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.
Highlights
Work related musculoskeletal risks (WMSR) are an occupational problem which electrical maintenance technicians in the radio and television workplace are prone to because of the nature of their job [24]
The aim of this study was to undertake an ergonomic analysis of work-related musculoskeletal risks linked to electrical hazards among radio and television technicians in Enugu State
Despite the fact that there are few researchers on electrical hazards in radio/television technicians in general, the high frequency of electrical hazards and musculoskeletal risks identified in this study is consistent [17]
Summary
Work related musculoskeletal risks (WMSR) are an occupational problem which electrical maintenance technicians in the radio and television workplace are prone to because of the nature of their job [24]. Some of the ergonomic practices can be likened to human posture by which people interact with equipment, tools and machines in the workplaces for effective performance and productivity [14] Such practices are; Stop rapid movement in the electrical workshop, avoid repeated drilling and welding for an extended period of time, use a screw driver instead of a hammer to drive in screw nails, work in proper and comfortable postures, minimize forceful exertion, use suitable work stations, tools and equipment, provide workers with instruction on proper manual lifting techniques, store products such as wire roles, Appropriate work practices encompasses the human practice of designing equipment and work tasks to conform to the capability of the technicians [15]. Okoye (2013), revealed that most modern electronics suffer from disrepair (poor repairs) in the hands of these maintenance workers due to negligence, and some faults are complicated enough to cause more harm in domestic appliances For these and other reasons, an ergonomic analysis of work-related musculoskeletal risks associated with electrical hazards among radio and television technicians is needed in Enugu State
