Ergonomics Intervention in Indoor Spectrum Measurement Activities

Abstract:

Engineers in the communication and multimedia industries in Malaysia exposed to the risk factors of work-related musculoskeletal disorders. A comprehensive study was conducted to perform ergonomic studies for indoor spectrum measurement activity to improve productivity and occupational safety and health. The study consisted of two phases, where the participative assessments and direct observations were conducted on 17 engineers. In the first phase, the indoor spectrum measurement problem identification was performed by using the portable and handheld spectrum analyser. The questionnaire, body part assessments and archival operation records were investigated. In the second phase, the ergonomics intervention was introduced with a low-cost trolley that removed the work-related musculoskeletal disorders from the engineers. The same test subject, environments, work procedures and evaluation method in phase one were repeated in phase two. The analysis was done by comparing the findings between both phases through statistical analysis, and the significant improvements of ergonomic interventions were identified. The outcome of the study concluded that the analysis and results meet the main objective.
