edit
1. Electronic industry is used for coating cathode, and agriculture is used as quick acting fertilizer for acid soil and plant quick calcium supplement agent.
2. Used as analytical reagent and fireworks material.
3. It is the raw material for manufacturing other nitrates.
4. Agricultural calcium nitrate is a typical fast acting foliar fertilizer, which can act more smoothly on acidic soil. The calcium in the fertilizer can neutralize the acidity in the soil.It is particularly convenient for the regenerative fertilization of winter crops, the post (qualitative) additional fertilization of grains, the growth fertilization of alfalfa that consumes too much, the sugar beet, feed beet, poppy, corn, green feed mixture, and the additional fertilization that effectively eliminates calcium deficiency in plants.
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.Do not touch the leakage directly.Do not allow the leakage to come into contact with reducing agent, organic matter, inflammables or metal powder.
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: covered with plastic cloth and canvas.Then collect and recycle or transport to waste disposal site for disposal.
First aid measures

edit
Skin contact: Take off contaminated clothes and wash with plenty of flowing 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.
Protective measures

Precautions for operation: close operation and strengthen ventilation.Operators must be specially trained and strictly abide by the operating procedures.It is recommended that operators wear self-priming filter type dust masks, safety goggles, polyethylene gas suits and neoprene gloves.Keep away from kindling and heat sources, and smoking is strictly prohibited in the workplace.Avoid dust generation.Avoid contact with reducing agents and acids.Load and unload gently during transportation to prevent damage to packaging and containers.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 warehouse temperature should not exceed 26 ℃.Keep container sealed.It shall be stored separately from oxidant, reducing agent and alkali, and mixed storage is strictly prohibited.Explosion proof lighting and ventilation facilities shall be adopted.It is prohibited to use mechanical equipment and tools that are easy to generate sparks.The storage area shall be equipped with leakage emergency treatment equipment and appropriate materials.
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.
