Hazard Overview

Health hazards: Its vapor has a stimulating effect, causing eye and upper respiratory tract irritation symptoms such as tearing, throat irritation, coughing, accompanied by headaches, dizziness, chest tightness, etc. Oral administration can cause severe abdominal pain, and in severe cases, there may be gastric perforation, peritonitis, laryngeal spasm, kidney damage, shock, and asphyxia. Skin contact can cause burns. Chronic effects: Long term exposure can cause dental erosion

Environmental hazards: Harmful to the environment, can cause pollution to water bodies and soil

Explosive hazard: This product supports combustion, has strong corrosiveness and irritation, 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. It can react violently with various substances such as metal powder, calcium carbide, hydrogen sulfide, turpentine, and even explode. Contact with reducing agents, combustibles such as sugar, cellulose, sawdust, cotton, straw, or waste yarn can cause combustion and release highly toxic brown smoke. Has strong corrosiveness

Firefighting method: Firefighters must wear full body acid and alkali resistant firefighting suits. Fire extinguishing agents: misty water, carbon dioxide, sand

Emergency response to leakage

Quickly evacuate personnel from the contaminated area to a safe zone, isolate them, and strictly restrict their entry and exit. It is recommended that emergency personnel wear self-contained positive pressure respirators and acid and alkali resistant work clothes. Enter the site from the upwind direction. Cut off the leakage source as much as possible. Prevent the flow into restricted spaces such as sewers and drainage ditches. Minor leakage: Sprinkle soda ash on the ground, then rinse with a large amount of water, dilute the washing water, and put it into the wastewater system. Massive leakage: Construct embankments or dig pits to contain it. Spray like water cools and dilutes steam, protects on-site personnel, and dilutes leakage into incombustible materials. Transfer to a tanker or dedicated collector using a pump, recycle or transport to a waste disposal site for disposal

Handling and Storage

Precautions for operation: Closed operation, pay attention to ventilation. Operate as mechanically and automatically as possible. Operators must undergo specialized training and strictly adhere to operating procedures. It is recommended that operators wear self-priming filter type gas masks (full face masks), rubber acid and alkali resistant clothing, and rubber acid and alkali resistant gloves. Keep away from sources of fire and heat, and smoking is strictly prohibited in the workplace. Prevent steam leakage into the workplace air. Avoid contact with reducing agents, bases, alcohols, and alkali metals. 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. When diluting or preparing a solution, acid should be added to water to avoid boiling and splashing

Storage precautions: Store in a cool and ventilated warehouse. Stay away from sources of fire and heat. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from reducing agents, alkalis, alcohols, alkali metals, etc., and mixed storage should be avoided. The storage area should be equipped with emergency response equipment for leaks and suitable containment materials

Contact control and individual protection

Engineering control: Closed operation, pay attention to ventilation. Mechanize and automate as much as possible. Provide safety shower and eye wash equipment

Respiratory protection: When there is a possibility of exposure to its smoke, wear a self-priming filter type gas mask (full face mask) or air respirator. It is recommended to wear an oxygen respirator during emergency rescue or evacuation

Eye protection: respiratory system protection has been taken. Body protection: wear rubber acid and alkali resistant clothing. Hand protection: wear rubber acid and alkali resistant gloves

Other protections: Smoking, eating, and drinking are prohibited at the work site. After work, take a shower and change clothes. Store clothes contaminated with toxic substances separately and wash them for later use. Maintain good hygiene habits
