Vapor or mist can cause conjunctivitis, conjunctival edema, corneal opacity, and even blindness. ； Inhaling sulfuric acid mist can cause respiratory tract irritation, and in severe cases, dyspnea and pulmonary edema. ； High concentrations can cause laryngospasm or glottis edema, resulting in suffocation and death. After taking the product, it can cause digestive tract fever and even ulcer formation. ； Severe cases may include gastric perforation, peritonitis, kidney damage, shock, etc. Skin exposure to sulfuric acid may cause erythema in mild cases and ulcers in severe cases. After healing, the scars may shrink and affect function. Sulfuric acid splashed into the eyes can cause burns, even corneal perforation, panphthalmia and even blindness. Long-term exposure to sulfuric acid mist can cause nasal mucosa atrophy. Loss of the sense of smell, tooth erosion, sleepy bronchitis, pulmonary edema and cirrhosis of the liver. environmental hazards: Harmful to the environment. Special attention should be paid to pollution of water bodies. Fire and explosion hazard: Contact with combustion aids in this product may cause combustion. 　　　　　　　　　　　　　Part 4 First aid measures Skin contact: Take off contaminated clothing immediately, rinse with plenty of running water for at least 15 minutes, and seek medical attention. eye contact: Lift your eyelids immediately, rinse thoroughly with plenty of running water or saline for 15 minutes, and seek medical attention. inhalation: Leave the scene quickly to a place with fresh air and keep the respiratory tract open. If it is difficult to breathe, give oxygen. If the respiratory tract stops, perform artificial respiration and seek medical treatment immediately. ingest: Rinse mouth with water, give milk or egg white to drink, and seek medical advice. 　　　　　　　　　　　　　Part 5: Hazardous Characteristics of Fire Fighting Measures: It supports combustion, releases heat when exposed to water, and can cause boiling and splashing. Contact with flammable materials (such as benzene) and combustible materials (such as sugar, fiber, etc.) will cause violent reactions and even cause combustion. In case of calcium carbide, perchlorate, fulminate, nitrate. Picric acid salts, metal powders, etc. react violently, explode or burn, and cause strong corrosion and water absorption. Hazardous combustion products: Sulfur oxide fire extinguishing methods and fire extinguishing agents: Firefighters must wear full-body sulfur and alkali-resistant firefighting suits. fire extinguishing agent: Dry powder, carbon dioxide, sand. Precautions for fire extinguishing: Avoid water hitting objects, as water will release a lot of heat and cause splashing and burns. 　　　　　　　　　　　　　Part 6 Emergency Response to Leakage Emergency Response: Quickly evacuate personnel from the leaked contaminated area to a safe area, isolate them, and strictly restrict access. It is recommended that emergency responders wear self-contained positive-pressure respirators and acid-alkali protective overalls and avoid direct contact with the leaked material. Cut off the source of leakage as much as possible to prevent small leakage from entering sewers, flood ditches and other restricted spaces.: Mix it with sand, dry lime or soda ash, or wash it with a large amount of water. The washing water is diluted and put into the wastewater system. massive leaks: Build an embankment or dig a pit to contain it, use a pump to transfer it to a tanker or a special collector, and recycle or transport it to a poison treatment site for disposal. Elimination method: If it occurs, use earthen cofferdams or dig pits to prevent the pollution area from expanding, and then use alkaline substances (quick lime or carbide slag, etc.) to neutralize the leaked liquid, or use tap water to flush the leaked liquid in large quantities to dilute it (fire should be strictly prohibited during the dilution process). During treatment, on-site handlers should wear protective equipment to prevent burns. 　　　　　　　　　　　Part 7 Handling and Storage Precautions: Close the operation, pay attention to ventilation, and make the operation as mechanized and automated as possible. Operators must receive special training and strictly abide by operating procedures. When they may be exposed to smoke, they must wear self-priming filter gas masks (full face masks), rubber acid and alkali-resistant clothing, acid and alkali-resistant gloves, and stay away from fire and heat sources. Smoking is strictly prohibited in the workplace. Keep away from flammable and combustible materials. Prevent steam from leaking into the workplace air. Avoid use with reducing agents. Contact with alkalis and alkali metals. When handling, load and unload gently to prevent damage to bags and containers. Equipped with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may contain harmful substances. When diluting or preparing solutions, acid should be added to water to avoid boiling and splashing. Storage precautions: Store in a cool, dry and ventilated warehouse. The storage temperature should not exceed 35°C, and the relative humidity should not exceed 85%. Keep the container sealed and store it separately from flammable materials, combustible materials, reducing agents, alkali metals, and edible chemicals. Avoid mixed storage. The storage area should be equipped with emergency leak treatment equipment and suitable containment materials. 　　　　　　　　　　　　　Part 8 Exposure Control/Personal Protection Maximum Allowable Concentration: China MAC (mg/m3):2 Former Soviet Union: MAC(mg/m3): 1 Monitoring method: Barium chloride is more turbid than turbidity. engineering controls: Close the operation, pay attention to the wind, and be mechanized and automated as much as possible.
