Isopropyl Alcohol (IPA) is an important C3 aliphatic unit alcohol. It is an important solvent and raw material for organic synthesis. IPA is directly used as a solvent, which can be used alone or mixed with other solvents for inks, coatings, color printing, electronic cleaning, etc; IPA is used as organic synthetic raw material for the synthesis of acetone, methyl isobutyl ketone, isopropylamine, isopropyl ester, isopropyl ether, etc; IPA is used as raw material and solvent in pharmaceutical, pesticide and other industries, and in the production of chloramphenicol, fungicide, herbicide, etc; In daily chemicals, IPA can be used as detergent, disinfectant, glass cleaner, cosmetics and other sanitary products; In the water treatment industry, IPA is used as hard water treatment agent and descaling agent; In the rubber industry, IPA is used as vulcanization accelerator; IPA can also be used to manufacture surfactants, textile auxiliaries, solubilizers, detergents, depilants, etc.

Part II: Composition / composition information
Content of harmful substances casno
Part III: hazard overview
Health hazards: headache, drowsiness, ataxia and eye, nose and throat irritation after exposure to high concentration steam. Oral administration can cause nausea, vomiting, abdominal pain, diarrhea, sleepiness, coma and even death. Long term skin contact can cause dry and chapped skin.
Explosion hazard: This product is flammable and irritating.
Part IV: first aid measures
Skin contact: take off contaminated clothes and wash skin thoroughly with soapy water and clear water.
Eye contact: lift the eyelids and rinse with flowing water or normal saline. See a doctor.
Inhalation: quickly leave the site to a place with fresh air. Keep the respiratory tract unobstructed. If breathing is difficult, give oxygen. If breathing stops, give artificial respiration immediately. See a doctor.
Ingestion: drink enough warm water to induce vomiting. Gastric lavage. See a doctor.
Part V: fire fighting measures
Hazard characteristics: flammable, its vapor and air can form an explosive mixture, which can cause combustion and explosion in case of open fire and high heat. Contact with oxidant and react violently. In the fire scene, heated containers are in danger of explosion. Its vapor is heavier than air, and can spread to a considerable distance at a lower place. It will catch fire and burn back when encountering a fire source.
Harmful combustion products: carbon monoxide, carbon dioxide.
Fire extinguishing method: move the container from the fire site to an open place as far as possible. Spray water to keep the containers at the fire site cool until the end of fire fighting. If the container in the fire site has changed color or generated sound from the safety pressure relief device, it must be evacuated immediately. Extinguishing agent: insoluble foam, dry powder, carbon dioxide, sand.
Part VI: emergency treatment of leakage
Emergency treatment: evacuate the personnel in the leakage contaminated area to the safety area quickly, isolate them and strictly restrict their access. Cut off the fire source. It is recommended that emergency treatment personnel wear self-contained positive pressure respirators and anti-static work clothes. Cut off the leakage source as much as possible. Prevent it from flowing into restricted spaces such as sewers and flood drainage ditches. Small leakage: absorb or absorb with sand or other non combustible materials. It can also be washed with a large amount of water, which is diluted and then put into the wastewater system. Massive leakage: build a dike or dig a pit for storage. Cover with foam to reduce steam disaster. Use explosion-proof pump to transfer to tank car or special collector, recycle or transport to waste disposal site for disposal.
Part VII: handling and storage
Precautions for operation: closed operation, full ventilation. Operators must receive special training and strictly abide by the operating procedures. It is recommended that operators wear filter gas masks (half masks), safety glasses, anti-static work clothes and latex gloves. Keep away from kindling and heat sources. Smoking is strictly prohibited in the workplace. Use explosion-proof ventilation system and equipment. Prevent steam from leaking into the air of the workplace. Avoid contact with oxidants, acids and halogens. During filling, the flow rate should be controlled and there should be a grounding device to prevent the accumulation of static electricity. Handle with care to prevent package and container damage. Equip with corresponding varieties and quantities of fire-fighting equipment and leakage emergency treatment equipment. Emptied containers may leave harmful substances.
Storage precautions: store in a cool and ventilated warehouse. Keep away from kindling and heat sources. The storage temperature should not exceed 30 ℃. Keep the container sealed. It should be stored separately from oxidants, acids, halogens, etc., and should not be mixed. Explosion proof lighting and ventilation facilities are adopted. It is forbidden to use mechanical equipment and tools that are easy to produce sparks. The storage area shall be equipped with leakage emergency treatment equipment and suitable storage materials.
Part VIII: exposure control / personal protection
Occupational exposure limit
China MAC (mg/m3):200
MAC of the former Soviet Union (mg/m3):10
Engineering control: the production process is closed and fully ventilated. Provide safety shower and eye wash equipment.
Respiratory protection: generally, special protection is not required. Filter gas masks (half masks) can be worn when exposed to high concentrations.
Eye protection: generally, special protection is not required, and safety glasses can be worn in case of high concentration contact.
Body protection: wear anti-static work clothes.
Hand protection: wear latex gloves.
Other protection: smoking is strictly prohibited at the work site. Keep good hygiene habits.
