From the desK of the PRESIDENT

I realize that we are well into the New Year already however, I felt compelled to state it. As 2018 begins we add yet another year of success for the RETA Organization. 2017 was an amazing year for the Association and 2018 is gearing up to be the same, if not better. At the time of this article, the membership total is at 6,152. This is an amazing accomplishment and one to be recognized. The African Proverb – It Takes a Village to Raise a Child — is a perfect reflection of our organization. It takes the work of many to continue the growth of this great Association. It appears that winter has enveloped most of the United States. Here in the North East we have had several snow storms and temperatures well below freezing for extended periods of time. Lots of “FREE” cooling going on out there. If your work has you outside in these conditions please be safe and wear the appropriate clothing, hypothermia is no joke. Best regards, ~ Eric Girven, CARO, CIRO, RAI President, National Board of Directors Happy NEW YEAR

Mechanics/Technicians Apprenticeship Program

Refrigerating Engineers & Technicians Association worked alongside the Ammonia Refrigeration Foundation, International Institute of Ammonia Refrigeration, Global Cold Chain Alliance, Lanier Technical College- Technical College System of Georgia, and FASTPORT to develop a new and exciting apprenticeship program for Refrigeration Mechanics/Technicians. What is an Apprenticeship Program? Apprenticeship is a collaboration among business, industry and government organizations resulting in a skilled trade. Apprentices learn the aspects of a highly skilled occupation through on-the-job training and related instruction, while under the supervision of a journey-level craft person or trade professional. At the end of the program, the apprentice receives a certificate of completion and achieves journey worker status. Apprenticeship training requires a wide and diverse range of skills and knowledge, as well as maturity, commitment and sound judgment. Apprenticeship can yield a life- long rewarding CAREER! The U.S. Department of Labor states that registered apprenticeship training

is distinguished from other types of workplace training by several factors: (1) participants who are newly hired (or already employed) earn wages from employers during training; (2) programs must meet national standards for registration with the U.S. Department of Labor (or federally- recognized State Apprenticeship Agencies); (3) programs provide on-the-job learning and job-related technical instruction; (4) on-the-job learning is conducted in the work setting under the direction of one or more of the employer’s personnel; and (5) training results in an industry- recognized credential. “There’s this constant balance that goes on between the definition of a good job and our understanding of a truly valuable education. Not all knowledge comes from college, but not all skills come from degrees.” – Mike Rowe, CNNs Mike Rowe: Michigan Must Change Perceptions of Skilled Trades If you are interested in implementing an apprenticeship program, please contact Dave Harrison, Executive Director of National Apprenticeship at FASTPORT, at 479-231-9666 or dave.harrison@fastport.com.

“Safer” Refrigerants by William Lape

safeguards are proper system design and installation, allocation of sufficient resources for proper operation and maintenance of the system, and proper training in safe system operation, system maintenance, and leak response. This includes proper training in a facility’s emergency action plan, not only for employees, but also for visitors. In an industrial setting, facilities always try to educate their visitors on the emergency action plan. What about non-industrial facilities? Do these facilities explain to visitors what the facility alarms are and what to do when they go off, or is the expectation that they will read the sign next to the alarm (if there is one) and do what it says? When training is insufficient to the point that someone gets burned trying to siphon an ammonia-water mixture by mouth (www. technicalsafetybc.ca/sites/default/files/ sos_2016_casestudy_ammonia_final. pdf) one has to wonder if training will be sufficient such that no injuries or fatalities will occur with these “safer” refrigerants. Bill Lape is Director of EHS Programs and Compliance for Dean Foods. The opinions expressed within are solely his and do not necessarily reflect the opinions, policy or position of Dean Foods Company or its affiliates. Bill is a Certified Industrial Refrigeration Operator and a member of the National Board of Directors of the Refrigerating Engineers and Technicians Association.

Chlorofluorocarbon refrigerants are being phased out as part of the 1987 Montreal Protocol due to their tendency to deplete the ozone layer. Hydrofluorocarbons, or HFCs, are being phased out due to their “Global Warming Potential” or GWP, as part of the Kyoto Protocol. The above are broad, long term risks. How about their more immediate risks? While not caustic as ammonia is, CFCs and HFCs will, like ammonia, cause frostbite when bare skin is exposed. When exposed to high temperatures, CFCs and HFCs will decompose into toxic byproducts, including halogen acids such as hydrofluoric acid. as a safer alternative. What the articles fail to point out is that not only are these refrigerants being phased out, but that they too have their own inherent risks. On Tuesday, October 17, three people died due to an ammonia leak at an ice rink in Fernie, British Columbia, Canada. With the investigation still ongoing, already there are calls to replace all ice rink ammonia refrigeration systems in Canada with “safer” alternatives. Several articles found on the internet point to Freon refrigerants

While the exposure limits for these refrigerants are significantly higher than ammonia, they will displace oxygen with no warning outside of specialized sensors. There have been documented cases of deaths due to asphyxia from entering a space where a CFC or HFC refrigerant leak was occurring. (www. osha.gov/pls/imis/accidentsearch. accident_detail?id=200710556 and www.osha.gov/pls/imis/accidentsearch. accident_detail?id=200452654, for example) This is perhaps the most critical safety concern with these types of refrigerants. What about the newer refrigerants designed to take the place of CFCs and HFCs? While some of them do have odors to indicate a leak, the majority of them are moderately to highly flammable even at low airborne concentrations. This makes leak detection and mitigation all the more critical. Carbon dioxide, while not toxic or flammable, also displaces oxygen and is undetectable without sensors. Carbon dioxide systems also operate at much higher pressures than other refrigerant systems, which can lead to other hazards, such as catastrophic ruptures, if they are not maintained properly. All of the above leads me to this comment. Regardless of the refrigerant used, there will always be hazards associated with their use. The only true

conference CORNER GET READY TO BE AN EXPERT!

by Mary Hendrickx, Conference Manager This year RETA will be opening its doors and accepting Conference white paper abstracts from anyone interested in presenting at RETA 2018 taking place November 6-9 in Dallas, Texas. In the past, most presenters and white papers were invited. While we will still be inviting specialists in the field of refrigeration, compliance, and safety, we would like to give an opportunity for you to introduce your work to the RETA community. Before describing how this process will work, I would like to explain what a Conference paper is and the benefits of submitting one. Conference papers also known as “contributed papers” which differ from papers requested by invitation otherwise known as “invited papers”. Contributed paper abstracts are written with the goal of being accepted to a Conference after review by a Committee of peers. In RETA’s case, this would be for our annual National Conference. If accepted, the author would be expected to present their research by oral presentation to the Industrial Refrigeration community in Dallas come November.

There are many reasons why an abstract for a paper might be eliminated. Here is a short list of possible reasons: • The abstract duplicates other work/ does not report anything new • The abstract is poorly written • The abstract has been poorly prepared (inconsistencies, spelling or grammatical errors) • The abstract contains content that is perceived as promoting a business • Does not meet the guidelines or best practices for writing an abstract Should a contributed paper be declined, the author will be notified along with the reason for non-acceptance. Is all this really worth my time? Absolutely! Here are some noteworthy advantages that you may want to consider when deciding on whether to participate in submitting and ultimately speaking at a RETA National Conference. Attending and speaking at a Conference at a professional level is a great way to get in touch with your target audience and utilize the opportunity to communicate effectively with them. Speaking at a RETA National Conference

How does it work? The Technical Conference Committee will send out a “Call for Abstracts” which is a request for original research, innovative projects, collaborations, or other professional activities of interest to the Industrial Refrigeration community. The process of presenting a contributed paper begins with the submission of an abstract beginning in February. Abstracts should be 300-600 words in length and accurately convey the subject of the paper, its scope, and conclusions. The Technical Program Committee reviews the abstracts and decides which ones should be expanded into papers and presented at the Conference. The Committee also reviews the papers and determines which one it considers the best of the group. Accepted contributed abstracts will be published in a collection called “proceedings”, which is then sent or given out to all attendees. Abstracts will be scored on evidence of scholarship, methodology, originality, timeliness of the topic, and compatibility with a 45-minute presentation relevance to the areas of manufacturing, compliance, engineering, and operations.

on a particular subject automatically helps in building your credibility because it shows that you are well- versed on the topic of your presentation. Networking opportunities are many, especially when it comes to attending and speaking at a professional-level Conference. Not only will people get to know you, but they will also get to know what you do, and this is critical in the professional world. Once people

are fully aware of your expertise in a particular field, your career will soar to greater heights! In addition to sharing your expertise with others, you will build lasting connections, master your discipline, become popular with your peers, enhance your career, help others, and have a blast! Be sure to keep a look out for the RETA 2018 “CALL FOR ABSTRACTS” and consider submitting!

All of us with over 10,000 pounds of ammonia in our system are well aware of the EPA Risk Management Program Hazard Assessment requirements (40 CFR Part 68.20). Well, at least we have

Unmasking the mystery of the Worst Case Release & the Alternative Release Scenario by Lee Pyle, SCS Engineers

Do not fret; chances are that the inspector at your plant is probably not much more fluent in dispersion modeling than you are. In 1994, the EPA came out with their first draft of the RMP rule. It was not welcomed with open arms by industry. One of the biggest complaints was the potential expense associated with the Hazard Assessment portion of the draft regulation. With the comments received, EPA went back to the drawing board and came back with something much simpler as well as the RMP*Comp software. Good news — right. Well, yes, they simplified it such that it does not cost much to get a good Hazard Assessment report on paper. However, in the oversimplified of the process we have lost some of the finesse associated with the intricacies of dispersion modeling. Let’s start with the difference between

release scenario? Let us run a Worst Case Release using each set of meteorological conditions with RMP*Comp[ 2 ] ( see figure 1 ). Another difference between the two release scenarios is that they use different techniques: • Worst Case Release is a PUFF or INSTANTANEOUS Release • Alternative Release Scenario is a STEADY STATE Release A PUFF or INSTANTANEOUS release is when a large quantity is “dumped” in a short amount of time whereas a STEADY STATE release is a constant rate of release of an infinite amount of time. Using the example again, let us use the worst-case meteorology but change the “dump” time (note that this is not allowed under the EPA RMP rule — you must use a 10-minute time for your INSTANTANEOUS release) ( see figure 2 ).

of a possible situation at your plant, one difference is the meteorological conditions are different: • WCR: F Stability and 1.5 m/s wind speed • ARS: D stability and 3 m/s wind speed So what does that mean? Doesn’t more wind push the release further? No, more wind speed means greater dilution of your “cloud”. What are the effects of “Stability”[1]? Our atmosphere is three-dimensional, not two-dimensional. Wind speed causes mixing of our “cloud” in the X and Y plane (down and outward) while Stability causes mixing of our “cloud” in the Z plane (up and down). Stability Class takes into account, time of day, incoming solar radiation, and surface wind speed. Class A is the most unstable

Steady State Release: One area of the regulation that can cause issues in an inspection is the criteria under the Alternative Release Scenario is 68.39 (c): Documentation of estimated quantity released, release rate, and duration of release. I have highlighted “duration” because when using a steady-state model, duration has no meaning. It assumes that there is a constant release over time. For an ammonia system, it assumes no pressure-drop following the initial release or that the pressure is constant (aka the compressors keep operating during our scenario). Much debate occurs over how long it would take to stop a release. Some extremes include – what if it happens on a Friday night and the plant has no coverage over a weekend? Well, it could continue until the entire charge is released. Alternatively, we could have 24/7 coverage and a response team that can mobilize in 30 minutes. At the end of the day (or at the end of the EPA inspection), does it really matter when preparing the downwind distance for our ARS? No, because the RMP* Comp, Alternative Scenario is a “steady state” model ( see figure 3 ). While the logic is plain and clear, you still do not want to get into a debate with an EPA inspector. So best to go conservative on your response time and report a downwind distance of 0.1 miles than to have to justify being able to shut down a release in 30 minutes while still reporting a downwind distance of 0.1 miles. The last caveat for the ARS is to make sure the total quantity released does not exceed your WCR total quantity. Even though, we can release the same quantity using various parameters and get various answers, you just do not want to have to pull out this article to explain it all. Happy Modeling!

RETAHistory: 1919 Convention through the 1920 Operations

Then, as now, the RETA year begins with Conference. As in almost all of the years of RETA/ NAPRAE, 1920 was an interesting year. The organization was continuing to grow. 7 Chapters were in operation. Most were in the central region of the country. Chapters: Oklahoma Chapter #1, was meeting two nights per month on 1st street in Oklahoma City. Theodor Oderman served as Chapter President while A.R. Mitchell served as Vice President. O.K. Corken served as both Chapter Secretary and Treasurer. This was somewhat common in the early days of the organization. Della Hallmark had the role of Assistant Secretary and Assistant Treasurer. Della was from the large Hallmark Family of Oklahoma. M.A. Parsons was the Sergeant at Arms. The Kansas City Chapter, having been formed in 1919, was also active. Though meeting only one night per month, F.E. McDowell was serving a term as President. John Hanson served as Vice- President while B.J. Schmidt was serving as both Secretary and Treasurer. T.H. Hays was the Sergeant at Arms. Shreveport was the home of Louisiana Chapter #1. W.H. Phelps served as President while D.S. Brown assisted as Vice President. It is worth noting that this D.S. Brown is not David Brown. They are sometimes confused by historians. The by Vern Sanderson RAI, CIRO, Level A 2018 RETA National Treasurer Wagner-Meinert LLC

as Vice President, W.F. Roberson as Secretary Treasurer and J.E. Lawrence as Corresponding Secretary. Interestingly there was no Sergeant at Arms. Records from the Chicago Chapter are somewhat confusing. All officers were listed as “temporary”. Carl E. Loker as President, H.T. Whyte as Vice-President, Edward H. Fox served as Secretary Treasurer and Chas Nelson was the Sergeant at Arms. Committees & Boards: Then as now one of the strongest Boards (committees) was the “Educational and Examining Board”. J.E. Porter was Chairman of the Committee and while H.T. Whyte, and F.H. Ladd helped set the organizational standard for education and certification. The Publicity Committee was charged with getting the word out and expanding the organization. The Committee was an all-star cast. Members included WilliamMcCandlish, P.R. Cooper, and Martin Boyle who worked for Marris and Company. Charles Chapman of the Detroit Cold Storage Company also served on the Committee. The Detroit Cold Storage Company was an instrumental player in the storage of goods shipped through the great lakes. The Chairman of the Publicity Committee was non-other than Edward Fox, the Editor of Ice and Refrigeration Illustration, a publication of Nickerson and Collins. At this point it is probably worth noting the difference in governance between

famous David Brown worked from the Detroit, Michigan area. It is not known if they were related. The Secretary/ Treasurer was R.H. Bridges and C.E. Freeman was the Sergeant at Arms. The Atlanta Chapter was meeting monthly. A.I. Drake was serving as President, C.T. Baker served as Vice President, J.W. Yopp served as Secretary Treasurer, and B.F. Ritter was Sergeant at Arms. The Memphis Chapter met twice per month on Tuesday nights. William Fitzgerald was the serving President, Chas. Stanton was Vice President, David R. Williams was Secretary Treasurer and Peter Anderson was Sergeant at Arms. Texas Chapter #1, Dallas met twice per month and on Friday Nights. E.B. Wright served as Chapter President, H.C.

on Saturday Afternoon at 1:30 PM to allow the banquet to end before 4:00 PM. Outgoing Vice President J.E. Porter called the session to order in the absence of President E.P. Fryant. Secretary F.L. Brewer read the President’s address in his absence. In the closing of the address, President Fryant called upon those in attendance to “do our share and we will have the greatest Association in all the world”. The address included the following call for members: Give us men from the rank, Fresh and free and frank; Men of faith, and not of faction; Men of lofty aim in action; Men who never shame their mothers: True, however false are others. In the afternoon session, G.E. Kloss of the Franklin Ice Cream Company delivered a presentation titled “Refrigeration for Ice CreamManufacture”. It was very well received. So much so that Mr. Kloss was elected National President at the end of the convention. J.E. Porter delivered the presentation “Installation of Boilers”. This was followed by a Presentation by Norman Register titled “Engineer Work During Off Seasons”. This work was suggested by E.P. Fryant. Mr. Fryant “encouraged” officers of the organization to present papers at the convention. He went so far as to select topics he felt were appropriate to the organization. This paper will be republished in an upcoming issue of the RETA Breeze . The famous C.T. Baker presented a paper on “Electricity in Ice Plants”. This was followed by an extended discussion by those assembled of power consumption per ton of ice. Another discussion ensued concerning the Association’s role in the employment

changes of its members. As penned in the notes of the Conference: “It is not the policy of the association to encourage men in changing their employment, but where a man has definitely decided he is capable of earning more money, the association can do more for him than any private employment bureau, and of course no charge is made for the service. The secretary then mentioned a number of excellent positions available for members, and referred to others who had been placed in desirable locations during recent months.” On the second day of the Conference, Secretary Brewer read a paper prepared by President Fryant, “Lubricating an ice Factory”. This paper included revolutionary concepts such as developing oil specification and the keeping of an Oil Log. Bruce Dodson opened the afternoon session of day 2, with a presentation on the insurance costs of Plants. The presentation emphasized the concept of machine guarding. “We come now to perhaps the most important thing which an engineer can do to make the plant safe, and by which he can reduce the cost of insurance to the management of the plant. It is by providing adequate safeguards to dangerous machinery and to other hazardous conditions about the plant.” Many ideas were put forth in the discussions following the presentation. Even though this was the last presentation of day two, it was one of the most popular presentations of the Conference. Day three, the final day, opened with a presentation by J.D. Hansen entitled “Oil Burning”. The paper touted the

NAPRE of 1920 and RETA of today. RETA is governed by a Board of 12 Directors and 5 National Officers. NAPRAE of 1920 utilized a Board of 9 Advisors, a 3 person group of Directors and 6 National Officers. The Board of Advisors consisted of O.E. Morris, W.H. Biesley, F.H. Ladd, Carl Nessler, A.E. Page, Norman Register, I.W. Marshall, and Bennett Story. E.P. Fryant of the Bogaluse Paper Company served as Chairman of the Board of Advisors. The three directors of the organization included: Henry West, Norman Register, and J.E. Segar. The National Officers for 1920 were an interesting lot. Eugene Grey served as the Sergeant at Arms. Eugene was an employee of the City Ice Company of Rushton, Louisiana. W.R. Ilch served as the National Treasurer and F.L. Brewer served as Secretary. James Glenn served as Second Vice President. Carl E. Loker with the Chicago Artificial Ice Company served as First Vice-President. G.E. Kloss of the Franklin Ice Cream Company served as National President. Conference (1919): Referred to at the time as the Tenth Annual Convention, the 1919 Conference was held at the Coates House in Kansas City, Missouri on December 4th, 5th, and 6th. Attendance was less than anticipated due to labor shortages in some areas and the extreme shortage of gasoline. The Conference was plagued by issues. It was the only convention allowed to be held in Kansas City during the fuel crisis. The convention ceased at 4:00 PM to allow everyone to get back to their rooms prior to nightfall. Even the traditional banquet was not immune from the curfew. The banquet was held

Therefore, the Board of Directors is hereby instructed to take steps to affiliate with the proposed centralized body; and authority is hereby given the Board of Directors to extend such financial support as the resources of the association will permit. III. RESOLVED, That this Association in convention assembled hereby extends its thanks and appreciation to the retiring officers and committees for their unceasing efforts and co- operation to further the best interests of the Association during their tenure of office; and for their work in making this convention a success. IV. RESOLVED, That this Association extends its thanks and appreciation to the management of the Coates House for its generosity in furnishing accommodations for the holding of its convention; and for the many favors and attentions extended its officers and members during the meeting. The Condolence Committee announced the deaths of Theodore Vilter and Alexander H. Schweiss. Many were saddened by the news that the industry had lost two giants. Elections were held and the Conference was adjourned.

After Conference, the members retired to their Chapters, but the National Officers continued to publish information for the members. On January 3rd, the Kansas City Chapter elected officers. They were sworn into office on Friday, January 23rd. They were: J. D. Hansen as President, C. C. Norman as Vice-President, G. K. Williams as Secretary-Treasurer, and S. F. Hannum, as Sergeant at Arms. Additional Directors included: James Gallup, G. E. Sterling, and P. E. Roessner. In February of 1920, the revised transcript of W.A. Converse’s “Boiler Feed Water” presentation, presented at the 1919 convention was finally released. S.C. Horst released an article entitled “Cost of Packing Friction”. Units of heat measurement. Thermometers: Their uses and application to refrigeration and ice making plants. Production of cold (thermodynamics). Manufacture and tests of refrigerants. Insulations: Uses and qualities as applied to cold storages and ice plants. Heat transmission through various substances. Systems of refrigeration.

benefits of burning oil. I. G. Trimble then presented a paper entitled “Economical Boiler Settings”. The assembled body was then told that they would have the privilege of being addressed by Mr. J. F. Nickerson. The topic of his speech was a report on the unification of the various refrigeration interests and the need for a unified voice. A new constitution and bylaws were voted on and passed by the assembly. A total of five resolutions were passed. I.

Compression system: The use and care of the compression machine. Absorption machine: Construction and economical erection. Absorption machine: Operation and care. Calculation of capacities of compression and absorption machine unit of plant economy. The first lecture was given by Mr. Koehler after the Chicago Chapter meeting. The March Kansas City Chapter meeting explored the subject of “Can Galvanized Pipe be Successfully Used in the Construction of Ammonia Condensers or Expansion Coils” The Chicago Chapter met on March 3rd. The highlight of the meeting was an address by Education Committee Chairman C.W. Kohler. Chairman Kohler’s committee consisted of W. F. Lambin, H. T. Whyte, P. L. Tolerton, John A. Jung, and Carl E. Loker. 12 lecturers were outlined. April saw the publication of “Reminiscence” by Secretary F. L. Brewer and the Texas Chapter relocating to Woodman hall in Dallas for their April meeting, to allow for more room for members. The Chicago Chapter’s May meeting saw the second educational program,

“Thermodynamics” presented by A. J. Polcinsky, May 13th was the date that the Texas Chapter member’s wives and children were invited to attend and were treated to sandwiches and ice cream after the meeting. And in his May report, R. H. Bridges reported that the Louisiana Chapter was continuing to expand. At the June meeting of the Chicago Chapter, Fred C. Berk presented a lecturer on “Origin, Manufacture and Application of Ammonia”. A. H. Goelz presented the second lecturer of the evening on “CO2 as a Refrigerant”. The membership also voted to cancel the July and August meetings. In July, President Kloss issued a National call for members to attend and take part in meetings. ”Likes the N. A. P. R. E.” was published By F. P. Siebel. August saw the publication of F. C. Pituuzv’s article “Artificial Refrigeration and The Status of Matter.” September saw a flurry of articles as excitement began to build for the coming convention. They included: “Suggestions to the Plant Owner” by E. P. Fayant, “Shell Brine Cooler Trouble” and “The Machinery Situation” by I. E. Porter, “Getting Ready for the Next Season” by J. E. Lawrence, and “Stack Repaired By Acetylene Welding” by C. W. Kohler.

National President Kloss, traveled to Chicago to meet with Fred Berk and the rest of the organization committee to discuss preparations for the upcoming convention. The Chicago Chapter met on September 8th. The Business meeting was centered around preparations for the upcoming convention. The Auditorium Hotel was chosen to be the Headquarters for the convention. Chicago Chapter President MacDonald appointed A.J. Plocinsky as Chairman of the Finance Committee. In order to accommodate those members which worked nights, a motion was made and carried to move the time of the meeting up. This motion included provisions to change the meeting schedule to have two meeting per month. One educational and the other the regular business meeting. W.H. Mikkleson was scheduled to present a paper entitled “Insulation, Its Uses and Qualities as Applied to Cold Storage and Ice Plants; Heat Transmission through Various Substances” however, Mr. Mikkleson was called out of town, so Vice Chairman H.T. Whyte read the paper. The Chicago meeting was held on October 13. Thomas C. McKee presented the educational program “Refrigerating

Systems”. Mr. McKee was from the Carbondale Machine Company, a compressor manufacturer of great renown at the time. In November, National Secretary Brewer drafted an article on the reasons to attend the upcoming convention. National Second Vice President Glenn saw his article “Refrigerating Plant operation” published for the first time. J.H. Lamar drafted an article entitled “Plant Overhauling”. November 11th was the next Chicago Chapter meeting. As you can imagine the last-minute preparations for the National Convention monopolized the business meeting. Harry Sloan, a well-known engineer from the Vilter Corporation, conducted a short course on ammonia compressors and their efficiencies. On November 12th, the Kansas City Chapter issued an announcement of their new officers: James Gallup as President, T.G. Shawhan as Vice President, H.L. Frentop as Secretary/ Treasurer, and F.J. Taylor as Sergeant at Arms.

And with that, it was time again for Conference and the New Year began. We hope you’ve enjoyed this look into the History of RETA. As you can see, many people have contributed to the success of the organization at the National level and the Chapter level. If you have any corrections, please send them to us. If any of the articles mentioned seem of particular interest, please let us know and we will attempt to return them to print.

credentialing exams since 2002. RETA Testing Corner provides information and answers questions from RETA members, candidates and others to help them earn and benefit from RETA credentials. RETA delivers a comprehensive score report after every CARO and CIRO test, but some candidates are uncertain how to use the information in these reports. Two examples are provided to show how to interpret these results. The first report ( see figure 1 ) is for a candidate whose scores in 5 of 10 CARO content areas were below 70% correct. These five areas are highlighted. A total score of 70 or higher is required to pass. This candidate’s total score of 69 means that 31 of the 100 scored questions were answered incorrectly. This candidate did very well in the five content areas with scores above 70% correct — and poorly in five content areas with scores between 28% and 62% correct. The candidate also used just over half of the 180 minutes allowed for the test. That suggests that one problem may have been taking too little time to read each answer to every question before selecting the BEST answer. Each question includes three wrong answers

Lubrication.................................................................................................. 80% correct

Evaporators & Cooling Units..................................................................... 77% correct

Condensers & Receivers............................................................................ 90% correct

Purging....................................................................................................... 50% correct

Safety Standards & Procedures................................................................. 62% correct

Total Scored Questions.............................................................................. 69% correct

Unscored Pilot Questions.............................................................................No score

Total Time Used out of 180 Minutes. .........................................................97 minutes

that reflect common misunderstandings and errors that candidates may find plausible if all the information in the question is not considered carefully. The CIRO scores ( see figure 2 ) represent two attempts by a candidate who scored higher in four content areas but still needs to improve in four of the nine CIRO content areas. This candidate scored below 70% correct on 8 of 9 content areas on the first CIRO attempt. The total score of 61% correct on the first attempt means that 49 of 125 scored questions were answered incorrectly. The candidate then scored above 70 in 5 of 9 content

areas on the second attempt. The total score of 67% means that the candidate answered 41 of 125 scored questions incorrectly on the second attempt. CARO and CIRO Practice Tests take this information one step further by directing candidates to the chapter in the appropriate RETA book that supports the correct answer to questions they missed. These tools are designed to help CARO and CIRO candidates understand how to prepare for a future attempt. We welcome your questions about RETA’s credentialing exams and activities.

by Dan Reisinger, RETA Certification Manager Last year was a good year for the RETA certification program. As of December 31, 2017, there are 1,367 CARO Credentials, 1,405 CIRO Credentials, 30 CRES Credentials, and 15 RETA Authorized Instructors (RAI). The Certification Committee has started work on the new Service Tech Level exam that will be rolled out in the first half of 2018. On January 8, 2018, RETA submitted our 5-year reaccreditation application to ANSI for the CARO and CIRO Certifications. Two ANSI auditors will now review the 1,566 pages of information that was submitted and then will visit RETA HQ in late February or early March for their site visit. When the auditors have completed their tasks, the application will then be sent to ANSI’s Personnel Certification Accreditation Committee (PCAC) for their approval. If you would like to become more involved in RETA, the Certification Committee would welcome your help. If you are interested please contact me at dan@reta.com or 541-497-2955. Certification Update
