Hyderabad Metro introduces ozone-based sanitization of coaches


L&T Metro Rail (Hyderabad) Ltd (L&TMRHL) has become India’s first metro rail to introduce ozone-based sanitization of its train coaches.

Kickstarting the process, it has inducted three portable Ozycare Mobizone units to sanitize the coaches in line with building confidence among passengers for safe travel during the ongoing Covid-19 pandemic.

Sanitization of air and surface by ozone has been widely used in hospitals, healthcare, food processing facilities, and for disinfection of water, among others as per the appropriate guidelines.

Hyderabad Metro Rail has conducted rigorous testing of Ozycare Mobizone equipment on various metro coaches for the past few months, which was followed by testing of the efficacy of the sanitization by a NABL accredited lab.

The units can neutralize more than 99 percent of pathogens from the air and surface of the coaches. Based on its effectiveness, Hyderabad Metro Rail is now using Ozycare Mobizone equipment to sanitize the metro coaches providing a safer traveling experience to passengers.

“These units are robust enough to neutralize more than 99 percent of pathogens both from the surface and air within the train coaches. This is a strategic decision, which we have taken as part of our confidence-building exercise to make the travelers’ journey safer,” said K.V.B. Reddy, MD & CEO, L&TMRHL.

“Especially when we are back on the full-service mode, we hope this move would infuse a sense of confidence among the passengers making them choose the metro as their preferred mode of city commute during the ongoing pandemic.”

Hyderabad Metro Rail has three coaches on every train. As per the process, the individual machines are kept and operated in each coach for sanitization. Ozycare Mobizone Machines are handled in a controlled environment to sanitize the train coaches.

As per the sanitization protocol of this machine, the ozone cycle lasts for less than 10 minutes followed by an ozone destruction cycle that ensures post sanitization safety as per OSHA (Occupational Safety and Health Administration) norms. During this period, this machine sanitizes the entire coach neutralizing more than 99 percent of pathogens from its ambient air and surface.

Being a strong oxidizing agent, ozone (O3) is a great air and surface disinfectant and one of the most effective sterilization tools. It can kill more than 99 percent of 650 different kinds of pathogenic organisms and it is very safe and efficient. It destroys germs, viruses, bacteria, and microbes that may cause surface or air contaminations. Since the distribution happens in gaseous form, it penetrates the gaps and hidden crevices that are hard to sanitize. After its usage, no-rinse is required as it does not leave any residual on the surface.
