| Fire Fighting Measures | Back to Contents | 【Flash Point】
123 | 【Autoignition】
240 | 【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: Use agent most appropriate to extinguish fire. | 【Fire Potential】
This material is probably combustible. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
3 | 【Incompatibilities】
Flammable and/or toxic gases are generated by the combination with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents Can react with air to give first peroxo acids, and ultimately carboxylic acids Strong oxidizing acids may cause a vigorous reaction that is sufficiently exothermic to ignite the reaction products. | 【Stability】
Stable under normal temperatures and pressures. | 【Decomposition】
Irritating and toxic fumes and gases. |
