Ergonomic interventions in lighting products manufacturing plant

Abstract

This study emphasizes on ergonomic interventions at an assembly line in lighting products manufacturing plant located at Shah Alam, Selangor. Subjective assessment and direct observation methods were used to the operators and the workplace at manufacturing plant to uncover the problems. Subjective assessment used included interview and questionnaire via modified Nordic Musculoskeletal Questionnaires (NMQs). Direct observation involved site observations throughout the manufacturing plant completed with Rapid Upper Limb Assessment (RULA). The problems found that workers handled heavy lamps between the work station and poor design of lamp burning test station. Two ergonomics interventions were implemented. Wheel tray was applied for transporting the lamps in the assembly line, and new burning test station was introduced on the table. The implemented designs were simple and cost-effective. The ergonomics intervention was analysed and shown reduced in industrial risks and improved the working condition and occupational safety and health.
