Industrial oxygen cylinders or inert gas cylinders can be converted to medical oxygen cylinders.
Due to the COVID-19 pandemic, the Indian government issued an order on April 22, 2020, permitting the conversion of industrial oxygen cylinders and inert gas cylinders (nitrogen, argon, and helium) to medical oxygen for usage in the medical field. This step was taken to ensure an uninterrupted supply of oxygen to the COVID-19 hospitals across the country. The Petroleum and Explosives Safety Organisation listed standard operating procedures for the conversion. It includes degassing the cylinders entirely, cleaning them with detergents, filling them with water/warm water, draining and drying them, etc.
Amid the second wave of COVID-19, a shortage of medical oxygen was observed across India. Many COVID-19 patients died due to the unavailability of medical oxygen, India Today reported on April 21, 2021.
Reliance Industries started readapting oxygen facilities in Jamnagar, Gujarat, to produce 700 MT/day of medical oxygen. The facility can produce almost 100Mt/ day, which is to be upgraded to 1000MT/day. Also, the government has stopped the oxygen supply for industrial purposes from April 22, 2021.
Hence, it is safe to switch industrial oxygen cylinders to medical oxygen, adhering to all the standard procedures.
