Extinguishing Media: Use suitable extinguishing media for surrounding material and type of fire.

Special Firefighting 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 and Explosion Hazards: Barium zirconate may emit toxic fumes 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 barium zirconate have not been thoroughly investigated and recorded.

              Barium compounds may cause severe gastroenteritis, including abdominal pain, vomiting and diarrhea, tremors, faintness, paralysis of the arms and legs, and slow or irregular heartbeat. Severe cases may produce collapse and death due to respiratory failure. Soluble barium compounds are more likely to cause these effects than insoluble compounds. Inhalation of fumes may cause sore throat, coughing, labored breathing, and irritation of the respiratory tract as well as the above symptoms.

              Zirconium compounds are not an important industrial poison. Most zirconium compounds in common use are insoluble and considered inert. Pulmonary granuloma in zirconium workers has been reported. (Sax, Dangerous Properties of Industrial Materials)

Acute Effects:

Inhalation: May cause irritation to the upper respiratory system, dizziness, nausea, vomiting, colic, diarrhea, rapid respiration, high blood pressure, irregular heart action, convulsions, paralysis and acute barium poisoning.

Ingestion: May cause irritation to the gastrointestinal tract, vomiting, colic, diarrhea, slow irregular pulse, transient hypertension, convulsions, tremors, muscular paralysis and acute barium poisoning.

Skin: May cause irritation.

Eye: May cause irritation.

Chronic Effects:

Inhalation: May cause pulmonary granulomas and chronic barium poisoning.

Ingestion: May cause chronic barium poisoning.

Skin: May cause skin granulomas and dermatitis.

Eye: May cause corneal opacity and blindness.

Medical Conditions Generally Aggravated By Exposure: Pre-existing respiratory disorders.

Target Organs: May affect the respiratory system, central nervous system, heart, skin and eyes.

Carcinogenicity: NTP: No           IARC: No          OSHA: No

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove victim to fresh air, keep warm and quiet, give oxygen if needed and seek immediate medical advice.

INGESTION: Give 1-2 glasses of milk or water and induce vomiting, seek medical attention. Never give anything by mouth or induce vomiting in an unconscious person.

SKIN: Remove contaminated clothing, brush material off skin, wash with soap and water, seek immediate medical advice.

EYE: Immediately flush eyes with lukewarm water for at least 15 minutes. Seek immediate medical advice.

VI         REACTIVITY DATA

Stability: Stable

Conditions to Avoid: None known

Incompatibility (Material to Avoid): Oxidizing agents

Hazardous Decomposition Products: Barium oxide, metal oxide fume.

Hazardous Polymerization: Will not occur

VII        SPILL OR LEAK PROCEDURES

Steps to Be Taken in Case Material Is Released or Spilled: Wear appropriate respiratory and protective equipment. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.

Waste Disposal Method: Dispose of in accordance with Local, State, and Federal regulations.

VIII      SPECIAL PROTECTION INFORMATION

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

Ventilation: Use local exhaust to maintain concentration below PEL, TLV. General exhaust is recommended.

Protective Gloves: Rubber 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: Store in a cool, dry area. Store in tightly sealed container. Wash thoroughly after handling. Store away from oxidizing agents.

Work Practices: Implement engineering and work practice controls to reduce an 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 safety drench shower, facilities for washing and eyewash capable of sustained flushing.
