| Fire Fighting Measures | Back to Contents | 【Autoignition】
398 | 【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 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. |
| Stability and Reactivity | Back to Contents | 【Incompatibilities】
Moisture, strong oxidizing agents. | 【Stability】
Stable at room temperature in closed containers under normal storage and handling conditions. | 【Decomposition】
Hydrogen chloride, nitrogen oxides, carbon monoxide, carbon dioxide. | 【Combustion Products】
Irritating fumes of hydrogen chloride may form in fires. |
