First Aid Measures

Inhalation: Remove person to fresh air; seek medical attention if breathing difficulty continues
Skin Contact: Remove contaminated clothing; wash skin thoroughly with soap and water; get medical attention for continued irritation
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, lifting eyelids; seek medical help if irritation persists
Ingestion: Rinse mouth, offer small sips of water; do not induce vomiting; consult a doctor or poison center

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide, foam
Specific Hazards: May release irritating fumes such as carbon oxides during combustion
Protective Equipment: Use self-contained breathing apparatus and full protective gear
Special Procedures: Cool surrounding area and containers with water spray to prevent bursting

Accidental Release Measures

Personal Precautions: Avoid dust formation, ventilate area properly, use recommended PPE
Environmental Precautions: Prevent further leakage or spillage into drains or soil
Spill Cleanup Methods: Sweep up spilled material while minimizing dust formation; transfer into container for disposal; wash spill site after material pickup is complete

Handling and Storage

Handling: Keep containers tightly closed; work in well-ventilated spaces; avoid contact with skin and eyes; avoid inhaling dust
Storage: Store in a cool, dry, and well-ventilated location away from incompatible substances such as strong bases and oxidizing agents; keep container sealed when not in use

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust ventilation or process enclosures; keep airborne concentrations below recommended limits
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, lab coat
Respiratory Protection: Respirator with dust filter if exposure limits may be exceeded
Hygiene Measures: Wash hands after handling; do not eat, drink, or smoke in work area; remove contaminated clothing and wash before reuse
