| Fire Fighting Measures | Back to Contents | 【Flash Point】
136 | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Water runoff can cause environmental damage. Dike and collect water used to fight fire. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. To extinguish fire use water spray, dry chemical, carbon dioxide, or chemical foam. Use agent most appropriate to extinguish fire. | 【Fire Potential】
May burn but does not ignite readily. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Vacuum or sweep up material and place into a suitable disposal container. Clean up spills immediately, using the appropriate protective equipment. Avoid generating dusty conditions. Provide ventilation. |
| Stability and Reactivity | Back to Contents | 【Stability】
Stable at room temperature in closed containers under normal storage and handling conditions. Deliquescent; tends to lose ammonia. | 【Incompatibilities】
Strong oxidizing agents, strong acids, moisture. | 【Decomposition】
Nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, ammonia. | 【Combustion Products】
Irritating vapors of ammonia acetic acid, and nitrogen oxides may form in fires. |
