Petrogen's liquid fuel cutting torch system has won approval by the US Mine Safety and Health Administration for use in all mines, including underground coal mines. It has many advantages over acetylene or propane torches such as: clean, five-times-faster cuts; a portable tank guaranteed never to backflash up the fuel line; a low-cost fuel that is readily available; and cooler, quieter operation.
