This is a kind of slightly yellow crystals and it is a harmful chemical. If by shock, friction, fire or other sources of ignition, it will have risk of explosion. Being irritant to eyes, respiratory system and skin, it is also harmful by inhalation and in contact with skin. As for these harmful properties, we need to be much more careful while using this chemical. First of all, wear suitable suitable protective clothing and gloves and eye/face protection, and if in case of contact with eyes, rinse immediately with plenty of water and seek medical advice. Secondly, this material and its container must be disposed of in a safe way and then avoid exposure - obtain special instruction before use. Besides, if in case of accident or if you feel unwell, seek medical advice immediately (show label where possible). And you could also refer to the WGK Germany 3 to get much more information.
