4. FIRST-AID MEASURES

General advice: Seek immediate medical attention. Show this SDS to medical personnel.

Inhalation: Remove to fresh air immediately. If breathing is difficult, administer oxygen by trained personnel. Seek medical attention.

Skin contact: Remove contaminated clothing. Wash skin thoroughly with soap and water. Seek medical attention.

Eye contact: Rinse cautiously with water for at least 15 minutes. Remove contact lenses if present. Seek medical attention.

Ingestion: Rinse mouth. Do NOT induce vomiting. Seek immediate medical attention.

Most important symptoms/effects: Toxic if inhaled or swallowed. Kidney damage, lung damage, and delayed systemic effects are possible.

5. FIRE-FIGHTING MEASURES

Suitable extinguishing media: Dry chemical, dry sand, alcohol-resistant foam. Use a water spray to cool containers.

Specific hazards: Strong oxidizer. May intensify fire. Thermal decomposition releases nitrogen oxides and uranium oxides.

Protective equipment: Self-contained breathing apparatus and full protective gear.

6. ACCIDENTAL RELEASE MEASURES

Personal precautions: Evacuate area. Avoid dust formation. Use respiratory protection.

Environmental precautions: Prevent release to drains, soil, or waterways.

Cleanup methods: Carefully collect material using non-sparking tools. Place in a sealed container for disposal.

7. HANDLING AND STORAGE

Handling: Avoid contact with skin and eyes. Avoid dust formation. Use local exhaust ventilation.

Storage: Store tightly closed in a cool, dry, well-ventilated area. Keep away from combustible materials. Hygroscopic.

Specific end uses: No other uses are stipulated apart from the uses mentioned in section 1.
