The biggest characteristic of alcohol is fast action, generally wipe on the hands for half a minute to achieve disinfection, such as wiping on the surface of the object is still half a minute to achieve disinfection, so disinfection with alcohol wipe does not involve the problem of ventilation, as long as it is wiped with alcohol soon to be able to achieve disinfection, alcohol disinfection do not ventilate after. If the alcohol is applied to a larger space, environment, it may lead to a larger alcohol odor throughout the room. Alcohol should not be selected for disinfection in this case, alcohol for disinfection must only involve smaller surfaces, there are risks when disinfecting large surfaces with alcohol wipe. Alcohol is flammable and explosive, and when it is used in large quantities, the concentration in the air can reach a certain amount, such as a local concentration of 3%, and then it may explode. Therefore, alcohol disinfection can only be applied to small surfaces, without consideration of ventilation after use. Content source: Dr. You Lai
