Ozone-based Surface and Air Sanitisation of Metro Rail Coaches, Telangana, India

Overview
Ozone is the strongest commercially viable disinfectant known. Though sanitisation of air and surface by ozone has been widely used in hospitals, healthcare, food processing facilities, and for disinfection of water, the adoption of Ozone technology for public space sanitization has always been a difficult challenge due to logistic and safety challenges 

Case study
As per the sanitisation protocol of this machine, the ozone cycle lasts for less than 10 minutes followed by an ozone destruction cycle that ensures post sanitisation safety as per Occupational Safety and Health Administration norms. During this period, this machine sanitises the entire coach. These units have been introduced after rigorous testing on various metro coaches for months and this was followed by testing the efficacy of the sanitisation by a NABL-accredited lab. L&T Metro Rail Hyderabad Limited (L&TMRH) has thus become India’s first metro rail to introduce ozone-based sanitisation of its train coaches build confidence among passengers for safe travels amid COVID-19 pandemic
