Ergonomics Should Drive Injury-Reduction Plan

Today we continue our September 15 post on developing a proactive plan to reduce costly workplace injuries.

2. Set priorities.

After you have determined activities and areas that carry a high risk of injury, set priorities for initiating improvements. Activities resulting in the most severe and most frequent injuries should receive the highest priority, followed by those garnering the highest incidence of worker complaint. Other factors to be considered include technical and financial resources at your disposal and the difficulty in implementing improvements. Be sure to include worker ideas in your plan. Develop a timeframe for making improvements. Communicate the plan and timeline to managers and workers.

3. Implement improvements

Ergonomics — improving the fit between worker tasks and worker capabilities — should drive implementation of your injury-reduction plan. Manual handling of materials and products should be reduced or eliminated wherever possible. Operations and processes can often be combined or restructured to reduce manual tasks. Task procedures can be modified to reduce the strain of unavoidable manual tasks. Ergonomically-designed equipment can eliminate or dramatically decrease the need for physical effort. Don’t neglect proper training for new equipment, procedures, processes, etc.

4. Follow up.

After implementation of each improvement and after allowing for a reasonable adjustment period, it is important to follow up with an evaluation of effectiveness. Review reports and data for signs that injuries, fatigue, discomfort, complaints and risk factors have been reduced or eliminated. Talk to workers to see whether improvements have been accepted and assimilated, that training has been sufficient, and whether there are new complaints. Look for new problems that may have been resulted from the changes made. Refine your plan and made additional improvements as necessary. 

The technical specialists at DJ Products can assist you in evaluating the ergonomic needs of your business. DJ Products manufactures a wide range of ergonomically designed carts, pushers and tugs designed to eliminate and reduce worker injuries.

OSHA Could Stiffen Penalties

OSHA could levy tough consequences on employers who ignore worker safety if Congress passes legislation currently under review. In legislation introduced late last year by Senator Edward Kennedy of Massachusetts, employers who disregard hazards that result in worker fatalities could face felony prosecution and stiff prison sentences. The maximum penalties currently levied by OSHA are 6 months in prison for a willful violation resulting in death and/or $70,000 for a willful violation and $7,000 for a serious violation. Hearings about the proposed legislation are being conducted by the Senate Health, Education, Labor and Pensions Committee. The bill is expected to move through Congress this year.

“Employers who ignore their employees’ safety should pay a penalty that will force them to change their negligent ways,” Sen. Kennedy said. A report issued by Kennedy’s staff titled Discounting Death: OSHA’s Failure to Punish Safety Violations that Kill Workers states that a median penalty of $3,675 was assessed for workplace fatalities last year. “Workers’ lives are obviously worth far more than that,” chided the Senator.

Each year 6,500 American workers die from workplace injuries. According to OSHA estimates, forklifts are responsible for 85 fatalities a year, 34,900 serious injuries and 61,800 non-serious injuries. An estimated 11% of all forklifts in operation in the U.S. are involved in an accident each year. Over their useful life, 90% of all forklifts will be a factor in a workplace accident. Over the past 20 years, forklifts have been the major cause of industrial fatalities and accidents in the U.S.

With stricter enforcement on the horizon, it could be prudent to consider replacing the bulk of your forklift fleet with safer, more maneuverable, ergonomic electric carts and motorized cart pushers. Reasonably-priced cart movers come in a variety of sizes designed to perform many of the same tasks done by forklifts but with increased efficiency and superior safety for workers. Power tuggers offer maximum versatility in moving loads of up to 3,0o0 pounds while cart movers can muscle heavy 50,000-pound loads.

Material Handling Industry Moving to Clean, Green Electric Carts

“Cleaner, greener, smarter.” That’s how John Teresko characterized the material handling industry’s shift to electric battery-powered vehicles in a recent online article on Industry Week. “While the continuing transition to electric battery-powered lift trucks may suggest only environmental concern, the trend is really part of a broader search for new levels of performance and productivity,” he said. Over the past decade sales of electric trucks have gradually overtaken and surpassed sales of internal combustion models. The move to electric power is the most significant, most evident trend in the material handling industry.

While Teresko happened to be writing about forklift trucks, the move to clean-energy, electric battery-powered carts and tugs is universal across the landscape of the material handling industry. Fueled by a growing concern for the environment and skyrocketing fossil fuel costs, savvy businessmen have been trading in their gas- and diesel-powered vehicles in favor of cleaner, cheaper-to-operate electric battery-powered equipment. With the capacity to operate a full shift without recharge, electric battery-powered material handling equipment provides significant energy savings without any loss of productivity.

What Teresko didn’t mention is that forward-thinking manufacturers and business owners are moving away from forklifts altogether in favor of cheaper, more versatile, more efficient, safer, ergonomically-designed powered carts and movers. Heralding the next significant shift in the material handling industry, manufacturers are replacing forklifts with highly maneuverable powered movers that allow greater flexibility of use. Their smaller size and ability to maneuver in tight spaces and highly trafficked areas allow motorized carts and powered cart movers to be employed in a wide variety of tasks, increasing the flexibility and versatility of your material handling equipment resources.

Receiving equal consideration is the appallingly high accident/injury rate associated with forklifts. Ergonomically-designed powered carts, tugs and movers have a proven track record of reducing accidents and musculoskeletal injuries. Switching to ergonomically designed electric battery-powered movers results in a significant savings in medical, insurance, disability and workers’ compensation costs and has been proven to reduce absenteeism and lost man-hours. Investment costs are routinely recouped in the first year after purchase. Ergonomically-designed electric battery-powered material handling equipment is the industry’s next most important trend and savvy business owners are getting onboard.

Use Ergonomics to Improve Lifting Safety

Lifting and carrying are the two material handling tasks that result in the greatest number of worker injuries each year. (See our May 14 post on tips for ergonomic carrying.) Applying ergonomics to material handling tasks that involve lifting reduces the need for reaching and bending and the injury-producing stress those actions can place on the back and shoulders. Ergonomics also strives to reduce the amount of effort and force necessary to perform lift tasks.

Calculations of lift force involve both the amount of weight to be lifted and the time period over which the average worker can lift that weight without risk of developing lower back pain. Under ideal conditions, the maximum weight a typical healthy worker can lift with two hands over an 8-hour period is 51 pounds, according to the National Institute of Occupational Safety and Health (NIOSH). However, a number of variables can significantly reduce the maximum lift weight. 

To decrease the potential risk of injury from lift tasks, both overall work flow and individual work tasks should be evaluated to eliminate unnecessary lifting. Where lifting is necessary, ergonomically designed equipment can be used to facilitate many lift tasks. Workers can also be trained to use ergonomic principles in performing lift tasks to minimize potential injury.

To decrease injuries caused by lifting, follow these suggestions:

  • Use ergonomic electric scissor lift tables and power hoists to lift and lower loads where possible to minimize manual lifting.
  • Minimize the distance materials must be lifted or lowered.
  • Use adjustable powered tugs that allow workers to position lift loads at the appropriate height for maximum lifting power.
  • Tag unstable or heavy loads to alert workers. Promote team lifting of such loads to minimize potential worker injury.
  • Test loads for weight and stability before lifting.
  • Reduce load weights and balance loads to facilitate lifting without injury.
  • Rotate workers between lifting and non-lifting tasks or have workers alternate lifting with non-lifting tasks to avoid over-straining muscles. 
  • Reduce the frequency of lifting and amount of time workers perform lifting tasks.
  • Provide clear access to materials to be lifted to prevent awkward reaching, bending and twisting during lifting.
  • Provide secure grips on materials to be lifted.
  • Provide sufficient foot traction with the floor to increase worker stability during lifting.

Battery Powered Tugger Reduces Injury at Food Processing Plant

At a major food processing plant, workers had to manually push heavy meat carts to maneuver them between processing stations. Concerned about injury risk and worker safety, plant executives turned to DJ Products for ergonomic solutions to their material handling problem. Our experts recommended the CartCaddyShorty battery powered tugger, a motorized cart mover designed to push, pull and maneuver carts that require turning. The battery powered tugger is the most maneuverable tug on the market today with the power to handle most push/pull applications. Most commonly used with carts that have two front swivel casters and two straight casters, the ergonomically-designed CartCaddyShorty attaches to the swivel end of the cart to provide the power necessary for easy pushing, pulling, turning and intricate maneuvering. Heavy carts that usually require two workers to maneuver can be easily managed by a single employee. The battery powered tugger takes the physical burden off your workers, eliminating the exertion and straining that can cause serious and expensive musculoskeletal injuries.Musculoskeletal injuries cost U.S. businesses billions of dollars in medical, insurance, workers’ compensation and lost man-hour costs each year. According to OSHA statistics, back injuries alone cost businesses $12 million in lost workdays and $1 billion in compensation costs annually. The time-lost cost of a single back injury is estimated at $26,000.Through proactive use of the CartCaddyShorty, this major food processer was able to eliminate potential musculoskeletal injury risk at its facility. They also realized an increase in productivity and improved employee moral after introduction of DJ Products’ battery powered tugger. The CartCaddyShorty has also proved effective in hospital, hospitality and retail applications.Click here to learn more and to watch a video of the CartCaddyShorty in action. The world leader in providing battery powered tuggers and equipment movers to the manufacturing, hospital and retail markets, DJ Products offers a full line of ergonomically designed, powered carts, tugs and movers.

Ergonomically Designed Equipment Can Help Employees Work More Efficiently

As we advance into the 21st century there will be more and more talk of how machines can replace people. Certainly, there are a number of professions in which fewer people can find work because machines are being used more often, but there is still a lot of work that requires the human touch. And if your company has jobs that require human effort, why not take good care of your workers? When you use the right equipment, such as a battery powered tug from DJ Products, you can prevent your employees from becoming injured.

DJ Products’ warehouse tugs like the RiderCaddy can increase overall productivity. If your company had carts that required several operators, a RiderCaddy would allow them to be moved by just one operator. The operators eliminated from this responsibility would then be available for other tasks.

Last year, a Forbes.com article made this very point. Instead of giving in to the fear that machines will take over, individuals and companies can find tasks that make better use of an employee’s time. “We mechanize a task, get it done by machines, which frees up humans to go and do something else. Possibly a more interesting something else.”

Your employees could get more done and do it safely when they have equipment that is ergonomically designed. All of our products are battery powered “walk-behind” units, that allow the operator to have increased control, even in tight, difficult spaces. Because of this operating flexibility, our extremely efficient electric cart movers can be used in more applications than standard material handling equipment.

Recognizing Opportunity in the Marketplace

The economic slow down has certainly presented its challenges, but it’s also presented business owners with a unique opportunity to reassess both their products and the marketplace. Savvy business owners are making good use of down time necessitated by decreased sales and lowered production to shift more resources into market analysis and research and development. It’s a move geared to discover new opportunities in the marketplace and position businesses to compete more strongly as the market recovers.

While it’s stripped to its bare bones, this is an excellent time to focus on the most essential aspects that drive the market in which you compete. And that’s a smart thing to do periodically, but a chore that is easily put off in the hustle and bustle of meeting customer demands and production schedules when the market is thriving and you’re focused on sales. While the economy is slow, you have time to focus on the essential needs of your customers and that can sharpen your insight into the primary forces that ultimately drive your business. The process provides opportunities to discover new and innovative ways to meet those needs.

In every industry there are core needs that drive business. Applying new technology to address those core needs allows you to offer customers a competitive advantage they can’t get from your competitors. A down market allows you the time to research and develop new technologies and applications that will allow your business to stand out from the competition and offer your customers a way to compete more effectively in their own markets. This is also a time to explore new applications for your products that can open new, untapped markets for your products. The creation of multiple revenue streams through diversification minimizes your business risk when the economy tightens up.

DJ Products’ own story provides an excellent example of how analysis of core market needs can lead to the innovative application of technology to create unique new products. Early on DJ Products saw a need for the development of ergonomically-designed material handling equipment. You have only to look at U.S. Bureau of Labor and Workman’s Compensation statistics to recognize the high cost in both production losses and worker medical expenses caused by musculoskeletal injuries from moving equipment and products in the workplace. Applying ergonomic design techniques to material handling equipment provided a unique solution that successfully resolved these issues, providing practical and affordable solutions to a core industry need. DJ Products’ continued dedication to developing unique solutions to meet customers’ needs has made us an innovative leader in the material handling industry.

Ergonomics = Respect for Workers

Companies that value and respect their workers are proactive about ergonomics, said Peter Budnick, PH.D., founder, president and CEO of Core 3, Ergoweb and Ergobuyer, at a recent material handling conference. “A well formulated ergonomics strategy supports and accelerates continuous improvement in any organization, facility or supply chain.”

Integration of ergonomic practices and equipment into manufacturing and business operations improves productivity, waste reduction, quality control and safety. Ergonomics can operationalize a company’s respect for people, said Budnick, who added that many companies misunderstand ergonomics and therefore don’t recognize its value. He considers ergonomics “essential in an effective continuous improvement system” in any business or industry. 

Ergonomics takes a human-centered approach to task and tool design. It recognizes differences in the individual characteristics and capabilities of workers and strives to accommodate those variables in the design of equipment and structuring of tasks. The goal of ergonomics is to prevent soft tissue, repetitive motion, repetitive stress and musculoskeletal injuries. Nearly half of all lost work days can be attributed to musculoskeletal injuries. These injuries cost U.S. industry more than $61 billion per year in lost productivity and an additional $20 billion in annual medical and workers compensation benefits.

The value of respecting workers has been proven time and again. Toyota has made it a pillar of its business execution plan. When workers are valued, productivity and quality increase while injuries and negativity decrease. Implementation of an ergonomics program is an important way to show workers that you respect them and value their health and safety. In formulating an ergonomics program, evaluate tasks, equipment and work environment for the following factors:

  • force applied
  • awkward or fatiguing postures
  • repetition or frequency
  • duration, both of the task and the number of times per day it is performed
  • vibration
  • contact pressure
  • velocity of movement
  • environmental factors including lighting, temperature, noise, etc.

The goal of ergonomics is to eliminate the discomfort and stress these factors cause workers. On the DJ Products website, we provide a handy Ergonomic Load Calculator that can assist you in evaluating the force needed to move loads in particular workplace environments. Our experienced staff can assist you in designing ergonomic solutions to that will benefit your workers and increase productivity.

Use Handy Calculator to Determine Your Ergonomic Needs

In our last few posts we’ve been talking about the importance of ergonomics in creating both a safe and healthy work environment and the benefits that can provide to your business. Ergonomically-designed equipment decreases the frequency and severity of workplace injuries, medical costs and disability payments, and absenteeism, while increasing employee morale, efficiency and productivity, and profitability.

With so many benefits, it pays a company to invest in ergonomically-designed equipment, but how can you determine your ergonomic needs? DJ Products provides a useful Ergonomic Load Calculator on our website. The calculator is designed to estimate the amount of horizontal force necessary to move wheeled loads in various workplace environments.

Easy to use, our calculator takes you through a series of questions regarding floor condition, terrain, footing, equipment condition, equipment configuration, use of assembly line when applicable, and load weight to determine the required force to move an average load. A second series of questions factors in human performance qualifiers such as proposed worker, frequency and distance each load will be moved, whether loads are pushed or pulled, and handle height. Using mathematic formulas, a Human Performance Capability is calculated that provides an ergonomic estimate of the amount of force that a single worker should apply to move the load. Calculations are provided for both initiating and sustaining equipment motion. A comparison of the calculated equipment force to the ergonomic limit of force allows ergonomists, health and safety officers, and other professionals to accurately evaluate the ergonomic needs of a company.

The program also offers helpful suggestions that can be used to improve workplace safety. For example, an ergonomic evaluation of a manually-wheeled pull-cart might recommend a specific caster size to reduce initiation force or improve pivoting. It might recommend a maximum weight load for the equipment being evaluated. It is always recommended that ergonomic solutions be immediately implemented wherever force exceeds capacity to prevent worker injury.

Hospital Turns to DJ Products for Ergonomic Solutions

Respect for both its medical personnel and bottom line led a large California hospital to partner with DJ Products. Looking for ways to eliminate potential injuries caused by moving heavy hospital beds, food and linen carts, gurneys and wheeled equipment, this hospital turned to DJ Products for ergonomic solutions that would protect the health and safety of its staff. By implementing an ergonomic program to decrease injuries, the hospital also lowered medical, insurance and workers’ compensation costs. Absenteeism from worker injury and resultant added payroll and overtime expenses necessary to cover those absences also decreased.

Like most medical facilities, this hospital relies not only on paid staff, but also on what is fondly termed the “gray brigade” to function. An army of seniors provides a host of volunteer services to assist the perennially harried staff and enrich the lives of patients. Concern about possible injuries among its aging volunteer force and heavily female medical staff led this hospital to review tasks and procedures and update its equipment with ergonomic cart pullers from DJ Products.

DJ Products is a leader in the manufacture of ergonomic material handling products for the hospital, retail, hospitality, automotive and manufacturing markets. Our CartCaddyLite Cart Puller eliminates the pains and strains that can occur when manually pushing hospital beds, medical equipment and heavy food and linen carts. The battery-powered CartCaddyLite easily maneuvers beds, equipment and carts weighing up to 1500 pounds. Variable speed twist grips allow the operator to travel at speeds of 0 to 3 mph and maneuver forward and backwards in tight hospital rooms and congested corridors. Its compact, batter-operated, 24-volt motor can perform without recharging for an entire shift.

For detailed specifications and to watch a video of the versatile CartCaddyLite Cart Puller in action, visit the DJ Products website. We also make an electric cart pusher for maneuvering heavier carts and equipment up to 20,000 pounds and a versatile powered platform cart for moving heavy boxes and supplies.
