3 COMPOSITION / INGREDIENT INFORMATION
Constituent: Tantalum
CAS No.: 7440-25-7
Percentage: 100
EC Number: 231-135-5

4 FIRST-AID MEASURES
Inhalation: Remove the person to fresh air. Maintain warmth and calm. If breathing difficulty persists, supply oxygen and seek medical advice.
Ingestion: Rinse mouth with water. Do not induce vomiting. Consult a doctor if irritation continues. Never induce vomiting or offer any substance to an unconscious person.
Skin contact: Remove contaminated clothing. Brush off the material from skin and wash the area with soap and water. Seek medical advice if irritation persists.
Eye contact: Rinse eyes with lukewarm water for at least 15 minutes, ensuring the upper and lower eyelids are flushed. Consult a doctor if irritation persists.
Primary symptoms/actions, both immediate and delayed: May cause irritation. See Section 11 for further details.
Medical advice: No additional pertinent data are available.

5 FIRE-FIGHTING MEASURES
Extinguishing media: Use a dry powder suitable for Class D materials.
Unsuitable media: Do not use water.
Specific hazards from the substance: Fine dust, if dispersed in sufficient concentration and exposed to an ignition source, may burn in outdoor settings or explode in confined areas. Burning may generate tantalum oxide fumes.
Protective equipment for firefighters: Use a full-face, self-contained breathing apparatus and complete protective clothing.

6 MEASURES FOR UNINTENTIONAL RELEASE
Personal precautions and protective equipment: Use appropriate respiratory and skin protection as described in Section 8. Eliminate all ignition sources. Isolate the spilled area and provide ventilation.
Methods for containment and cleaning: Avoid agitating the powder. Use only non-sparking tools and brushes with natural bristles. Vacuum the spilled powder with a device designed for combustible metal dust and equipped with a HEPA filter. Transfer the material into properly labelled, sealed containers.
Environmental precautions: Prevent the material from entering the sewage system or the environment.

7 HANDLING AND STORAGE
Safe handling: Process under a dry protective gas such as argon. Keep the material away from ignition sources. Avoid contact with skin and eyes. Prevent inhalation of dust and fumes. Ensure adequate local exhaust ventilation in areas where dust may be generated. Do not create dust clouds using brushes or compressed air. Do not smoke or eat in the working area. Wash thoroughly before eating or smoking. Refer to Section 8 for personal protective equipment information.
Safe storage conditions: Store in a cool, dry location. Keep the material in tightly closed, properly labelled containers, preferably under argon. Store separately from heat and ignition sources. Keep away from oxidising agents. See Section 10 for incompatible materials.

8 EXPOSURE CONTROL AND PERSONAL PROTECTIVE EQUIPMENT
Exposure limits: Tantalum
OSHA/PEL: 5 mg/m³
ACGIH/TLV: 5 mg/m³
Engineering controls: Handle fine powders under argon in a controlled, enclosed environment. Use local exhaust or similar controls to maintain exposure below the established workplace limits. Apply good hygiene practices at the worksite. Do not smoke or eat in the work area. Wash thoroughly before eating or smoking. Do not use compressed air to dislodge dust from clothing or skin.
Personal protective measures include:
- Respiratory protection: Use an appropriate respirator when dust levels are high.
- Eye protection: Safety goggles.
- Skin protection: Impervious gloves and, if necessary, protective work clothing.
