4 FIRST AID MEASURES
General Measures: Under normal handling and use, exposure to solid forms of this material presents few health hazards. Subsequent operations such as grinding, melting, or welding may produce potentially hazardous dust or fumes that can be inhaled or come in contact with the skin or eyes.
INHALATION: Remove to fresh air, keep warm and quiet, and 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 the skin, and wash the affected area with soap and water. Seek medical attention if symptoms develop or persist.
EYES: Flush eyes with lukewarm water, including under upper and lower eyelids, for at least 15 minutes. Seek medical attention if symptoms develop or 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 is available.

5 FIREFIGHTING MEASURES
Extinguishing Media: Use a suitable extinguishing agent for surrounding materials and type of fire.
Unsuitable Extinguishing Media: No information available
Specific Hazards Arising from the Material: This product does not present fire or explosion hazards as shipped. Fine turnings and dust from processing may be ignitable. 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.
Methods and Materials for Containment and Cleaning Up: Sweep or scoop up. Place in appropriate waste disposal container.
Environmental Precautions: Do not allow it to be released into the environment.

7 HANDLING AND STORAGE
Precautions for Safe Handling: Avoid creating dust. Provide adequate ventilation if dust is created. Avoid breathing dust or fumes. Avoid contact with skin and eyes. Wash thoroughly before eating or smoking. See section 8 for information on personal protection equipment.
Conditions for Safe Storage: Store in a cool, dry area. See section 10 for more information on incompatible materials.

8 EXPOSURE CONTROLS AND PERSONAL PROTECTION
Exposure Limits: Tantalum
OSHA/PEL: 5 mg/m3
ACGIH/TLV: 5 mg/m3
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 allow dust to accumulate as it may present a fire hazard. Do not use tobacco or food in the work area. Wash thoroughly before eating or smoking. Do not blow dust off clothing or skin with compressed air.
Respiratory Protection: If permissible levels are exceeded, use NIOSH approved dust respirator.
Eye Protection: Safety glasses
Skin Protection: Wear impermeable gloves, and protective work clothing as necessary.
