Abstract: On December 12, 1992, Employee #1, a production associate at TRW Technar, Inc., a company that manufactures and tests electronic shock sensor modules for automobile air bags, was assigned to test ACA modules. Her normal one-time module test had been changed to a five-time test. After the second module was tested five times, Employee #1 pressed the appropriate key and reached into the nest to pull the unit out. In that instant, the one-time test activated, closing the clamp on her right hand and catching it between the machine's locking mechanism and the sensor module. The tip of Employee #1's right index finger was amputated. Employee #1, who was hired on June 1, 1992, claimed she didn't receive written communications or inspections regarding the job hazards. The employer was cited for a serious violation, T8CCR 4002(a), and a general violation, T8CCR 3203(a)(3).
