LONDON (AP) — American cladding maker Arconic said Monday it is discontinuing global sales of one type of composite paneling for use on high-rise buildings following the deadly fire at a London apartment tower as Britain's government sought to manage a burgeoning fire safety crisis. Thousands of people have been evacuated from four high-rises in north London after inspectors found myriad safety problems that included faulty fire doors and troubles with gas pipe insulation as well as the cladding. Hospitals and school buildings across Britain will also have their exterior cladding tested for flammability as part of an urgent nationwide push to increase fire safety.
