Safe Vacuuming Because vacuums are the one tool used by almost all cleaning technicians, this task greatly increases the risk that workers will develop MSDs. Most cleaning workers use upright vacuum cleaners, which require considerable hand and arm movement, as well as grip force, to use. Awkward posture is also often required, and the worker must repeatedly lift and carry the machine, then plug it in and unplug it from the wall, all of which can put stress on the back, shoulders, arms, and wrists. Noise and soiled exhaust can further negatively impact the worker. Newer vacuum cleaners have several features that make them easier to use and help eliminate the risk for MSDs. For instance, according to Jolynn Kennedy with Tornado Industries (a leading manufacturer of professional vacuum cleaners), some vacuum cleaners now weigh as little as eight pounds, have 50-foot cords, are quieter, and have HEPA filtration systems that prevent dust from being released from the vacuum’s exhaust. “Another option is to consider other types of vacuum cleaners,” says Kennedy. “For instance, some new backpack vacuums (backpack vacuum cleaners that are worn on the user’s back) have totally redesigned harnesses that are much more comfortable to wear and also stabilize and balance the machine so it is far easier to use.” Goggins also recommends backpacks, noting that studies have shown that backpacks can “increase productivity by as much as 100 percent while requiring no more operator energy expenditure than upright vacuums.” “Furthermore,” he states, “in situations where stairways must be vacuumed, backpack vacuums leave one hand free so the worker can use the handrail.”
