Regulatory Information
Hazard Traits - Carcinogenicity
Nitrilotriacetic acid, trisodium salt, monohydrate: Does not have an individual approval but may be used under an appropriate group standard
Fire Hazards
Literature sources indicate that this chemical is noncombustible. (NTP, 1992)
Combustible under specific conditions. Gives off irritating or toxic fumes (or gases) in a fire. Finely dispersed particles form explosive mixtures in air.
Health Hazards
SYMPTOMS: Symptoms of exposure to this compound may include irritation of the skin and eyes. Other symptoms may include irritation of the nose and throat. Contact with the powder or its dusts may result in irritation of the respiratory tract. Prolonged eye contact may lead to transient corneal injury. Ingestion causes gastric disturbances, burns to the gastrointestinal tract and vomiting. Ingestion of large amounts may cause hypocalcemic tetany with spontaneous recovery. Inhalation of the dust may cause coughing, wheezing, respiratory distress and mucous membrane irritation.
Hazards Summary
A corrosive substance that can cause injury to the skin, eyes, and respiratory tract; Possible human carcinogen; [ICSC] Positive evidence of carcinogenicity in rats produced at one laboratory, while another produced equivocal evidence in rats and negative evidence in mice; [NTP] Causes changes in renal tubules and changes in calcium oral repeated-dose studies of rats; [RTECS] A strong eye irritant; Harmful by ingestion; Suspected carcinogen; [Alfa Aesar MSDS] See Trisodium nitrilotriacetate.
