HANDLING AND STORAGE
Cyanamide is to be handled in accordance with good industrial hygiene and safety practice. The most important precautions for production and lab work are:
?Avoid contact with skin and eyes.
?Wear suitable protective clothing and safety goggles.
?Avoid swallowing or inhaling.
?Use adequate ventilation.
?Do not drink alcoholic beverages before, during and after working and Cyanamide.
?Recommend the storage temperature from 5°C up to 10°C; for short period up to 25°C; avoid any temperature below -8°C.
?In no case apply storage temperatures above 40°C.
?Avoid prolonged storage over several months. In original drums, max. 3 months. Do not store surplus material.
?Do not try to purify Cyanamide by distillation, recrystallization, fractionation freezing or extraction. Spontaneous dimerization with an explosive heat release can result, because the stabilizer is removed.
?Do not add acidic or alkaline substances.
?Do not add strongly oxidizing agents.
?Store Cyanamide separately from alkaline, acids or oxidizing compounds.
