Implementation of work rotation in a metallurgical plant for electronic products.

Abstract

Steel mill industries present problems related to movement repetitions and work complexity. These tasks also demand hand dexterity, promote work related to musculoskeletal disorders and cause worker´s low performance. The aim of this study was to implant the Workstation Rotation with an Ergonomic Approach (WREA) for mounters from the sector of a steel mill of electronic products. The initial process for implanting the WREA was defined considering seven priorities: identification of worker´s abilities; qualification program; ranking to work station; intercalation to double operations; qualification to new workers; accomplishment to qualification; the WREA beginning. It was verified some biomechanical factors in xx most of the mounters´ activities. Most syntoms were present on the shoulder, neck and back. With this methodology, it was possible to establish the WREA based on the priorities, in order to allow less exposition to risk, thus, to musculoskeletal disorders. The WREA methodology, used with Ergonomic Work Analysis, demonstrated to be a cientifical and simple instrument. Keywords: Erognomic Analysis; Rotation of Activities; Mounters
