WASHINGTON August 23, 2015 Reuters (Epoch Times reporter Li Dexin compile reports), a new survey of industrial Washington State Department of Labor (Department of Labor and Industries) found for car wash and truck wash detergents may harmful to the human body.

According to the spokesman (spokesman) website reported, a report US Centers for Disease Control and Prevention on Friday (August 21) released data show, a study by the Washington State Department of Labor found that industry led to do, during the 2001 to 2013 Washington region has 48 workers in the use of hydrofluoric acid-based washing liquid after burns, apply for workers' compensation and therefore, where there is a 38-year-old man due to the inhalation of some washing solution containing hydrofluoric acid and death, yet now unclear whether he was deliberately taking the washing liquid.

HF (Hydrofluoric acid, HF) is a common washing agent, mainly used in automotive lighting and cleaning the car the contaminated dirt road. The study found that injured workers is mainly due to forget to wear gloves or gloves with holes caused by the hand, head or eye burns, including seven workers were rushed to hospital, three workers suffered third-degree burns, 2 Workers must do surgery including skin grafts, including.

One example cited in the report is that a worker in the washing solution containing hydrofluoric acid was poured into another container from a container, the washing liquid spilled on his own pants leg, when he did not realize it seriousness, he continued to work for 90 minutes, and then he contacted the washing liquid skin burning sensation began to appear, he found his pants and shoes were thoroughly soaked in the washing liquid. The ambulance workers were sent to a burn unit, but then he has appeared in third-degree burns, so do skin grafting. Although he is now healed, but his left-footed chronic numbness, so he applied for and received a permanent partial disability compensation.

Researchers in this investigation Huaitakeer (Carolyn Whitaker) believes that when the car wash using a low concentration of hydrofluoric acid, hydrofluoric acid, a little pain or no pain after contact with skin, therefore use its workers often do not realize that they have been burns, when to seek medical attention until they had held up the best time for treatment.

She said commercial car wash or truck field should not contain hydrofluoric acid cleaning alternatives, but for really using hydrofluoric acid workplace, they should ensure that workers are well aware of serious harm to humans caused by hydrofluoric acid, and is configured for workers gloves and other protective equipment.

Hydrofluoric acid application is quite wide, manufacture washing from freezing, corrosion, glass polishing, ceramics to marble, chemical fertilizers, pesticides, dyes, plastics, solvents, condensing agents and high octane petroleum feedstocks can be reflected trail. Other manufacturing industries such as semiconductors, microelectronics circuits, quartz crystal manufacturing is also an important application. Such as rust agents, brighteners and detergents may have their ingredients in the family.

After accidental contact with hydrofluoric acid damage include: hydrofluoric acid hydrogen ions (H +) will burn the skin, causing skin degeneration and corrosion. In addition, hydrofluoric acid fluoride ion (F-) is quite toxic ions, can cause soft tissue necrosis liquefaction, and then to the inner part of the bones, causing corrosion and to calcification. In case via skin contact, inhalation or inadvertent ingestion of fluoride ions also affect other body systems such as cardiopulmonary gastrointestinal and nervous systems.

Clinical characterization of hydrofluoric acid damage to its route of exposure, concentration of hydrofluoric acid, the length of time of contact, or contact with the tissue penetration resistance related.
