These tunnels come in various shapes, sizes and costs, and range from basic contraptions which cost less than 10,000 rupees to high-end steel and chrome tunnels with various sensors and conveyor belts and traffic lights which cost Rs 25 lakh.

For instance, the Indian Railways loco shed in Maharashtra’s Bhusaval has developed a tunnel which costs just Rs 10,000. The tunnel has three nozzles that spray one part per million sodium hypochlorite solution for the three to five seconds that people take to pass through it. It has a tank capacity of 500 litres, which allows it to work non-stop for over 15 hours. But while Railway and other officials insist that the spray is relatively harmless for humans but enough to kill the COVID-19 virus, others are not so sure.

More importantly, a slight variation in the concentration of sodium hypochlorite could lead to mild to extremely serious side-effects, ranging from skin and eye irritation to severe burns.

To avoid dangerous mishaps, It is important that the government quickly formulate and enforce guidelines for these tunnels.
