The Fatal Floor
Typically hard-hitting public information film about the threat posed by combining a rug and a freshly polished floor.
Polish a floor and put a rug on it... you might as well set a man-trap'. We then see the rug dissolving to reveal the large, rusty man-trap in question, a piece of visual hyperbole that has ensured that The Fatal Floor remains one of the best-loved of all British health'n'safety films right up to the sadistically knife-twisting (and finger-wagging) punchline '...and to think he'd only just come from the hospital'. Still, it could have been worse: the victim could have been holding his new baby.
Darklly humorous public information film warning about the danger of slipping on newly polished floors.
