Abstract: At approximately 7:00 a.m. on August 21, 2007, Employee #1 was performing a visual inspection of all the equipment in the roof maintenance area. Employee #1 saw there was some oil on the frame of the compressor on the floor and clean it with a rag. The rag was caught by the v-belt and pulley when Employee #1 energized the power of the compressor. Employee #1 then deenergized the compressor took off the v-belt and recovered the rag from the pulley. Employee #1 then turned the power back on the compressor when he noticed that the rear belt was twisted. Employee #1, without turning off the compressor, tried to readjust the twisted v-belt into place when his two right hand fingers got caught in the nip point of the v-belt and the pulley. Employee #1 was able to free his right hand and he called his supervisor for help. Employee #1 had surgery on his right pinky tip and they shave some bone on his ring finger to make it even. Employee #1 was in the hospital for one day.
