Hazards Identification | Back to Contents | 【Ingestion】
The toxicological properties of this substance have not been fully investigated. May be harmful if swallowed. | 【Inhalation】
The toxicological properties of this substance have not been fully investigated. Inhalation of dust may cause respiratory tract irritation. | 【Skin】
No information regarding skin irritation and other potential effects was found. | 【Eyes】
This product contains an anionic dye. Similar dyes have not caused injury to the cornea or conjunctiva in documented exposure cases with human or rabbit eyes. | 【Hazards】
Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. | 【UN (DOT)】

Fire Fighting Measures | Back to Contents | 【Fire Fighting】
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dusts at sufficient concentrations can form explosive mixtures with air. 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 chemical foam. | 【Fire Potential】
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. |
Stability and Reactivity | Back to Contents | 【Stability】
Stable; however, material can decompose above 251C (484F). | 【Incompatibilities】
Strong oxidizing agents | 【Decomposition】
Nitrogen oxides, carbon monoxide, oxides of sulfur, carbon dioxide, sodium oxide. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
