NFPA 704
General Description
Light yellow to tan solid with a faint odor. Sinks and mixes with water. (USCG, 1999)
Hazards
Reactivity Alerts
none
Air & Water Reactions
Water soluble. Gradually darkens on exposure to air and/or light
Fire Hazard
Special Hazards of Combustion Products: Decomposes at 210° to carbon dioxide and pyrogallol, which can form irritating vapors. (USCG, 1999)
Health Hazard
Inhalation causes irritation of nose and throat, coughing, and sneezing. Ingestion may cause gastric disturbance. Contact with eyes causes irritation. (USCG, 1999)
Reactivity Profile
TANNIC ACID decomposes at 210°C to carbon dioxide and pyrogallol, which can form irritating vapors (USCG, 1999). Incompatible with salts of heavy metals, alkaloids, gelatin, albumin, starch, oxidizing substances-e.g., permanganates, chlorates; lime water [Merck].
