Salts, Acidic

Acidic salts, such as FERRIC FLUORIDE, 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. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. FERRIC FLUORIDE is used to catalyze organic reactions.

INHALATION: Inorganic fluorides are generally irritating. INGESTION: Ingestion of iron compounds can cause: lethargy, retching, vomiting, tarry stools, fast and weak pulse, low blood pressure, and coma. (USCG, 1999)

EYES: Flush with plenty of water for at least 15 minutes. Get medical attention. SKIN: Flush with soap and water. INGESTION: Give water, milk, or activated charcoal and induce vomiting. Sodium sulfate catharsis. (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.

/SIGNS AND SYMPTOMS/ Inhalation: Inorganic fluorides are generally irritating. Ingestion: Ingestion of iron compounds can cause lethargy, retching, vomiting, tarry stools, fast and weak pulse, low blood pressure and coma. /Inorganic fluorides/|/SIGNS AND SYMPTOMS/ Skin and eye contact may produce severe irritation and burns. Inhalation of dust may cause coughing, choking, and respiratory difficulty. At fire temperatures may produce coughing, choking, headache, tearing, dizziness, difficult respiration, and cyanosis.

Iron fluoride (FeF3): ACTIVE

Method 4500-fluoride ion C. Electrode Method for the determination of fluoride in water and wastewater. This method is suitable for fluoride concn from 0.1 to more than 10 mg/l. The fluoride electrode is a selective ion sensor. A synthetic sample containing 0.850 mg fluoride ion/l in distilled water was analyzed in 111 laboratories with relative standard deviation of 3.6% and relative error of 0.7%. /Fluoride/|Method 4500-Fluoride ion D. SPADNS Method. This is a colorimetric method based on the color developed upon addition of SPADNS solution and zirconyl acid reagent to fluoride containing sample. The reaction rate between fluoride and zirconium ion is influenced greatly by the acidity of the reaction mixture. If the proportion of acid in the reagent is incr, the reaction can be made almost instantaneous. This method is suitable only for concn in the range of 0.05 to 1.4 mg/l. A synthetic sample containing 0.830 mg fluoride ion/l and no interference in distilled water was analyzed in 53 laboratories with a relative standard deviation of 8.0% and a relative error of 1.2%. After direct distillation of the sample, the relative standard deviation was 11.0% and the relative error 2.4%. /Fluoride/|Method 4500-Fluoride ion E. Complexone Method for the determination of fluoride ions in potable, surface, and saline waters as well as domestic and industrial wastewaters. The sample is distilled and the distillate is reacted with alizarin fluorine blue-lanthanum reagent to form a blue complex that is measured colorimetrically at 620 nm. The range of method, which can be modified by using the adjustable colorimeter, is 0.1 to 2.0 mg fluoride/l. In a single laboratory, four samples of natural water containing from 0.40 to 0.82 mg fluoride/l were analyzed in septuplicate. Average precision was + or - 0.03 mg fluoride/l. To two of the samples, additions of 0.20 and 0.80 mg fluoride/l were made. Average recovery of the additions was 98%. /Fluoride/
