Hazard Overview

Health hazards: Inhalation can cause respiratory damage. Splashing into the eyes, stimulating the conjunctiva, and in severe cases, causing burns. Stimulating the skin. Concentrated solutions or crystals are corrosive to the skin. Oral ingestion can corrode the oral cavity and digestive tract, causing a burning sensation, upper abdominal pain, nausea, vomiting, and swelling of the mouth and throat. For those who take large doses orally, the oral mucosa appears brownish black, swollen and ulcerated, with severe abdominal pain, vomiting, bloody stools, shock, and ultimately death from circulatory failure.

Explosive hazard: This product supports combustion, is corrosive and irritating, and can cause burns to the human body.

Emergency measures

Skin contact: Immediately remove contaminated clothing and rinse with plenty of flowing water for at least 15 minutes. Seek medical attention.

Eye contact: Immediately lift the eyelids and thoroughly rinse with plenty of flowing water or saline solution for at least 15 minutes. Seek medical attention.

Inhalation: Quickly leave the scene and move to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, administer oxygen. If breathing stops, immediately perform artificial respiration. Seek medical attention.

Ingestion: Rinse mouth with water and drink milk or egg whites. Seek medical attention.

Fire protection measures

Hazardous characteristics: Strong oxidizing agent. Explosions can occur when exposed to sulfuric acid, ammonium salts, or hydrogen peroxide. Encountering glycerol and ethanol can cause spontaneous combustion. There is a risk of combustion and explosion when in contact or mixed with organic matter, reducing agents, flammable substances such as sulfur and phosphorus.

Harmful combustion products: potassium oxide, manganese oxide.

Fire extinguishing methods: Use water, mist water, and sand to extinguish the fire.

Emergency response to leakage

Isolate the contaminated area and restrict access. It is recommended that emergency responders wear dust masks (full face shields) and gas protective clothing. Do not come into direct contact with the leaked material. Minor leakage: Mix sand, dry lime, or soda ash. Collect with a clean shovel in a dry, clean, and covered container. Massive leakage: Collect and recycle or transport to waste disposal sites for disposal.

Handling and Storage

Precautions for operation: Closed operation, strengthen ventilation. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear a hood type electric air supply filter dust respirator, rubber protective clothing, and chloroprene rubber gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Avoid generating dust. Avoid contact with reducing agents and active metal powders. Handle with care during transportation to prevent damage to packaging and containers. Equip with corresponding types and quantities of fire-fighting equipment and emergency response equipment for leaks. Empty containers may contain residual harmful substances.

Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature shall not exceed 32 ℃, and the relative humidity shall not exceed 80%. Sealed packaging. It should be stored separately from reducing agents, active metal powders, etc., and avoid mixing storage. The storage area should be equipped with suitable materials to contain leaked materials.

Contact control and individual protection

Exposure limit: China MAC (mg/m3) 0.2 [converted to Mn] Former Soviet Union MAC (mg/m3) without established standards

Engineering control: The production process is sealed and ventilation is strengthened. Provide safety shower and eye wash equipment.

Respiratory protection: When there is a possibility of exposure to dust, it is recommended to wear a hood type electric air supply filter dust respirator.

Eye protection: Respiratory protection has been implemented.

Body protection: Wear adhesive protective clothing. 

Hand protection: Wear chloroprene rubber gloves.

Other protections: Smoking, eating, and drinking are prohibited at the work site. After work, take a shower and change clothes. Maintain good hygiene habits.

Transportation information

Packaging method: Whole vehicle transportation: plastic bag or two-layer kraft paper bag with full or medium opening steel drum. Less than truckload transportation: Plastic bags or double-layer kraft paper bags with full or medium openings in steel drums (with a steel plate thickness of 0.5 millimeters and a net weight of no more than 50 kilograms per drum), and wooden crates with transparent cages. Screw mouth glass bottles, iron cap pressed mouth glass bottles, plastic bottles, or ordinary wooden boxes outside metal drums (cans).

Transportation precautions: During railway transportation, the dangerous goods loading table in the "Dangerous Goods Transport Rules" of the Ministry of Railways should be strictly followed for loading. When transported separately, ensure that the container does not leak, collapse, fall, or damage during transportation. Transport vehicles should be equipped with corresponding types and quantities of fire-fighting equipment during transportation. It is strictly prohibited to transport and mix with acids, flammable materials, organic substances, reducing agents, self igniting materials, and flammable materials when wet. During transportation, the speed should not be too fast and overtaking is not allowed by force. Transport vehicles should be thoroughly cleaned and washed before and after loading and unloading, and it is strictly prohibited to mix impurities such as organic matter and flammable materials.
