Exposure Controls/Personal Protection
【Personal Protection】eyes: Wear appropriate protective eyeglasses or chemical safety ggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves and clothing to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin.

【Exposure Effects】May cause fetal effects.
【Poison Class】2 (Very strong toxins)
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. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam. Use agent most appropriate to extinguish fire.
【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】Clean up spills immediately, using the appropriate protective equipment. Sweep up, then place into a suitable container for disposal. Avoid generating dusty conditions. Provide ventilation.
Stability and Reactivity
【Stability】Stable under normal temperatures and pressures.
【Incompatibilities】Strong oxidizing agents.
【Decomposition】Hydrogen chloride, nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen.
【Combustion Products】Fire may produce irritating, corrosive and/or toxic gases.
