How to use quick-drying hand disinfectant

As living conditions improve, more people begin to pay attention to personal hygiene and safety. From the previous disinfectants to hand sanitizers, to the no-rinse hand sanitizers in "Where Are We Going, Dad", to the current quick-drying hand sanitizers, all of them demonstrate the progress of technology. The focus of this article is on quick-drying hand sanitizer, a disinfectant with ethanol as its main ingredient. It is a special hand cleaning product, it is healthy for the skin, non-irritating and has no added fragrance. A must-have for families with children and pets.

Properties and stability: Dark purple slender rhombic columnar crystals with blue metallic luster. The taste is sweet and astringent. Density 2.703 g/cm3. It decomposes at temperatures above 240°C and is easily soluble in water, methanol, and acetone. However, it will burn or explode violently when mixed with organic or volatile substances such as glycerol, sucrose, camphor, turpentine, ethylene glycol, ether, and hydroxylamine. The aqueous solution is unstable. It decomposes when exposed to light, generating gray-black manganese dioxide precipitate that adheres to the container.

Skin contact : Take off contaminated clothes immediately and rinse with plenty of running water for at least 15 minutes. Seek medical attention.

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

Inhalation: Move quickly away from the scene to fresh air. Keep the airways open. If breathing is difficult, give oxygen. If breathing stops, perform artificial respiration immediately. Seek medical attention.

Ingestion : Rinse mouth with water and give milk or egg white. Seek medical attention.

Hazardous properties : Strong oxidizing agent. It can explode when exposed to sulfuric acid, ammonium salts or hydrogen peroxide. It can cause spontaneous combustion when in contact with glycerin or ethanol. There is a risk of combustion and explosion when it comes into contact or mixes with organic matter, reducing agents, and flammable substances such as sulfur and phosphorus.

Hazardous combustion products: potassium oxide, manganese oxide.

Fire extinguishing method: Use water, mist water, sand and soil to extinguish fire.

Emergency treatment: Isolate the leaked contaminated area and restrict entry and exit. It is recommended that emergency response personnel wear dust masks (full-face masks) and protective clothing. Avoid direct contact with leaking material. Small spills: Mix with sand, dry lime or soda ash. Collect with a clean shovel into a dry, clean, covered container. Large leakage: Collect for recycling or transport to a waste disposal site for disposal.

Notes for operation : Operate in a closed environment with enhanced ventilation. Operators must undergo special training and strictly abide by operating procedures and stay away from fire and heat sources. Smoking, eating and drinking are strictly prohibited in the workplace. Avoid generating dust. Avoid contact with reducing agents and active metal powders. Be careful when handling to prevent damage to the packaging and containers. Equipped with appropriate types and quantities of fire-fighting equipment and leakage emergency treatment equipment. Empty containers may contain hazardous residues.

Storage precautions : Store in a cool, ventilated warehouse. Keep away from fire and heat sources. The warehouse temperature shall not exceed 32°C and the relative humidity shall not exceed 80%. The package is sealed. It should be stored separately from reducing agents, active metal powders, etc. and should not be mixed. The storage area should be equipped with suitable materials to contain leaks.

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

Eye protection : Protection is already provided in respiratory protection.

Body protection : Wear adhesive tape anti-toxic clothing.

Hand protection : Wear neoprene gloves.

Other protection : After work, take a shower and change clothes. Maintain good hygiene habits.

Prohibited materials: strong reducing agents, active metal powders, sulfur, aluminum, zinc, copper and their alloys, flammable or combustible materials.

Drug action : This product is used as a disinfectant, deodorant, and water purifier. Potassium permanganate is a strong oxidant. When it comes into contact with organic matter, it releases new oxygen and kills bacteria. It has a very strong bactericidal ability, but it is easily weakened by organic matter, so the effect is superficial and not lasting. It can deodorize and disinfect, and is used for sterilization and disinfection, and has an astringent effect. While potassium permanganate is oxidizing, it is also reduced to form manganese dioxide, which combines with protein to form a protein salt complex. Both this complex and permanganese ions have astringent effects. It is also used as an oxidant in the analysis of certain metal ions. It is also used as a bleaching agent, toxic gas absorbent, carbon dioxide refining agent, etc.
