If 84 disinfectant is mixed with alcohol, it has not been used in this way in the clinic and is not needed. Both disinfectants are volatile and can be irritating to the environment and respiratory tract. 84 disinfectant and alcohol are chemical disinfectants in the clinic, usually alcohol is used in hospitals for local disinfection of skin, while 84 disinfectant is usually used for disinfection of the environment and surfaces of objects, so the application items and scope of application of these two disinfectants are different. A disinfectant alone can play the role of sterilization, killing the role of toxicity, the clinical simply do not need to mix the two disinfectants, and the two disinfectants mixed use does not increase the role of killing sterilization. Alcohol is a volatile gas, and when disinfecting the skin, due to its volatility, it can play a role in killing and sterilizing. The 84 disinfectant has a much stronger irritating effect on the skin. Usually, 84 disinfectant is not used to contact the skin, and 84 disinfectant is used to disinfect objects or floors, while the 84 solution itself produces chlorine gas in the disinfection process, which is irritating to human respiratory tract. Therefore, 84 disinfectant must be fully diluted with water in the process of use. Content source: Dr. You Lai
