A disinfectant tunnel, also known as a sanitization tunnel, is a structure designed to spray a fine mist of disinfectant solution on people and objects as they pass through. They were developed as a response to the COVID-19 pandemic to help prevent the spread of the virus. Disinfectant tunnels are often used in public places, such as hospitals, schools, shopping malls, and airports, as an additional measure to protect against infection. However, their effectiveness in preventing the spread of the virus is still a matter of debate, and some health experts have raised concerns about their safety and potential negative effects on human health. It is important to follow the guidelines provided by the manufacturer and health authorities when using disinfectant tunnels.
