Safety & regulation
Safety information is for reference only and does not replace the supplier’s Safety Data Sheet (SDS), applicable regulations, or professional assessment.
Hazard information
Fire HazardsFlash point data for this chemical are not available; however, it is probably combustible. (NTP, 1992)
Health HazardsACUTE/CHRONIC HAZARDS: When heated to decomposition this compound emits toxic fumes of nitrogen oxides, phosphoric acid, carbon monoxide and carbon dioxide. (NTP, 1992)
Reactive GroupAmines, Phosphines, and Pyridines
Reactivity ProfileINDOL-3-YL SODIUM PHOSPHATE is incompatible with oxidizing agents. It is hydrolyzed rapidly by alkaline phosphatase to form a compound which is readily oxidized in solution by ambient oxygen under basic environment. (NTP, 1992)
Air and Water ReactionsIf left exposed to air for more than 120 minutes, it will turn to blue then black within 6 hours. Water soluble.
Safety & protection
Fire FightingFires involving this material can be controlled with a dry chemical, carbon dioxide or Halon extinguisher. A water spray may also be used. (NTP, 1992)
First Aid
EYES: First check the victim for contact lenses and remove if present. Flush victim's eyes with water or normal saline solution for 20 to 30 minutes while simultaneously calling a hospital or poison control center. Do not put any ointments, oils, or medication in the victim's eyes without specific instructions from a physician. IMMEDIATELY transport the victim after flushing eyes to a hospital even if no symptoms (such as redness or irritation) develop.
Nonfire Spill Response
SMALL SPILLS AND LEAKAGE: If you spill this chemical, you should dampen the solid spill material with water, then transfer the dampened material to a suitable container. Use absorbent paper dampened with water to pick up any remaining material. Seal your contaminated clothing and the absorbent paper in a vapor-tight plastic bag for eventual disposal. Wash all contaminated surfaces with a soap and water solution. Do not reenter the contaminated area until the Safety Officer (or other responsible person) has verified that the area has been properly cleaned.
