Incompatibility:	Water, alcohols, strong bases, amines, acids, strong oxidants.
Conditions to avoid contact:	Humid air
Health hazards:	This product is irritating to the respiratory tract, causing rhinitis, pharyngitis, bronchitis, etc. May have eye irritation, causing conjunctival keratitis. Skin contact cause burning, pain, and redness. Blisters can occur for a long time. It has a sensitizing effect on the skin and can cause skin eczema.
Environmental hazard:	Environmental hazard
Explosion hazard:	This product is flammable, toxic, irritating and sensitizing.
Skin contact:	Immediately remove contaminated clothing and wash skin thoroughly with soap and water. Seek medical attention.
Eye contact:	Immediately lift the eyelids and rinse thoroughly with plenty of running water or saline for at least 15 minutes. Seek medical attention.
Inhalation:	Quickly leave the scene to the fresh air. Keep the airway open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.
Ingestion:	Drink plenty of warm water and induce vomiting. Seek medical attention.
Hazardous characteristics:	In case of fire, high heat or contact with oxidants, there is a risk of fire and explosion. Highly heated or in contact with acid can produce highly toxic cyanide gas.
Hazardous combustion products:	Carbon monoxide, nitrogen oxides, hydrogen cyanide, sulfur oxides.
Fire fighting methods:	Use foam, dry powder, carbon dioxide, sand to extinguish the fire. It is forbidden to use acid and alkali fire extinguishing agents. Fire extinguishing with water is not effective, but water can be used to keep the container cool in the fire.
Emergency treatment:	Quickly evacuate personnel from the contaminated area to a safe area, and immediately isolate 150m, strictly restrict access. Cut off the fire. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear anti-virus suits. Do not touch the spill directly. Cut off the source of the leak as much as possible. Prevent entry into restricted spaces such as sewers and flood drains. Small spill: Absorb with activated carbon or other inert materials. It can also be rinsed with a large amount of water, diluted in water and placed in the wastewater system. Large amount of leakage: Construct a dike or digging pit. Cover with foam to reduce steam hazards. Transfer to a tank truck or special collector with a pump, recycle or transport to a waste disposal site for disposal.
Operational notes:	Closed operation to provide adequate local exhaust. The operation is as mechanized and automated as possible. Operators must be specially trained to strictly follow the operating procedures. It is recommended that operators wear self-priming filter gas masks (full face masks), polyethylene protective suits, and rubber and oil resistant gloves. Keep away from fire, heat, and smoking in the workplace. Use explosion-proof ventilation systems and equipment. Prevent vapors from leaking into the workplace air. Avoid contact with oxidants, acids, and alkalis. Lightly load and unload during handling to prevent damage to packaging and containers. Equipped with the corresponding variety and quantity of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may be harmful residues.
Storage notes:	Stored in a cool, dry, well-ventilated warehouse. Keep away from fire and heat. The package is sealed and must not be in contact with air. It should be stored separately from oxidants, acids, alkalis, and food chemicals, and should not be mixed.Explosion-proof lighting and ventilation facilities are used. It is forbidden to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with leakage emergency treatment equipment and suitable containment materials.
Engineering control:	Strictly closed, providing adequate local exhaust. As mechanized and automated as possible. Safety showers and eyewash equipment are provided.
Respiratory protection	Wear self-priming filter respirators (full face mask) when exposed to poison. It is recommended to wear an oxygen breathing apparatus during emergency rescue or evacuation.
Eye protection:	Protected from respiratory protection.
Body protection:	Wear polyethylene anti-virus clothing.
Hand protection:	Wear rubber and oil resistant gloves.
Other protection:	Smoking, eating and drinking are prohibited at the job site. Work is done and thoroughly cleaned. Store clothes contaminated with poisons separately and wash them for later use. The workshop should be equipped with first aid equipment and medicines. Operators should learn to save themselves and save each other.
Acute toxicity:	LD50: 112 mg/kg (rat oral); 88 mg/kg (rabbit percutaneous)
Irritating:	Rabbit percutaneous: 2mg, causing irritation.
Other harmful effects:	This substance is harmful to the environment and special attention should be paid to the pollution of water bodies.
Disposal method:	Refer to national and local regulations before disposal. It is recommended to use incineration. The gas discharged from the incinerator is removed by a scrubber.
