Ergonomic Material Handling Solutions Improve Productivity

In our last post we talked about coming trends in warehousing. More companies are starting to outsource certain functions, such as logistics, as part of a program to increase efficiency and improve productivity. Outsourcing allows you to focus on your primary business model instead of stretching your resources to include secondary but essential functions such as logistics. The astute businessperson will realize that outsourcing is but one element of what must be a multi-directional effort to tighten efficiency and improve productivity in these difficult economic times.

Making a careful assessment of material handling equipment usage and associated costs — both direct and indirect — can have a significant affect on your bottom line.

  • With the cost of diesel fuel and gasoline going through the roof, replacing outdated equipment with fuel-efficient electric and battery-powered equipment can save thousands of dollars in fuel costs.
  • Replacing bulking, difficult to move equipment with highly maneuverable powered carts and tugs can improve workplace safety and worker morale and decrease lost man-hours from absenteeism and injury.
  • Installing ergonomically designed pushers, pullers and carts can save thousands of dollars a year in decreased medical, insurance and disability costs resulting from musculoskeletal injuries.
  • Implementing ergonomic practices in the workplace can improve worker morale considerably while increasing efficiency and productivity significantly. Retraining staff to utilize recognized ergonomic practices generally produces an immediate savings from reduced worker injuries and associated medical costs.

Safety Factors Force Decline of Forklift Trucks

“When we think of unsafe operations, a fork lift truck tipping over is about as bad as it gets,” said Fork Lift Truck Association CEO David Ellison. “But it can and does get worse if the operator is not restrained. Indeed it gets a bloody site worse. Many people think this is something that couldn’t happen on their site … but we know it does … and more often than you would think!”

Ellison spoke those grim words in promotion of the European association’s 2008 Safety Conference. In the U.S., OSHA estimates that each year forklifts are responsible for 85 fatalities, 34,900 serious injuries and 61,800 non-serious injuries. Of the 855,900 forklifts in operation in the U.S., the Industrial Truck Association estimates that 11% will be involved in an accident this year. Since the useful life of a lift truck is 8 years, 90% of all forklifts will be involved in an accident during their useful life.

The major causes of forklift fatalities are:

  • 42% tipovers
  • 25% crushed between vehicle and a surface
  • 11% crushed between 2 vehicles
  • 10% struck or run over by a forklift
  • 8% struck by falling material
  • 4% fall from platform on the forks

For the past 20 years, forklifts have been the major cause of industrial deaths and accidents in the U.S. Nearly half of forklift fatalities (42%) occur in manufacturing facilities. Construction settings account for 24% of fatalities, followed by wholesale facilities (12.5%), transportation (11%), retail trade (9%) and mining (1.2%).

The likelihood of serious injury or death has spurred many manufacturers and businesses to limit and often entirely remove forklifts from their facilities. Motorized electric carts and tugs are able to perform most forklift tasks more efficiently, more economically and with much greater safety.

Body Posture Plays Significant Role in Ergonomic Design

Body posture affects the amount of force that must be exerted to move and maneuver industrial carts and equipment. The human musculoskeletal system functions like a complex system of mechanical levers. Posture determines the positioning of our joints which, in turn, determines the reach of each muscle and the force needed to exercise it. Ergonomic design seeks to produce maximum force from each exertion by optimizing body posture. In creating a more efficient piece of equipment, the goal of ergonomic design is to minimize wear and tear and the threat of injury to the human body.

Optimal body posture generally changes a piece of equipment is moved. The horizontal force necessary to put equipment in motion gives way to a more upright stance as less force is needed to keep it in motion. Handle placement can affect the amount of horizontal push a worker is able to supply. Any angle above or below the horizontal plane will diminish the amount of force a worker can produce. The greater the angle, the less direct force can applied to horizontal movement. Due to variations in worker size, adjustable handles or multiple handholds will allow optimal force production for a greater percentage of your workforce.

Foot positioning can also have a significant impact on the amount of force a worker can produce. The greatest push force is generated when the body is in a lunging posture with feet separated, one foot some distance ahead of the other. Because this position places the rear foot beyond the body’s center of gravity, it unbalances the body, placing workers at increased risk for falls and injury. The risk of serious injury increases if push force must be executed on either an incline or decline.

The use of electronic or motorized carts eliminates the burden of force and the risk of potential injury from your workforce. Equipment rather than the worker’s body provides the push force to necessary initiate and maintain movement. Optimal force can be applied regardless of worker size and strength, maximizing the efficient use of your workforce and optimizing task completion.

Electric Carts Ease Strain of Push-Pull Tasks

Pushing and pulling are the two most required actions in industrial and business settings. Unfortunately, pushing and pulling can place extreme stress on a worker’s body, often resulting in back, groin and other musculoskeletal injuries. Injuries can cost an individual business thousands of dollars each year in medical, insurance, disability and lost man-hour costs. An ergonomically designed electric cart pusher and motorized cart puller eliminates the physical strain of manually pushing and pulling heavy carts and wheeled equipment. An investment in ergonomic equipment is a sound investment in the health and safety of your workforce that can save your business thousands of dollars in unnecessary medical and insurance costs.

In manufacturing and distribution settings, the most common solutions to material handling tasks are:

  • to place products, parts and equipment on pallets for handling or
  • to utilize racks, carts and casters to move materials.

Electric carts come in a variety of shapes, sizes and configurations to fit the demands of the task and the capabilities of your workforce. An ergonomically-designed cart mover reduces the amount of force that must be exerted by the operator to maneuver a load. Various cart and wheel configurations are available to meet the needs of any task.

  • Carts, racks or equipment with casters can be easily turned and maneuvered with a CartCaddy power tug that feature a 5th wheel turning method.
  • Carts, racks or equipment with 4 swiveling casters require a cart with back end control.
  • Specialized CartCaddies and an electric tug have been designed to handle carts or equipment that have straight wheels or are on a rail.

Handhold Design Can Improve Worker Efficiency

Most carts have handholds of one sort or another. Handles are such an ordinary part of everyday equipment that it’s easy to ignore their importance in efficient equipment use. But handholds are the link between the operator and the load. Handholds cue the operator on how much force to exert and where to apply it most effectively to move the load. Handhold placement and design on carts can increase or decrease the ease and efficiency with which a worker moves a load.

In evaluating the usefulness of a cart, consider these important elements of handhold design:

  • Handhold Height. Handhold height defines the operator’s posture, and posture determines the amount of force a person is able to generate when moving a cart. Given the difference in human size, no single handhold height will be optimal for all workers. Handholds that cause operators to bend or stoop can lead to musculoskeletal injuries. When handholds are located at the proper height for an individual’s body, he is able to exert maximum force without straining his body. An adjustable handhold system will accommodate workers of various sizes. Other solutions include a continuous vertical handhold system that can be grasped at any point along its length or a series of handholds at varying heights.
  • Handhold Width. Handholds should allow the operator to grip the cart near its outer edge to provide maximum leverage for turning and positioning. However it’s important that hands, fingers or arms not protrude beyond the side of the cart to prevent crushing injuries should the cart come in contact with a wall or other equipment.
  • Handhold Type. The type of handhold can dramatically affect the amount of force an operator is able to exert when maneuvering a cart. Poor coupling, the contact between hands and equipment, can decrease the force an operator can exert by 65%. Handhold shape should not concentrate pressure on any specific area of the hand. There should be no sharp edges or pronounced ridges. Both the palm of the hand and the fingers should be able to contact the handhold which should be wide enough to accommodate the entire hand.
    Note: Pulling tasks require a handhold that can be gripped with the fingers wrapping around the handle. Pushing tasks need only a good surface that provides stable hand/equipment coupling.

Ergonomics Can Significantly Decrease Worker Injuries

Material handlers and laborers suffer more injuries and illnesses than construction workers, truck drivers or, indeed, any other category of workers, according to the U.S. Department of Labor. Material handlers and laborers miss more work days and therefore cost U.S. businesses more money in lost man-hours and higher insurance and healthcare costs than any other worker class.

Numerous studies have proved that ergonomically-designed equipment and systems can significantly decrease worker injury. Many manual tasks necessary during the handling of materials require repetitive motions — pushing, pulling, bending, lifting and carrying — that place undue strain on the human body. These actions can result in sprains, strains, back pain and other musculoskeletal injuries. Back pain is by far the most commonly reported workplace injury in the material handling industry. Treatment is generally lengthy and expensive, gobbling up the lion’s share of healthcare and workers’ compensation costs.

The implementation of an ergonomics program can significantly reduce injuries and their associated costs while improving productivity and worker morale. The Material Handling Industry of America (MHIA) has published a 68-page booklet of tips for improving ergonomics in the material handling industry. Click this link to download MHIA’s free Ergonomic Guidelines for Manual Material Handling. For more information on ergonomically-designed electric and motorized carts, pushers and tuggers, visit the DJ Products website.

Next time we’ll share some of MHIA’s best tips for improving ergonomics in the material handling industry and reducing worker injury and its associated costs.

Electric Tuggers Improve Ergonomics in Material Handling

Improving the ergonomics of material handling decreases worker injuries, improves workplace efficiency and leads to a healthier bottom line. Medical costs, insurance premiums, workers’ compensation payments and lost man-hours soar when ergonomics are ignored. Material handling is one of the most injury-intensive industries, according to the U.S. Department of Labor. Every effort you make to fit the demands of work tasks to the capabilities of your workers (i.e., ergonomics) will decrease costs and ultimately improve profit margins.Material handling requires many actions that can result in serious and expensive musculoskeletal injuries. Repetitive motions, awkward postures and the application of force as workers lift, push, pull, carry and handle materials create daily opportunities for injury. Attention to ergonomics in designing tasks, workspaces and equipment can dramatically decrease the physical demands and injury potential of many material handling activities.Carrying and lifting are the two actions that present the greatest potential for worker injury when handling materials. Today we’ll address tips for ergonomic carrying; on Friday, we’ll share tips for lifting ergonomically.Carrying tasks place stress on the back and shoulders and create contact pressure on the shoulders and hands. When repeatedly strained or overstressed, the effort and force needed to carry materials can cause injury. To decrease injuries caused by carrying, follow these suggestions:

  • Eliminate unnecessary carrying.
  • Minimize the distances materials must be carried and use electric tuggers to carry materials over longer distances.
  • Organize work tasks so that physical demands and work pace increase gradually as muscles warm up.
  • Rotate workers or alternate carrying with non-carrying tasks to prevent overstraining the body and give muscles a chance to rest between efforts.
  • Wear properly fitting gloves to improve grip stability.
  • Reduce load weights and test loads for stability and balance before carrying.
  • Slide, push or roll materials. These actions place less stress on the body than carrying.
  • Use conveyors, slides or chutes to move materials.
  • Use electric tuggers to transport heavy loads.

Is Absenteeism Hurting Your Bottom Line?

The nation’s 300 largest employers reported in a 2007 survey by research firm CCH Inc. that absenteeism costs their businesses more than a quarter million dollars annually in direct payroll costs. Add in lost revenue from lower productivity and unscheduled absences can have a significant negative impact on a business’ bottom line. In these recessionary times, absenteeism can make already slim profits disappear.

Only a third of all work absences are due to illness, said Susan Frear, director of education for the Dallas office of the Society for Human Resource Management. “The rest of the absences are related to having to be someplace else or they just don’t feel like coming in. So a lot has to do with the culture of the place.”

Changes in management style or corporate procedures can make a significant difference in absenteeism rates. “Take a hard look at the climate,” suggests Barb Ashbaugh, owner of Ashbaugh’s Trade Secret, a performance management company. Authoritarian managers “who make employees feel it’s their way or the highway” cause higher levels of absenteeism, Ashbaugh noted. Companies that count “occurrences” instead of individual days absent encourage employees to sneak in a couple of extra days off, warned Nancy Glube, an Atlanta human resources executive.

Retail giant J.C. Penney Co. is trying a new approach that shows promise for both large and small businesses. With 1,500 workers calling in “sick” and another 1,200 out on disability each day, Penney executives were concerned about the impact of growing absenteeism rates on the company’s profit margin. This fall they began project PowerLine. When an employee is absent for 3 days, the PowerLine team swings into action. They communicate with the employee to determine the nature of the absence and whether the employee qualifies for health insurance, workers’ compensation or short-term disability benefits. The team notifies store and department managers and insurance carriers and sends the employee the appropriate forms to complete. Daily absenteeism rates have dropped dramatically.

What has made the PowerLine program so successful in such a short time is the constant follow-up that continues until the employee returns to work. “I’ve found that when someone goes out on disability, that person undergoes a significant event in their life,” said Penney’s benefit manager Jim Cuva, “and if no one checks on them to see how they’re doing, they could stay out longer than necessary.” The PowerLine program is Penney’s way of “letting them know we care.”

Employees who know they’re valued work harder, are more productive and are absent less frequently. Making the effort to create a positive work environment can positively impact your bottom line. On Monday, we’ll talk about how implementing ergonomic practices in your workplace can improve worker morale, decrease worker injury and boost your bottom line.

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.

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.
