisms and may cause long-term adverse effects in the aquatic environment. Therefore, you should keep container tightly closed and you should wear suitable protective clothing and gloves. What's more, you must keep away from sources of ignition and avoid releasing to the environment. In case of accident or if you feel unwell seek medical advice immediately.
