Novel coronavirus pneumonia is caused by a novel coronavirus that is sensitive to chlorine and strong oxidant disinfectants. 84 disinfectant is used in this range and is often used to disinfect homes and medical settings. 84 disinfectant can kill coronavirus, but it can irritate the skin, cause discoloration of fabrics, and the irritating odor may cause respiratory distress. It is important to note that 84 disinfectant must be used in a strict ratio, not too concentrated, within the applicable ratio. When using 84 disinfectant, try to wear a mask, or as far as possible, do not breathe deeply in the environment with 84 disinfectant to prevent damage to the respiratory tract.
