Assessment of Risk in Maintenance and Repairs of Elevators in Nigeria

Elevators are potential sources of serious injuries and deaths to the general public and to workers installing, repairing, and maintaining them. State and local authorities recognize such hazards and require periodic inspections of elevators and escalators. Organizations such as the Nigeria Society of Mechanical Engineers (NSME) have set standards for the construction and maintenance of elevators and escalators and for their safe operation. This paper examines the the elevators installation industry and come up with statistical frequency of accident which tends to reduce the energy efficiency among workers.The methodology involves data analysis of elevator’s accident in Nigeria focusing on the activity of the elevators repairer’s and installer’s and use these data to develop a template that will potray the risk prevalence on every activity of elevators installation process. The  result shows that various death were recorded  at every stages of elevators installation. The results were demostrated at every periodic occurence as illustrated in the yearly interval of prediction. Keywords : accident, death, elevators, harzards,injury, risk, workers.
