Extinguishing Media: Do not use water. Use suitable extinguishing media for surrounding materials and type of fire.

Special Fire Fighting Procedures: Firefighters must wear full-face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.

Unusual Fire & Explosion Hazard: Bismuth iodide may emit toxic fumes of hydrogen iodide if involved in a fire.

V           HEALTH HAZARD INFORMATION

Effects of Exposure:

              To the best of our knowledge the chemical, physical and toxicological properties of bismuth iodide have not been thoroughly investigated and reported.

              Bismuth and bismuth compounds are often poorly absorbed. Should absorption occur, however, exposure may cause loss of appetite, headache, skin rash, exodermatitis, kidney injury and jaundice. Repeated or prolonged exposure may cause a bismuth line or black spots on the gums, foul breath and salivation.

              Prolonged exposure to iodides may cause skin rash, running nose, headache and irritation of the mucous membranes. In severe cases the skin may show pimples, boils, redness, black and blue spots, hives and blisters. Iodides are readily diffused across the placenta.

Acute and Chronic Effects:

Inhalation: May result in inflammation, edema, and chemical pneumonitis. May cause coughing, wheezing, laryngitis, shortness of breath, headache, nausea and vomiting.

Ingestion: Swallowing will lead to a strong corrosive effect on mouth and throat and to the danger of perforation of esophagus and stomach.

Skin: May cause skin burns or irritation depending on the severity of the exposure.

Eye: Strong corrosive effect. May result in permanent damage and complete vision loss.

Carcinogenicity: No classification data available from EPA, IARC, NTP, OSHA or ACGIH.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove to fresh air; keep warm and quiet, give oxygen if breathing is difficult, seek immediate medical attention.

INGESTION: Do not induce vomiting. Give plenty of fluids and seek immediate medical attention.

SKIN: Remove any contaminated clothing, immediately wash with soap and water, rinse thoroughly. Seek immediate medical advice.

EYE: Flush with copious amounts of water for 15 minutes, seek medical attention.

VII        SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled: Keep unprotected persons away. Wear appropriate respiratory and protective equipment specified below. Isolate spill and provide adequate ventilation. Use a neutralizing agent. Sweep or scoop up and place in a closed container for proper disposal. Take care not to raise dust.

Waste Disposal Method: In accordance with Local, State and Federal Waste Disposal Regulations.

VIII      SPECIAL PROTECTION INFORMATION

Respiratory Protection (Specify Type): NIOSH approved dust-fume-mist cartridge respirator.

Ventilation: Use local exhaust to maintain concentration at low exposure levels. General exhaust is not recommended.

Protective Gloves: Impervious gloves

Eye Protection: Safety glasses

Other Protective Equipment: Protective gear suitable to prevent contamination.

IX         SPECIAL PRECAUTIONS

Precautions to Be Taken in Handling and Storage: Protect from water/moisture. Store in a cool, dry area. Store in tightly sealed container. Wash thoroughly after handling.

Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.
