Lithium perchlorate is an inorganic compound with the chemical formula LiClOfourIt belongs to perchlorate and is a colorless or white crystalline powder with high solubility and is easy to dissolve in a variety of solvents.Lithium perchlorate can be used as an oxygen source. It starts to decompose at about 400 ℃ and immediately decomposes at 430 ℃ to produce lithium chloride and oxygen.Lithium perchlorate is a perchlorate with the highest oxygen mass fraction and volume fraction except expensive and highly toxic beryllium perchlorate. Because of its high oxygen content, it is used in the aerospace field.
Listed in the List of Explosive Hazardous Chemicals[2]，It shall be controlled in accordance with the Public Security Management Measures for Explosive Hazardous Chemicals[3]。
It starts to decompose at about 400 ℃, and decomposes immediately at 430 ℃ to generate lithium chloride and oxygen.It can form explosive mixture when mixed with reducing agent, organic matter, flammable substances such as sulfur, phosphorus or metal powder.

First aid measures
Announce
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.[1]
Fire extinguishing method: use fog water and sand to extinguish the fire.[1]
Emergency Management
Announce
edit
Emergency treatment: 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 allow the leakage to contact with organics, reducing agents and inflammables.
Small amount of leakage: cover it with dry lime and soda ash and collect it in a closed container.A large amount of water can also be used for flushing, and the diluted washing water will be discharged into the waste water system.
Large amount of leakage: collect and recycle or transport to waste disposal site for disposal.[1]

Precautions for operation: closed operation, full ventilation.Operators must be specially trained and strictly abide by the operating procedures.It is recommended that operators wear hood type electric air supply filter type dust respirator, polyethylene 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 active metal powder.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 package must be sealed to prevent moisture.It shall be stored separately from combustible (combustible) materials, active metal powder, etc., and mixed storage is strictly prohibited.The storage area shall be equipped with appropriate materials to contain leakage.[1]
