An auto detailer is waxing a car for eight$-$hour$-$shift. He uses a waxing buffer $($about $5lb)$ so that he could do more cars per hours. He spends about $50\%$ time as shown in first picture, $35\%$ time as shown in the second picture, and about $15\%$ in the $3^{rd}$ picture. Use both RULA and REBA to evaluate this task. What are the risk factors? What do you recommend? What is your suggestion to improve the job if it is observed to be involved with high risks?
