Ergonomics and Grocery Warehousing

The Occupational Safety and Health Administration (OSHA) has a special webpage where it outlines some of the ergonomic issues that face workers in grocery warehouses that highlights “Traditional Order Picking” as an area of ergonomic concern because this system “accounts for a large number of musculoskeletal disorders.”

In the Traditional Order Pick System, products arrive on pallets and are placed on slots that are stored vertically to make the most efficient use of space. OSHA points out that this system also makes efficient use of employee effort since the pallet is not moved around several times, but only gets lifted once and placed in its correct slot until it is time for the products to be removed to fulfill an order. Employees are also able to take “frequent micro-breaks” as the go from one slot to the next.

However, since there is no perfect system, OSHA also points out the disadvantages of this process: workers are “exposed to a number of musculoskeletal stresses including heavy lifting, bending, reaching, twisting, etc.”

Perhaps you haven’t really examined the systems you have put in place at your warehouse, but if a number of employees have either complained of work-related strain or filed for workers compensation because of injuries, it may be time to look at your processes.

Even if you are not able to rearrange your warehouse, change the way products are delivered, or alter the way orders are fulfilled, you can make certain that your employees have material handling solutions that can help minimize strain. DJ Products offers power pullers and industrial power movers that can help workers fulfill orders without undue strain.

Simple Measures Can Improve Warehouse Safety, Productivity

The bottom line advantage of improving worker safety was a recurrent theme this past week as businesses celebrated North American Occupational Safety and Health Week. The annual cost to American businesses of workplace injuries and illnesses is $171 billion. Safety improvement need not come at the expense of efficiency and productivity was the oft-promoted lesson.

“When it comes to improved productivity, safety is an overlooked area,” said Michael Davis of Sedlak Management Consultants. “A lot of times, you don’t realize how much a workmen’s compensation claim costs or the hit you take to morale and productivity if someone gets hurt on the job.” Davis suggested four easy fixes for creating a safer, more productive work environment in warehouses and distribution centers:

  • Create designated walkways for pedestrians and equipment. This is particularly important when forklifts or other equipment must share the same floor space with pedestrians. A low-cost solution can be as simple as outlining walkways in yellow paint and installing guardrails to protect pedestrians from equipment traffic.
  • Install an alert system to warn pickers of coming traffic. Mirrors can also be installed to help workers track the activity of others, particularly when picking areas are crowded or are shared by both pedestrian and vehicle traffic. Davis says an alert system can be installed for $1,500 to $4,500, a fraction of the cost of a workmen’s compensation claim.
  • Safety gates that protect mezzanines are required by OSHA. Unfortunately, most safety gates are manually operated and may occasionally be left open. Installing a safety gate that closes automatically better protects high traffic areas.
  • Sensors around automated equipment can protect workers from inadvertent injury. Robotic pickers and palletizers are often used alongside human workers to improve productivity in picking and shipping operations. Davis suggests, “the installation of a light curtain around automated equipment. That’s  a system of photoelectric eyes that create a barrier around the equipment. If the beam from the photoelectric eye is broken because someone is in that area, the equipment automatically shuts off.”

Ergonomic Scissors Lift Adjusts to Workers’ Heights

Bending, twisting and reaching all day long can have workers reaching for the Tylenol well before the day is over. These muscle-torquing activities lead to aches, strains and sprains that slow workers down and can eventually cause musculoskeletal injuries that entail multiple doctor’s visits, costly physical therapy and time off from work, placing an added burden on fellow workers who have to pick up the slack.

This was the problem being experienced by an Ohio manufacturer of aftermarket exhaust systems. Management noticed a high level of sprains and strains reported by workers. Investigation found the culprit to be the awkward positions workers assumed while performing production and packing tasks.

Workers come in different shapes and sizes but, as is true in most facilities, materials were delivered to work stations at a single, stationary height. Since few workers fit the “ideal” height around which equipment and tasks were designed, this meant that most workers, being either shorter or taller than the “ideal” height, were forced to bend, stretch, and strain to perform their work tasks. In the process, they overtaxed and injured muscles.

Company management sought a solution in ergonomics. Ergonomics is the science of fitting equipment and tasks to the capabilities of the worker to eliminate strain on the human body. Ergonomic design allows equipment that will be used by multiple workers to be adjusted to fit the size and capability of each individual. 

In the case of the Ohio exhaust manufacturer, the perfect solution proved to be an ergonomically-designed, portable scissor lift. The portable scissor lift allowed relatively heavy parts (120 lbs.) to be quickly moved from one station to the next. The power scissor feature permitted each worker to quickly and easily adjust the lift bed to the optimal height for his size. The result was virtual elimination of musculoskeletal injuries, an increase in productivity from 65% to 88%, and increased on-time delivery.

The problems experienced by this Ohio company are common to many industries, including manufacturing, fulfillment, packing, logistics, shipping and warehousing. DJ Products’ PWP2000 Cart Puller mobile electric lift table could be the perfect solution for your facility. Our ergonomically-designed, self-propelled electric scissor lift is available in a variety of shapes and sizes for various applications. Our lift tables deliver work items to the appropriate height every time. Combine our lift table with our PartsCaddy mobile platform truck and workers can easily move fully-loaded lift tables from one station to the next without physical strain. With 16 hours of battery life, DJ Products’ electric movers can stay in continuous operation through two shifts with ease. 

Ergonomic Solutions for Warehouse Order Fulfillment

If your business relies on a warehouse to ship goods to your customers then you know that getting orders is only half of the battle. Once you have secured a customer’s order, it is then up to you and your team to see to it that the order reaches that customer in good condition as quickly as possible. We have no doubt that you have stressed the importance of filling orders quickly to your employees…but have you given them the right equipment to make this happen? It is important to give your employees the supplies so they can carry out your vision.

When employees are working as quickly as possible but using outdated or inadequate machinery, they are more prone to injury. In addition to this, rickety carts, unstable dollies, and overused scissor lifts can result in spilled or damaged merchandise. Having employees out on leave because of injury and losing merchandise to accidents can eat away at your profits and you do not want that.

DJ Products offers and entire lineup for industrial ergonomic material handling solutions including:

• Carts with casters
• Carts with 4-swivel casters or wagon-wheel style of turning
• Carts in a straight line
• Platform Trucks & Scissor Lifts

Our ergonomic cart pushers, electric cart pullers and other solutions eliminate the strain of manually pulling heavy product, parts carts, or wheeled equipment. Your employees can continue to work efficiently with a reduced chance of injury or product damage.

Five Important Dock Safety Tips

Warehouse safety begins at the receiving and shipping docks. Safe dock procedures set the stage for the safe unloading, handling and storage of materials as well as the packing, loading and shipping of product. Identifying and addressing ergonomic challenges on the dock can directly impact worker safety and dock productivity. “You have to look at everything from what kind of trailer you’re going to receive, to whether the load is floor-loaded or unitized to what happens to it after it comes off the truck. Even the temperature inside the facility and the weather are important,” explained Brent Tymensky, VP of design engineering for Fortna Inc.

Dock safety begins with attention to five important issues:

  • Trailer access. The length, width, height and suspension system of a trailer generally determine the dock equipment needed. Other considerations include whether the trailer is dry or refrigerated and whether the load is unitized and fully cubed.
  • Dock conditions. Temperature and weather impact dock worker safety and efficiency. A canopy that keeps out cold, heat, wind, rain and snow improves working conditions and worker comfort. Air-inflatable dock seals can form a tight barrier around a trailer, keeping out the weather and reducing energy costs.
  • Personnel issues. The age, experience and physical condition of your workforce are factors that determine how and when automated and manual equipment are used. Adjustable conveyors that reach into a trailer can assist with manual unloading and loading procedures, reducing the physical strain on workers. While some palletized loads can be off-loaded as is, many pallet loads must be broken down manually into their components for use or proper storage. Adjustable carts and tuggers can make this work both easier and safer for dock workers.
  • Dock safety equipment. Vehicle restraint devices prevent trailers from exiting prematurely while workers are still on the trailer. Restraint devices range from simple wheel chucks to automated systems that bolt into the cement dock and attach to the trailer’s rear guard. A newly marketed interlocking device attaches to the trailer brake emergency airline to prevent the trailer from moving until the dock ramp is removed and the dock door closed.
  • Productivity and efficiency. Dock levelers, extendable conveyors and palletizing equipment all increase efficiency in retrieving and loading materials and goods. Trailer drop can significantly hinder the transition from the trailer to the dock. Levelers and vehicle restraints that support the rear of the trailer can eliminate trailer drop as equipment is moved into the trailer for loading or unloading.

Why Are Ergonomics Important?

We’ve been getting back to basics in our last couple of posts on the history of ergonomics and ergonomic terms, reviewing what ergonomics is for those new to our blog. But why are ergonomics so important in the workplace? Three reasons:

  1. Ergonomics improves worker health and safety.
  2. Ergonomics increases productivity and work quality.
  3. Ergonomics saves money.

Health & safety. People come in all shapes and sizes, but until the advent of ergonomics, material handling equipment was one size fits all. Except the problem was that it didn’t fit all people. Workers taller or shorter than the fictional “average man” to whose size and shape equipment was designed had to reach and stretch or hunch and bend to reach and manipulate equipment controls, to load and off-load product or materials, or to push and pull carts from one work station to another. All that stretching and scrunching around puts stress on the body’s muscles, joints and tendons. Backs become sore, arms and legs tire more quickly, and neck and shoulder muscles start to ache. At first the body heals itself, repairing minor muscle tears, but repetitive stress simply doesn’t allow enough time between exertions for the body to heal. Muscles, tendons and joints can be damaged. Called musculoskeletal injury, this damage can become permanent over time, resulting in permanent disability.

Ergonomics addresses this problem through flexible, adjustable design that allows equipment to be adjusted to the size of each individual worker, ensuring ideal positioning and maximum operator comfort during work tasks for every worker. A national leader in the manufacture of ergonomically-designed motorized carts, DJ Products incorporates a host of important ergonomic features into its material handling products, including:

  • Heavy-duty, battery-operated motors easily move loads up to 50,000 pounds, removing the need to physically push and pull carts.
  • Scissor lifts quickly position materials at the proper height for each individual worker.
  • Well-positioned ergonomic twist-grip hand controls prevent carpal tunnel syndrome by minimizing wrist movement.
  • A variable-speed feature incorporated into the twist grip allows operators to safely control cart speed between 0 and 3 mph while moving either forwards or backwards.
  • A conveniently placed safety stop switch permits instant stops in case of emergency.
  • Added weight over the drive tires creates greater traction, allowing the handling of heavier loads.
  • A specially designed connecting arm allows loads to pivot a full 180 degrees, ensuring safe turning without jackknifing.
  • Walk- or ride-behind equipment construction provides clear sight lines for safe operator control.

Ergonomically Designed Tugs Let You Transport Large Equipment

Our material handling solutions are compact, battery powered “walk behind” units that can help people transport heavy loads with control in numerous situations. Whether you have plenty of room in which to maneuver or you need to move something within a tight, difficult space, we may have an electric or motorized cart tug that can help. You would be surprised at how the proper design makes it possible for a little machine to allow you to move something very heavy. The machine does not need to be as big as or larger than the object being moved when it is engineered properly.

Airplanes?
Yes, you can move an airplane with our aircraft tug. And when we say you, we mean that you can complete this task on your own using the power of our aircraft tug.

Vehicles?
Our car pusher and trailer movers can move vehicles and pieces of equipment with that have straight wheels or are on a rail.

Dumpsters?
Most people wouldn’t try to move an airplane, alone but they might consider themselves strong enough to push a dumpster…what they don’t factor in is the strain this can cause. Just because you can do it doesn’t mean that you should do it. A DJ Products dumpster mover can help you avoid unnecessary muscle strain and pain.

At DJ Products, our goal is to provide solutions for material handling solutions that are ergonomically correct, safe, and cost effective. If you are wondering just how one of our products can help you, feel free to call us at 800-686-2651 and talk to one of our Sales Engineers.

Ergonomic Design Makes the Motorized Cart Workhorse of Future

Ergonomic design, energy efficiency and versatility make DJ Products’ motorized cart the material handling workhorse of the future — or at least the next decade. Our battery-powered and motorized carts and cart movers seem tailor-made for the federal government’s push to improve workplace safety, reduce medical costs, save energy and put more people back to work.

  • Improve workplace safety. The Obama administration is poised to increase governmental regulation of workplace safety issues. Ergonomics will play an important role in creating safe working environments. The science of designing equipment to fit the physical attributes and abilities of the worker, ergonomics reduces discomfort and fatigue and prevents repetitive strain injuries that can lead to long-term disability.
  • Reduce medical costs. With Congress revamping the national health care system, businesses will be working even harder to bring down medical costs. By preventing expensive musculoskeletal injuries, ergonomics helps businesses drastically reduce medical costs, worker’s compensation expenses and medical insurance premiums.
  • Save energy. The President’s promise at the U.N. Copenhagen climate conference to drastically cut the nation’s carbon dioxide production places renewed emphasis on equipment that isn’t powered by CO2-producing fossil fuels. DJ Product’s motorized carts and tugs use clean, green battery or electric power. Just like the Energizer Bunny, our tugs keep going and going, operating through two full shifts on a single charge.
  • Put people back to work. With most of the country starting the year with double-digit unemployment, putting people back to work is the government’s primary 2010 goal. Ergonomic design makes it possible for workers of any size, age or sex to easily operate any of DJ Products’ versatile motorized carts. Intuitive design and conveniently placed controls make for safe operation with minimal training.

How Ergonomics Increases Productivity and Quality

In our last post we talked about how ergonomically designed material handling equipment improves worker health and safety by reducing expensive and potentially debilitating musculoskeletal injury. Business owners also realize measurable increases in worker productivity and product quality when ergonomic equipment and procedures are introduced into the workplace.

Most industrial equipment and work procedures were originally designed for occasional use, not the high-pressured, repetitive, long shifts found in the modern work place. By designing equipment that adjusts to the physical size and capabilities of each individual worker and by structuring work procedures to eliminate uncomfortable body positions during task performance, ergonomics decreases fatigue on muscles while increasing worker comfort. This enables workers to continue working comfortably without the frequent breaks they would otherwise need to stretch and rest tired muscles. Workers remain fresh and energized and can work comfortably through an entire shift. The result is decreased injury, better worker morale and increased worker productivity resulting in improved product quality. Ergonomics produces a win-win scenario for business owners and their employees.

Implementation of an effective ergonomic plan requires a three-pronged approach that involves engineering, administration and work practice modifications.

  • Engineering modifications may include changes in equipment and tools used, workstation modifications and changes in the way tasks are performed. Because engineering modifications produce the greatest reduction or elimination of physical risk, they also result in the greatest cost savings. Reduced physical risk reduces the medical, insurance, disability and lost man-hour costs of potentially debilitating musculoskeletal injury. On its website, DJ Products provides an invaluable Ergonomic Load Calculator that can be used to estimate the force needed to move loads in a variety of workplace environments and recommend ergonomic solutions to your material handling problems.
  • Administration modifications involve alterations to the work organization and/or workplace culture. While less expensive to implement, results are also less reliable in that they depend entirely on human compliance. Administrative modifications may include education and training in ergonomic procedures, restructuring job responsibilities to minimize repetitive tasks, worker/task rotation, increasing the frequency or duration of break periods for certain tasks, improving workers’ physical conditioning and developing oversight programs.
  • Work practice modifications include the development of ergonomic procedures for the performance of each individual task, worker training and oversight.

The initial investment in ergonomics may seem to be considerable, but the benefits — and long-term savings — far outweigh the costs and continue long after the initial investment is recouped.
