Care Environment This film highlights how anyone is capable in spotting these sign Sometimes the soft signs of deterioration can be spotted by a carer or health professional. All three film types, and the gelatin binder on them, can be scratched, abraded, and creased. Oils and dirt from your hands can also damage the support and binder, as well as the final image material. Once deterioration has begun, film-base materials are even more prone to handling damage. Its high flammability was legendary since it self-explodes when exposed to temperatures over 150° C in front of a hot movie-projector beam.
