Abstract: At approximately 3:30 p.m. on December 21, 2011 Employee #1, a membrane element assembler of Nano H20 Inc., was draining water from a wet membrane element and placed it onto a ground level storage rack. As he lifted the element with both hands, Employee #1 lifted the membrane element from the bath and tilted the element to drain the water from it. As Employee #1 tilted the membrane element, the element slipped out of his hands and began to fall to the floor. Before the element could hit the floor Employee #1 caught the bottom of the element with his left hand, redrained the element, placed the element on the storage rack and continued with his regularly assigned duties. At the conclusion of the work day, Employee #1 left for home with some discomfort in his left forearm. As the weeks passed the discomfort in Employee #1's left arm increased to where on May 24, 2012 Employee #1 seeked treatment for the discomfort in his left forearm. At Los Angeles Orthopedic Center it was diagnosed that the ligaments in Employee #1's left forearm had twisted. On the week of the 24th of May 2012 Employee #1 underwent surgery at Good Samaritan Hospital in Los Angeles to repair the ligaments of Employee #1 left forearm.
