Mahindra Logistics on Tuesday launched, Oxygen on Wheels (O2W), a free service to augment the availability of oxygen by connecting producers with the hospitals and medical centres. The service has been rolled out in cities such as Mumbai, Thane, Pune, Pimpri-Chinchwad, Chakan, Nasik and Nagpur in Maharashtra with the company deploying around 100 vehicles to overcome the transportation bottleneck with safe and quick transportation to deliver oxygen cylinders on demand, a release said. The service will be helmed by Mahindra Logistics, which is partnering with the administration and local government bodies on this project, Mahindra & Mahindra said. The company also said it is in discussions with the civic administration and government departments to extend the service to other cities as well, including Delhi, which along with other states is facing an acute shortage of medical oxygen.
