 In one documented instance, a TIC was used to isolate a smoldering hot spot in a grain storage facility; by isolating and removing only the affected grain, 75% of the stored crop was saved.In another, Tennessee firefighters used a thermal imaging camera to detect a hidden fire inside a cinder railroad bed, resulting in an estimated $500,000 cost avoidance.Thermal imaging cameras have also been reported to be particularly useful for fighting fires in cellulose insulation, and for ascertaining that a structure is safe to reenter after a fire has been put out.
