Anthropometric characteristics of roadside auto-mechanics: a case study

The study evaluated the relevant/corresponding anthropometric characteristics of the people involved in engine-repair activities. The study was carried out on the selected roadside auto-engine repairers along Lagos-Ibadan express way, in Nigeria. This was with a view to providing ergonomic design data for optimal working condition among this set of workforce and redesigning the mechanics inspection-pit. Material and methods: The static and the functional anthropometric characteristics of the mechanics were measured. The data obtained from 110 auto-mechanics, randomly selected, were employed to evaluate efficient design parameter for roadside workstations. Results: The results indicated that inspection-pit is about 1626 mm deep; seat height ranges between 375 mm and 405 mm; optimal work posture sitting is between 483 mm and 622 mm. Conclusions: Adopting the data presented in this paper in optimizing the auto-mechanics working conditions for effective workplace comfort and productivity among the roadside auto-mechanics in Nigeria will be of immense advantage

Simulation study of typical auto-mechanics tasks

This study evaluates the heart rate of healthy non-mechanics handling predetermined loads, in postures typically used by roadside auto-mechanics during repair. The heart rate for different age groups and work postures of roadside auto-mechanics were determined from the assessment of healthy non-mechanics of the same age limit using a digital premium pressure monitor. Regressions were then developed to predict the heart rates of the auto-mechanics. The result indicated that load and posture adopted by roadside auto-mechanics, accounts for 2.74% and 4.51% of increase in their heart rate respectively, while age accounts for 65.78%. It further revealed that heart rate increases with age and load handled, and also showed that heart rate is highest in bending posture, followed by stooping. In conclusion the developed regression algorithms were sufficiently adequate in predicting the heart rate of roadside auto-mechanics and it also indicated that older roadside auto-mechanics need not engage in arduous tasks

Sustainable Manufacturing in Africa: The Pros and Cons- A Pragmatic Review

Manufacturing is an essential aspect of every thriving economy. It is a driver that cannot be overemphasized. This is so because production of goods and service is what ensures a continuous growth of the economy. It is therefore imperative to ensure the sustainability of this key tool. This study reviews the various elements of manufacturing, the strengths and constraints of sustainable manufacturing especially in Africa. The study concludes that manufacturing is sustainable provided the needed support from key players is available and can drive an economy to fast development
