Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses, continue rinsing and seek medical attention immediately.
Ingestion: Rinse mouth with water, never give anything by mouth to an unconscious person, do not induce vomiting, seek immediate medical attention
Symptoms: Sore throat, cough, shortness of breath, burning sensation, nausea, vomiting, diarrhea, abdominal pain, green-blue vomiting (indicative of copper salts)

5. Fire-Fighting Measures

Extinguishing Media: Use water spray, alcohol-resistant foam, dry chemical, or carbon dioxide
Specific Hazards: Non-flammable under normal conditions, emits toxic fumes (including hydrogen chloride, copper oxides) if heated or involved in a fire
Protective Equipment: Firefighters should use self-contained breathing apparatus and full protective clothing
Advice: Contain runoff to reduce environmental contamination, avoid inhaling dust, use extinguishing agents that do not scatter dust

6. Accidental Release Measures

Personal Precautions: Wear appropriate PPE (gloves, goggles, lab coat, dust mask), avoid contact with eyes, skin, and clothing. Ventilate area.
Environmental Precautions: Prevent further leakage or spillage if safe to do so, do not allow to enter drains, sewers, or watercourses.
Methods for Cleaning Up: Scoop up spilled material carefully using tools that do not produce dust, place in a suitable container for disposal. Clean spill area thoroughly with water.
Decontamination: Wash surfaces with plenty of water after removing bulk material.

7. Handling and Storage

Handling: Use in a chemical fume hood or well-ventilated area, avoid generating dust, do not ingest, avoid inhalation, wear suitable protective clothing
Storage: Store in tightly closed containers in a cool, dry, well-ventilated location away from incompatible materials (such as strong acids, bases, and oxidizers). Ensure containers are labeled clearly, check containers for leaks regularly, protect from physical damage and moisture

8. Exposure Controls and Personal Protection

Occupational Exposure Limits: ACGIH TLV for copper (dust and mist) - 1 mg/m³ (TWA)
Engineering Controls: Use local exhaust ventilation, safety showers, and eye wash stations
Personal Protective Equipment (PPE): Safety goggles, chemical-resistant gloves, protective clothing, dust mask or respirator approved for chemical dust
