Hazard Overview

Health hazards: Strong irritant and corrosive effects on tissues such as skin and mucous membranes. Steam or mist can cause conjunctivitis, conjunctival edema, corneal opacity, and even blindness; Causing respiratory irritation, and in severe cases, respiratory distress and pulmonary edema; High concentration causes laryngeal spasm or glottal edema, leading to suffocation and death. Oral administration can cause gastrointestinal burns and ulcer formation; Severe cases may include gastric perforation, peritonitis, kidney damage, shock, etc. Mild skin burns can cause redness, while severe burns can lead to ulceration. After recovery, the scar contraction can affect function. Splashing into the eyes can cause burns, even corneal perforation, panoculitis, and even blindness. Chronic effects: dental erosion, chronic bronchitis, emphysema, and pulmonary sclerosis

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

Fire protection measures

Dangerous characteristics: When in contact with water, it releases a large amount of heat and may cause boiling and splashing. Contact with flammable materials (such as benzene) and combustible materials (such as sugar, cellulose, etc.) can cause violent reactions and even lead to combustion. Explosion or combustion may occur when encountering violent reactions such as calcium carbide, perchlorate, fulminate, nitrate, picrate, metal powder, etc. Has strong corrosiveness and water absorption

Harmful combustion products: sulfur dioxide

Firefighting method: Firefighters must wear full body acid and alkali resistant firefighting suits. Fire extinguishing agents: dry powder, carbon dioxide, sand. Avoid water flow impacting objects to prevent the release of a large amount of heat when in contact with water, which can cause splashing and burn the skin

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. Do not come into direct contact with the leaked material. Cut off the leakage source as much as possible. Prevent the flow into restricted spaces such as sewers and drainage ditches. Minor leakage: Mix sand, dry lime, or soda ash. You can also 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. 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. Keep away from flammable and combustible materials. Prevent steam leakage into the workplace air. Avoid contact with reducing agents, alkalis, 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. The storage temperature shall not exceed 35 ℃, and the relative humidity shall not exceed 85%. Keep the container sealed. It should be stored separately from flammable materials, reducing agents, alkalis, alkali metals, and edible chemicals, and avoid mixing storage. 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: Protective measures have been taken in respiratory system protection

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
