ASSESSMENT OF MAINTENANCE AND FACILITY SAFETY IN SOME SELECTED MANUFACTURING INDUSTRIES IN NIGERIA

Abstract

The maintenance of equipment and safety of facilities is very important to an industry as it determines its performance. This study aims to evaluate the effectiveness and efficiency of safety and mainte*nance practices to ensuring overall operational performance of some selected manufacturing industries in Nigeria.  This paper evaluated the maintenance and safety practices of selected manufacturing industries in Ibadan, Oyo state, Nigeria. It investigated the causes of breakdown, causes of accident and predicted the impact of maintenance and safety practice on production. Questionnaire and personal interaction were employed to collect data on record of maintenance and safety practices, annual record of accidents and machine breakdown from nine manufacturing industries within Ibadan metropolis in Oyo State Nigeria. These were analyzed using existing mathematical models. Equipment maintainability, reliability, availability and causes of equipment breakdown, and accident were evaluated.  Results revealed that average maintainability, reliability and availability were 0.648462, 0.764162 and 0.807242 respectively. Average overall economic implications of minor and serious accidents are#533,324,134 and #896,950,921, respectively. Causes of breakdown were identified to be excess workload, failure of parts, untrained operator and inadequate maintenance while unsafe condition and act are responsible for accident occurrences. The Maintenance, safety culture, planning and management in manufacturing industries need more improvement, in order to ensure waste reduction, optimized operational cost, increased productivity and efficiency. Dynamic development of safety legislations from government is encouraged.
