4. First Aid Measures

Ingestion: Rinse mouth with water, never induce vomiting, seek immediate medical attention
Inhalation: Move affected individual to fresh air, loosen tight clothing, seek medical advice if symptoms persist
Skin Contact: Wash affected area with plenty of soap and water, remove contaminated clothing and footwear, consult a healthcare provider if irritation develops
Eye Contact: Rinse eyes carefully with water for several minutes, remove contact lenses if present, keep eyelids apart and flush with continuous water flow, seek medical attention promptly if irritation continues
Important Symptoms: Redness, itching, swelling of exposed tissues, coughing or shortness of breath possible after inhalation
Notes for Doctor: Symptomatic treatment, monitor for allergic reactions or respiratory complications

5. Fire-Fighting Measures

Suitable Extinguishing Media: Water mist, dry chemical, carbon dioxide, or foam
Unsuitable Media: Strong water jets as splashing may spread material
Specific Hazards: Thermal decomposition may produce nitrogen oxides, carbon oxides, irritating vapors or fumes
Firefighter Protection: Use self-contained breathing apparatus and full protective gear
Firefighting Advice: Cool exposed containers with water spray, stay upwind of fire

6. Accidental Release Measures

Personal Precautions: Use personal protective equipment, avoid breathing vapor or dust, ventilate area
Environmental Precautions: Prevent entry into waterways, drains, or soil
Containment: Collect spillage with inert absorbent material such as sand or diatomaceous earth, avoid raising dust
Clean-Up Methods: Transfer to a suitable container for proper disposal, wash spill area thoroughly, ventilate location
Notification: Report large spills to local authorities as required

7. Handling and Storage

Handling: Keep away from open flames, hot surfaces and sources of ignition, avoid formation of dust or aerosols
Safe Practices: Wear suitable personal protective equipment, work in a chemical fume hood
Hygiene: Do not eat, drink, or smoke while handling, always wash hands after use 
Storage Conditions: Store in tightly closed containers, in a dry, cool, and well-ventilated area, keep container upright and sealed
Incompatible Materials: Strong oxidizers, strong acids, alkali materials
Storage Life: Stable under recommended storage conditions, avoid exposure to direct sunlight, humidity

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: No OSHA PEL or ACGIH TLV established for this substance
Engineering Controls: Work in a properly functioning chemical fume hood, ensure local exhaust ventilation
Personal Protective Equipment: Wear chemical-resistant gloves (like nitrile), splash-proof safety goggles, lab coat or apron
Respiratory Protection: Use approved mask or respirator if dust or vapor concentrations exceed safe levels
Environmental Protection: Use closed systems or local exhaust, avoid release into environment
