(1951 UK public information film)

“A fire breaks out every 5 minutes, warns this film. This statistic equated to at that time a staggering 90,000 fires a year and £20 million worth of damage. The Government of the time felt it was high time to warn about carelessness. There are London Transport RTs of course, a Glasgow tram and a nice shot at the end of a London Transport trolleybus.” (thanks Bob Wingrove, who provided these screencaps):
