Sodium peroxide, ainorganic compound, chemical formula is NatwoOtwo, yellow white powder or particle[7]。It decomposes when heated to 460 ℃.Absorbs moisture and carbon dioxide quickly in the air.Contact with organic matter will lead to combustion or explosion, so it should be kept in a closed place.It is used to bleach animal and plant fibers, feathers, animal bones, etc., as a printing and dyeing agent for fabrics, an absorbent of carbon dioxide in the air, an air exchange agent in submarines, chemical reagents, oxidants and analytical reagents.[1]
Listed in the List of Explosive Hazardous Chemicals[4]，It shall be controlled in accordance with the Public Security Management Measures for Explosive Hazardous Chemicals[5]。
2. Sodium peroxide can react with water to produce sodium hydroxide and hydrogen peroxide
Hydrogen peroxide will be decomposed into water and oxygen

Environmental hazards
It is slightly harmful to water.Do not allow undiluted or large quantities of products to come into contact with groundwater, waterways or sewage systems. Do not discharge materials into the surrounding environment without government permission.
The dust of this product irritates eyes and respiratory tract, and corrodes nasal septum;Direct skin contact may cause burns;If taken by mistake, it may cause burns to the digestive tract.[3]
This product is combustion supporting, corrosive, irritant to the respiratory system and skin, and can cause burns to the human body.[3]
Hazard prevention
Skin contact: Take off contaminated clothes immediately, wash with plenty of flowing water for at least 15 minutes, and seek medical advice.[3]
Eye contact: immediately lift the eyelids, thoroughly flush with a large amount of flowing water or physiological saline for at least 15 minutes, and then seek medical advice.[3]
Inhalation: quickly leave the site to a place with fresh air to keep the respiratory tract unobstructed. If breathing is difficult, give oxygen.If breathing stops, perform artificial respiration immediately.Get medical attention.[3]
Ingestion: Rinse with water, drink milk or egg white, and seek medical advice.[3]
Extinguishing method: use dry powder and sand to extinguish the fire. Do not use water, foam or carbon dioxide to extinguish the fire.[3]
Emergency Management
Isolate the leakage contaminated area and restrict access. It is recommended that emergency treatment personnel wear dust masks (full face masks) and gas suits. Do not directly contact the leakage, and do not allow the leakage to contact organic substances, reducing agents, and combustibles.Small amount of leakage: mixed with sand, dry lime or soda ash and collected in a closed container.Large amount of leakage: cover with plastic cloth and canvas, then collect and recycle or transport to waste disposal site for disposal.[3]
Storage and transportation

Storage method
It shall be stored in a cool, dry and well ventilated warehouse, away from kindling and heat sources. The warehouse temperature shall not exceed 35 ℃, and the relative temperature shall not exceed 75%. The package shall be sealed.Pay attention to moisture and rain, and store them separately from reducing agents, acids, alcohols, active metal powders, etc. Do not store them together. The storage area should be equipped with appropriate materials to contain leakage.[3]Prohibited substances: strong reducing agent, water, acid, flammable or combustible, alcohol, carbon dioxide, sulfur, active metal powder.[2]Conditions to avoid contact: friction, moist air.[2]
Transport method
For enclosed operation and enhanced ventilation, operators must receive special training and wear labor protection equipment[2]。Strictly abide by the operating procedures. It is recommended that the operators wear head mounted electric air supply filter type dust respirator, polyethylene gas protective clothing, neoprene gloves, and keep away from kindling and heat sources. Smoking is strictly prohibited in the workplace to avoid dust generation, and contact with reducing agents, acids, alcohols, and active metal powders. In particular, they should avoid contact with water. They should be loaded and unloaded lightly when carrying,Protect packaging and containers from damage.Vibration, impact and friction are prohibited, and fire-fighting equipment and leakage emergency treatment equipment of corresponding types and quantities shall be provided.Empty containers may leave harmful substances.[3]
