Part 3, Hazard Identification Information

Hazard Summary Oxides can easily catch fire when in contact with combustibles. Harmful or may have serious consequences if swallowed. Serious irritation or burns to eyes and respiratory tract. Irritating to skin. No significant harm to the environment.

Potential health hazards Skin contact: Slightly irritating and can easily cause skin ulcers and burns. Eye contact: It is irritating to the eyes and can easily cause eye pain, redness and other uncomfortable symptoms. Inhalation: It is irritating to the respiratory tract and can easily cause symptoms such as coughing, sneezing, sore throat and difficulty breathing. Ingestion: May cause vomiting and diarrhea.

Part 4 First Aid Measures

Skin contact... Take off contaminated clothing and rinse with plenty of running water.

Eye contact... Lift your eyelids, rinse with running water or saline, and seek medical attention.

Inhalation……………………Quickly leave the scene and go to fresh air. Keep your airway open. If breathing is difficult, give oxygen.

If breathing stops, perform artificial respiration immediately and seek medical attention.

Ingestion……………………Drink plenty of warm water, seek medical attention, and do not induce vomiting.

Part 5: Fire-fighting measures -

Hazardous characteristics: Strong oxidant, highly corrosive. It decomposes when heated to produce oxygen, which intensifies the combustion of flammable materials. It gradually decomposes when exposed to moisture, and may cause a fire or explosion when in contact with or mixed with organic matter, reducing agents, and flammable substances such as sulfur and phosphorus.

Decomposition in closed containers or spaces may cause explosion hazard.

Fire-fighting methods Evacuate all irrelevant personnel immediately. Wear protective equipment and self-contained breathing apparatus. Keep air flowing to eliminate toxic gases and decomposition products. Spray with large amounts of water

Part Six: Emergency Response to Spills - Isolate the leaked contaminated area and evacuate all irrelevant personnel. It is recommended that emergency responders wear self-contained breathing apparatus and disinfectant clothing. Do not come into direct contact with leaked material. Do not let the leaked material come into contact with organic matter, reducing agents, and flammable substances. Small leakage: Use a clean shovel to collect and place in a dry, clean, covered container. Large leakage: collect and recycle or transport

to a waste disposal site for treatment. Flush the leaked contaminated area with plenty of water.

Part 7: Handling and Storage -

Storage Precautions Oxidizer! Store in a dry, clean and well-ventilated warehouse. Keep away from fire, heat and direct sunlight.

The room temperature is below 40°C and the relative humidity is kept below 75. Pay attention to moisture and rain. Keep containers tightly sealed and labels intact. When handling, load and unload with care to prevent damage to packaging and containers, and pay attention to maintaining normal pressure relief in containers. It is not suitable to transport on rainy days. It should be stored separately from flammable or combustible materials, reducing agents, sulfur, phosphorus, etc., and mixed storage and transportation should be avoided. Avoid contact with other substances that may easily cause product decomposition.

Precautions for use: Avoid contact with eyes, skin and clothing. Keep the surrounding air flowing during operation. Do not swallow or inhale dust, mist or gas. Do not eat, drink or smoke in the working environment. Avoid contact with flammable and organic matter.

Containers should be labeled and kept sealed when not in use. Wash hands and other body contact parts after handling.

Part 8: Exposure Controls/Personal Protection -

Engineering Controls

Keep indoor air flowing and equipped with air circulation devices. Avoid dust and aerosol, and do not operate in a closed space. Observe frequently to determine the exposure hazard value, and keep the exposure hazard value below the protection standard value.

Respiratory system protection

Normally no special protection is required, but when the working environment is uncertain or dusty, or the environmental hazard level exceeds the upper limit

, air respirators, self-contained breathing apparatus, oxygen respirators, filter gas masks (half and full face masks), dust masks and other protective equipment should be used.

Face/eye protection

Sodium percarbonate applications

Sodium percarbonate particles

Sodium percarbonate can be used to produce H2O2: Hydrogen peroxide (H2O2), commonly known as hydrogen peroxide, is a colorless liquid at room temperature. It is difficult to ionize and easy to decompose. As a classic chemical product, industrial production began more than a hundred years ago. With the growth of social needs, especially the need for ecological environmental protection, hydrogen peroxide has become more popular in recent years and is known as the "green oxidant". For the convenience of storage, transportation and use, alcohol precipitation is used in industry to convert it into solid sodium percarbonate crystals (chemical formula: 2Na2CO3?3H2O2). This crystal has the duality of Na2CO3 and H2O2. The production process of alcohol precipitation is as follows: at 0 to 5°C, add H2O2 and stabilizers (MgCl2 and Na2SiO3) to the saturated Na2CO3 solution. After full reaction, add isopropyl alcohol, filter and separate the liquids, that is Obtain sodium carbonate crystals.
