The Piano Works in Farringdon has installed a tunnel which sprays visitors with chlorine dioxide and coats the outer layers of clothes and skin.The bar is the first in the UK to use the Gateway spray tunnel, which also requires visitors to have their temperatures taken using thermal imaging cameras. Operations Director Tristan Moffat said the company installed the tunnel to 'give customers the confidence to return to our venues'. His words come as earlier this month bacteria expert Professor Hugh Pennington said there has been a Covid-19 'outbreak associated with pubs' and for '90 per cent of cases, that was how they caught it.' After taking an enormous hit when forced to closed at the peak of the coronavirus pandemic, the bar, pub and restaurant industry is adopting numerous safety measures to ensure their customers do not fear visiting them. The emphasis on safety has been upped after last week it was revealed sales in UK chains were halved compared to July last year.
