ABSTRACT
Occupational Lifting tasks involving heavy weights have effects on both the health and productivity of the person performing the task especially if ergonomic measures are not adopted. When a person involved in manual materials handling sustains an injury in the course of performing lifting tasks, it often results in wastage of both time and material resources which in turn have multiplier effects on the profit margin of his employer. It is against this backdrop that an assessment of the post ergonomic effects of lifting tasks performed in block moulding industries in Akure, Nigeria was carried out. It was discovered that the thighs (both) are body parts susceptible to stress and discomfort whereas the mid to low back region of the body is the most stressed part of the body. This was attributed to the excessive bending of the 5th lumbar and the 1st sacral (L5/S1) of the spine. When asked to rate their workload, 52% of the subjects rated their occupational lifting task as Hard while 29% of them chose very hard. The average age of the 60 subjects that participated in the study is 29 years having a weight of 61 Kg and a height of 169.17cm.All the subjects were male as no female was seen in all the industries visited which confirmed that the lifting task was actually a hard one involving a weight of 28Kg.
