Who Monitors Ergonomic Standards?

With talk that the Obama administration will implement federal ergonomic standards, the question arises: Who monitors ergonomic standards now?

There are a number of governmental and professional groups that write and/or monitor ergonomic standards or guidelines that affect U.S. manufacturers and businesses, most prominently:

  • Occupational Safety and Health Administration (OSHA)
  • National Institute for Occupational Safety and Health (NIOSH)
  • American National Standards Institute (ANSI)
  • International Organization for Standardization (ISO)

OSHA. Created by the Occupational Safety and Health Act of 1970, OSHA’s mission is to provide U.S. workers with a safe working environment. The federal program is administered through the U.S. Department of Labor, but many states also have OSHA programs. OSHA develops specific workplace standards to protect workers’ health and safety and, through a network of inspectors, polices businesses to see that standards are enforced. OSHA also conducts procedural training and education courses.

NIOSH. Part of the Centers for Disease Control (CDC), a branch of the U.S. Department of Health and Human Services, NIOSH was created by the same act as OSHA. NIOSH conducts research and makes recommendations regarding the prevention of work-related injuries and illnesses.

ANSI. A private non-profit general standards organization, ANSI facilitates the voluntary establishment of U.S. standards in many areas. ANSI does not create standards but serves as a neutral forum for the development of voluntary standards by consensus of industry/business groups. ANSI works to standardize the development, manufacture and supply of U.S. products and services.

ISO. The world’s largest developer and publisher of international standards, ISO is a non-governmental network of 159 countries. Headquartered in Geneva, Switzerland, ISO seeks international consensus on a wide range of product and service issues to facilitate trade.

In the U.S., some states — California and Washington — have their own ergonomics rules. Michigan may join their ranks soon if ongoing efforts to block a new state ergonomics rule fail. Industry trade organization may also champion ergonomic guidelines in their efforts to standardize industry practices.

Presently, ergonomics standards are piecemeal, applying to some industries or occupations but not all. Most often, standards are couched as voluntary guidelines with no penalty for non-compliance. At this time, the U.S. doesn’t have a pervasive, all-encompassing set of ergonomic laws that mandate and describe the use of ergonomics across the breadth of American business, nor is there a universal federal mechanism for requiring companies to implement ergonomic solutions and discipline those who fail to do so. Most U.S. industry watchers predict that this will eventually chance under the Obama administration. 

Ergonomic Controls Prevent Carpal Tunnel Syndrome

Constant numbness in the hands, sharp shooting pains in the wrist and up arms, loss of grip strength or even the ability to maintain a grip on objects, loss of feeling in fingers — the symptoms of carpal tunnel syndrome are frightening and the pain is great enough to wake you up at night. Left untreated, the condition is debilitating and can cause permanent damage to your hands.

Because of the serious and debilitating repercussions of carpal tunnel syndrome DJ Products designs all of its material handling equipment with ergonomic controls, handles and handholds. Our goal is to provide ergonomically-designed material handling equipment that protects the health and safety of workers by eliminating the potential for debilitating musculoskeletal injuries, including carpal tunnel syndrome.

Carpal tunnel syndrome is a painful, progressive condition caused when the median nerve, the key nerve in the wrist, is continuously compressed by swollen tissue. The median nerve controls sensations and impulses to the muscles on the palm side of the hand, thumb and all of the fingers except the pinkie. The median nerve runs from the forearm into the hand through a narrow bony passage at the wrist called the carpal tunnel. The carpal tunnel also houses tendons that allow the wrist and hand to move. When repetitive motion activities or repeated stress from pushing and pulling heavy carts irritates wrist tendons, they swell, pressing on the median nerve. The result is numbness, weakness and pain that radiates from the fingertips up the arm.

When workers continue to perform daily tasks that irritate wrist tendons, pressure on the median nerve becomes constant, eventually causing permanent damage. Without nerve support, the individual gradually loses fine motor and may even lose gross motor control of his hands and fingers. He may lose the ability to sense hot and cold. Muscles at the base of the thumb atrophy, and hands can become deformed. Left untreated, carpal tunnel syndrome can cause life-altering disability.

Repetitive motion activities on the job and strain from pushing and pulling heavy equipment are the leading causes of carpal tunnel syndrome in the U.S. According to the National Institute of Neurological Disorders and Stroke, in a 1998 study 3 out of every 10,000 U.S. workers were affected by carpal tunnel syndrome. On average, each worker missed 10 days of work and incurred medical bills of $30,000. Treatment of chronic cases requires surgery and an average 6 to 8 weeks for recovery. Utilizing equipment with ergonomically-designed controls and handles can effectively eliminate the risk of carpal tunnel syndrome.

Safety Is No. 1 When Choosing Material Handling Equipment

Productivity and safety are the two top concerns when business owners buy material handling equipment, with safety being paramount. Unsafe equipment will drag down productivity, while safe equipment will enhance productivity. To handle materials safely, loads must be under the operator’s control at all times. Load capability and handling, maneuverability, control placement and design, wheel placement, tire composition, operator line of sight — there are a whole host of design elements that determine the safe operation of material handling equipment.

Manufacturing material handling equipment that is as safe to use as it is easy to operate drives the design of DJ Products’ material handling equipment. Our products are ergonomically designed to take the physical strain off workers’ muscles, allowing them to work more efficiently and more comfortably. By making equipment adaptable to the worker, ergonomic design allows workers of various body types, ages, and physical skills to perform on an equal footing. Ergonomic design maximizes employee performance by eliminating awkward work postures that lead to the tired and cramped muscles that erode job performance and can lead to injury and disability. When workers are forced to contort their bodies into less than optimal postures to operate equipment, muscles become more quickly fatigued. Not only does fatigue lead to slower task production and longer and more frequent breaks, it increases the risk of injury. Ergonomic design eliminates these problems and ensures each worker a safe and comfortable work environment.

To maximize operator control and line-of-sight, DJ Products’ material handling equipment is designed so that the operator walks or rides behind the loaded equipment. This affords the operator maximum visual sight lines to ensure plenty of time for maneuvering and safe stopping, particularly in crowded or heavily trafficked environments. Conveniently-positioned, ergonomically-designed controls allow easy operation and instant safe stopping power of DJ Products’ battery-operated and motorized carts and cart pushers.

A unique safety feature of DJ Products’ carts and movers is our strategically-designed mover arm that allows our cart movers to pivot a full 180 degrees under the arm once it is firmly attached to a cart or piece of equipment. This allows the operator to turn and maneuver carts and equipment safely without risk of jackknifing the cart while carrying a heavy load.

Driver Demographics Affect Musculoskeletal Injury Risk

EHS Today online, a magazine for environment, health and safety leaders, published an interesting April 24, 2009 article comparing truck driver demographics to risk factors for musculoskeletal injuries. As in any job that requires long hours in a single position, long distance truck drivers are at increased risk for musculoskeletal injury on the job. According to a recent study by Atlas Ergonomics, truck drivers lose more workdays per musculoskeletal injury incident than any other group of workers. Fortunately, risk factors can be predicted and workers protected.

The three-year study of 28,301 commercial truck drivers was conducted from 2005 to 2008. Drivers were primarily engaged in driving and delivering loads with less than 10% of drivers’ activities involving the unloading of freight. A direct relationship was found between injury risk and the physical characteristics of the both the worker and truck cab. The driver population studied was predominately men of slightly taller stature and weight than average.

  • The study found that height caused the greatest discomfort while driving. Taller drivers were forced to contort their bodies to fit into cab spaces, while shorter drivers had to stretch to reach controls.
  • Weight, particularly obesity, significantly increased injury risk factors. Obesity increased driving discomfort to severe levels and, in many cases, resulted in sleep apnea and other sleep disorders that impaired alertness.
  • Driver age was spread across all age groups from young, new drivers to near retirees. Discomfort increased with age and length of service, three to five years of seniority producing greater risk. Injuries to workers 65 and older resulted in longer work absences after injury.
  • While women drivers constituted just 8% of the study group, their smaller stature resulted “in elevated levels of discomfort across all body parts,” according to study results. Muscular strength may also have played a role but was not specifically studied.

While operating material handling equipment is significantly different from long-haul trucking, there are important similarities when workers are forced to maintain steady postures for long periods of time or repeatedly perform the same actions over a shift. The findings of the Atlas Ergonomics study has instructive lessons for material handling equipment purchasers who want to decrease the risk of worker injury in their workplace. We’ll talk about that next time.

Ergonomics Is Back on the Congressional Table

With the Democrats expected to control both the House and Senate come January, ergonomics is back on the Congressional table. In 2001, spurred by business lobbyists, a GOP-controlled Congress killed a Labor Department regulation aimed at reducing ergonomic-related injuries. Heavily supported by Democrats, the measure was, and still is, a top priority for union groups. According to political analysts, it was a stunning defeat for the Clinton White House. With the support of the Bush administration, Republicans have managed to keep the issue off the docket.  However, now that Democratic power is the rise, unions are again pushing for ergonomic regulations.

An internet article on The Hill, a Washington insiders tip sheet, said, “Sen. Barack Obama has promised to issue a new ergonomics regulation as president, and industry officials say they want to be ready for it.”

Chamber of Commerce leaders are mobilizing for a Congressional fight, stating in a recent announcement, “the threat of a new ergonomics regulation has been kept in check by the Republican congressional majorities and the Bush administration. But with the recent shift in power on Capitol Hill, and regardless of who wins the White House, issuing a new ergonomics regulation will once again become a hot issue.”

Naturally, no businessman looks forward to tighter regulations and the time-eating forms, procedures and training that usually accompany them. Particularly in the current economy, we’re all budget conscious and no one’s looking for ways to fritter away more money. But if you look at the statistics, embracing ergonomics makes good business sense.

Workplace injury and illness costs American businesses $171 billion annually. Workers’ compensation claims add another $60 billion to that annual price tag. More than a quarter of those claims are for back injuries from repetitive lifting, pulling, pushing and straining, according to the National Council on Compensation Insurance. OSHA reports that back injuries cost U.S. businesses $12 million in lost workdays and $1 billion in compensation costs each year. The time-lost cost of a single injury is estimated at $26,000.

Ergonomics has been repeatedly proven to significantly reduce back and other repetitive stress injuries like carpal tunnel syndrome. Businesses that institute ergonomic practices and use ergonomically-designed equipment realize immediate and significant reductions in injury rates and associated medical, insurance, disability, workers compensation and lost man-hour costs. Proactive implementation of ergonomic policies improves worker morale and demonstrably increases operations efficiency and productivity. Contact the specialists at DJ Products to find out how ergonomics can improve your business.

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 Products Will Lead Material Handling Gains in U.S.

Material handling equipment can help employees move loads with less manual pushing. Ergonomics considers how the task, equipment and workplace fit the people doing the work. This article introduces applications for powered carts, tugs and vehicle movers; its original publication date remains historical.

Review the handling task

Start with the load’s weight, wheels, connection and travel route. Record how often employees need to push or pull it. A powered mover must suit the load and operating conditions. It is not a general replacement for forklift lifting and stacking.

Choose equipment for the application

DJ Products carts and tugs serve a range of handling tasks. Compare model-specific capacities, controls and connections rather than assuming every unit shares the same features.

Applications include manufacturing, logistics, warehouses, hospitals, hospitality and retail. Consider aisle widths, thresholds and pedestrian traffic when planning a route.

Moving vehicles

Vehicle pushers and pullers can assist with compatible vehicles at service facilities or production sites. Confirm the vehicle’s weight, contact points and the selected mover’s limits before use. Controlled movement and suitable connections matter; equipment does not guarantee freedom from damage.

Include training and maintenance

Train operators for the chosen equipment and site conditions. Inspect the load, coupling and mover, and follow the manufacturer’s instructions. Review broader ergonomic hazards using OSHA’s warehousing guidance.

Contact DJ Products with your load details and route information to discuss a suitable configuration.
