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.

Hazards in the Workplace

Many things located in your workplace; things that you use every single day without a second though, things as common as pallets, ladders, hand trucks can all prove to be dangerous if not used properly.  Many of the pieces of equipment that you use on a regular basis, the things that you come in contact with so often that you take their necessity for granted, can pose a serious health risk to you and others if they aren’t in good condition or if they aren’t properly used.

Regular inspections of all equipment should be made to ensure that everything is in good working condition, regular maintenance should be performed on any equipment that contains moving parts and you should ensure that all of your employees are educated on the proper use of the equipment.

The equipment that you use everyday needs to be: properly used by your employees, in good working condition and capable of handling the work that you are using it for.  Many workplace injuries can be avoided simply by the use of the right equipment for the task at hand.  The electric carts and lifts offered by DJ Products are easy to operate – your employees can be trained quickly to operate these lifts properly, safely and efficiently.  They are quiet – the rest of your employees won’t be distracted by excessive noise while DJ Product’s equipment is operating.  They are highly efficient and have long battery life – your employees won’t be stuck with an unfinished load of material in the middle of your warehouse due to the fact that their cart died.  All of these attributes will make your warehouse more efficient and much safer for all of your employees.

Safety should be a prime concern when you work in material handling – and safety starts with the right equipment for the job and properly trained employees.  You can make your operation as safe as possible and dramatically increase your company’s efficiency by using the right equipment for the job.

Give Your Operation a Lift with Material Handling Tugs

Are you still utilizing pallet jacks and forklifts to transport loads in your warehouse or plant? Investing in power material handling tugs from DJ Products can pay long-term dividends thanks to increased efficiency and fewer work-related injuries.

With space often at a premium, the smaller, more manageable tugs offer quicker movement of material from place to place. Weight of the load is distributed over the drive wheels, increasing traction that allows for easy transport of even the heaviest materials. This also means that a single person can handle loads that usually require two or more people.

According to the Bureau of Labor and Statistics, a full 50 percent of work-related musculoskeletal disorders are back injuries. Each incident results in anywhere from seven to 21 days off the job. Material handling tugs provide an ease of operation that sharply reduces the danger of injury. They also include ergonomically designed features such as variable speed twist grips, eliminating factors that cause repetitive stress.

Safety is a prime standard in the design of our tugs. Emergency stop switches let operators quickly shut down if necessary, preventing injury as well as damage. Your employees will work with a greater sense of confidence, resulting in an overall boost in morale.

Our DJ Products line of material handling tugs includes the PartsCaddy and CarpetCaddy that can accommodate unusually shaped or oversized loads. No matter what your needs, you’ll find a style that fits. Our Sales Engineers are ready to help you find your perfect solution at 800-686-2651.

Implementing a Forklift-Free Program

Forklift trucks are expensive to maintain and are a significant source of worker injuries and even deaths each year. The high cost of using forklifts in manufacturing, warehousing and logistics environments is pushing an increasing number of businesses to go forklift-free (see our June 11 post). Going forklift-free can reduce inventory and equipment needs, improve material flow and customer response, increase cycle efficiency and overall productivity, and decrease operating costs. At the same time a forklift-free work environment significantly improves plant safety; decreases liability concerns; and markedly decreases worker injuries and associated medical, insurance, disability and lost man-hour costs.

Implementing a forklift-free program can be challenging and will require a coordinated effort by top-level management, all affected departments, and suppliers, say John Neuman and Larry Tyler in American Machinist. They emphasize that success will require the ability to maintain “a big picture overview of the project as well as an understanding of how each department and suppliers, both internal and external, will be impacted.”

A successful transition to a forklift-free environment begins with a clarification of plan targets and goals and the identification of waste, ergonomic and safety threats. Neuman and Tyler suggest beginning by asking how operations and your supply chain will be impacted by a forklift-free system. Typical project leaders include manufacturing and industrial engineers and material logistics personnel. Input should be gathered from safety teams, production managers, line operators, tug drivers, market supply teams, your purchasing department and suppliers. Good communication, efficient information coordination, and clear assignment of responsibilities are important to success at this stage of the project, warn Neuman and Tyler.

Performing a trial run that physically traces each step of operation from the supplier to the receiving dock through assembly and back to the shipping dock allows the implementation team to uncover any potential problems before initiation. Role playing allows each individual who will participate in the new process to experience and try out the actual movements they will need to undertake in a forklift-free production. The suggestions gained from a physical dry run can provide valuable insight into operational, personnel and supplier issues that must be addressed before full implementation of a forklift-free system.

Obviously, implementing a forklift-free environment in an existing plant presents a significantly greater challenge than in a new or remodeled facility where changes can be incorporated in the planning phase. Neuman and Tyler warn that “existing plant constraints may make the best forklift-free strategy less than optimal.” Aisle widths, conveyor heights, set backs, line space, ceiling height and floor quality are among the challenges that may need to be overcome. Incremental conversion beginning with one or two work cells or a common assembly area may allow for greater success in brownfield operations. Despite the added challenges, positive results can be achieved in brownfield operations though initial cost and implementation time may be somewhat greater.

Functional Equipment doesn’t necessarily mean Basic Equipment

Many of the duties performed in a warehousing environment are repetitive, especially if much of the material distributed is similar.  Employees in the receiving department follow the appropriate procedure from unloading to stocking and the shipping department will follow their detailed procedure for pulling, stationing and prepping the materials to be picked up by the freight carrier.

This seemingly simple operation might lead people to believe that any old equipment can perform the job – all the employees are doing is moving materials from one spot to another right?  This assumption couldn’t be further from the truth though, the procedures followed in many warehouses and distribution centers follow a similar path – but if safe, reliable and properly designed equipment weren’t available, the business would never be able to keep up with the competition.

Some warehouses would probably be able to function for a very brief period with just the most rudimentary materials, like hand trucks and pallet jacks – provided that the material is to large or cumbersome to be handled manually.  There are probably some distribution centers that could squeak by for a brief period with outdated propane fueled forklifts that are prone to breakdown and require regular maintenance but operating in this fashion would certainly mean the most difficult road for the employees and the biggest risk of not being capable of accurately fulfilling orders.

The ergonomically designed and battery powered lifts from DJ Products are the solution to any material handling problem plaguing a warehouse or distribution center.  These lifts and carts are easy to operate, quiet, safe and the most reliable available.  These days, just keeping up with the competition in the distribution industry may not be enough to survive – you have to give your employees every edge to be able to fulfill orders as quickly and accurately as possible.  The edge often begins with the equipment used to get the job done, that’s why many warehouses and distribution centers are turning to the lifts and carts produced by DJ Products for their material handling needs.

The Future Is Now!

If you have kids, you’ve probably seen trailers for the new Disney-Pixar animated film WALL-E. Robots like WALL-E and his cohorts represent the wave of the future in material handling, though let’s hope they get the kinks worked out before they start installation. Can you imagine the chaos if a bunch of inept robots was allowed to run amuck on your plant floor? Life, after all, is not a movie. The hero almost never arrives to save the day in the final seconds of a plant emergency!

Robot prototypes that allow us to glimpse and plan for the future of material handling are already on the market. British tech firm RTS Flexible Solutions has introduced a 3-D vision-based robot automation system that can grip complex shapes and profiles, pick at variable heights and even perform some inspection and defect rejection actions.

“Advances in technology mean we can deliver applications which have been difficult for conventional 2D technology,” commented RTS managing director David Bradford. While 2D vision-guided robotic automaton works on grayscale, color or line-scanning vision systems, the new 3D system can process on X, Y and Z coordinates. For the first time this allows a robotic application to accurately gauge height, depth and surface contours, opening new possibilities for material management. 

It will be a while before robotic applications can effectively perform many material handling functions, but that day can already be glimpsed on the horizon. Computer software and management skills are more apt to define material handling workers of the future. It’s going to be a whole new ball game!

More Companies Going Forklift-Free

An increasing number of companies, particularly in the manufacturing, warehousing and logistics industries, are moving toward a forklift-free environment. Safety concerns and maintenance costs are the primary factors driving this major change in material handling application.

According to a recent study by the Hyster Company, a major manufacturer of forklift trucks, only 6% of end-users know their real forklift maintenance costs and few have implemented programs to reduce those costs. Over the 20-year life of a forklift, 80% of the total costs are operating expenses. Ownership accounts for only 20% of a forklift’s total cost. The Hyster study estimates that American businesses waste more than $1 billion per year in unnecessary material handling operating costs.

Far more expensive are the human loss and liability costs directly tied to forklift injuries each year. Each year, nearly 100 U.S. workers are killed in forklift accidents and another 20,000 seriously injured. Forklift overturns cause 25% of forklift-related deaths. Medical expenses, insurance costs, workmen’s compensation and lost man-hours associated with forklift accidents cost American businesses millions of dollars each year.

According to John Neuman and Larry Tyler, writing in American Machinist, a forklift-free program can have multiple benefits, including:

  • reduced inventory,
  • improved material flow,
  • reduced line-side handling equipment,
  • reduced floor space,
  • increased cycle efficiency,
  • increased floor coordination,
  • increased stocking efficiency, and
  • decreased operating costs.

On the human side, a forklift-free environment improves investor, worker and public perception of a company’s attention to safety. It improves worker ergonomics, efficiency and production and decreases expensive lost man-hours, medical, insurance and liability costs.

New Retrofit Cart Kit Removes Strain From Common Tasks

DJ Products has introduced a revolutionary new motorized retrofit cart kit that takes the pain and strain out of common tasks performed by many workers in a broad section of U.S. jobs. Designed to be mounted to almost any cart, this new retrofit kit can increase usefulness, flexibility, efficiency and worker safety in a wide variety of environments, including applications in hospitality and resort, hospital and healthcare, food service, retail, distribution and warehousing, vending, casino, banking and a host of other industries.

Designed to enhance and improve the capacity and flexibility of your cart investment, DJ Products’ retrofit cart kit is ergonomically designed and motorized to eliminate the musculoskeletal strain placed on workers when manually maneuvering heavy carts through the work environment. As America’s workforce ages, the risk of bodily injury increases as workers struggle to push and pull heavy carts from place to place and into position for use. Particularly common are back and muscle injuries that usually require expensive, long-term treatment and account for considerable lost man-hours.  A single back injury can cost a business $26,000 in time lost.

Employers who have installed DJ Products’ retrofit powered cart kit on their carts have reported a significant decrease in work-related injuries and employee turnover. Hand-in-hand has come improvement in employee efficiency and productivity. Employees have also expressed increased satisfaction with their jobs, a common phenomenon when employers act in their workers’ best interest to safeguard health and safety.

Able to power carts up to 4,000 pounds, DJ Products’ motorized retrofit cart kit is equipped with ergonomically-designed, variable-speed twist grips that allow forward and backward motion at speeds up to 3.2 mph. The motorized kit can move carts over a wide variety of surfaces, including carpet, tile, marble, cement and asphalt. Powered by two heavy-duty 12-volt batteries, the 24-volt motor in DJ Products’ retrofit cart kit is powerful enough to perform for an entire shift without recharging. Customizable to any application or environment, the DJ Products retrofit cart kit can be field installed by the customer or DJ Products can provide onsite installation.

Always be Prepared

The Occupational Safety and Health Administration, also known simply as OSHA, is responsible for setting and enforcing the standards of safety in the workplace.  The main goal of OSHA is to reduce on the job injuries and fatalities by assuring that workers are performing their jobs in the safest environments possible.  Since it’s inception at the end of 1970, OSHA has dramatically reduced the incidents of accidents in the workplace and they continue to inspect facilities and enforce their policies in an effort to make working people even safer.

Between the federal and state run divisions of OSHA, more than 100,000 facilities are inspected each year and those not meeting the standards could receive heavy fines depending upon their infractions.  The number one violation cited by OSHA has to do with forklift operation.  This should serve as a warning to all warehouse and distribution environments that if they are operating outdated and unreliable equipment or if they haven’t properly trained their employees on correct usage procedures of equipment that they could suffer citations and heavy fines from OSHA.

There is much more at stake though than a fine, operating your facility with under trained employees or old and unreliable equipment could make your facility run poorly, inefficiently and it can put the health of your employees in jeopardy.  In order to have the safest facility possible you need to be running equipment that was designed for the tasks that your employees perform and you need to properly train your workers to operate that equipment.

Electric lifts and carts from DJ Products are designed with safety and performance in mind – they are easy to operate, ergonomically designed and can last for an entire shift on a single charge.  Properly using the right equipment is the first step to a safer, more effective and more efficient workplace – and it will eliminate the most cited infraction of the standards set by OSHA and keep you one step closer to compliance.

Sustainability Takes “Green” to Next Level

Everyone is “going green” these days. Concern for the environment sparked “green” businesses, but skyrocketing fuel prices have ignited those efforts, pushing environmental practices ever more quickly toward sustainability.

What is sustainability? Sustainability takes environmentally-friendly practices to the next level. It improves upon the protection and husbandry of the world’s natural resources by utilizing processes that reclaim and reuse the products and byproducts of industry. Production comes full-circle: resources are used to create products which are then used and, at the end of their life cycle, recovered and reused to create new products.  The ultimate goal of sustainability is to complete the cycle without creating unusable byproducts or waste and without polluting the environment.

Supply Chain Sustainability and Green Sustainable Supply Chain are the coming watchwords in the material handling and logistics industries, said Patrick Penfield of Syracuse University’s Whitman School of Management in a 2007 article for On the MHove, a MHIA publication. Growing concern over environmental pollution and dwindling natural resources are driving the push for sustainability.  “Humankind has inherited a 3.8 billion per year store of natural capital. At present rates of use and degradation, there will be little left by the end of the next century,” authors of the book Natural Capitalism warned in 1999. Less than a decade later, scientists are concerned that the crisis point could be reached far sooner.

Despite the Bush administration’s failure to embrace global environmental efforts (and there are many valid arguments on both sides of that issue), European legislation restricting pollution and hazardous substances presage the future. Experts predict that the world will be unable to support its populace if the global community — including the U.S., China, Brazil, India and developing countries around the world — does not embrace environmental protection and work quickly to implement sustainable industry.
