IV         FIRE AND EXPLOSION HAZARD DATA

Flash Point: N/E or N/A                                                                                        Method Used: Non-flammable

Explosive Limits: Lower: N/A     Upper: N/A

Extinguishing Media: Use suitable extinguishing media for surrounding materials 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 Hazard: Calcium 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 calcium zirconate have not been thoroughly investigated and recorded.

.             Generally speaking, calcium compounds should be considered toxic only when they contain toxic components or as calcium oxide or hydroxide. Calcium compounds are common air contaminants. (Sax, Dangerous Properties of Industrial Materials, eight edition.)

              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.

Acute Effects:

Inhalation: May cause irritation to the respiratory tract, mucous membranes of the nose and throat.

Ingestion: May cause irritation to the gastrointestinal tract.

Skin: May cause irritation.

Eye: May cause irritation.

Chronic Effects:

Inhalation: No chronic health effects recorded.

Ingestion: No chronic health effects recorded.

Skin: May cause skin granulomas.

Eye: No chronic health effects recorded.

Target Organs: May affect the respiratory system and skin.

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

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 breathing is difficult and seek medical attention.

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

SKIN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water , seek medical attention if symptoms persist.

EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.

VI         REACTIVITY DATA

Stability: Stable

Conditions to Avoid: None

Incompatibility ( Material to Avoid): Strong oxidizing agents and acids.

Hazardous Decomposition Products: None recorded.

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 specified in Section VIII. 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 Federal, State and Local regulations.

VIII      SPECIAL PROTECTION INFORMATION

Respiratory Protection: NIOSH-approved dust respirator.

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

Protective Gloves: Rubber gloves

Eye Protection: Safety glasses.

Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.

IX         SPECIAL PRECAUTIONS

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

Work/Hygienic/Maintenance 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 and smoking. Do not blow dust off clothing or skin with compressed air.

              Some of the chemicals listed herein are research or experimental substances which may be toxic, as defined by various governmental regulations. In accordance with Environmental Protection Agency regulations and the Toxic Substance Control Act (TSCA), these materials should only be handled by, or under the direct supervision of, a “technically qualified individual” , as defined in 40 CFR 710.2(aa).
