This programme went out on a Sunday night at 10pm in a slot normally, in the 70s and 80s, reserved for all kinds of comedy shows -Judith Hann accidentally killed every human on the planet where they stood - including herself - by spilling that chemical on a TV studio floor- except for the four people that somehow managed to survive it - it couldn’t have lasted longer than it did! I remember the series, but couldn’t remember its title!
