  • Health hazards: Acute poisoning can occur when inhaling the vapors of this product. Signs of poisoning include severe vomiting and diarrhea; dilated pupils and unresponsiveness to light, blurred vision, malaise, and speech disorders. In human patch tests, 25% of the solution causes severe skin irritation and may cause allergic reactions.
  • Environmental Hazards:
  • Detonation Hazards:This product is flammable, corrosive, irritating, can cause burns to the human body, and is sensitizing.

Part IV: First aid measures

  • Skin Contact: Remove contaminated clothing immediately and rinse with plenty of running water for at least 15 minutes. Seek medical attention.
  • Eye Contact: Immediately lift eyelids and rinse thoroughly with plenty of running water or saline solution for at least 15 minutes. Seek medical attention.
  • Inhalation: Remove from scene quickly to fresh air. Keep airway clear. If breathing is difficult, administer oxygen. If respiration stops, resuscitate immediately. Get medical attention
  • Medical.
  • Ingestion: Rinse mouth with water, give milk or egg whites. Seek medical attention.

Part V: Fire Fighting Measures

  • Hazard characteristics:Flammable, flammable in open flame and high heat. Highly toxic fumes when heated. Reacts violently in contact with oxidizers. The vapor is heavier than air and can spread at low altitudes over long distances, catching fire when ignited.
  • Hazardous combustion products: carbon monoxide, carbon dioxide, nitrogen oxide.
  • Extinguishing Method: Spray the escaping liquid with water to dilute it into a non-combustible mixture and protect firefighters with a mist of water.
  • Extinguishing agent: water, anti-soluble foam, dry powder, carbon dioxide, sand.

Part VI: Emergency response to spills

  • Emergency treatment: Quickly evacuate the spill contaminated area to a safe area, and isolate, strictly limit access. Cut off the fire source. It is recommended that emergency responders wear self-contained positive pressure respirators and anti-acid and alkali work clothes. Enter the scene from upwind. Cut off the source of leakage as much as possible. Prevent leakage into restricted spaces such as sewers and flood drains. Small spills: mix with sand, dry lime or soda ash. It can also be flushed with large amounts of water, which can be diluted and placed in the wastewater system. Large spills: construct berms or dig pits to contain them. Cover with foam to reduce vapor damage. Transferred by explosion-proof pump to tanker truck or special collector for recycling or transport to waste disposal site.

Part VII: Operational Disposal and Storage

  • Operating Notes:Sealed operation, with attention to ventilation. Operators must be specially trained to strictly follow the operating procedures. It is recommended that operators wear a direct gas mask (half mask), chemical safety glasses, anticorrosive overalls, and rubberized oil-resistant gloves. Keep away from fire and heat sources, and do not smoke in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from leaking into the workplace air. Avoid contact with acids. Load and unload gently to prevent damage to packaging and containers. Have the appropriate variety and quantity of fire-fighting equipment and spill response equipment. Emptying containers may leave hazardous residues.
  • Storage Precautions:Store in a cool, well-ventilated warehouse. Keep away from fire and heat sources. Storage temperature should not exceed 30°C. Keep containers sealed. Should be stored separately from acids and edible chemicals, do not mix them. Use explosion-proof lighting and ventilation facilities. Do not use spark-prone mechanical equipment and tools. The storage area should be equipped with leak emergency treatment equipment and suitable shelter materials.
