10. STABILITY AND REACTIVITY
Chemical Stability:
Conditions to Avoid:
Hazardous Decomposition Products:
Thermal decomposition may produce: sulfur dioxide, calcium oxide,
nitrogen oxides, carbon oxides, sulfur oxides, and hydrogen cyanide.
Stable under recommended storage conditions. Avoid excess sources of ignition, heat,
and incompatible materials. Dust suspended in air is readily ignited.
Oxidizing agents, aluminum (at high temperatures), diazomethane, heat, sparks, open
flame, static electricity, or any other potential ignition source.
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.
