The injured employee was installing the condenser section of an air conditioning unit using an overhead crane. The injured employee was on the back side of the unit trying to secure it as three other employees were trying to ensure the condenser section piping would fit in the pre-drilled holes on the roof. When the unit was lowered, the injured employee's left index finger was caught in a pinch point between the roof of the unit and the condenser section. They sustained a partial amputation to the distal phalanx of their left index finger.
