【Exposure Effects】Effects may be delayed.
Fire Fighting Measures
【Fire Fighting】Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Extinguishing media: Do NOT get water inside containers. In case of fire use water spray, dry chemical, carbon dioxide, or appropriate foam.
【Fire Potential】Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
Accidental Release Measures
【Small spills/leaks】Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.

【Incompatibilities】Moisture, strong oxidizing agents, strong acids.
【Stability】Stable at room temperature in closed containers under normal storage and handling conditions. Hygroscopic: absorbs moisture or water from the air.
【Decomposition】Nitrogen oxides, carbon monoxide, carbon dioxide, nitrogen.
【Combustion Products】Fire may produce irritating, corrosive and/or toxic gases.
