Give cardiopulmonary resuscitation (CPR) if there is no breathing AND no pulse. Obtain medical attention IMMEDIATELY. Inhalation: Start flushing while removing contaminated clothing. Wash affected areas thoroughly with soap and water. If irritation, redness, or a burning sensation develops and persists, obtain medical advice. Skin Contact: Immediately flush eyes with running water for a minimum of 20 minutes. Hold eyelids open during flushing. If irritation persists, repeat flushing. Obtain medical attention IMMEDIATELY. Eye Contact: Do not attempt to give anything by mouth to an unconscious person. If victim is alert and not convulsing, rinse mouth out and give 1/2 to 1 glass of water to dilute material. DO NOT induce vomiting. If spontaneous vomiting occurs, have victim lean forward with head down to avoid breathing in of vomitus, rinse mouth and administer more water. Obtain medical attention IMMEDIATELY. Ingestion: Sodium Tripolyphosphate : If a large quantity has been ingested, test for hypocalcemia, and treat with 10 ml. of 10 % calcium gluconate by slow intravaenous infusion, if necessary. (3) Treatment of large quantity phosphate salts ingestion should take into consideration both anionic and cation portion of the molecule. The following treatments should be considered for the specified group(s) of the phosphate salts found in this product: All phosphate salts, except calcium salts, have a hypothetical risk of hypocalcemia, so calcium levels should be monitored. Sodium salts have a hypothetical risk of hypernatremia. In addition to calcium levels, sodium and phosphate levels should be monitored. (3) Medical conditions that may be aggravated by exposure to this product include diseases of the skin, eyes or respiratory tract, asthma and bronchitis. Note to Physicians: This product may cause mild gastrointestinal discomfort. Ingestion of very high levels may cause diarrhea, nausea and vomiting, bluish lips and skin, low blood pressure and kidney damage. Ingestion of large quantities of phosphate salts (over 1.0 grams for an adult) may cause an osmotic catharsis resulting in diarrhea and probable abdominal cramps. Larger doses such as 4-8 grams will almost certainly cause these effects in everyone. In healthy individuals most of the ingested salt will be excreted in the feces with the diarrhea and, thus, not cause any systemic toxicity. Doses greater than 10 grams hypothetically may cause systemic toxicity. (3) Phosphate salts have been studied extensively since they are used in food additives. Toxic effects on the kidney, parathyroid glands and bones have been reported in experimental animals exposed to high oral doses. These high doses are not considered relevant to occupational exposure. (4) Ingestion: Effects (irritancy) on the skin and eyes may be delayed. Strict adherence to first aid measures following any exposure is essential. May cause hypocalcemia, hypernatremia, shock, low blood pressure, weak pulse, cyanosis and kidney damage. Cyanosis is characterized by navy blue, almost black lips, tongue, and mucous membranes, with skin colour being slate gray. Further manifestation is characterized by headache, weakness, dyspnea, dizziness, stupor, respiratory distress and death due to anoxia. Signs and symptoms of kidney damage generally progress from oliguria, to blood in the urine, to total renal failure. Since phosphates are slowly and incompletely absorbed [in the gut], systemic reactions are unlikely when these salts are swallowed. Polyphosphates are thought to be hydrolyzed to orthophosphates before absorption, which may induce a metabolic acidosis. If appreciable amounts of the intact polymer are absorbed from the alimentary tract, hypocalcemic tetany (muscular contraction, pains, tingling, etc., caused by a deficiency of calcium salts) may be a danger due to the binding of ionized calcium. (3) All phosphate salts, except calcium salts, have a hypothetical risk of hypocalcemia. (8) Hypocalcemia is characterized by abnormally low levels of Calcium in the circulating blood. Sodium salts have a hypothetical risk of hypernatremia. Hypernatraemia is a term that describes an abnormally high plasma concentration of sodium ions. This condition may lead to weakness, restlessness, dizziness, headache, convulsions and coma. (4) Other Health Effects: 5.
