If you touch it, your fingers will be burned! Don't step into the minefield of "mixing and matching" these cleaning agents during the Spring Festival cleaning

Spring Festival is coming

Many people started cleaning

But be careful

Improper use of cleaning agents

But it will hurt people

recently

A man was careless for a moment.

Three fingers "rotten out of a black hole"

On January 3, Mr. Zhong from Quanzhou, Fujian, was cleaning ceramic flower paper on ceramics. Although he wore two layers of industrial cloth gloves and dipped a cotton swab in hydrofluoric acid, he did not use professional rubber gloves and used a large amount of hydrofluoric acid, which penetrated into the cloth gloves and caused burns to his fingers . Later treatment may have to last one or two months.

Mr. Zhong reminded everyone that they must enhance their safety awareness of hazardous chemicals and should not take chances when working.

Every household may be exposed to it! How dangerous is hydrofluoric acid?

Hydrofluoric acid may sound unfamiliar, but in fact, many people’s home cleaners may contain this ingredient.
Hydrofluoric acid is an aqueous solution of hydrogen fluoride gas. It is colorless, transparent, and has a pungent odor. It is extremely corrosive and can corrode metals, glass, and silicon-containing objects, and can even erode human bones. It can be said to be a terrible "bone-dissolving water."

There have been many cases of burns from hydrofluoric acid before:

■ A man who specialized in exterior wall cleaning was preparing a cleaning agent containing hydrofluoric acid when the base of his left hand accidentally came into contact with the residual cleaning agent in the bottle, causing severe pain. He was later diagnosed with third-degree burns .

■ A 67-year-old man accidentally knocked over a cleaning agent near his feet, resulting in burns on the instep. A week later, the wound was extremely painful, and gray-black necrotic tissue and yellow exudate appeared. It was diagnosed as a third-degree burn .

Doctor's reminder

Many cleaning agents contain strong acids and bases

Take protective measures when using

↓↓↓

Before cleaning, you should wear special gloves to avoid direct contact with cleaning agents;

Wear a mask to prevent cleaning agents from irritating the respiratory tract;

Wear goggles to prevent cleaning agents from splashing into your eyes and causing eye damage.

Don't step into these minefields of "mixing and matching" cleaning agents during the year-end cleaning

The year-end cleaning is coming, and many people have prepared a variety of cleaning agents. However, it should be noted that different cleaning agents have different effects. Don't think that mixing them will be more effective . In serious cases, toxic gases may be produced or even cause burns.

Toilet cleaner + 84 disinfectant = chlorine poisoning

Chlorine is a toxic and highly irritating gas that can cause nausea, vomiting, chest pain and diarrhea. Therefore, do not use 84 disinfectant and toilet cleaner at the same time when cleaning the bathroom.

84 disinfectant + laundry detergent = toxic substances

Mixing laundry detergent and 84 disinfectant will produce a neutralization reaction, reducing the cleaning effect and even producing toxic substances.

Detergent + toilet cleaner = weakened cleaning effect

Dishwashing liquid is an alkaline cleaner, suitable for removing greasy dirt; toilet cleaner contains hydrochloric acid, which is an acidic cleaner and suitable for cleaning alkaline dirt in the bathroom. Mixing the two will produce a neutralization reaction, resulting in a significant reduction in the cleaning effect .

Don't ignore these cleaning details when cleaning

When cleaning, in addition to using detergents correctly, there are some cleaning details that are easy to overlook that require special attention.

Ventilation: Open windows 2-3 times a day, each time for at least 30 minutes, to improve indoor air and protect the health of the respiratory system.

Cleaning of high-frequency contact items: Use 75% concentration of medical alcohol to wipe mobile phones, keys and other items to quickly remove stains and eliminate bacteria.

Clean cleaning tools: Clean rags, mops, etc. in time to effectively prevent bacterial growth and keep the home environment clean.

Personal protection: Wear gloves and masks when cleaning to prevent chemicals from directly contacting the skin and respiratory tract.

Special reminder!

There is no need to disinfect the air at home, just increase ventilation . Do not spray alcohol on large areas of indoor air or on the surface of objects, and do not buy "spray disinfectants" online for air disinfection.

On the one hand, if alcohol is sprayed into the air and encounters a heat source or sparks, it can easily cause a fire or explosion ; on the other hand, the small particles of disinfectant droplets suspended in the air can be easily inhaled by the human body, causing respiratory discomfort .
