Hazards identified at a jewelry manufacturing facility during a survey conducted by NIOSH in response to a Hazard Evaluation and Technical Assistance request to help identify and resolve potential hazards were discussed. The facility produced custom crafted gold jewelry and employed about 100 workers in ten departments which included casting, stamping, soldering, grinding, plating, waxing, wriggling, bright cutting, repair and design, and packing and shipping. Ergonomic procedures were used to identify biomechanical risks for upper extremity cumulative trauma disorders (CTDs). Tools, workstations, and work methods were evaluated to determine their contribution to risk factors. Results showed that awkward postures, sustained loading, high manual force exertion such as gripping and pulling, and vibrations contributed to biomechanical stress. These features were presented in detail as they pertained to the activities of each department. The investigators conclude that biomechanical hazards for upper extremity CTDs exist at this facility, and make several recommendations to improve design and operations in order to alleviate the problems.
