A fire in a high rise block of flats and on the top floor a man forced by the flames on to a balcony cries for help. But no fireman's ladder can reach him and rescue from inside is hampered by an out of order lift wrecked by vandals. Before the fireman could reach him the man died. It happened recently in London. Can it happen again? Can worse happen? How safe from fire are buildings we live in and. work in -the flats, the office blocks and skyscraper hotels? Are the building regulations strict enough? Always obeyed? The recent film Towering Inferno focused attention on a real problem. Men and women who have been involved in such fires talk on film to Harold Williamson , and in the studio Desmond Wilcox discusses ways of making our lives safe from the danger of towering infernos.
