SAFER HANDlING Manual Material Handling-Ergonomics Required By JEAN FEINGOlD D espite the introduction of robotic and other mechanical means of moving materials, manual material handling (MMH) is still an essential part of the supply chain process. To minimize the injuries from the repetitive motion involved in MMH means companies must introduce ergonomic interventions. Two major factors impact the need to improve MMH methods: the available pool of workers and market demands. The pool of workers The workforce is aging. In 1972, the average U.S. worker was 28; today that worker is 46. The number of workers 45 and older has doubled since 1950. AARP says those 55 and up in the labor force are projected to rise to 25 million this year and 32 million in 2025. Why is this happening now? "People are living longer," noted Jim Galante, chairman of MHI's Ergonomic Assist Systems & Equipment (EASE) Council and director, Business Development, for MHI member Southworth Products Corp. "In 2009, when the recession hit, it took a lot of people's retirement plans and threw them out the window. Many people are working longer today because they can't afford to retire." Others work by choice, in part because of a cultural trend suggesting people who stay active will live better, longer and healthier lives. While the heavy lifting, bending, twisting and reaching of MMH seems more appropriate work for young people, many don't want these jobs, preferring to sit at desks and use computers. Older people often lack the computer skills needed for office work but they can be easily trained for the many available warehouse jobs. In addition, obesity is a problem for one-third of the U.S. population. The cost of workers' compensation claims is 6.8 times higher for obese workers and they file twice as many such claims as healthy weight workers. Obese workers have 13 times more lost workdays and have indemnity costs 11 times higher than thinner workers. Most of the injuries they experience are to the back, lower extremities, wrists and hands. The most common causes of these injuries are lifting, lowering and carrying objects which are directly attributable to MMH. Market demands Consumers now demand multiple versions of all sorts of products. For example, each battery manufacturer offers hundreds of different products. "These variations create issues in a warehouse and in order filling," noted Galante. When placing their orders, stores seeking that variety can choose among the hundreds of SKUs on hand. To fill each order, an order picker gets a pallet and moves through the warehouse to find and load the different products to build that order. When the mixed order is complete, the pallet load is wrapped and tagged before being put into the delivery truck. Depending on the mix of batteries, each order picker could lift more than 20,000 pounds during an 8-hour shift. What companies can do About 60 percent of all workers' compensation claims for lost time injuries are associated with MMH. Material handling equipment interventions can dramatically reduce the risk of repetitive Ergonomically correct (left) and incorrect (right) techniques. www.mhi.org * MHI SolutIonS 95 http://www.mhi.org
