When you are using this chemical, please be cautious about it as the following:
In case of inhalation, in contact with skin and swallow. It is easy to causes burns and it has the limited evidence of a carcinogenic effect. Contact with water will liberate toxic gas. It is harmful by inhalation and it reacts violently with water. In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Wear suitable protective clothing, gloves and eye/face protection. In case of accident or if you feel unwell seek medical advice immediately (show the label where possible). After contact with skin, wash immediately with plenty of ... (to be specified by the manufacturer). Take off immediately all contaminated clothing.
