4 FIRST AID MEASURES
General Measures: This product in the form it is sold is not considered to constitute a physical hazard or a health hazard. Subsequent operations such as grinding, melting or welding may produce potentially hazardous dust or fumes which can be inhaled or come in contact with the skin or eyes.
INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult. Seek medical attention.
INGESTION: Rinse mouth with water. Do not 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 soap and water. Seek medical attention if symptoms persist.
EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms persist.
Most Important Symptoms/Effects, Acute and Delayed: May cause irritation. See section 11 for more information.
Indication of Immediate Medical Attention and Special Treatment: No other relevant information available.
5 FIREFIGHTING MEASURES
Extinguishing Media: Use suitable extinguishing media for surrounding material and type of fire.
Unsuitable Extinguishing Media: No information available.
Specific Hazards Arising from the Material: May emit toxic metal oxide fumes under fire conditions.
Special Protective Equipment and Precautions for Firefighters: Full face, self-contained breathing apparatus and full protective clothing when necessary.
6 ACCIDENTAL RELEASE MEASURES
Personal Precautions, Protective Equipment, and Emergency Procedures: Wear appropriate respiratory and protective equipment specified in section 8. Avoid dust formation. Avoid contact with skin and eyes. Avoid breathing dust or fume.
Methods and Materials for Containment and Cleaning Up: Sweep or scoop up. Place in a closed container for further handling and disposal.
Environmental Precautions: Do not allow to enter drains or to be released to the environment.
7 HANDLING AND STORAGE
Precautions for Safe Handling: Avoid breathing dust or fumes. Provide adequate ventilation if dusts or fumes are created. See section 8 for information on personal protection equipment.
Conditions for Safe Storage: Store in a sealed container. Store in a cool, dry area. See section 10 for more information on incompatible materials.
8 EXPOSURE CONTROLS AND PERSONAL PROTECTION
Exposure Limits: OSHA/PEL: ACGIH/TLV:
Tungsten 5 mg/m3 5 mg/m3
Thorium Dioxide No exposure limit established No exposure limit established
Engineering Controls: Ensure adequate ventilation to maintain exposures below occupational limits. Whenever possible the use of local exhaust ventilation or other engineering controls is the preferred method of controlling exposure to airborne dust and fume to meet established occupational exposure limits. 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.
Respiratory Protection: For processes that produce dust or fume, use a NIOSH approved dust, mist respirator. All appropriate requirements set forth in OSHA 29CFR 1910.134 should be met.
Eye Protection: Safety glasses
Skin Protection: Wear impermeable gloves, protective work clothing as necessary.

11 TOXICOLOGICAL INFORMATION
Likely Routes of Exposure: Inhalation, skin, eyes. Product as shipped does not present an inhalation hazard; however subsequent operations may create dusts or fumes which could be inhaled.
Symptoms of Exposure: Fumes/dusts may cause irritation.
Acute and Chronic Effects:
Tungsten: No data
Thorium Dioxide: Thorium dioxide is a naturally occurring, slightly radioactive element with a long half-life. It emits mainly alpha particles, but occasionally beta and gamma radiation is emitted. Alpha particles cannot penetrate skin or even paper and as such, its primary hazard lies in inhalation or ingestion. Normal handling of this material is not expected to result in any significant external radiation exposure. Considerable experience in refining and use of thorium has not revealed any adverse effects from industrial exposure. Thorium Dioxide has been identified as a carcinogen by the NTP and IARC. Evidence for its ability to cause cancer has come solely from its internal medical use.
Acute Toxicity: No data
Carcinogenicity: Thorium Dioxide: NTP: K - Known to be carcinogenic IARC: 2B - possibly carcinogenic to humans
To the best of our knowledge the chemical, physical and toxicological characteristics of the substance are not fully known.
