- 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 rinse 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 extinguishing precautions: Firefighters must wear gas masks, full body fire suits, and extinguish the fire in the upwind direction.
Sixth, leakage emergency treatment
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. Use clean shovels to collect in dry, clean, covered containers 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
Closed operation, 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: Confined operation, strengthen ventilation.
Respiratory protection: When the concentration of dust in the air exceeds the standard, self-priming filtering dust masks must be worn. Air respirator should be worn when rescuing or evacuating from an emergency situation.
Eye protection: Wear chemical safety glasses.
Body protection: Wear anti-poison penetration work clothes.
Hand protection: Wear rubber gloves.
Other Protection: Smoking, eating and drinking are prohibited at the work site. Shower and dress after work. Maintain good hygienic habits.
