However, the concentration of acetic acid in vinegar used in general households is very low. Even if heated and vaporized, the concentration can't play a bactericidal role, but if it is rubbed on the contact surface, it still has a certain effect. Therefore, general household fumigation vinegar can't play a bactericidal role, and if the operation method is improper, such as the acetic acid concentration in fumigation vinegar is too high, it will easily lead to symptoms such as dyspnea and nausea, and it will also cause harm to the skin.
In addition, the vinegar is heated to evaporate. If it is some newborns or some patients with respiratory diseases such as asthma and tracheitis, acetic acid is easy to stimulate respiratory mucosa and easily aggravate the condition.
Extended data:
If the concentration of smoked vinegar is too high and the time is too long, the acidic gas emitted by smoked vinegar will stimulate the respiratory mucosa, especially leading to the onset or aggravation of patients with bronchitis, emphysema and asthma. Severe burns to the upper respiratory mucosa, especially for children, the elderly and asthma patients.
In addition to smoked vinegar, many families also use peracetic acid and Lysol water for sterilization. These drugs have strong oxidizing ability and strong acidity, which are not only unsafe for human body, but also corrosive to furniture. If the room must be disinfected, please ask the professionals of the health and epidemic prevention department to spray or fumigate the corresponding concentration of liquid medicine according to the size of the room.
