Chronic effects: Long-term exposure can lead to symptoms such as headaches, dizziness, loss of appetite, cough, nasal congestion, and chest pain.

Section 4: First Aid Measures

【Skin Contact】: Immediately remove contaminated clothing and rinse the affected area with plenty of flowing water for at least 15 minutes. Seek medical attention.

【Eye Contact】: Immediately lift the eyelids and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes. Seek medical attention.
【Inhalation】: Quickly leave the site to an area with fresh air. Keep the airway clear. If breathing is difficult, provide oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
【Ingestion】: Rinse mouth with water and give milk or egg white. Seek medical attention.

Section 5: Firefighting Measures
【Flash Point】: Not applicable
【Lower Explosive Limit】: Not applicable
【Ignition Temperature】: Not applicable
【Upper Explosive Limit】: Not applicable
【Extinguishing Method】: Firefighters must wear full acid and alkali resistant protective clothing. Extinguishing agent: dry sand.

Section 6: Emergency Response to Leaks

【Emergency Response to Leaks】: Isolate the contaminated area and restrict access. It is recommended that emergency responders wear dust masks and acid-alkali resistant work clothing. Do not directly touch the leaked material. For small leaks: Avoid dusting and collect with a clean shovel into a sealed container. For large leaks: Cover with plastic sheeting or canvas. Handle under expert guidance.
Section 7: Handling and Storage
【Storage and Transportation Precautions】: Store in a cool, dry, well-ventilated warehouse. Keep away from fire sources and heat sources. Maintain relative humidity below 75%. Packaging must be sealed and kept dry. Should be stored separately from flammable materials, alkalis, alcohols, etc., and avoid mixed storage. Not suitable for long-term storage to prevent deterioration. The storage area should be equipped with suitable materials to contain leaks. During railway transport, strictly follow the dangerous goods loading table in the Ministry of Railways' "Regulations on the Transport of Dangerous Goods". Ensure packaging is intact at departure, and loading is secure. During transport, ensure containers do not leak, topple, fall, or get damaged. Mixing with flammable or combustible materials, alkalis, alcohols, or edible chemicals is strictly prohibited. Transport vehicles should be equipped with leak emergency response equipment. Protect from exposure to sunlight, rain, and high temperatures during transport.

Section 8: Exposure Controls/Personal Protection
