Water soluble.

Salts, Acidic

Acidic salts, such as FERRIC AMMONIUM OXALATE, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. Many of these compounds catalyze organic reactions. Special Hazards of Combustion Products: Toxic oxides of nitrogen, ammonia, and carbon monoxide may form in fires (USCG, 1999). This compound is a weak reducing agent, and may release carbon dioxide upon reaction with oxidizing agents.

SRP: The most favorable course of action is to use an alternative chemical product with less inherent propensity for occupational exposure or environmental contamination. Recycle any unused portion of the material for its approved use or return it to the manufacturer or supplier. Ultimate disposal of the chemical must consider: the material's impact on air quality; potential migration in soil or water; effects on animal, aquatic, and plant life; and conformance with environmental and public health regulations.

SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.|All ... /iron/ preparations should be kept in child-proof bottles. /Iron preparations/

Irritating to eyes, nose & throat. /Trihydrate/|Inhalation of ferric salts as dusts and mists is irritating to the respiratory tract. Ferric salts are regarded as skin irritants. /Iron salts/|If inhaled, iron is a local irritant to the lung and gastrointestinal tract. /Iron compounds/

Persons in charge of vessels or facilities are required to notify the National Response Center (NRC) immediately, when there is a release of this designated hazardous substance, in an amount equal to or greater than its reportable quantity of 1000 lb or 454 kg. The toll free number of the NRC is (800) 424-8802; In the Washington D.C. metropolitan area (202) 426-2675. The rule for determining when notification is required is stated in 40 CFR 302.4 (section IV. D.3.b).

Inhalation of dust may cause irritation of nose and throat. Ingestion causes burning pain in throat and stomach; mucous membranes become white; may also cause vomiting, weak pulse, cardiovascular collapse, and death. Contact with dust irritates eyes and skin; may cause severe skin burns. (USCG, 1999)

(treat victim promptly) INHALATION: move to fresh air; get medical attention if any symptoms persist. INGESTION: give immediately a dilute solution of any soluble calcium salt such as calcium lactate, limewater, chalk, or milk; induce vomiting; get medical attention. (Watch for edema of the glottis and delayed constriction of esophagus.) EYES: flush with water and get medical attention. SKIN: flush with water. (USCG, 1999)

Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patient can swallow, has a strong gag reflex, and does not drool. /Iron and related compounds/|Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Monitor cardiac rhythm and treat arrhythmias if necessary ... . Start an IV with lactated Ringer's /SRP: "To keep open", minimal flow rate/. Watch for signs of fluid overload. For hypotension with signs of hypovolemia, administer fluid cautiously. Watch for signs of fluid overload ... . Use proparacaine hydrochloride to assist eye irrigation ... . /Iron and related compounds/|Maintain an open airway and assist ventilation if necessary. Treat shock caused by hemorrhagic gastrointestinitis aggressively with intravenous crystalloid fluids, and replace blood if needed. Patients are often markedly hypovolemic owing to gastrointestinal losses and third spacing of fluids into the intestinal wall and interstitial space. Treat coma, seizures, and metabolic acidosis if they occur. For seriously intoxicated victims (eg, shock, severe acidosis, and/or serum iron > 500-600 mcg/dL) administer deferoxamine. Monitor the urine for the urine for the characteristic orange or pink deferoxamine-iron complex. Therapy may be stopped when the urine returns to normal or when the serum iron level decreases to the normal range. Prolonged deferoxamine has been associated with adult respiratory distress syndrome and Yersinia sepsis.|Activated charcoal is not effective. Ipecac is not recommended, because it can aggravate iron-induced gastrointestinal irritation and interfere with whole bowel irrigation. Consider gastric lavage if product was a liquid formulation or tablets were chewed. Do-not use phosphate-containing solutions for lavage; these may result in life-threatening hypernatremia, hyperphosphatemia, and hypocalcemia. Bicarbonate and deferoxamine lavage are of doubtful efficacy. Deferoxamine lavage is not effective and may enhance iron absorption. Whole-bowel irrigation is very effective for ingested tablets and may be considered first-line treatment, especially if large numbers of tablets are visible on plain abdominal x-ray. Massive ingestions may lead to concretions or bezoars. Repeated or prolonged whole-bowel irrigation may remove tablets. Endoscopy or surgical gastrotomy is rarely required.|Hemodialysis and hemoperfusion are not effective for removing iron but may be necessary to remove iron-deferoxamine complex in patients with renal failure. Exchange transfusion is occasionally used for massive pediatric ingestions but is of questionable efficacy.
