Joseph John Rescue workers waited with masks, stretchers and sheets for bodies as heavy earth moving equipment tried to clear debris of a giant chimney that collapsed Wednesday at the Korba power plant site of the Bharat Aluminium Company (BALCO), killing at least 25 people and trapping many others. Hopes of finding survivors in the mountain of debris have slowly begun to fade. More than 24 hours after the 150 m-high chimney collapsed, civil and police officials were still in the process of compiling a list of missing people. Until this evening, only about one-fourth of the debris could be cleared. With very little space for movement, heavy earth moving machines were trying to remove concrete structures while gas-cutters were being used to cut through mangled I-beams, angles and iron rods.
