– Purity/concentration: [Specific purity or concentration]
- First aid measures
– Skin contact: Immediately remove contaminated clothing and rinse with plenty of running water. Seek medical attention.
– EYE CONTACT: Immediately lift eyelids and flush thoroughly with large amounts of running water or saline for at least 15 minutes. Seek medical attention.
– INHALATION: Remove quickly from scene to fresh air. Keep airway open. If breathing is difficult, administer oxygen. If breathing stops, administer artificial respiration immediately. Seek medical attention.
– Ingestion: Rinse mouth with water and give milk or egg white. Seek medical attention.
- Fire-fighting measures
– Fire extinguishing agent: Use water, foam, dry powder, carbon dioxide, sand to extinguish fire.
– Fire-fighting precautions: Firefighters should wear gas masks and full body fire suits, and extinguish the fire in the upwind direction.
- Emergency Response to Leakage
– Emergency action: Isolate the leakage contaminated area and restrict access. It is recommended that emergency personnel wear dust masks (full face masks) and gas suits. Collect in dry, clean, covered containers with clean shovels and transfer to a safe place. If a large number of leaks, collect and recycle or transport to a waste disposal site for disposal.
VII. Operation, Disposal and Storage
– Precautions for operation: operate in airtight condition and strengthen ventilation. Operators must be specially trained and strictly follow the operating procedures. It is recommended that operators wear self-absorbing filtering dust masks, chemical safety glasses, anti-poison penetration work clothes and rubber gloves. Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Avoid contact with oxidizers and acids. Load and unload lightly when handling to prevent damage to packaging and containers. Equip with appropriate varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may retain harmful substances.
– Storage Precautions: Store in a cool, ventilated warehouse. Keep away from fire and heat source. It should be stored separately from oxidizers and acids, and should never be mixed. The storage area should be equipped with suitable materials to shelter the leakage.
VIII. Exposure control and individual protection
– Engineering control: closed operation, strengthen ventilation.
– Respiratory protection: When the concentration of dust in the air exceeds the standard, self-priming filtering dust mask must be worn. Emergency situation rescue or evacuation, should wear air respirator.
– Eye protection: Wear chemical safety glasses.
– Body protection: Wear anti-poison penetration work clothes.
– Hand protection: Wear rubber gloves.
