Text For Citation: 01 Item/Group: 104 Hazard: ERGONOMIC

Section 5(a)(1) of the Occupational Safety and Health Act of 1970: The employer did not furnish employment and a place of employment which were free from recognized hazards that were causing or likely to cause serious physical harm to employees, in that employees were required to perform tasks involving ergonomic risk factors (including, but not limited to, repetitive motions, force and awkward postures) resulting in stressors that had caused, were causing, or were likely to cause cumulative trauma disorder(s): (a) Department 17, Station 20S where one employee was performing inspection of and repair of case (operation #595). The evaluation of these tasks indicates that the employee is exposed ergonomic stressors including: re- petition, hand/wrist exposed to agents (vibration, hammering), force applied with one hand, with both hands, from one shoulder, from both shoulders and by twisting, work space constrains worker movements, bending to reach work, twisting to reach objects, stretching to reach objects, shoulders different levels, shoulder reach behind body, reach shoulders forward, reach above shoulders, elbow flexion and extension, hand/wrist extension, flexion, pinch, radial deviation, ulnar deviation and rotation, finger push, abduction, lateral pinch, and medial grasp, and closed fist grip and pinch grip which are causing or likely to cause cumulative trauma disorders. The employer did not implement an effective control strategy to reduce or eliminate such disorders. The injury and illness records for 1990 document a pattern of cumulative trauma disorders associated with this operation. While ultimate responsibility for correcting the hazard rests with the employer, given his superior knowledge of the operation, feasible and acceptable abatement methods to correct this hazard include, but are not limited to, the following: ABATEMENT RECOMMENDATIONS: OPERATION 595 1) Use adjustable work stations. 2) Suspend and counter-weight drill. 3) Provide vibration dampening pad on drill handle. 4) Provide lighter weight pop-rivet gun or suspend and counter-weight the present gun to eliminate forceful exertion. 5) Use more workers to provide greater rest break opportunities to eliminate duration and repetition strain on the worker. 6) Use sit/stand/lean option to eliminate static posture. 7) Use "lazy susan" tray to support shell on work station to reduce need for wrist deviations in handling shell and reduce reaches in the work station. 8) Provide test key with handle to eliminate pinch grip.
