On February 22, 2002, Employee #1 was performing preventive maintenance on a Can nonaire Air Handler (Unit Model CF-24000-employer's Air Handler Number 4) on the roof of Building 18N and replacing a V-belt on the pulley system.

While Employee #1 was placing the V-belt over the p ulley, the wind blew into the air handler, moving the fan and associated pulley shaft. The fan was a Twin City fan and blower system with Serial Number 011079. The movement of the pulley and the V-belt amputated the tip of his middle finger on his right hand. The accident occurred because the fan, shaft, and pulley wer e not blocked to prevent inadvertent movement, while Employee #1 performed the s ervicing operation. His employer is in the biotechnology industry with emphasis on research and development of human therapeutic treatment for the areas of infl ammation and bone diseases, nephrology, neurology, and oncology.
