4 FIRST AID MEASURES
General measures: Under normal handling and use, exposure to the solid forms of this material does not present a health risk. However, during operations such as grinding, melting or welding, potentially hazardous dust or fumes may be produced, thereby causing inhalation or contact with skin or eyes.
INHALATION: Transfer the individual to fresh air, keep warm and calm, and administer oxygen if breathing difficulties occur. Seek medical advice.
INGESTION: Rinse the mouth with water. Do not induce vomiting. Seek medical assistance. Never induce vomiting or administer anything by mouth to an unconscious individual.
SKIN: Remove contaminated clothing, brush the material from the skin and wash the affected area with water and soap. If symptoms occur or persist, seek medical advice.
EYES: Rinse the eyes with lukewarm water for at least 15 minutes, ensuring the water cleans beneath both the upper and lower eyelids. If symptoms occur or persist, consult a doctor.

Principal symptoms/effects, acute and delayed: May cause irritation. See Section 11 for further information.
Advice on urgent medical treatment and special treatment: No further pertinent information is available.

5 FIRE FIGHTING MEASURES
Extinguishing media: Use an extinguishing agent suitable for the surrounding materials and the type of fire.
Unsuitable extinguishing media: No information available
Specific hazards arising from the material: In its supplied state, this product presents no fire or explosion hazard. Fine chips and dust generated during processing may be flammable and, under fire conditions, could release toxic metal oxide fumes.
Special protective equipment and precautions for fire-fighters: Use full-face protection, a self-contained breathing apparatus and complete protective clothing, if required.

6 ACCIDENTAL RELEASE MEASURES
Personal precautions, protective equipment and emergency procedures: Wear appropriate respiratory and protective equipment as detailed in Section 8. Avoid the generation of dust.
Methods and materials for containment and cleaning up: Sweep or scoop up the material and place it into a suitable disposal container.
Environmental precautions: Prevent release into the environment.

7 HANDLING AND STORAGE
Precautions for safe handling: Avoid dust formation. Ensure adequate ventilation if dust is produced. Avoid inhaling dust or fumes and prevent contact with skin and eyes. Wash thoroughly before eating or smoking. Refer to Section 8 for details of personal protective equipment.
Conditions for safe storage: Store in a cool, dry place. Refer to Section 10 for further information on incompatible materials.

8 EXPOSURE CONTROLS / PERSONAL PROTECTIVE EQUIPMENT
Exposure limit values: Tantal
OSHA/PEL: 5 mg/m³
ACGIH/TLV: 5 mg/m³
Technical protective measures: Ensure sufficient ventilation to maintain exposures below the occupational limits. Where practicable, use local exhaust or other engineering controls to reduce airborne dust and fume concentrations. Maintain good housekeeping and hygiene practices. Prevent dust accumulation, as it may constitute a fire hazard. Do not smoke or eat in the work area. Wash thoroughly before eating or smoking. Do not use compressed air to remove dust from clothing or skin.
Respiratory protection: If exposure limits are exceeded, use a NIOSH-approved respirator.
Eye protection: Safety goggles
Skin protection: Wear impervious gloves and, where necessary, protective occupational clothing.
