    Assessment of Musculoskeletal Discomfort Among Mini-Bus Drivers In Osun State, Nigeria.
    (International Journal of Progressive Sciences and Technologies (IJPSAT), 2022) Sanyaolu, Olufemi
    There have been many reports on the physical factors contributed to the development of work-related musculoskeletal disorders (WMSD) which have a negative influence on the health of employee across different occupations including bus drivers. This study focuses on the assessment of musculoskeletal disorders among mini-bus drivers popularly called “Korope” in the Osun State of Nigeria. This research is based on questionnaires extracted from the standard Nordic questionnaire for the assessment of musculoskeletal disorders (MSDs). The results obtained from the questionnaire showed that the low back, knee and the ankle/feet were found to be the most common areas of discomfort among the population. The elbow showed the least area of musculoskeletal discomfort while the shoulder,upper back, neck, thigh/hips and the wrist/ hands showed moderate discomfort. Some of the subjects experienced at least two of the discomforts

    Development of a High Efficient Manual Furnace Blower of the Local Charcoal-Fired Furnace for Aluminium Recycling
    (Iconic Research and Engineering Journals, 2022-05) Sanyaolu, Olufemi
    The charcoal-fired furnace is usually used for Aluminium recycling for the production of cooking utensils in local small-scale Aluminium recycling industries. The performance of such a furnace and manual operated blower was carried out to determine the efficiency and energy consumption in the cause of electrical power failure. Towards this objective, measurements were taken of the quantity of charcoal used for different melts and their corresponding melting times and temperatures. The wheel gear speed ratio of 1:16 was calculated, the energy used was determined and the efficiency calculated. The efficiency obtained for the furnace and the manual-operated blower was 11.6%. The value was obtained as a result of variable atmospheric conditions, non-uniform speed, and the open nature of the environment and the furnace.

    Safety Risk Assessment in Manufacturing Systems: An Analytic Hierarchy Process Approach
    (International Journal of Engineering Research and Applications, 2022) Sanyaolu, Olufemi
    Safety risks in the manufacturing sector affects activities in manufacturing operations. A poor safety culture results in unplanned downtime in production, accidents, injuries and lost time incidents. Safety risk assessment of manufacturing systems using the Analytical Hierarchy Process (AHP) was carried out in this study. Hazard identification and risk ranking was done using a structured questionnaire to identify the hazards which include rolling/moving shaft, wet floor due to oil leaks and water spillage, clouds of dust, steam leakages/pressurized hose leakages, bad machine guarding, noise, fire, open drains, transporting/carrying heavy loads, lifting heavy loads above shoulder height and poor housekeeping. The risk analysis of these hazards indicated Risk Priority Numbers (RPN) ranging from 2 to 16. The analytic hierarchy process (AHP) for the safety risk assessment was carried out using three criteria, namely; human(employee) safety (HS), machine(equipment) safety (MS) and work environment safety (WES). Each criterion has sub-criteria which were found to be consistent after the AHP analysis, thus, it can be used for decision making. This study identified hazards and risks associated with manufacturing systems and analyzed the safety risks by using the analytic hierarchy process (AHP) approach.
