In the wake of the novel Coronavirus outbreak, disinfectant tunnels are emerging as India’s one of the important strategies to disinfect people and protect against infections.<br />”&nbsp;<br />”A press statement from Dr Dinesh Bhatia, Associate Professor, Biomedical Engineering Department, North Eastern Hill University (NEHU), Shillong informed that a collaborative team of faculty, scientists, doctors and industrialists have developed a tunnel sanitizer based automatic temperature controller device.<br />”&nbsp;<br />”After three months of research, discussions, trials and testing, the machine has been made compact and cost-effective. People entering the tunnel are sprayed with an eco-friendly disinfectant solution coming out of a high-pressure air compressor. It is effective to disinfect different bacterial spores, viruses, protozoa and fungi. The tunnel is designed with a view to reduce the time of sanitization in places where there are people entering in large numbers such as religious gatherings, educational institutions and hospitals.<br />”When a person enters through the tunnel, automatically the nozzle will be activated and a full body along with the cloth or shoes will be sanitized with sprays at high pressure and speed. The disinfecting process can be completed in 3 to 4 seconds. With proper implementation, it can disinfect articles of clothing and shoes for a significant period of time.<br />”&nbsp;<br />”<span style="color: #222222;">The tunnel does not require human control and operates with the help of ultrasonic sensors and microcontrollers. It has two chambers with three different levels of disinfection. In the second chamber, the person entering the tunnel experiences a hot air blast at 50-degree Centigrade. This is to make sure that any bacteria or viruses that could have survived during the disinfectant spray process would be killed through the heat in the second chamber. It is followed by exposure of far UVC light with a wavelength ranging from 207 to 222 nm that has the capability to kill the viruses and is considered to be safe for the human eyes and skin.</span><br />
