Are disinfectant solutions harmful to humans, but using them in the right way will reduce the impact on people. Most disinfectants are strongly oxidizing and corrosive, and if they come into direct contact with human skin or are accidentally ingested, they can cause greater damage to human health. In addition, if a highly concentrated disinfectant solution is used to disinfect the room, it can irritate the respiratory tract and cause bronchitis, pneumonia or pulmonary edema in severe cases. Therefore, when using disinfectant solution, it is recommended to add water or other items to dilute the disinfectant solution to reduce the concentration of the disinfectant solution, and to bring gloves and masks when using it, so as to effectively reduce the harm of the disinfectant solution to human body.
