3.2 First-Aid Measures

• Inhalation: Move victim to fresh air. If breathing is difficult, give oxygen. Seek medical attention immediately.
• Skin Contact: Remove contaminated clothing. Rinse skin thoroughly with plenty of water for at least 15 minutes. If irritation persists, seek medical help.
• Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, keeping eyelids open. Remove contact lenses if possible. Seek medical attention promptly.
• Ingestion: Do not induce vomiting. Give large amounts of water to dilute. Seek medical help immediately and bring this TDS.

3.3 Fire-Fighting Measures

• Suitable Extinguishing Media: Dry chemical powder, carbon dioxide (CO₂), foam, water spray.
• Unsuitable Extinguishing Media: High-pressure water jet (may spread the fire).
• Hazardous Combustion Products: Toxic gases such as chlorine, nitrogen oxides, and carbon monoxide may be released during combustion.
• Fire-Fighting Precautions: Firefighters must wear full protective equipment (including self-contained breathing apparatus) to avoid exposure to toxic fumes.

3.4 Accidental Release Measures

• Personal Precautions: Wear appropriate protective equipment (gloves, goggles, mask) to avoid direct contact or inhalation.
• Environmental Precautions: Prevent the spilled material from entering water bodies, sewers, or soil.
• Clean-Up Methods: Sweep up the spilled powder carefully and place it in a sealed container for proper disposal. Wash the contaminated area with water and detergent, and avoid the washing water entering the environment.

4. Handling and Storage

4.1 Handling Precautions

• Avoid contact with skin, eyes, and mucous membranes.
• Operate in a well-ventilated area (preferably under a fume hood).
• Do not generate dust during handling; avoid inhaling dust.
• Wash hands and face thoroughly after handling the product.

4.2 Storage Conditions

• Store in a cool, dry, well-ventilated warehouse away from direct sunlight.
• Keep the container tightly sealed when not in use to prevent moisture absorption and contamination.
• Store separately from oxidizing agents, acids, and food-grade materials to avoid chemical reactions or cross-contamination.
• The storage area should be equipped with appropriate fire-fighting equipment and emergency handling materials.

5. Exposure Controls/Personal Protection

• Engineering Controls: Install local exhaust ventilation systems to reduce air-borne dust concentration; ensure good ventilation in the workplace.
• Personal Protective Equipment (PPE):
  • Respiratory Protection: Wear a dust mask (N95 or higher grade) when dust is generated; use a self-contained breathing apparatus in case of heavy exposure.
  • Eye Protection: Wear chemical safety goggles to prevent eye contact.
  • Skin Protection: Wear nitrile or neoprene gloves; wear a chemical-resistant apron if necessary to avoid skin contact.
  • Clothing: Wear long-sleeved shirts and long pants to cover exposed skin.
• Hygiene Measures: Do not touch the face, mouth, or eyes with contaminated hands; change contaminated clothing promptly and wash it before reuse.

6. Stability and Reactivity

• Stability: Stable under normal temperature and pressure when stored and handled according to requirements.
• Conditions to Avoid: High temperature, open flame, strong oxidizing agents, and strong acids.
• Incompatible Substances: Oxidizing agents (such as potassium permanganate, hydrogen peroxide), strong acids (such as sulfuric acid, hydrochloric acid) — may cause violent reactions or decomposition.
• Hazardous Decomposition Products: Under high temperature or acidic conditions, it may decompose to release toxic gases such as chlorine and aniline derivatives.

7. Toxicological Information

• Acute Toxicity:
  • Oral toxicity: Harmful if swallowed (LD₅₀ not fully reported, but similar chlorinated phenylhydrazine compounds have moderate oral toxicity).
  • Dermal toxicity: May cause skin irritation; allergic reactions may occur in sensitive individuals.
  • Eye toxicity: Causes serious eye irritation; may lead to corneal damage if not treated promptly.
• Chronic Toxicity: Long-term exposure may cause damage to the liver, kidneys, or nervous system (limited data, refer to similar compounds).
• Sensitization: May cause skin sensitization in some people, leading to allergic dermatitis.

8. Ecological Information

• Aquatic Toxicity: Harmful to aquatic organisms (LC₅₀ for fish: <1 mg/L, 96h; EC₅₀ for algae: <1 mg/L, 72h — estimated data).
• Persistence and Degradability: Persistent in the environment; difficult to biodegrade under natural conditions.
• Bioaccumulation: May have a certain bioaccumulation effect in aquatic food chains (log Koc estimated to be 3-4, indicating moderate adsorption to soil).
• Environmental Precautions: Prevent the product from entering water bodies, soil, or atmosphere; avoid environmental pollution.

9. Disposal Considerations

• Waste Disposal: Dispose of the product and its containers in accordance with local, state, and national environmental protection regulations. Do not discard it as domestic waste.
• Contaminated Containers: Rinse the containers thoroughly before disposal; the rinsing water should be treated as hazardous waste. Do not reuse contaminated containers.
• Disposal Method: Incinerate the waste in a professional hazardous waste incineration plant equipped with exhaust gas treatment facilities to ensure that toxic gases are fully treated.

10. Transport Information

• UN Number: UN 2811 (Toxic solids, organic, n.o.s.)
• Transport Hazard Class: 6.1 (Toxic substances)
• Packing Group: III
• Transport Precautions:
  • Use sealed, corrosion-resistant packaging (such as fiber drums lined with plastic bags).
  • Mark the package with hazard signs (toxic substance signs) and transport labels in accordance with regulations.
  • Avoid mixing with food, feed, or consumer goods during transport.
  • Prevent sun exposure, rain, and high temperature during transport; avoid collision and damage to the package.
