Ergonomics Increase Workplace Efficiency

Manufacturers are shutting factories and slashing jobs in an effort to stop the hemorrhaging from the global economic recession. A recession “always hits manufacturing first and hardest,” said Hank Cox, spokesman for the 10,000 member National Association of Manufacturers. “We’re going into a valley” that looks like it’s going to be “long and deep.”

Economic experts compare this recession to the 2000-2003 slowdown during which manufacturing lost 3 million jobs and never really got them back. Greater initial job loss is expected this time around, but there is hope that as the economy improves a greater number of jobs will be reinstated and that the net job loss will be less than in 2003. Until things turn around, though, everyone will have to work a little harder to pick up the slack.

Increasing the efficiency of your workforce can help business owners trim operating costs. Implementing personnel programs to decrease absenteeism has shown good results but doesn’t address the root cause of the problem. Poor working conditions that place unnatural strain on workers’ bodies take both a physical and mental toll on your workforce. Implementing an ergonomic program in your workplace can not only boost employee morale but eliminate costly musculoskeletal injuries and their associated costs.

Ergonomically-designed powered carts and movers relieve workers of the physical strain and discomfort caused by manual performance of pushing, pulling and lifting tasks. Making an investment in your employees’ health and safety improves morale. And where morale is high, worker efficiency has been proven to increase. But these are the indirect benefits of implementing an ergonomics program in your workplace. Direct benefits include an immediate and permanent decrease in expensive musculoskeletal injuries — particularly back injuries — and the high medical, insurance, disability and workers’ compensation costs they entail.

Workplace injury and illness cost U.S. businesses $171 billion a year. Approximately 13.2 million workers every year are injured in the workplace, resulting in $60 billion in workers’ compensation claims annually. According to OSHA estimates, back injuries account for 1 in 5 disabling injuries. Back injuries alone cost American businesses more than $12 million in lost workdays and $1 billion in compensation costs each year. The lost workday cost of a single back injury is estimated at $26,000.

Implementing an ergonomic program in your workplace can dramatically and immediately impact worker efficiency and your bottom line. Most businesses recoup their investment in ergonomic equipment within the first year.

Applying Six Sigma to Ergonomics Drives Production Gains

Businesses that practice Six Sigma recognize the roll ergonomics can play in creating and sustaining productivity gains. Adoption of a comprehensive ergonomics program that combines implementation of ergonomic practices with use of ergonomically-designed equipment can lead to significant production gains, both immediate and sustainable in the long term. This is in addition to the obvious benefits ergonomics offers in improved workplace safety and reduced injury levels and their attendant costs.

In our last post, we began discussing how Six Sigma’s disciplined, process-oriented, five-step approach to problem solving can be applied to development of a comprehensive ergonomics program. We covered defining problem areas and goals, measuring existing stressors, and analyzing collected data to identify root problems and potential risks. Today, we continue our discussion of Six Sigma’s five-step process and its application to creation of a comprehensive ergonomics program.

Improve. Develop solutions to address the identified root causes of production area problems, set performance standards, and define responsibilities of both workers and managers. Remember to talk to the workers who actually perform the tasks and use the equipment. They can provide valuable input and often offer useful, practical solutions to production problems. Implement your improvement action plan, including necessary staff and management training.

Control. To ensure that productivity gains are sustained over the long term and that they continue to improve, it is important to monitor the established ergonomics program to ensure that performance standards and personnel responsibilities are being maintained. Measurement data should be regularly collected and analyzed to ensure that productivity improvement goals are sustained.

Too often ergonomics programs fail because they are not fully supported by top level management. Particularly now, when manufacturers and other businesses, beset by myriad economic concerns, are forced to run lean, many have shunted plans to implement an ergonomics program to the future. There is general lack of understanding of the significant productivity gains that accrue with implementation of an ergonomics program. By increasing productivity, ergonomic processes and ergonomically-designed equipment can improve your bottom line noticeably. And that is in addition to the proven savings realized from the immediate decrease in workplace injuries and accompanying decrease in medical, insurance, workers’ compensation and lost man-hour costs when ergonomics are employed. Making a comprehensive ergonomics program part of your company’s Six Sigma strategy guarantees it the credibility and top level management support necessary for success and sustainability.

How to Assess Your Ergonomic Material Handling Needs

Poorly designed workstations and task habits can result in serious health and injury problems for your employees. Back injuries, followed by neck and shoulder injuries are the most commonly experienced injuries in material handling settings. Proper ergonomic equipment design and tasking protocols can prevent potential injury.

Ergonomics is the science of fitting the task to the worker, instead of the other way around. Musculoskeletal injuries can result when workers have to pull, push, lift or stretch in the performance of their tasks. Assessing your ergonomic needs can be as simple as having a conversation with your employees.

Begin by closely examining the workplace and tasks. Review error and accident reports to identify potential problems. Observe how employees actually perform their tasks. Talk to the people who actually do the work. They have the best insights into what is and isn’t working effectively. Ask the following questions:

  • Are you in a comfortable position throughout the performance of your job tasks?
  • Do you experience discomfort, aches, pain, fatigue or stress? At what point in your tasks? Specifically what are you doing when you experience discomfort?
  • Is the equipment appropriate, easy to use and well maintained?
  • Are you satisfied with your workspace and tasks?
  • Are there frequent errors? What are you doing when these occur?
  • Do you have any suggestions for improving your workspace or tasks?

Analyze the responses you receive. Small solutions such as repositioning of task elements can often make a significant difference in worker comfort. Even when large-scale solutions are required, such as equipment purchase, the cost will be quickly defrayed in decreased medical, insurance, workers’ compensation, disability and lost man-hour costs.

Ergonomic Equipment Benefits Aging Workforce

America’s workforce is aging. According to the U.S. Bureau of Labor Statistics, employment of workers aged 65 and older increased 101% from 1977 to 2007, nearly twice the rate for total employment — and that doesn’t even reflect the aging Baby Boomer population, the first wave of which is just hitting 65 this year. Slightly more than 50% of older workers now work full-time. From 2006 to 2016, the Bureau of Labor Statistics expects older workers aged 55 to 64 to increase by 36% and workers over the age of 65 to increase by 80%.

The graying of America’s workforce means that business and industry will increasingly need to accommodate the physical strength and endurance limitations of older bodies. Ergonomic equipment and practices will become increasingly important, both to protect workers’ health and welfare and to enable workers of variable abilities to perform the same job. Ergonomics allows businesses to fit the job to the person — no matter the worker’s size, age, gender or physical abilities — instead of forcing the worker to torque his body into unnatural and uncomfortable positions to make the equipment work or get the job done.

Manual material handling injuries account for approximately 35% of workers’ compensation claims. Injuries to the back and upper extremities caused by reaching, lifting and carrying result in an estimated 44% of all lost time injuries. As workers age, the risk of injury increases. The bottom line is that without ergonomically-designed equipment and the institution of ergonomic practices at workstations, you can expect your injury rate — and medical/disability costs — to increase as the age of your workforce goes up. However, ergonomic equipment can level the playing field.

Ergonomic equipment that helps to lift, position and move materials and finished products takes the burden off workers, insures worker safety, and increases worker productivity. Ergonomic equipment improves worker safety and productivity when bending, twisting and reaching are required. Ergonomic design can also allow the height and tilt of containers to be adjusted for easier access. Ideally, you should utilize ergonomic principles in every aspect of your workplace operations to promote worker safety and productivity. As a bonus, you’ll build good morale and save money.

We offer a complete line of powerful, compact, ergonomically-designed material handling products for every application. Contact us today for personalized help meeting your material handling needs.

Election Ushers in Era of ‘Ergobamanomics’

In the wake of Barack Obama’s election, U.S. industry should brace itself for a re-emphasis on ergonomics in the workplace. We are about to enter the era of “Ergobamanomics,” predicts senior editor Austin Weber, coining the phrase in his November 6 post on AssemblyBlog, a function of Assembly magazine which serves the manufacturing product assembly market.

“We’re going to have a government that makes sure workers aren’t put at unnecessary risk,” Obama said while stumping on the campaign trail this summer. It seems likely that increased federal emphasis on the development and implementation of ergonomics standards and legislation will be part of the Obama administration’s plan to revitalize and improve U.S. industry. In numerous studies, ergonomics has been proven to significantly reduce workplace injuries and improve worker health and safety.

While workplace health and safety policy changes may not be immediate — president-elect Obama will, after all, have his hands full with more pressing problems in the first few months of his presidency — a solid Democratic majority in Congress makes it likely that tighter ergonomic standards will see quick passage in the near future. Some industry experts believe that a return to the OSHA standards of the Clinton administration could easily be enacted by Congress within the first six months of the new Obama administration.

The sweeping OSHA ergonomics changes ushered in by the Clinton administration in 2000 were quickly repealed by Republicans when George Bush took office in 2001. OSHA’s scaled-back ergonomics plan of 2002 revised the controversial Clinton-era regulations to focus primarily on the reduction of repetitive stress injuries. During his 2004 Senate campaign, Obama said he supported reviving the more comprehensive Clinton OSHA ergonomic standards. During his presidential campaign, Obama has repeatedly promised to renew the government’s commitment to improving the health and safety of all American workers.

Critics fear that a return to Clinton-era OSHA ergonomics standards would place an additional onerous burden on struggling American businesses. Tighter ergonomics standards could necessitate retooling and restructuring of production tasks. Training programs would have to be developed and executed. Increased record-keeping of repetitive stress and musculoskeletal complaints and injuries would also add to time-consuming paperwork and reporting demands, critics charge.

Despite industry fears, ergonomically-designed equipment and work procedures have the proven capacity to increase production efficiency and substantially cut injury rates. Results are both immediate and long-term, resulting in instantaneous and sustained reductions in medical, insurance, workers compensation and lost work hours while reaping considerable gains in worker satisfaction, production efficiency and improved product quality and customer service.

Use NIOSH Equation to Determine Safe Lifting Parameters

Are you familiar with the National Institute of Occupational Safety and Health (NIOSH) lifting equation? The lifting equation provides valuable guidelines for performing and evaluating two-handed manual lifting tasks in the workplace. It defines the recommended weight limit as the weight of a load that can be lifted by a healthy worker repetitively over an extended period of time (such as an 8-hour shift) without risk of developing musculoskeletal trauma injuries such as lower back pain.

Under ideal conditions, the maximum weight that the average healthy worker can safely lift with two hands is 51 pounds. Of course, in the real world, conditions are never ideal, and the physical ability of each individual worker will also limit maximum lifting weights.

NIOSH identifies a number of lifting conditions that must be taken into account in computing the recommended manual weight limit for a particular task, including:

  • Horizontal and vertical location of the load. The optimal horizontal and vertical lifting position is directly in front of the worker, close to the torso, and between the knees and shoulders, with optimal height being hip height. 
  • Distance the load must be moved. Obviously, shorter distances place less strain on workers.
  • Balance of the load. An asymmetrical load places unequal stress on the worker’s body, requiring greater effort to balance the load during transport. The more symmetrically balanced a load, the easier it will be for a worker to carry.
  • Frequency of the lift. The more repetitions required, the greater the cumulative stress placed on the worker’s body. The amount of time between repetitions is also important. The shorter the time between repetitions, the greater the risk of muscle damage.
  • Hand coupling available. Designated handholds assist with lifting, balancing and controlling an object as it is manually transported. When handholds are not provided, additional strain is placed on muscles during lifting and carrying.
  • Length of time over which lifting will occur. In addition to the number of lifts and amount of time between each lift, the total length of time over which lifting must be performed will also affect worker performance. Repetitive lifting through the course of an 8-hour shift will be create greater risk of injury than lifting for two hours alternated with other activities.

It is important to take these conditions into consideration when determining the recommended weight limit for manual lifting tasks in your workplace. However, given the wide range of variations in both worker physical capabilities and workplace conditions can be realized by utilizing powered carts to move equipment and materials previously handled manually. By replacing manual tasks with powered material handling equipment, companies can realize considerable savings in both production efficiency and lift-related worker injuries. Contact the ergonomic experts at DJ Products for more information.

Ergonomic Design Lowers Risk of Musculoskeletal Injury

Manual material handling (MMH) contributes to more than half a million musculoskeletal injuries a year in the U.S., said a 2007 report published by the California Department of Industrial Relations. A joint study by California OSHA and the National Institute for Occupational Safety and Health (NIOSH) found that “effective ergonomic interventions can lower the physical demands of MMH work tasks, thereby lowering the incidence and severity of the musculoskeletal injuries they cause. Their potential for reducing injury-related costs alone make ergonomic interventions a useful tool for improving a company’s productivity, product quality, and overall business competitiveness.”

Musculoskeletal injuries, primarily strains and sprains to the lower back, shoulders and upper limbs, “can result in protracted pain, disability, medical treatment, and financial stress for those afflicted with them,” warns the report. Such injuries carry a double whammy for employers who “often find themselves paying the bill, either directly or through workers’ compensation insurance, at the same time they must cope with the loss of the full capacity of their workers.”

The report recommends adopting ergonomic solutions that reduce the physical demands of MMH tasks, including:

  • Using simple transport devices like carts to move loads,
  • Eliminating lifting from the floor,
  • Using lift-assist devices like scissors lift tables, and
  • Analyzing and redesigning work stations and workflow.

MHIA Launches New Overhead Group

With a plethora of fatal crane accidents peppering the news this year, crane and hoist manufacturers are taking some safety cues from their ergonomically-savvy brethren in the material handling industry. Joining with the Material Handling Industry of America (MHIA) to form the just-launched Overhead Alliance (OA) group, crane, hoist and monorail industry organizations will be promoting alternative methods of lifting and moving materials that reduce accidents, improve workplace health and safety, reduce product damage, improve workflow, lower costs and reduce environmental impact.

Focusing the combined resources of the Crane Manufacturers Association of America (CMAA), Hoist Manufacturers Institute (HMI) and Monorail Manufacturers Association (MMA), OA will give these affiliated trade associations a common voice within the material handling community. Over the next year, OA plans to launch a campaign promoting safer, healthier, greener alternatives to traditional lift trucks for lifting and moving materials, including the use of bridge, gantry and jib cranes and hoists. Not only are lift trucks notorious gas guzzlers, they account for the majority of serious and fatal material handling accidents.

OA will make its national debut at MHIA’s ProMat international exposition in January 2009 where it plans to emphasize the “lean and green” (i.e. ergonomic and energy efficient) benefits of overhead lifting to handle materials. Safe procedures for manual handling and ergonomic lifting that are designed to improve workplace safety and protect workers’ health are also on OA’s promotion agenda.

Material handling equipment that minimizes manual lifting and carrying prevents injuries. The U.S. National Institute for Occupational Safety and Health (NIOSH) reports that back injuries, primarily from improper lifting and carrying of light loads, cost American businesses $10 to $14 billion in workers’ compensation costs and nearly 100 million work days annually.

A world-leader in the production of ergonomic carts for moving and lifting material and equipment, DJ Products manufactures ergonomically-designed, energy-efficient electric and battery-powered cart pullers, pushers and scissors lifts. Already “lean and green,” DJ Products material handling equipment is built to be energy-efficient while maximizing the health and safety of your workers.

Ergonomic Solutions Can Benefit Your Business

Ergonomic solutions are proven to decrease the incidence and severity of musculoskeletal injuries caused by manual material handling work tasks, reports a 2007 study by Cal-OSHA and NIOSH (see our Aug. 20 post). “Manual handling of containers may expose workers to physical conditions (e.g., force, awkward postures, and repetitive motions) that can lead to injuries, wasted energy, and wasted time,” warns the report. Using ergonomic solutions in the workplace to improve the fit between task demands and worker abilities can significantly benefit your business, the report concludes.

The U.S. Department of Labor defines manual material handling (MMH) as “seizing, holding, grasping, turning, or otherwise working with the hand or hands.” This includes moving individual items or pieces of equipment by manually lifting, lowering, filling, emptying or carrying them. These actions can place extreme stress on workers’ bodies, particularly back, shoulder and arm muscles. (Back injuries are the most commonly reported workplace injury in workers’ compensation claims.)

Ergonomic solutions to material handling seek not only to decrease the physical burden on workers’ bodies, but also to accommodate the wide variety of workers’ abilities and body types. Workers’ abilities will vary with gender, age, gender, strength, stature and a host of other variables. Ergonomic solutions often provide adjustable features to accommodate these differences.

According to the Cal-OSHA/NIOSH report, employing ergonomic equipment and ergonomic task design in your workplace will produce the following benefits:

  • Reduce and prevent injuries;
  • Reduce physical effort by workers by decreasing the forces necessary to perform lifting, handling, pushing and pulling tasks;
  • Reduce risk factors for musculoskeletal disorders;
  • Increase productivity, product and service quality and worker morale;
  • Eliminate production bottlenecks and error rates; and
  • Lower costs by reducing medical, insurance and workers’ compensation claims, lost man-hours, absenteeism and retraining.
