3. Hazards Identification

Emergency Overview: WARNING: Corrosive if ingested. Skin and eye irritant. Persons attending the patient should avoid direct contact with heavily contaminated clothing and vomitus. Wear impervious gloves while decontaminating skin and hair. Remove patient from the source of exposure and confirm that the individual is breathing.

Potential Health Effects:

  • Signs and Symptoms of Acute Overexposure: Irritation of exposed tissues
  • Signs and Symptoms of Chronic overexposure: NDA
  • Medical Conditions Generally Aggravated by Exposure: NDA

4. First Aid Measures

  • Inhalation: Remove patient to fresh air. Get medical attention, if patient experiences breathing difficulty.
  • Ingestion: Do not induce vomiting. Give patient large quantity of water to drink to dilute the product. If vomiting occurs, give more water to drink. Get immediate medical attention.
  • Skin Contact: Remove  contaminated clothing and footwear. Wash skin with water until slippery feeling is gone. Get medical attention if irritation persists. Wash clothing before reuse. If clothing is heavily contaminated, dispose of clothing in a manner which limits further exposure. Get medical attention immediately.
  • Eye Contact: Immediately flush eyes with water for 15 minutes. Get immediate medical attention.
  • Note to Physician: No specific antidote available. All treatments should be based on observed signs and symptoms of distress in the patient. Consideration should be given to the possibility that overexposure to materials other than this product may have occurred. The principal manifestation of overexposure is corrosion. Treat asphyxia from glottal edema by maintaining an adequate airway. Treat shock - maintain normal blood pressure by transfusion and by the administration of 5% dextrose in saline. If symptoms are severe and perforation of the stomach or esophagus is suspected, give nothing by mouth until an endoscopic examination has been done. Maintain nutrition by giving carbohydrate or hyperalimentary fluid intravenously. Give prednisolone, 2 mg/kg/day in divided doses for 10 days to reduce the progression of fibrocystic and hyaline lung disease. Esophageal stricture may require dilation.

6. Accidental Release Measures

Persons involved with cleanup should wear appropriate protective equipment. Ventilate spill area.To the extent possible, clean up spillage using shovels. Carefully scoop up loose material and place it in appropriate containers so as to avoid dust generation. Stand upwind if possible. Neutralize residue with dilute acid and flush spill area with water. If spilled on the ground, the affected area should be scraped clean and the material placed in an appropriate container for disposal. Do not flush material to public sewer systems or any waterways. Ensure adequate decontamination of tools and equipment following clean-up. Large spills should be handled according to a predetermined plan.
