I had one of the removable cylinder types that hadn’t been used for ages, pushed the lever in to connect the cylinder but the sealing ‘O’ ring had split and the gas was escaping but never heard it due to the radio being on. Filled the kettle and turned the igniter and then WHOOSH !! both footwells full of yellow flames for a second or two, luckily I was wearing jeans so never got burned but still bloody hot. Stove turned off and chucked out of the window …
