The Cost of Ignoring Ergonomics

Back in industry’s dark ages, equipment was designed to do a task without much thought to the comfort or safety of the worker who would be operating it. Back injuries, tendonitis, carpal tunnel syndrome and other stress and repetitive motion injuries were an aggravating and often debilitating part of the job. The toll wasn’t just on the workers, industry paid a price in decreased productivity, poor product quality, increased medical and workers’ compensation costs, low morale and high absenteeism. The annual price tag for workplace injury and illness is estimated at $171 billion.

That’s a pretty hefty price tag considering that America spends about $170 billion a year on cancer and $164 billion on cardiovascular disease, the country’s two biggest killers. According to an American Medical Association study, each year in America there are 6,500 deaths from workplace injuries and more than 60,000 deaths from workplace-related diseases. Non-fatal workplace injuries number 13.2 million annually with 862,000 illnesses. That’s a staggering price in human suffering and industry dollars. The total cost of workplace injuries is nearly equal to the combined annual profits of America’s 20 largest companies.

But that’s just part of the picture. Workers’ compensation claims already cost American businesses $60 billion annually, according to the U.S. Department of Labor. More than 50% of those claims are for back injuries from lifting, pulling, pushing and straining, says the National Council on Compensation Insurance. In fact, workplace back injuries, which involve lengthy and costly treatment, affect more than 1.75 million workers each year, according to the Bureau of Labor Statistics. Add in the estimated time-lost cost per injury of $26,000 per incident and the prevention of a single injury can result in an immediate savings of $26,000.

This staggering cost and the desire to provide American workers with healthier and safer working conditions gave rise to ergonomics and the beginning of a radical change in the way industry approaches equipment design.

Next time: The rise of ergonomics in industrial design.

Why Ergonomic Equipment Makes Smart Sense

With the loss of time on the job and the expense of injuries billed to Workman’s Compensation or for that matter even the legal representation in a liability law suit, the initial investment in ergonomic equipment for your warehouse and maintenance staff is a good investment.

Wikipedia defines ergonomics in this statement:
“Ergonomics is the scientific discipline concerned with designing according to human needs, and the profession that applies theory, principles, data and methods to design in order to optimize human well-being and overall system performance. [2] The field is also called human engineering, and human factors.”

When you invest in equipment that helps to protect your employees and staff from injury, you are investing in increased productivity, potentially lower legal costs for your business, and better employee morale and health.

Ergonomic engineered equipment may initially cost more than other equipment but in the big scheme they may very well be the investment that you simply should not overlook. With over exertion being one of the leading workman’s compensation claims in a document provided by the State of Washington with an average incurred medical cost of $7,233 the investment in machinery that does the heavy work in the warehouse, factory floor, or facility is simply a smart investment in protecting your business from potential medical expenses and legal fees.

To put this in perspective, just in Washington State alone, the Washington State Department of Labor and Industries reported that in 2008 that there were 24,667 claims for overexertion with a total incurred cost of $178,414,838 with an average claim size of $7,233. This is just for one state! Tally this up in 50 states and employee overexertion is one of the key injuries that many companies can work to prevent by supplying equipment that helps protect the employee from overexertion on the job.

If you are not aware of the new equipment that is available to make your staff work more carefully, prevent over exertion, and to increase productivity, we invite you to visit the website of DJ Products the specialist in pullers, movers, motorized carts, electric cart pushers, and CartCaddy dolly movers. They will be happy to provide the information you need to make the “right “ equipment purchase for your specific needs.

Lifting Tips that Prevent Back Injury

In our last post we talked about the exorbitant cost of back injuries to industry. In both human and financial cost, back injuries take an expensive toll. Application of ergonomic principles to the work space and use of ergonomically designed equipment can reduce potential back injury significantly. But sometimes materials must be manually lifted and moved.

It’s important to train workers in proper lifting techniques. Musculoskeletal injuries, particularly to the lower back, can result when items are improperly lifted. The key to developing good lifting habits is to think about what you plan to do before picking up an object. Practice these safe lifting tips:

  • Size up the load and check surrounding conditions. Get help with the lift if the object looks heavy or awkward. Make sure you have good footing and enough space to maneuver easily. If the object must be carried, may sure your path is free and clear of obstacles.
  • Balance your body. Your feet should be shoulder width apart and beside each other. To provide maximum balance and leverage, your feet should be positioned somewhat behind the object to be lifted.
  • When lifting, don’t stoop. Bend both knees and keep your back straight but not vertical. Tucking in your chin will help you keep your back straight.
  • Use your hands and fingers to grip the load. Called a palm grip, this grip provides maximum security. Remember to tuck in your chin before you lift.
  • Use your body weight to get the load moving. Lift by pushing up with your legs, your body’s strongest muscle group.
  • Keep arms and elbows close to the body while lifting to provide better balance and maximize lift force.
  • If you must carry an object, carry it close to your body and don’t twist. Shift your foot position and turn your whole body to change direction.
  • Remember to watch where you’re going.
  • Bend your knees when lowering an object. Avoid stooping which places unnecessary strain on your lower back. Place the object on the edge of a shelf, bench or other surface and slide it back into position. Keep your hands and feet clear as you let go of the object.

Even when lifting or moving light-weight objects, it pays to develop good lifing and carrying habits. Your back will thank you!

Does Obama Have Muscle to Win Ergonomics Fight?

Like actor Mickey Rourke’s amazing return to the Hollywood ring in The Wrestler, labor is back; and President Obama is in its corner cheering its revival. After eight years struggling on the ropes during the Bush administration, labor has bounced back into the Washington ring and is gaining strength — and it’s bringing the ergonomics fight with it.

“I do not view the labor movement as part of the problem; to me it’s part of the solution,” President Obama was widely quoted as saying recently. During his campaign, Obama repeatedly promised American workers a safer, healthier work environment. Industry watchers have taken that to mean a return to and an expansion of the ergonomic standards initiated during the Clinton administration but quickly rescinded under Bush. With a Democratic-controlled Congress backing him up, Obama appears to have the muscle to force ergonomics back into the legislative ring.

By naming California Democratic Representative Hilda Solis as his new Labor Secretary, Obama appears to be saying to U.S. industry and the U.S. Chamber of Commerce, a long-time vocal foe of ergonomics legislation, “Bring it on!” Although she’s still running the confirmation gauntlet, Solis has received the recommendation of the Senate Health, Education, Labor and Pensions Committee and is expected to be confirmed, possibly as soon as tomorrow.

The daughter of immigrants and union workers, Solis has long ties to labor groups and has been a champion of ergonomics in the workplace since joining the House of Representatives in 2001. Her home state of California is the only state in the U.S. that mandates ergonomic standards that force employers to provide a safe and healthy work environment for their workers. Concerned about the cost of implementing ergonomic standards, those opposed to ergonomic legislation fear that California’s tough ergonomics rules will be used to create a national model.

That Obama would eventually grapple with ergonomics to improve labor conditions has been a given since his campaign days. But there’s been a lot of speculation in the industry and in Washington about how and when Obama would try to take down ergonomic opponents. By calling Solis into his corner, Obama seems to be getting ready to enter the ring. It will be interesting to listen to the President’s State of the Union speech tomorrow night. A direct statement about ergonomics or workplace safety could indicate that the fight is on!

Adoption of Ergonomic Program Can Deflect Workforce Crisis

U.S. industry is headed toward a workforce crisis that will require critical changes in our national paradigm. Our workforce is not only declining in numbers, it is becoming increasingly multicultural. Even more challenging is the fact that workers now entering the workforce expect greater challenge and greater rewards from their jobs than their predecessors. In the keynote speech at last summer’s Material Handling and Logistics Summit, Benoit Montreuil, president of the College Industry Council on Material Handling Education, warned that long-term solutions to the pending workforce crisis will require American industry to adjust its attitude toward its workforce and develop new programs to protect the health and safety of that workforce.

Is OSHA Underreporting Injuries?

At a recent Congressional hearing, critics charged that OSHA is underreporting injuries. In questioning the competence of the federal agency designated to protect the health and safety of American workers, critics cited several independent studies, contending that nearly half of all workplace injuries go unreported to OSHA.

Independent studies cited both reviewed the impact of changes to OSHA’s injury-reporting rules and compared injury data reported to OSHA by employers with that reported to state workers’ compensation plans. In one study, a Michigan State University professor of medicine noted that while workplace fatalities have not declined over the years, reported injuries have declined significantly. He found the data suspect. According to the professor, a decline in injuries should have resulted in a similar decline in fatalities. 

The significant data discrepancies between OSHA and state worker’s compensation plans were attributed to numerous possible causes, including the underreporting of injuries to employers by immigrant workers concerned about job retention, reclassification of workers by employers into non-reporting job descriptions, managers discouraging injury reporting, and several other causes. Reports came just shy of charging employer fraud, criticizing OSHA for relying solely on employer statistics.

OSHA defended its reporting procedures, pointing out that in addition to employer submitted data, each year its agents conduct 250 record-keeping audits of employers. OSHA said audits indicate that 90% of employer-submitted data on injuries and illness is accurate. Defending OSHA before the House Committee on Education and Labor, OSHA assistant secretary Edwin Foulke, Jr. said, “In Fiscal Year 2008, of the almost 57,000 violations issued so far, 80% have been categorized as serious, willful, repeat or failure-to-abate, the highest percentage ever recorded by the agency. We are also effectively targeting our inspections.” While Foulke noted that violations were found on 78% of the construction worksites inspected this year, he contended that OSHA’s diligence is responsible for the lowest workplace injuries, illnesses and fatalities in U.S. history.

ANSI Upholds Construction Ergonomic Standard

The American National Standards Institute recently upheld its adoption of ergonomic standards in the construction industry. Rejecting an appeal by the Construction Industry Employer Coalition to withdraw adoption of the approved voluntary consensus standard on the reduction of musculoskeletal problems (ANSI/ASSE A10.40-2007), ANSI reaffirmed the importance of ergonomic design and safe practices in preventing injuries to construction workers.

The appeal by a coalition of five construction trade associations was the latest attempt to derail the ANSI standard approved last year. The coalition first appealed the ergonomic standard during hearings held in May 2007. An appeals panel found those complaints to be without merit, a decision supported by the American Society of Safety Engineers, and the standard was formally approved on July 23, 2007. Shortly thereafter, the coalition filed the formal appeal that was just rejected.

“We are pleased with ANSI Board of Standards Review’s decision to uphold the approval and publication of the A10.40 standard, said ASSE VP James Smith, CSP.” At ASSE we are committed to the protection of people, property and the environment and this standard is an excellent step in protecting workers from injury and in helping to create safer and more healthy workplaces.”

“National consensus standards, such as A10.40, reflect the insights of the final users and the opinions of professionals who work at all levels of public and private sectors in technology development, safety and health, manufacturing, training, financial analysis, personnel and academia,” said A10 Committee Chair Richard King, CSP, CRSP. “This balanced perspective enables standards to be crafted in a manner that benefits and protects standard users.”

The Rise of Ergonomics in Industrial Design

The staggering cost to American industry (see our previous post), coupled with the movement to make the workplace healthier and safer gave rise to the use of ergonomics in industrial design. Ergonomics is the science of fitting the job to the worker with an emphasis on worker safety and comfort. Its goal is to maximize efficiency and productivity by reducing worker fatigue and discomfort. The implementation of ergonomic principles in America signifies a radical change in the way industry approaches equipment design.

According to Wikipedia, “The term ergonomics is derived from the Greek words ergon (work) and nomos (natural laws)” and was first coined by Wojciech Jastrzebowski in an article written in 1857.  But the idea of ergonomics is not new. In the 5th century BC, the ancient Greeks used ergonomic principles in designing tools and performing certain tasks. Hippocrates’ description of a surgeon’s workplace shows ergonomic principles at work. Frederick Taylor, who pioneered Scientific Management in the late 1800s, sought the optimum method of performing a task. In experiments, he was able to triple the amount of coal workers could shovel by reducing the size and weight of the shovel. In the early 1900s, Frank and Lillian Gilbreth built on his method with their Time and Motion Studies. The Gilbreths worked to increase task efficiency by eliminating unnecessary steps and movements. In application, they reduced the number of motions required to lay bricks from 18 to 4.5, tripling hourly productivity. But it was the industrial demands of World War II that allowed the principles of ergonomics to be applied across a broad range of applications, heralding the modern birth of this new branch of applied science.

California was the first state to adopt an ergonomics standard in 1997, prompting other states to consider similar standards. While there is no overriding federal ergonomic safety standard, the Occupational Safety and Health Administration (OSHA) has developed ergonomic standards for specific industries and tasks. Compliance is addressed under OSHA’s General Clause.

Using Ergonomic Equipment to Reduce Injury Rates

In our last post we talked about the challenges of managing a multicultural workforce in material handling, logistics, warehousing, fulfillment and other businesses. OSHA has reported higher than normal injury and on-the-job death rates for foreign-born Hispanic workers who comprise a growing segment of America’s hourly workforce. While language and cultural differences appear to be at the root of the problem, injury and death rates can be cut by using intuitive, ergonomically-designed, powered equipment to meet your material handling needs.

When communication is an issue, equipment that is easy to operate can improve training speed and reduce potential worker operation errors that can lead to injury. When controls are intuitively designed, communication gaps are narrowed further. What might not be grasped or fully remembered in verbal communication can be intuited by gesture or familiarity with similar equipment. This is not to say that a thorough training and safety program is not necessary, only that easy-to-operate equipment shortens the time between initial training and competent operation. Ergonomically-designed equipment is built around the worker, not the task, making it extremely user-friendly and an excellent choice in multicultural work environments.

Ergonomic material handling equipment that is electric or battery powered can further reduce injury and workplace death rates. In material handling situations, most injuries come from pulling, pushing or lifting loads and are the result of over-stretching or over-straining muscles. Powered equipment removes most of the need for heavy physical exertion from pulling, pushing and lifting tasks. By allowing the equipment to do the heavy lifting, so to speak, fewer situations are presented during the workday that might place workers at risk of injury.

Ergonomic Wheel Design Improves Productivity

In our last post we talked about the importance of wheel design in reducing friction. But why is that important? The answer is that any design element that decreases the force that must be exerted by the operator to manipulate a piece of equipment increases efficiency and decreases the risk of potential injury. The result is greater productivity. This is the goal of ergonomic design both in the design of equipment and the environment in which it will be used.

When a wheeled piece of equipment is used, the operator must first overcome inertia and friction. The initial force necessary to start an object in motion is far greater than the sustained force necessary to keep it moving. Once in motion, optimum sustained, or rolling, force is achieved when a steady, constant velocity is achieved. Any need to decrease or increase velocity requires increased force to combat inertia. This is particularly noticeable during turning and maneuvering when significant force must be applied to change direction. Stopping a piece of wheeled equipment requires the same high level of force as starting it. As when accelerating, the operator must overcome high levels of inertia and friction to decelerate.

The four physical elements required to move a piece of wheeled equipment — starting, rolling, turning and stopping — can place tremendous stress on the operator’s musculoskeletal system. If performing these tasks manually, workers frequently overexert and strain muscles while applying the necessary force to start or stop a piece of equipment. Turning and positioning equipment can cause operators to assume asymmetric body postures during exertion which can cause musculoskeletal injury.

Ergonomically designed carts and tugs seek to achieve the optimal wheel size, type, placement and composition to decrease the force an operator must exert to move a piece of equipment.
