Nitrate film was used for X-ray photography for some time , where its flammability hazard was most acute , thus in 1933 , became disused for such purposes , along with its uses for motion-picture films in 1951 , where it was replaced by safety film with an acetate base . Nitrocellulose X-ray film ignition was the cause behind the Cleveland Clinic fire of 1929 in Cleveland , Ohio , which claimed the lives of 123 people during the fire , and a number who were rescued , but died several days later due to inhalation of the toxic smoke
