Warehousing and Support Activities for Transportation

In total, 92 workers from a supermarket warehouse were ergonomically assessed, specifically in two tasks—lifting boxes and pulling them. RULA was used in conjunction with other tools. Lifting the boxes affected the workers' lower back, while the other task affected the lower arm and wrist [142]. Using the same method in the same workplace, they assessed the effect caused by a new storage tool. They concluded that it allowed for better work completion and resulted in less back and shoulder risks [141].

Finally, material handling workers were assessed. Sensors capable of measuring angles during a work task were used and, from these data, RULA was applied. The results showed high levels of risk in the postures adopted [137].
