of Entry: Inhalation.
to Animals: Acute oral
toxicity (LD50): 17000 mg/kg [Rat].
Effects on Humans: Not
Toxic Effects on Humans: Slightly
hazardous in case of skin contact (irritant), of ingestion, of inhalation.
Remarks on Toxicity to Animals: Not
Remarks on Chronic Effects on Humans: Not
Remarks on other Toxic Effects on Humans:
Potential Health Effects: Skin: Causes mild skin irritation. May cause
dermatitis. Eyes: Causes mild eye irritation. Ingestion: May cause irritation of
the digestive tract and may cause purging. It is slowly aborbed. Expected to be
a low ingestion hazard for usual industrial handling. Ingestion of large doses
may affect behavior/central nervous system (tetany). However, if a significant
amount of phosphate is absorbed, hypophosphatemia will occur. Severe
hypophosphatemia may result in hypocalcemia and tetany. Cardiovasular,
respiratory, neurologic, and musculoskeletal effects may occur secondary to
hypernatremia, hypophosphatemia, and hypocalcemia Inhalation: May cause
respiratory tract and mucous membrane irritation. Low hazard for usual
industrial handling. Chronic Potential Health Effects: Skin: High and repeated
exposure may cause dermatitis.
