Experts organized by Sichuan health committee talk about disinfection

On February 18, Sichuan health committee organized some experts to interpret the problems of daily disinfection, office and ventilation system in public places. Wang Yantong, a nurse in charge of the infection management department of West China Hospital of Sichuan University, said that it is more important to wash your hands after taking off your coat than to spray alcohol all over your body. However, if you enter or leave a high-risk public place such as the fever clinic of the hospital, you can use the disinfection function of the washing machine to heat and clean after going home, or soak the clothes in the water above 60 ℃ for 30 minutes. "At present, there is no evidence that the virus will infect clothes and shoes, so people should not spray clothes and shoes with alcohol." Wang Yantong also reminded that when alcohol is needed, 75% of the alcohol can just kill the bacteria, and alcohol with too high or too low concentration can affect the disinfection effect. The right way to disinfect small objects with alcohol is to wipe them rather than spray them.

The AIR conditioning must ensure that the fresh air intake and its surrounding environment are clean and that the fresh air is not polluted. The air conditioner with humidification function shall turn off the humidification function. "After work every day, the fresh air and exhaust system will continue to operate for 1 hour to ensure the fresh indoor air. It is recommended to spray, soak or wipe the operating system with chlorine (Bromine) or chlorine dioxide disinfectant (such as 84 disinfectant) for 10 to 30 minutes." Zhu Hongbin reminded that novel coronavirus pneumonia cases should be closed immediately when suspected air pollution and ventilation conditions were not clear.
