A case study of smoke detector assembly work method intervention and evaluation.
The study aimed to evaluate a work method intervention in a smoke detector assembly line. High hand gripping forces and extreme wrist postures were found in the smoke detector assembly line at UTC Fire & Security Company in Maine. A fixture was introduced to replace the old assembly method. Electromyography (EMG) and electrogoniometry were used to measure the workers' hand gripping force and wrist motions with both the old and new assembly methods. Results show both hand gripping forces and wrist postures improved significantly with the new method.
