10. STABILITY AND REACTIVITY
Chemical Stability: Stable under recommended storage conditions. Avoid excess heat and incompatible materials.
Conditions to Avoid: Oxidizing agents, aluminum (at high temperatures), and diazomethane
Hazardous Decomposition Products:
Local exhaust ventilation recommended. Running water should be available in case material gets in eyes. Wash
hands, forearms, and face thoroughly after handling chemical products, before eating, smoking, and using the
lavatory and at the end of the working period. Wash clothing before reusing.
Thermal decomposition may produce: calcium oxide, nitrogen
oxides, carbon oxides, sulfur oxides, and hydrogen cyanide.
Store in a cool, dry, well ventilated location. Do not store near aluminum (at high temperatures), diazomethane,
oxidizing agents or other incompatible materials. Keep away from moisture.
Eating, drinking, and smoking should be prohibited in areas where this material is handled or stored. Do not ingest and avoid contact with
skin and eyes. Avoid breathing in dust. Wear appropriate respirator when ventilation is inadequate.
A NIOSH (US) or CEN (EU) approved particulate respirator is recommended where total dust
concentration exceeds 10 mg/m
