Safety measures: Keep away from fire and heat sources, and smoking is strictly prohibited in the workplace. Avoid contact with eyes, skin, wash thoroughly after operation. Avoid breathing gas. Operate only outdoors or in well-ventilated areas. Wear protective gloves/protective clothing/eye protection/face shield. Discharge into the environment is prohibited.

Accident response: evacuate the personnel from the leakage pollution area to the safety area, and isolate them. Strictly limit and cut off the leakage source as much as possible to prevent entering into the restricted space such as sewer and flood discharge ditch. In case of skin contact, immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention. In case of eye contact, immediately lift the eyelid and rinse thoroughly with plenty of flowing water or saline for at least 15 minutes. Seek medical attention. If inhaled, quickly leave the site to fresh air. Keep the airway unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. Seek medical attention. If ingested by mistake, drink plenty of warm water, induce vomiting, and seek medical attention.

Safe storage: airtight operation, strengthen ventilation.

Disposal: refer to relevant national and local regulations before disposal. It is recommended to treat with incineration. The sulfur oxides discharged from the incinerator are removed by a scrubber.
