Chennai, April 2 : With Tamil Nadu entering the deep dark 'coronavirus tunnel' with no light at the end, the knitwear town Tiruppur has got a different kind of a tunnel that tries to keep the people safe. The district has got the 'Coronavirus Disinfectant Tunnel', courtesy D. Venkatesh a businessman from the district. Shoppers at the Thennampalayam Uzhavar Sandhai vegetable market were surprised as district administration officials had asked them to walk through the tunnel having disinfectant sprayers. While one walks through the tunnel for a few seconds, the coronavirus disinfectant sprayers would do their job-spraying one per cent sodium hydro chlorite solution so that the person walks out free of virus infection on his body. The walkers have to raise their hands and their palms facing the front while entering the tunnel. District Collector K. Vijayakarthikeyan stressed the point that tunnel spraying is only an additional precaution and not a substitute for washing hands with soap. The tunnel has a capacity to hold 1,000 litres of disinfectant. /IANS
