|The substance is toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.|
|Cyanamide has to be stabilized by pH-buffer against dimerization and decomposition.
An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
Cyanamide that has been stored for a long time or is contaminated, should be diluted with at least three times its volume of water to avoid critical decomposition temperatures being reached.
Do NOT take working clothes home.
Term cyanamide is also used to designate calcium cyanamide.
In combination with even small amounts of alcohol the substance causes effects on cardiovascular and central nervous systems resulting in flushing, palpitation, hypotension and hyperventilation.
