Notable Words

By Kim A. Stelson, Director, Center for Compact and Efficient Fluid Power (CCEFP)

Sustaining a National Research Program for Fluid Power

I

n my last Notable Works column two years ago, I highlighted the energysaving potential of fluid power. The data for that column came from a draft of a Department of Energy (DOE) report, “Estimating the Impact (Energy, Emissions, and Economics) of the U.S. Fluid Power Industry.” The report has recently been officially released. You can read it at www.osti.gov/servlets/purl/1061537/. The delay in the release was caused by skepticism within the DOE. The numbers were just too good to believe.

But the numbers are accurate. Fluid power consumes 2.1% to 3.0% of all of our energy with an average efficiency of 22%. By adopting best practices and developing new technology, the efficiency of fluid power would dramatically increase efficiency, substantially reduce energy use, and curb emissions. Annual U.S. sales of fluid power exceed $17.7B for components and $226B for systems that use those components, presaging the large economic impact of a program to promote more efficient fluid power.

As impressive as it is, since it confines itself to existing applications, the DOE report underestimates the impact of more efficient fluid power. The rapidly developing field of hydraulic hybrids illustrates this underestimation. Hydraulic hybrids for off-road applications, such as excavators, would be an existing application included in the DOE study, while hydraulic hybrids for on-road applications, such as delivery vans, would be a new application not considered in the DOE study.

Considerable progress has been made in both off-road and on-road hydraulic hybrids. As just two examples in the last year, Caterpillar announced the first hydraulic hybrid excavator and Parker-Hannifin announced the creation of a new division to produce hydraulic hybrid systems. Both of these developments promise dramatic efficiency improvements and expanded employment and economic development.

The efforts to create more efficient fluid power are supported by the activities of the Center for Compact and Efficient Fluid Power (CCEFP). CCEFP is a research and educational organization with seven university and more than 50 industry members.

Our mission is to transform the way that fluid power is researched, applied, and taught. We do this by developing fluid power that is efficient, compact, and effective. Efficient fluid power will save energy; compact fluid power will be smaller and lighter; and effective fluid power will be quiet, clean, safe, and easy to use.

The CCEFP is in its seventh year, and the impact on fluid power is being broadly felt. Before CCEFP, university research in fluid power in the United States was confined to a few isolated research groups. It has now grown to an $8-million coordinated effort with funding from government, industry, and universities. Our researchers work closely with industry and employ a systems approach to set research priorities.

We are currently supporting 21 research projects that are demonstrated on four test beds.

The numbers show the impact of CCEFP on fluid power workforce development. The Center currently has 48 faculty and staff researchers, 81 graduate students, and 63 undergraduate researchers. Since its inception, 104 bachelors, 80 masters, and 28 doctoral students have graduated. A recent survey showed that 61% of CCEFP graduates enter the fluid power field. Of the 70 students who participated in the 2012 NFPA Workforce Development Summit, 56 were from the seven CCEFP universities.

Center researchers have also been active in publishing research Our mission is and patenting inventions. To date, research has resulted in 78 pubto transform lications in technical journals and 248 publications in conference the way that proceedings. Forty-three (43) inventions have been disclosed, 24 patent applications filed, two patents awarded, and two licenses fluid power is issued to industry. researched, CCEFP is in the seventh year of a ten-year program funded by applied, and the National Science Foundation. In the next few years, we will be making a transition to other funding sources. Of course, we taught. will continue to receive dues from our industry members, but this support covers less than 10% of our operations. And we will continue to aggressively pursue funding for individual projects from government and industry sources. But to really have a continuing impact, CCEFP must obtain a large government grant. To make CCEFP sustainable, we are actively pursuing large government grants from two sources: the Department of Energy (DOE) and the NNMI (National Network for Manufacturing Innovation). The investment in fluid power from these programs is justified by the large potential for energy savings and economic development documented in the DOE report.

Industry support of CCEFP is important for its success. If you are an industry member of CCEFP, I would like to personally thank you for your support. If you are not a member, I hope you will consider joining us. Information on industry membership can be found at www.ccefp. org/industry. The many benefits of industry membership are detailed there.

Global Manufacturing Update

By Chad Moutray, Chief Economist, National Association of Manufacturers

(February 8, 2013) – The new year has begun with some stronger economic data worldwide.

While persistent challenges remain—most notably in Europe, but also some lingering fiscal worries in the United States—the overriding trend has been for some modest gains in new

orders, production, and hiring in a number of key markets for the U.S.-manufactured goods.

Seven of the top 10 export markets have economies that are expanding, and there were signs that the pace of the contraction in Europe and Japan eased a little. The Purchasing Managers’

Index (PMI) for the Eurozone rose from 46.1 in December to 47.9 in January. The largest improvements in manufacturing, however, were in Asia, where the pace of industrial production has picked up some steam in the past few months. This news spreads beyond China and into other parts of Asia, as well.

Our largest trading partners are Canada and Mexico. Much like the United States, Canada’s economy appears to have stalled of late. This is not surprising given the closeness of our two nations in terms of commerce. U.S. frustrations with the fiscal cliff and upcoming federal budgetary battles tend to resonate beyond our borders, with the effects most felt in Canada. Real GDP is expected to grow around 2% this year in Canada, mirroring the forecasts for the United States and essentially repeating last year’s rate. Reflecting these trends, Canada’s PMI suggested very slow growth in January, unchanged from December.

Mexico’s economy, meanwhile, decelerated throughout much of the second half of 2012, both leading up to and after its presidential elections. Some of the slowdown involved a waitand-see approach as business leaders assessed the impact of possible new policies coming from the new presidential administration. Industrial production and PMI values tend to reflect this easing, but Mexican real GDP is still expected to grow 3.8% in 2013, which is a solid number.

Even with the progress in foreign markets, the most recent international trade figures were a bit of a surprise. The U.S. trade deficit declined sharply from $48.6 billion in November to $38.5 billion in December. Changes in the petroleum balance partially contributed to the decline, but in general, it was a healthy increase in goods exports corresponding with a decrease in goods imports. For the year as a whole, U.S.-manufactured goods exports rose 4.9% in 2012 at the non-seasonally adjusted rate, well below the 15% rate necessary for the United States to double exports by 2015. While we were on pace for that in 2011, a number of headwinds globally— including a recession in Europe and slowdowns elsewhere—eased the growth of new export sales significantly in 2012, frustrating manufacturers in the United States. Perhaps the improvements noted in this document more recently will bode well for better export figures in 2013. * Excerpt reprinted with permission. For the full report, visit www.nam.org.

Optimizing Pulse Dust Filters

H

igh flow-short duration pulses caused by compressed air-powered dust filter cleaning can cause excessive pressure differentials in a compressed air system and affect pressure-sensitive equipment in close proximity to these devices.

These filters are located in many agricultural facilities to protect against environmental pollution caused by powder and dust being released from the top of storage silos and process exhaust. Students of Compressed Air Challenge (CAC)’s Fundamentals of Compressed Air Sys6 cf per pulse tems seminar learn of an innovative way to prevent = these pulses from causing trouble in a system. > 1,000 scfm

Fig. 1 shows a typical filter housing arrangement where a bank of blast valves fed by a manifold, which is usually an oversized piece of pipe, is situated on the outside of the filter bank enclosure. To keep the filter elements clean, a control system opens each valve one by one in a timed sequence, causing a blast of compressed air to be released. The force of this blast shocks the filter elements and knocks out the entrained dust, renewing the element for further operation. Each blast lasts between one-tenth and one-quarter of a second, and when it occurs, a very high flow passes through the blast valves. In the case of Fig. 1, the supply lines, filter, and regulator must pass about 1,000 cfm of air for onetenth of a second for each pulse.

In this particular case, the supply line was one inch in size, and when the pulse passed through it, a very high-pressure differential developed, which starved the blast of the compressed air required for proper cleaning force. The rush of air feeding the blast also robbed nearby piping of compressed air, causing a large fluctuation in air pressure.

Fig. 2 shows the pressure falling from above 90 psi to as low as 60 psi during each pulse.

Due to the low pressure, the filter elements were not being cleaned properly. A solution to this might have been to increase the pulse duration and frequency, and crank up the pressure, but this would have consumed extra quantities of expensive compressed air, increasing the cost of operation signifi-

cantly and likely not adequately solving the issue.

To solve the problem, some small local storage receiver capacity (60 gallons) was installed plus a check valve and a needle valve. The check valve prevents the compressed air stored in the local receiver from flowing back into the plant to feed some other air demand. The needle

valve slows the flow of air so that large pulses do not flow though the small supply line, filter, and regulator. The needle valve is set so that the compressed air slowly fills the local receiver, which reaches its final pressure just as the next blast of compressed air is called for by the blast controller. This acts to average the flow in the supply lines to a more manageable 36 cfm, which reduces the high-pressure differentials.

This is just one example of several “tricks of the trade� discussed in the CAC Fundamentals training. Many more improvement measures are mentioned in the course material and in the accompanying Best Practices for Compressed Air Systems Manual that each course participant receives. CAC training has been scheduled in numerous areas of the country and may be happening at a location near you.

A prominent researcher as well as a caring doctor, Dr. Kamen authored more than 300 manuscripts and was the editor-in-chief of The Journal of Pediatric Hematology Oncology.

Dr. Kamen received his M.D. and Ph.D. from Case Western Reserve University and served his internship/residency and fellowship in pediatrics and pediatric hematology-oncology and pharmacology at Yale University.

“Our FIRST scholarship recipients are outstanding contributors to the colleges and universities they attend, and the corporations where they intern, and they have a wonderful track record at their employers,” noted Walt Havenstein, chairman, FIRST Board of Directors. “As FIRSTAlums, they carry the message that the pursuit of a STEM (Science, Technology, Engineering, and Math) foundation is paramount to the country’s workforce development, as well as their own long-term career.”

Dr. Kamen was known by his colleagues as a brilliant scholar, compassionate physician, dedicated mentor, and gentle man with unfettered enthusiasm for learning, teaching, talking science, and challenging the mainstream with his out-of-the-box thinking for the betterment of patient care.

The total number of scholarship dollars available to college-bound FIRST participants has grown to over $16 million with the addition of the new fund. Eleven (11) new college/ university/corporate providers joined the FIRST scholarship program in 2012.

A total of 158 colleges, universities, corporations, associations, and funds support the FIRST mission by generously donating meritbased scholarship opportunities to eligible students who want to take their FIRST experience to the next level. Last year, nearly one in three applicants was offered a FIRST scholarship, and 25% of the recipients were female.

Any FIRST participant in the FIRST® Robotics Competition (FRC®), FIRST® Tech Challenge (FTC®), or FIRST® LEGO® League (FLL®) who has completed a minimum of one year in a FIRST program is eligible to apply for the Dr. Bart Kamen FIRST Scholarship Fund.

(The 2013 deadline for applications was February 13, 2013.)

Internships at Autodesk Lead to Collaboration Tool for Teams Over the summer of 2012, eight high school student interns from different FIRST Robotics Competition (FRC) teams in Oregon worked

together at Autodesk. The group took 10% of their time to create Built by Design (BXD), a tool for FRC teams, designed to eliminate the common problem of having only one to two CAD designers on a team. The goal of BXD is to lessen the learning curve of CAD and give teams an alternative workflow for the brainstorming process. Ideally, teams will be able to fully design their robot within the first week of build session.

To implement this program, the interns created an easy-to-use website that is available to new

users and veteran users alike. Feature include • Users can view 15 short tutorials covering the entire design process: brainstorming, digital prototyping with Fusion, and detailed CAD using Inventor.

• Users can share, download, and review designs.

• Users can easily download Autodesk Inventor and Fusion.

• Users can accelerate designs with the new 2012 FRC CAD library.

Are You As Well Rounded As You Think You Are?

f you are one of those individuals who are convinced that you know everything there is to know about fluid power and that there is nothing more to learn, you can stop reading now and go find something else to do. If you want to learn more about the industry, make more money, or be of greater value to your employer but don’t think you should have to expend any time, effort, or money of your own to do so, you might want to get going now so you can car pool with the know-it-all. And lastly, if you are a business owner or manager who just doesn’t think it is worth investing in training or certification for your employees, maybe you can catch up with the other two and complain about the weather together. If you are still reading, great! I hope to share some thoughts that might cause you to view things in a different way.

All Certification Paths Lead to Professionalism

When I took my first job at a distributor in 1986, it never really occurred to me that fluid power would be—even could be—my career for some 26 years (so far). I remember well those early days of constantly tailing my boss and asking all sorts of dumb questions (and yes, some were really dumb). At the time, I was not motivated by any reason other than to convince him to pay me more money. I think partially from the frustration of dealing with me and maybe in some appreciation that at least I was trying, he gave me a copy of Womack Industrial Fluid Power, Volume 1. Neither of us realized it at the time, but with that simple gesture and a little encouragement, he set me on the path that would become my lifelong profession and in as much as an occupation can be (other than guitar-slinging rock star or power forward in the NBA), my passion. From that, I made up my mind then that I wanted to learn as much about every aspect of fluid power as possible.

Throughout the course of my career, I have encountered many people with varying skills from whom I have learned, by whom I have been influenced, and around whom I have modeled myself. Not just in copying their way of doing things, but also in emulating their methods of thinking and how to approach a task. Several times along the way, I heard of individuals being referred to as the “expert” or “guru.”

After getting to know a number of these people, I began to ask myself, what exactly is an expert? Is it the counter person who has every part number in the hose and fitting catalog memorized? Is it the mechanic who can tear down, rebuild, and test a pump without having to refer to the repair manual or parts list? Is it the service tech, armed with only a couple of gauges and a flow meter, who can diagnose a seriously malfunctioning machine and get it operational again when others have failed? Is it the engineer who can design a system using all of the latest technology that will all but stand on its head? All of these individuals are certainly authorities in their own right, but do any of these skills singularly constitute being a true fluid power expert? Well, yes and no…and here is what I mean.

In any piece of machinery—mobile or industrial—there is a life cycle. I do not mean its life span, although that is true, too, but a specific series of sequential events that define how it all comes together. More often than not, this sequence starts with the equipment salesperson and the customer defining exactly what is required for the machine functionality and serviceability. Sometimes, these persons may not be fully appreciative of the nuances of fluid power. From there, machine

design concepts move to the engineering and component selection phase and continue on through manufacture, factory testing, in some cases installation and commissioning, operation, maintenance, and eventually, repair. Anywhere along the way, any shortcoming in the design or manufacturing that impacts any of the others may require modification or repair to realize a more robust machine design. In a large OEM or service/repair setting, these tasks are likely to be carried out by different individuals with varying skill sets and degrees of competence, each as critical to the success of the project as any other.

In smaller, more specialized companies, a single individual may have the responsibility for supporting several or even all of these activities.

In today’s highly competitive manufacturing and service environment, machine and equipment uptime is critical and more often than not, a determinate to the success and survivability of a company.

Downtime is the death knell of profitability. Perhaps the most important persons in this metric are the mechanics and technicians. The wide range of skills required from the individual to keep a machine operational or to get it running after a breakdown is significant. This person must have an understanding of mechanics, hydraulics, pneumatics, and increasingly, electric and electronic controls. That is a tall order by any standard.

Some of the best engineers with whom I have worked with are those who have a significant background or started their careers in troubleshooting and repair. They have seen what works, what doesn’t, and what to do about it. They have a keen understanding of what it means to design and package an energy efficient and safe system for minimal maintenance, reduced downtime, and repair with the fewest tools.

They understand firsthand the need for and the value of proper and thorough documentation.

In other words, the engineer designs, the test technician tests and troubleshoots, and the mechanic fixes, and all of these skill sets are critical. In the context of the overall success of the project, none is exclusive or more important than the other. Experts must be knowledgeable in the many aspects of fluid power: hydraulic, pneumatic, as well as basic electric and electronic controls.

To boil it all down, it doesn’t matter if you have been in the industry six months or thirty years, to advance your career and become that well-rounded fluid power “expert”, you must have some skin in the game.

Becoming a well-rounded fluid power expert does not end at a particular destination; it is a continuing, career-long journey. It requires the self-challenge to constantly seek out the opportunity to learn by engaging others with more or different knowledge and skills than your own. It demands stepping outside of your comfort zone and taking on the challenges that others may avoid. It involves extra time and effort that perhaps you would rather spend doing something else. One must read from textbooks, fluid power periodicals, and as boring as it sounds, component manufacturers' catalogs for no other reason than to gain knowledge of the types of hydraulic and pneumatic hardware in the marketplace, how they work, and how they do not. To gain additional knowledge, one should consider taking a community college course or technical seminar in a discipline where his or her skills are weak. off-highway directory 2013

Certification Challenge

To boil it all down, it doesn’t matter if you have been in the industry six months or thirty years.

To advance your career and become that wellrounded fluid power “expert,” you must have some skin in the game.

Okay, I am guessing by now that I am preaching to at least some of the choir, but you may ask, what does this all have to do with me? What

does this have to do with certification? To keep pace with the broad and ever-changing needs of industry, the International Fluid Power Society provides many specific and complementary certifications to demonstrate core and advanced competencies. And though some of the content from one certification to another is necessarily overlapping, each offering is targeted to meet the particular needs of the individual and to establish his or her qualifications. Getting certified and holding multiple certifications demonstrates that you take your career seriously. Simply put, the IFPS is there for you and the advancement

of your career and can be the key component to increasing your worth to your employer.

So, what exactly is a fluid power expert? It is the individual who can satisfactorily address the particular need at that moment and one who also has a demonstrable, broad base of knowledge. If you are well rounded in multiple aspects of fluid power, prove it. Take the time and make the effort to get certified in all of those areas.

Then that expert can and will be you.

Lastly, are you an employer or manager asking yourself, “What can I get out of certification?” You can assure your customers that your employees possess an industry-wide accepted level of competence and that your mechanics, technicians, and engineers have the skills necessary to perform their tasks confidently, efficiently, reliably, and safely. It shows you encourage employee pride and are willing to invest in the development of their careers. Tell the world that as a business owner or manager, you care about the image your company and employees put forth and how it reflects on the larger fluid power, manufacturing, and service communities.

So now you might be thinking, “Okay, but why should I spend all of this money in training and certifying my employees and risk them leaving and going to the competition?” Well, For more I have some bad information on news for you. When the many IFPS it comes to the talcertification ent pool, the fluid offerings, visit power industry is in www.ifps.org a crisis. The number of individuals coming into and staying in the industry compared with those leaving or retiring is strikingly disproportionate. If you don’t invest in the development of your employees, including in training and certification, you are inadvertently promoting the industry’s—and maybe even your own company’s—demise. At some point, it will not be a matter of if you lose that employee but just a matter of when.

In the words of the late-and-great motivational speaker and sales coach, Zig Ziglar: “The only thing worse than training an employee and having them leave is not training and having them stay.”

On the subject of employee training and development, no truer words have ever been spoken.

New Problem

Cylinders are 2" x 10" x 1" Supply Pressure is 100 PSI Question: What is the highest pressure that the gages A & B will see without any shock loading or any inefficiency? previous Problem

A: B:

Solution: Have you heard of the saying, “When in doubt, meter out”? Be careful. These two problems are a bit tricky, and most individuals don’t realize or even think about the intensification of pressure when using a meter-out circuit.

Problem A: Calculate total force to extend piston: F = PA & A = D² x 0.7854 A = 2² x 0.7854 = 3.14 in²; Using F = PA F = 100 x 3.14 or 314 lb.

Now subtract the 250-pound mechanical load from 314-pound pneumatic capability = 314 – 250 = 64 lb.

This remaining load is held back with the rod end area of the cylinder. Effective rod end area (EREA) = 3.14- 0.7854 = 2.36 in² Using F= PA 64 / 2.36 = 27 psi on extension Note: On retraction, the gauge will go to 100 psi when the cylinder is fully retracted.

Answers for A: 27 psi on extension and 100 psi on retraction

Winner: Ronald Arreola CFPS Hydraforce, Inc. Lincolnshire, IL

Answered Correctly: Harold Lawson CFPPS, Air, Inc. Franklin, MA

Problem B: Here we have an intensification problem. The extending force from the mechanical load is 250 lb. The extending force from the air pressure is again 314 lb. Together that is 564 lb pulling down supported by the EREA of 2.36 in² (F=PA) or 239 psi. That is 564 / 2.36 = 239.

On retraction, the gauge read about 80 psi without inefficiency until fully retracted and then read 100-psi system pressure.

Answer of B: 239 psi on extension and 100 psi on retraction. NOTE: It would actually take about 106+ psi to lift the load, but system pressure is only 100 psi.

Best answers are 100 psi for A and 239 psi for B. This is why manufacturers design and rate their valves higher than normal system pressure.

An Introduction to Hydro-Mechanical Transmissions

By Mike Cronin, Caterpillar, Inc.

uel cost and the fuel-saving characteristics of continuously variable transmissions (CVTs) have increased the pressure to provide CVT capability to larger and larger off-road machines. Hydro-mechanical transmission architecture allows smaller hydraulic components to provide cost-effective CVT functionality to larger machines. As a result, the number of hydro-mechanical transmissions in the marketplace is growing.

A hydro-mechanical transmission schematic is conceptually simple with two parallel power paths (Fig. 1). The hydraulic path is made up of a pump and motor referred to here as a “variator.” The mechanical path is typically a shaft with maybe a gear or two. These paths are interconnected with ordinary mechanical transmission components such as gears, shafts, clutches, and at least one planetary. There are a very large number of interconnection possibilities. In a given design, it is the details of these interconnections that constitute the bulk of the intellectual property and the suitability to the target machine application.

Hydro-mechanical transmissions have been available in agricultural tractors for a long time.

They are either standard or offered as an option (Fig. 2).

Hydro-mechanical transmissions have not generally been available in earthmoving equipment until now. The wheel-loader segment is

• Third is number of ranges or modes. This is the number of different mechanical interconnections made between the mechanical and hydraulic paths by engaging and disengaging any clutches in the gear systems. Note that the type of coupling is not necessarily the same for each range or mode.

Consider the engine fuel map shown in Fig. 4.

The vertical axis is engine power and the horizontal axis is engine speed. The peak of each contour indicates the maximum engine power for that fuel rate. The locus of these peaks defines the best engine speed for minimum fuel consumption.

Consider the powertrain described in Fig. 5.

The plot in the lower part of the figure indicates that for any given ground speed, there are only one or two engine speeds possible. It is unlikely

thought to benefit the most from a CVT, and that is where the latest offerings can be found. The examples in Fig. 3 have been announced and are available now or will be shortly.

Three things differentiate given designs: • First is the construction of the variator and its location, for example variable-displacement swashplate pump, fixed-displacement bent axis motor, internally mounted.

• Second is the type of coupling. Common terms are input coupled, output coupled, and compound split. While the particulars of this nomenclature are well beyond the scope of this article, it generally describes whether or not the transmissions input or output shaft is directly connected through a gear ratio to one of the variator shafts. In the case of compound split, neither variator shaft is directly connected.

that one of these speeds falls on the minimum fuel consumption line of Fig. 4. Furthermore, anticipated load changes, particularly if there are any difficulties in changing ratio, may lead an operator to choose a higher engine speed (higher fuel consumption) and/or slower ground speed (slower cycle time).

Consider the powertrain in Fig. 6. The plot in the lower part of the figure indicates that for a given ground speed, nearly any engine speed is possible and therefore can match the minimum fuel consumption engine speed shown in Fig. 4.

The engine speed lines from the plot in Fig. 5 are included for reference. Because modern hydromechanical CVTs change ratio so well, there are few if any issues with load changes like there may be with discrete step transmissions.

While the information in this article may not prepare you to design a hydro-mechanical transmission, it will enable you to more readily recognize them and their potential benefits.

It's Never Too Late To Be Safe

By Carl and Deb Potter, Potter and Associates

their personal targets for zero-injury days, for conducting pre-job briefings or inspections, attending safety meetings, or any other targets that apply to your company. Consider this: most employees are going to target zero injuries for every workday, and regardless of the number of employees in the organization, the approach will work.

A team of employees can share their individual goals and develop a team aggregate goal. This will help them be accountable to one another and to look out for each other. The key is to keep the goals personal and to have the employees set the goals themselves. Your organization may have a specific area of focus to reduce injuries; for instance, you may be striving to reduce hand injuries or slips, trips, and falls. If so, engage individual employees and workgroups by ask-

he new year is often a time when people reset their goals, start fresh, begin a new chapter, or take any number of other actions to start over. We call it “resetting the counters.” Many organizations make the new year a time to set forth company-wide safety goals. Some companies set a goal of “X” incidents, signifying a reduction in OSHAreportable injuries over the previous year. Others set goals of “zero injuries” or “zero incidents.”

These goals are great to motivate people to work safely, yet sometimes the goals seem too lofty for employees.

T

A Personal Goal for Safety Another way to approach safety goals is to ask employees to set their own personal targets.

Within their workgroup, employees can share

As you consider the goal that you, other individuals, and work teams set, determine what it will take to be successful. If your goal is to perform a pre-job briefing for each job, what will you need to accomplish that goal?

Maybe you need to take steps to ensure that a pre-job checklist or form is readily accessible and easy to use. Perhaps you or others need some training on how to conduct the briefings. If your goal is to make each job injury-free, you may need to work to understand the common hazards associated with each task and how to control them. Take time when you set your goal to understand what might get in the way of success and what you can do to overcome the barrier.

Also, take time to understand what you are already doing that will give you the momentum to succeed.

The Best Goal of All The very best safety goal a person or work team can adopt is “Nobody Gets Hurt.” This goal can be the target for every year, every day, and every job. It’s a goal that you may want to use for yourself or to suggest to your team. When you think about it, the goal can help you look out for yourself and others, and is a way to encourage others to look out for you. And this goal can be set any time of the year. You don’t have to wait for a new year to roll around. There is no better time than now to set this goal as your own.
