Two Factors Have Greatest Impact on Ergonomic Risk

Frequency and duration are the two factors that have the greatest impact on ergonomic risk. In developing or reviewing your company’s ergonomic plan, pay particular attention to the frequency and duration of tasks that stress the musculoskeletal system. Reducing the frequency or duration of these tasks will significantly decrease the incidence and severity of musculoskeletal injuries in your workplace. When not addressed, the frequency and duration of tasks that strain workers’ musculature or skeletal system have been proven to significantly increase the risk and expense of long-term injury and loss of function.

It makes sense that the more frequently a worker is required to perform a pushing, pulling, lifting or carrying task that causes overexertion or strain, the greater the risk of musculoskeletal injury. In fact, the repetitive performance of a task over time takes a similar toll on the body, even when muscle strain is not involved. The longer a worker is required to perform a task — duration — also increases the risk of injury. Interestingly, researchers at the National Safety Council have found that the presence of multiple ergonomic risk factors — as few as two — has a multiplicative rather than an additive effect on the likely development of musculoskeletal injury.

The following actions have been found to effectively reduce the risk of musculoskeletal injury in the workplace:

  • Decreasing the number of risk factors present in the workplace. Ergonomically-designed carts, tugs, scissor lifts and similar material handling equipment can be used to perform manual tasks that involve pushing, pulling, lifting and transporting, taking the burden off workers, reducing injury risk and improving productivity.
  • Providing sufficient recovery time between task sessions. Providing rest breaks allows muscle recovery between work sessions. Rotating workers through a variety of tasks limits their risk exposure. But the most productive solution is utilization of ergonomic material handling equipment that enables repeated performance of a specialized task without injury risk.

Part 2: How Much Can Ergonomics Save Your Business?

As we began discussing Friday, pending health care reform could wind up taking a big bite out of businesses’ bottom lines. Businessmen who take proactive measures to bring down medical costs today will realize significant savings going forward. As we noted in our last post, largely preventable musculoskeletal injuries account for 33% of workplace injuries.

In 2007, U.S. workers suffered 335,390 musculoskeletal injuries requiring a median nine days away from work. National Safety Council statistics for 2008 list the following medical costs for common musculoskeletal injuries:

$15,313 – Upper back
$23,820 – Lower back
$12,726 – Hand, finger, wrist
$21,577 – Arms, wrist, shoulder

And that doesn’t include the cost of missed work days, insurance, workers’ compensation, disability, decreased productivity or low morale. Ergonomics can drastically reduce and generally all but eliminate the risk of musculoskeletal injury. Ergonomics is the science of adapting the equipment to fit the worker. Ergonomics recognizes the breadth of human differences and designs equipment that will accommodate those differences while supporting worker performance. The result is decreased injuries, improved productivity and increased worker morale. Costs go down and profits go up.

All this from a simple, well-designed piece of material handling equipment. Except there’s nothing simple about ergonomic design. Hours of careful observation, consultation, statistical analysis and engineering expertise go into the ergonomic design of each of DJ Products’ powered tugs and motorized carts. Every element in our ergonomic material handling equipment is strategically placed for optimal efficiency and ease of operation by the widest possible pool of workers. DJ Products’ ergonomic carts and tugs significantly decrease the risk of worker injury. Many of our customers report recouping their investment well within the first year of operation.

Don’t wait for health care costs to gobble up your profits. To learn how you can proactively reduce workplace injury, talk to one of DJ Products’ ergonomic experts today.

Protect Industrial Employees from Carpal Tunnel Syndrome

The human body is a well-crafted machine but as wonderful as it is, it has its limits. For tasks that cannot be completed with human power alone, we use machines. It is best for you and your employees if you provide them with machines that act as extensions, working with the human body rather than causing the human form to overexert itself.

At DJ Products our mission is to provide solutions for material handling situations that are ergonomically correct, safe and cost effective. We manufacture machines that eliminate the strains and pains of manually pushing or pulling heavy carts, equipment, or materials.

Some of the wheeled carts that are used in a number of industries are quite heavy and allowing your employees to push these carts on their own may be putting them at risk. For example, our CartCaddyHD cart mover can push or pull heavy material handling carts up to 50,000 lbs.

Not only would such a cart be quite heavy, the necessity of moving it through a warehouse setting requires the kind of twisting and moving that could cause musculoskeletal injury. When attached to the swivel caster, a material handling solution like the CartCaddyHD dolly mover provides the pushing and pulling power that your employees need to turn carts smoothly and with ease.

The CartCaddyHD is just one of our many material handling solutions that offers a variable speed twist grip, allowing an operator to move the cart forwards and backwards at between 0-3 mph, while also protecting the operator from getting carpal tunnel syndrome.

To learn more about the CartCaddyHD and similar material handling solutions, call us at 800-686-2651.

What’s Stress Got to Do with It?

When we think about work stress we tend to focus on its impact on our daily job: cost overruns that threaten to push our project over budget, smoothing the ruffled feathers of a fellow employee, meeting sales projections, etc. But stress comes from multiple sources. There’s mental stress from trying to accomplish a goal, emotional stress from interacting with fellow workers, and physical stress resulting from overexertion. We’re human which means that stress is a daily occurrence, particularly in this economy. The problem is that chronic stress can affect performance — both mental and physical, decreasing effectiveness and productivity.

A new study published in the July issue of the journal Science shows that chronic stress actually rearranges the wiring in our brain. In a study with rats conducted jointly by the U.S. National Institutes of Health and researchers at the University of Minho in Portugal, stressed rats lost the ability to make effective decisions. Effective decision making, whether in the performance of mental or physical tasks, requires humans to choose the most productive option from a field of choices. When stress is unrelieved, people are more likely to make poor decisions. In the study, the portion of the brain associated with goal-directed behavior shrank while the area that controlled habit formation grew. Under perpetual stress, people, just like the rats in the study, lose the ability to make smart decisions and fall back on old habits.

Physical stress from overexertion, overreaching or cramped work platforms were as debilitating in eroding decision-making ability as emotional or mental stress. Interestingly, physical stress accelerated the erosion of mental abilities faster than other kinds of stress. Pain and discomfort seem to act more quickly on human stress thresholds than mere mental irritation. Utilizing ergonomically-designed material handling equipment is one smart way to decrease employee stress.

Invest in Ergonomic Power Movers to Avoid Employee Injury

If you are wondering if it is worth your while to invest in ergonomic equipment like powered movers and warehouse tugs, keep in mind the costs associated with work injuries that are related to overexertion.

According to Risk&Insurance.com, employees who work in construction, transportation and warehousing may need a month or more to recover from injury. You probably need all your staff working at full capacity to complete projects, so having someone out can slow productivity. There are things like illness that you can’t prevent, but you can give your staff ergonomic equipment to help avoid preventable injuries that can result in lost work time and lower morale.

The article from Risk&Insurance.com discussed how,

“The median number of days away from work to recover from occupational injuries/illnesses was eight for the third consecutive year, the BLS [Bureau of Labor Statistics] reported. Transportation and warehousing had the highest incidence rate of all industry sectors, although it was basically unchanged from the previous year…sprains, strains, and tears accounted for 40 percent of the total cases, of which 43 resulted from overexertion.

The back was the body part injured most, at more than one-third”

DJ Products manufactures movers, trailers and tugs that can eliminate the pain and strain of manually pulling and pushing heavy carts or wheeled equipment. Our products are less costly, smaller and more maneuverable that traditional powered equipment. So if you have tried other power movers and found that you were less than satisfied, we think you will be pleased with the functionality of our products.

Please take the time to find a specific electric cart pusher on our website, or call our Sales Engineers for a recommendation on your proper solution. Our Sales Engineer will also be happy to explore custom applications where our base products match primary criteria.

Ergonomic Carts Can Help Struggling Hospitality Industry

Staycations and a sharp decline in business travel during the recession have pushed the U.S. hospitality industry to the edge. In recession for the past 24 months, overall occupancy rates continue to erode despite a slight seasonal uptick in June. Occupancy rates at U.S. hotels, motels and resorts have been falling even more rapidly than before over the past eight weeks and the immediate future doesn’t look good, according to industry watcher Hotelmarketing.com.

Continued concern about family finances and potential job loss have kept families at home. Group travel is down, and tours are being cancelled for failure to meet minimums. Businesses have cut travel to hold the line on expenses. Convention and trade show attendance is down. Hotels and motels are competing for a narrowing traveler pool that has forced many to cut staff until the economy improves and the hospitality industry rebounds.

Savvy hoteliers are turning to ergonomically-designed hospitality carts that allow a single employee to accomplish a greater workload with less physical effort. Ergonomic design eliminates strains and pains that workers can develop from pushing heavy laundry, cleaning and linen carts at hotels, motels, casinos and resorts. Powered housekeeping carts and clean and dirty linen carts allow a single employee to safely manage heavy loads of linens or cleaning supplies.

Powered platform carts and electric carts allow easy and safe movement of supplies, materials, parts or machinery from one area of a facility to another. Compact design permits operators to easily and safely maneuver carts through heavily traveled hotel corridors and narrow behind-the-scenes hallways. Motorized dump hoppers makes trash removal a breeze.

DJ Products, the national leader in the manufacture of ergonomic motorized carts and tugs, offers a full line of material handling products designed to meet the needs of the hospitality industry. Our motorized cart retro kit can be adapted and installed on any cart to increase safety and productivity. Visit the DJ Products website for more information.

Hotels and Hospitals: Powered Carts Can Increase Efficiency & Reduce Strain

Employees in the hospitality industry as well as those working in actual hospitals can benefit by using a motorized powered cart to transport items like linens and cleaning supplies. If your employees are currently using carts that they push manually, consider the strain they may be under and consider switching to powered carts from DJ Products, such as a Powered Housekeeping Cart or a Motorized Clean Linen Wire Cart.

The Powered Housekeeping Cart and the Motorized Clean Linen Wire Cart can haul loads up to 700 lbs. The variable speed twist grips allow the operator to travel between 0-3 mph, forward or backward. Both of these carts can be used for an entire shift without re-charging. As long as they are charged, you do not have to worry that an employee will need to take time away from work tasks to wait while a powered cart charges. These carts can also be customized as needed for different environments.

Powered carts will not only help reduce strain and aches from repeated pulling, pushing and tugging–they may also reduce the time it takes for employees to complete their rounds. All of our products are battery powered “walk-behind” units, allowing better control by the operator, even in tight, difficult spaces. Allowing your workers to use ergonomically designed equipment, like motorized carts, can do a lot to reduce injury and the loss of productivity that goes with it. The proactive implementation of ergonomic policies can improve worker morale and make your operations much more efficient.

Be it a hospital or a casino or a hotel, you need to keep things going around the clock—linens need to be changed and rooms need to be cleaned on a continual basis. Powered carts can reduce the time it takes for employees to get this work completed and they will feel less strain as they finish their tasks.

Wheel Design Is Important Element in Health, Hospitality Equipment

There’s a big difference in the amount of energy and effort it takes to push a wheeled cart across a smooth, flat linoleum floor and a floor covered in carpet. So many factors come into play, including:

  • The design, width and size of the wheel.
  • The weight of the piece of equipment being moved.
  • The depth and nap of the carpet.
  • Whether the transport area is flat or inclined or a combination of the two.

These issues and many others are seriously considered during the design of ergonomic material handling equipment for use in health care and hospitality settings that generally include carpets in some areas. Wheel design can significantly impact the amount of force it takes to maneuver a laundry, food, utility, maintenance or garbage cart or some other piece of equipment across hospital, nursing home, hotel, motel or resort floors.

DJ Products electric cart pushers feature a unique wheel design that provides optimal traction on both smooth and carpeted floors with no discernable transition issues. The ergonomic design of our motorized hospital and hospitality cart pushers removes transition issues as carts move easily from one flooring surface to the next. Changes in grade and friction are negated by ergonomic wheel design that allows smooth travel over and between surfaces. The unique 5th wheel design of our control arm allows safe 180 degree pivoting of fully-loaded carts under the arm. This feature allows workers to turn heavy loads a full 90 degrees without risk of jackknifing the care or needing to manually maneuver the front end of the cart.

The result is safer operation for hospital and hospitality workers and more versatile use of these exceptional ergonomic material handling products.
