  • Ingestion: Drink water, do not induce vomiting. Give milk or egg whites. Seek medical attention.

(5) Fire Fighting Measures

  • Hazardous characteristics: Flammable in open flame and high heat. Toxic gases are emitted by high heat decomposition. Chemical reactions can occur in contact with strong oxidizers.
  • Hazardous combustion products: carbon monoxide, sulfur oxide, hydrogen chloride.
  • Fire extinguishing method: dry powder, carbon dioxide, sand.
  • Fire extinguishing precautions and measures: Firefighters must wear full body acid and alkali resistant firefighting suits and wear air breathing apparatus to extinguish fires. As far as possible, move the container from the fire scene to an open area. Spray water to keep the container cool until the fire is extinguished. Do not use water, foam or acid/alkaline agents to extinguish fires.

(6) Spill response

  • Emergency Actions: Quarantine spill contaminated area and restrict access. Eliminate all ignition sources. It is recommended that emergency responders wear dust masks, hazmat suits, and rubber gloves. All equipment used in the operation should be grounded. Do not touch or cross spills. Disconnect the source of the spill whenever possible. Cover spills with plastic sheeting to reduce dispersion. Do not allow water to enter the container. Collect spills with a clean scoop, place in a clean, dry container with a loose lid, and move the container away from the spill area.

(7) Handling disposal and storage

  • Operating Precautions: Sealed operation, providing adequate local exhaust ventilation. Operators must be specially trained to strictly follow the operating procedures. It is recommended that operators wear self-absorbing filtered dust masks, chemical safety glasses, anti-toxic permeation overalls, and rubber gloves. Keep away from fire and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation systems and equipment. Avoid generating dust. Avoid contact with oxidizers and alkalis. 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 the container may leave harmful residues.
  • Storage Note: Store in a cool, dry, well-ventilated warehouse. Keep away from fire and heat sources. Package must be sealed and not exposed to moisture. Should be stored separately from oxidizers, alkalis, edible chemicals, do not mix storage. Equipped with corresponding varieties and quantities of fire-fighting equipment. The storage area should be equipped with suitable shelter materials.
