First aid measures
Announce
edit
Skin contact: Take off the contaminated clothes and wash the skin thoroughly with soapy water and clean water.
Eye contact: Lift the eyelid and flush with flowing water or physiological saline.Get medical attention.
Inhalation: quickly leave the site to a place with fresh air.Keep the respiratory tract unobstructed.If breathing is difficult, give oxygen.If breathing stops, perform artificial respiration immediately.Get medical attention.
Ingestion: drink enough warm water to induce vomiting.Get medical attention.
Fire fighting measures
Announce
edit
Hazard characteristics: inorganic oxidant.In case of combustible fire, it can promote the fire.The mixture with combustibles is easy to catch fire and will burn violently.It decomposes at high temperature, releasing extremely toxic nitrogen oxide gas (more toxic than polonium).
Hazardous combustion products: nitrogen oxides.
Extinguishing method: firefighters must wear filter type gas masks (full face masks) or isolated respirators, wear full body fire and gas clothing, and extinguish the fire upwind.Do not spray water directly onto molten materials to avoid serious flowing fire or severe boiling splash.
Extinguishing agent: fog water, sand.
Leakage emergency treatment
Announce
edit
Isolate the leakage contaminated area and restrict access.It is recommended that emergency personnel wear dust masks (full face masks) and gas suits.
Small amount of leakage: wash with a large amount of water, and put the diluted washing water into the waste water system.
Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.
Protective measures

edit
Engineering control: closed operation, local exhaust.
Respiratory protection: When the concentration in the air is high, you should wear a self-priming filter type dust mask.If necessary, it is recommended to wear self-contained breathing apparatus.
Eye protection: wear chemical safety goggles.
Body protection: wear adhesive tape anti-virus clothing.
Hand protection: wear rubber gloves.
Other protection: keep good hygiene habits.Pre employment and regular physical examination shall be carried out.
Operation, disposal, storage and transportation
Announce
edit
Operation precautions: closed operation, local exhaust.Operators must be specially trained and strictly abide by the operating procedures.It is recommended that operators wear self-priming filter type dust mask, chemical safety goggles, rubber cloth gas suit and rubber gloves.Keep away from kindling and heat sources, and smoking is strictly prohibited in the workplace.Keep away from flammable and combustible materials.Avoid dust generation.Avoid contact with reducing agent.Load and unload with care during transportation to keep the package intact and prevent leakage.Fire fighting equipment and leakage emergency treatment equipment of corresponding types and quantities shall be provided.Empty containers may leave harmful substances.
Precautions for storage: store in a cool and ventilated warehouse.Keep away from kindling and heat sources.The package must be completely sealed to prevent moisture absorption.It shall be stored separately from combustibles, reducing agents and edible chemicals, and mixed storage is strictly prohibited.The storage area shall be equipped with appropriate materials to contain leakage.
Packaging method: threaded glass bottle, iron cap pressed glass bottle, plastic bottle or ordinary wooden case outside metal bucket (can);The threaded glass bottle, plastic bottle or tinned sheet steel barrel (can) is covered with a full floor lattice box, fiberboard box or plywood box.
Precautions for transportation: during railway transportation, the dangerous goods shall be loaded in strict accordance with the dangerous goods loading table in the Dangerous Goods Transportation Rules of the Ministry of Railways.It shall be transported separately, and the container shall not leak, collapse, fall or be damaged during transportation.The transport vehicles shall be equipped with corresponding types and quantities of fire-fighting equipment.It is strictly prohibited to transport together with acids, inflammables, organics, reducing agents, spontaneous combustion materials, inflammables in wet conditions, etc.During transportation, the speed should not be too fast, and forced overtaking is not allowed.Transport vehicles shall be thoroughly cleaned before and after loading and unloading. It is strictly prohibited to mix with organic substances, combustibles and other impurities.
