Ergonomic Analysis of Work-Related Musculoskeletal Risks Associated with Electrical Hazards among Radio and Television Technicians in Enugu State

Abstract

The study aimed at the Ergonomic analysis of work-related musculoskeletal risks associated with electrical hazards among radio and television technicians. The objectives of the study were to determine the factors that facilitate electrical hazard among radio and television technicians, and to examine the factors that prevent electrical hazard among radio and television technicians. The total population of the study was 42, comprising 24 technicians, 8 workshop attendants and 10 workshop supervisors in radio and television stations in Enugu State Nigeria. Survey research design was adopted. Random sampling was used to select the supervisors. Structured questionnaire containing a total of 18 items was the instrument for data collection. The instrument was validated by three experts and reliability coefficient of 0.89 was obtained using Cronbach's Alpha. The way radio/television stations in Enugu are structured has an impact on how technicians handle working instruments like pliers, screw drivers, chisels, and hammers, as well as other possible workplace hazards like nails, pieces of iron, bare conductors, and so on. There should be a standard building with well labeled shelves where tools and equipment are packed so as to promote their efficiency in the workplace. Technicians should also be aware of specific attitudes they have in the workshop and understand their role in hazard management to ensure that they stay fit and healthy throughout their careers. Occurrence of work related musculoskeletal problems should be minimized among radio/television technicians in Enugu.
