FROM THE DESK OF THE PRESIDENT

Thank you for the opportunity to address the membership. This is my final Presidents report. It has been an honor to serve as President and I look forward to many years as a RETA member. This year has not been without challenges. But the challenges were confronted and resolved. Many things beyond our control affected our year. RETA is blessed with a fantastic Headquarters staff. In addition our elected leadership, Vice Presidents, Treasurer, Board of Directors, Chapter Presidents and Chapter Officers are top notch. All worked very hard to continue to serve the membership through the pandemic. The committee chairpersons and sub-chairpersons work very hard for the organization. Thank you to all of them as well. I would also like to thank Sara Louber and James Barron at RETA HQ. Without their assistance this year may have turned out very differently. The organization is strong. Surprisingly strong! It is a testament to the leadership of HQ and the Board of Directors. In my acceptance speech last year, I said that I believed the refrigeration industry needs one voice, the operator’s voice, RETA’s voice. But there are many facets of our industry and as some of those facets struggle, the industry struggles. RETA stands ready to do our part for the membership and the industry. RETA will lead the industry forward. Our incoming President will be the voice of the industry. It is the job of every member to counsel

Vern Sanderson, RETA National President

The fall board meeting is upon us and the committees have a lot of things in process. You should receive some of the news in the next issue of the Breeze. Conference is upon us. Our first virtual conference. We are very excited. Both to experience this new platform and to return to the old. Please avail yourself of the benefits this platform has to offer. Our new officers will be sworn in soon. There is a great slate of officers and board members, they will serve the organization well. I look forward to the coming year. I assure you it will be better than this one. Thank you again for the opportunity to serve as your President. It has been a life altering experience that I will never forget.

him as you’ve counseled me. The organization is in great hands.

FROM THE EXECUTIVE DIRECTOR

Hello All, It is a cool morning, and a hint of fall is in the air here at RETA HQ. The leaves are changing color, and some are already dropping. Yes, Fall is here. Not only are the leaves changing, but so is our ever changing understanding of “normal”. Seven months ago I never would’ve dreamed you couldn’t shake the hand of your RETA brother in arms or hug a lifelong RETA friend. RETA HQ is getting ready for our first and hopefully last virtual Conference. This year has been a real struggle for everyone and continues to be so. We sure hope and pray that this virus is on its way out so we can resume some sort of normalcy. This year’s Virtual Conference will give our RETA members a chance for education, PDH’s and some networking time with others in our Industry. I know its not the same as being in person and its hard to see the value so let me try and put this into perspective. 1. Those of you that are certified need continuing education hours for your certification renewal. You can get most of the PDH’s you need at this Virtual Conference while learning valuable educational material. 2. There are vendors and suppliers that have Virtual Booths that may help your company with your refrigeration parts, service, and supply needs. You can source and find what parts and services are available in today’s market.

4. This is an opportunity to stay current on what is happening in our industry. 5. RETA will have a live virtual business meeting where you will be informed as to what the National Committees have been working on this year and how the Association is faring this storm. All virtual Conference participants will have the opportunity to vote on the slate for incoming RETA Officers and Board Members. 6. The RETA-Training Institute has worked hand-in-hand with the Conference Committee in putting together the first ever WiNR (Women in National Refrigeration) Comedy Hour at no additional charge. Everyone is invited and welcome to attend this event. 7. You can’t miss the live award ceremony and the swearing in of the incoming RETA officers and Board. Join us in finding out which deserving members will be honored this year. You’ll also want to help us say goodbye to the outgoing National Chairman Arlie Farley and Board Members Bengie Branham, Frank Kologinczak III, Matt Hayes, and Mike Hawkins. It has been an honor and pleasure to work with such a great group of knowledge advisers, friends, and RETA advocates who love and

RETA Executive Director Jim Barron

I want to say a special thank you to Vern whose positive, proactive and steadfast leadership and support this year as the National President has allowed RETA to remain viable and on course during this trying and unusual time. Well there you go, some food for thought about the virtual Conference. RETA truly has the best members in the Refrigeration Industry. We all strive to be the best and to do the right things for the right reasons. We keep the world’s food safe for our consumption and the beer cold for when we can all be together again.

Please stay safe! God Bless every one of you, Jim Barron

support the industry. We will also be welcoming Vern Sanderson as the incoming National Chairman and Eric Teale as the incoming National President.

3. There are fantastic prize

opportunities throughout the Conference.

EPIC FAIL

FIGURE 1

UNKNOWN CONTROLS Awhile back, I was helping a facility prepare for an upcoming OSHA audit. During a tour of their facility, I stopped outside the maintenance shop and observed some control switches as shown in Figure 1. The one on the left indicated that it was the Emergency Ammonia Shut Down. The one on the right was unmarked. I enquired as to the function of both switches. The facility manager THOUGHT that the left button shut down the refrigeration system, but had no idea what the one on the right did. So, we arranged to test them. Upon testing them, we discovered that the break glass switch to the right of the door actually shut down the ammonia system, while the push button switch on the left side of the door merely closed the automatic King Solenoid Valve. After determining this, we made a quick labeling change as shown in Figure 2. “Now,” I said, “What about the break glass switch panel outside of the Boiler Room adjacent to the opposite side of the Machinery Room?” Their response? “What Break Glass Panel?” The panel in question is shown in Figure 3. When we opened up the panel, no wires had ever been pulled to it, much less connected. So, the moral of this story is that IIAR6, the Standard for Inspection, Testing, and Maintenance of Closed-Circuit Ammonia

1. No documentation of the function of the safety switches Lack of training on the proper operation of the safety switches Lack of proper labeling of the safety switches Lack of inspection and testing of the safety switches This particular set of Epic Fails is low hanging fruit for an auditor or a regulator. However, avoidance of fines should not be our primary reason for avoiding these Epic Fails. We should be avoiding these Epic Fails in order to keep our employees and the public safe. I encourage everyone who is responsible for operating or maintaining an ammonia refrigeration system to look at the above list of Epic Fails and honestly evaluate how well your facility has done addressing them. If you have photos of an Epic Fail please pass them on to nh3isB2L@gmail.com. Bill Lape is Project Director for SCS Engineers. Bill is a Certified Industrial Refrigeration Operator, a Certified Refrigeration Service Technician, and a member of the National Board of Directors of the Refrigerating Engineers and Technicians Association. 2. 3. 4.

Refrigeration Systems from the International Institute of Ammonia Refrigeration (IIAR) states in Chapter 12 that The following must be checked on a semi-annual basis: 1. Visually inspect the emergency shutdown switch for damage

2.

Visually inspect for proper installation of signage

On an annual basis, the following is to be checked: 1.

Functionally test the emergency shutdown switch

Based on the results of our little inspection and testing, it is safe to say that none of these were being done. Now you might ask, “When was this discovered?” It was discovered in 2014, well before IIAR6 was published. However, Bulletin 110, Start-up, Inspection and Maintenance of Ammonia Mechanical Refrigerating Systems, also from IIAR, states in Appendix D.5 that “regular tests of the effectiveness of detection and isolation systems should be made at intervals not exceeding three months.” If one were to argue that that was referring to electrical isolation systems that were called out in Bulleting 110, one only has to look to Section 6.6.4 of Bulletin 110 to see that it called out that “at least annually, safety cutouts shall be tested.” So we can see a number of epic fails with this one:

CHEMICAL FACILITY ANTI-TERRORISM STANDARD (CFATS)

A great topic. This regulation has been under emphasized since its initial rollout. The paper outlines a step by step process to comply with this regulation. This includes a great guide to getting started. Concepts are confirmed through references. If your facility has already attempted to comply, this presentation is a great way to review your current program. If you haven’t started or if you believe this program doesn’t apply to you, I suggest you consider the general duty clause. This program provides a great mechanism to look at your facility security.

T he Chemical Facility Anti- Terrorism standard (CFATS) Congress in 2007 to be security regulations that govern certain chemicals of interest (COI) at particular concentrations. The final rule was first published in the Federal Register by the Department of Homeland Security on April 9, 2007. The regulation became effective on June 8, 2007. An Appendix A to the regulation was published in the Federal Register on November 20, 2007. It was intended to address concerns raised by the industry and academia over what that is codified in 6 CFR Part 27 was initially authorized by

The CFATS regulation created risk-based performance standards for managing the security of facilities that have on-site quantities of COIs over threshold amounts established within the regulations. The intent is to prevent these COIs frombeing used in a terrorist attack. This previewwas compiled by Sarah Selzer in conjunction with the author, Bill Lape.

What reviewers have to say:

When I was asked to review the paper, my first thought was incident investigations again? What else can be said that hasn’t been said? I was wrong. Michael has compiled a lot of good information. The first section of the paper, “Introduction to the Incident Investigation Element”, lays the foundation for why the requirement exists. Section 2,“OSHA Requirements for the Incident Investigation Element” looks at the OSHA as well as EPA requirements. Many times, we think we know what the standards require, but many times, our opinions are based upon what we were told not what we read. Sometimes, we know what the standard says up until the time we stopped reading. This section provides a good opportunity for us to recalibrate what we know about Compliance”looks at what should we do beyond what the standard requires. I filed this section under “value added investigations”. Section 4 is a walkthrough of how to perform the investigation. The whitepaper is extremely detailed, I can’t imagine how Michael can cover all of this during his presentation. But from reading the whitepaper, I believe that the presentation will be an hour well spent. the standards. But the best sections were yet to come. Section 3,“Going Beyond

Following the requirements of OSHA’s Process Safety Management 29 CFR 1910.119(m) and EPA’s Risk Management Plan 40 CFR Part 68.81 for Incident Investigations, this paper will provide comprehensive and specific instructions on how to meet the requirements of these standards for compliance. This paper will demonstrate why it is important to go

beyond compliance and utilize the incident investigation procedure as a tool for continuous improvement.

Keith has a long history in the industry. It’s invariably interesting

to hear his opinions and observations. It is always educational.

In this paper, Keith has tackled a tough subject. One that too many consultants simply say“write a check, replace it or repair it”. Keith outlines a much more fiscally responsible course of action. In addition to instructions, the white paper also contains a case study which walks you through the process. As noted, documentation is key. You must document your rationale. The presentation should be excellent. Thanks Keith!

What reviewers have to say: While not the main focus of the paper, Mark includes a great recap of the evolutionary changes in Ammonia Refrigeration. This is a great primer for less seasoned refrigeration engineers to see how our thoughts have changed. Mark identifies lowering of the refrigerant charge as an evolutionary change. The paper discussed why this change occurred. Including some great detail on the impact of this evolutionary step. There is also a discussion of our “more mature view of Safety”. Practices which were considered standard for many, many, years are now considered dangerous. A recent discussion of RETA Industrial Refrigeration 1, centered around manual purging. Manual purging was once considered a common practice. Now it is considered a necessary evil, to be avoided if possible. Mark cites several very good examples. Marks’discussion of evolutionary change #3,“the expanding world of Natural Refrigerants”starts off with one of my favoriteWinston Churchill quotes“You can always count on Americans to do the right thing – after they’ve tried everything else”. Mark discusses failures of other refrigerants. This includes some very good examples. Though he did not include Methyl Chloride, probably because it was discontinued long before he was born. LOL But the main topic of the course is vessel design. This is a good whitepaper and I believe it will be an even better presentation.

Continuing Education Credit: 1 PDH REFRIGERATION PRESSURE VESSELS: DESIGN CONSIDERATIONS FOR AN EVOLVING INDUSTRY

Author: Mark Stencel

T oday, at an accelerated rate, we are witnessing multiple evolutionary changes in the refrigeration industry. One could write volumes about these if one were to consider all the impacts these changes have on all the components of a refrigeration system. The intent of this paper is to invite the reader to consider the impact that some of these changes have on a simple and static part of the refrigeration system, the refrigeration vessel. By this consideration, designers and operators of refrigeration systems are challenged anew to reflect on the interconnectivity of all we do. Further,

they are urged to be alert to the broad impact (i.e. design parameters, safety, and efficiency) of any change and as they occur, to apply a careful review to all the interconnecting affected segments of a refrigeration system. By doing so, they will improve the safety and efficiency of systems throughout the next waves of natural refrigeration system development.

Creating an effective Visitor Plan or Guidelines is always a struggle due to the ever-changing operational needs a facility may have. Each day can hold new hazards or obstacles which onsite personnel may have to navigate in order to evacuate quickly and safely. Escape routes can change due to construction, new equipment, and a variety of daily activities. Requiring all visitors unfamiliar and untrained to your facility to be escorted by an employee or contractor that is familiar with your facility and trained on your Emergency Action Plan will drastically make your plan more effective. In the white paper, Gary has provided some great scenario’s and advice to help make your Emergency Action Plan more effective. I highly recommend attending Gary’s presentation.

W hen escaping ammonia, the indoor or outdoor variables such as ventilation, room size, weather, temperature, wind, humidity, and the type of ammonia release can make escape and rescue difficult.

What reviewers have to say:

Very enlightening. The study is enjoyable. FSMA compliance is certainly something the industry needs to be very aware of. I think that there are probably too many engineers who are unaware of the potential issues. Hopefully, this presentation will raise awareness.

“…. got my attention and I certainly wanted to read more.”

Continuing Education Credit: 1 PDH FSMA COMPLIANCE AND ENERGY SAVINGS WITH AN EFFECTIVE BUILDING ENVELOPE Author: Randal Bogrand

I thought the author was very broad in his assumptions about existing installations.“The Traditional lo-temp building envelope installation does not hold temperature, will not keep ice and condensation from entering the building, is not FSMA compliant and contaminates food stored in the lo-temp facility. See Appendix 2 for examples”. I believe this is the case in some facilities, possibly most facilities. But to say that traditional installations do not hold temperature or prevent ice and condensation from forming may be an overstatement. I think our organization, as well as our competitors have been very proactive in trying to prevent migration and I certainly think our systems hold temperature. However, the authors statement got my attention and I certainly wanted to read more. The case studies were fascinating and easy to follow. I learned a lot!

T his paper’s purpose is to elucidate the Food Safety Modernization Act (FSMA) compliance and energy effects of a properly installed building envelope on freezers and coolers. It will be based upon industry research and the results from a 2-year long case study on 2 separate full building envelope installations in the Midwest and Southern U.S. The results show 100% compliance with the ice and condensation restrictions of FSMA and an energy savings of 48% and 51%, respectively. The primary objectives and scope of the study were to objectively determine what the effect of installing a state-of-

the-art building envelope (correct insulation, vapor barrier and roofing membrane) on an existing freezer/ cooler, if any. The rationale for the study was to obtain this missing information for Building Managers, General Contractors, Operational Teams and building owners to help determine a rational scope of action to FSMA, FDA, USDA and OSHA compliance and energy savings on their current, or to be constructed, freezers and coolers.

RETA in the year 2020, marks a first with virtual chapter meetings, and in the form of a first ever “Virtual National Conference”.

2020 has seen the rapid growth of Home Schooling, Online Training, and Distance Learning. RETA made available to its membership the RETA Online Training at no cost, so that members could continue to have a way to earn their Professional Development Hours (PDH) necessary to keep their Certification current. 2020 is the year that RETA completed the review and revision process of Industrial Refrigeration 1 & 2. Both are available in the RETA bookstore and in the RETA online training program.

and have a GWP less than 150 are the “natural”refrigerants: carbon dioxide, ammonia, a few hydrocarbons, and the newest class of synthetics called hydrofluoroolefins (HFOs).

2020 also marks a somewhat schizophrenic mandate by the U.S. EPA. Under their (now vacated, but under appeal) SNAP program (Significant New Alternative Policy) Final Rule 20, R-22 and other“green house gases”were to be phased out or reduced. Section 612 of the Clean Air Act provides that the EPA must prohibit of a substance where other substances are available that pose“less risk” to human health or the environment. So, what does that mean? Good question. The EPA’s list is somewhat fluid, the program is periodically re-evaluated by the EPA and decisions change based on several factors. The attempt to reduce the use of“ozone damaging synthetic refrigerants”has resulted in some refrigerants previously thought to be acceptable to also be placed on the list of banned substances. R-12 was the first to be banned in 2000. As of 2020, Other refrigerants originally thought to be ozone friendly are also now targeted to be or already have been eliminated, including: HFC-134a, R-141b, R-176, R-404A, R-405A, R-406A, R-407B, R-410A, R-410B, R-414A, R-414B, R-421B, R-422A, R-422C, R-422D, R-428A, R-434-A, R-507A, just to name a few. R-22, for decades a favorite refrigerant, widely used in industrial refrigeration as well as commercial and residential refrigeration and air conditioning equipment, was originally scheduled to be eliminated by the Montreal Protocol. R-22 can no longer be manufactured in the USA and may not be imported. Meaning the price and availability will soon make it prohibitive to use, especially in large scale refrigeration systems. Other refrigerants, originally thought to be acceptable substitutes, were or are in the process of being reduced or eliminated. In addition, some states including California, have adopted their own restrictions on synthetic refrigerants. Beginning Jan. 1, 2021, refrigerants with a GWP of 150 or greater are prohibited in new stationary refrigeration equipment with a charge size of 50 pounds or greater. For refrigeration, the only common refrigerants that are non-ozone depleting

What is the BOTTOM LINE ? • Ammonia and Carbon Dioxide are natural refrigerants. Both are thermally very efficient as refrigerants. Both have NO ozone depletion potential, meaning they will be around for a long time. Both represent the future of refrigeration. • To survive and thrive in our new reality we all need to work harder to improve our job skills.

Challenges ahead include:

• Economic disruption. • Continued civil unrest. • Breakdowns in our basic supply chain, with everything from food to toilet paper becoming more expensive and less available. • More people competing for fewer jobs.

• 5.7 resistance film type touch screen • Multiple languages • USB connection for import and export of settings, data logging and screen captures • Communication ports provide read and write data using Modbus RTU and Modbus TCP/IP • Automatic capacity control

This roller-coaster is just getting to the top. Strap in, hold on, and remember what Benjamin Franklin was quoted as saying, “Those who would give up essential Liberty, to purchase a little temporary safety, deserve neither liberty nor safety.” Hope to speak to you at the conference, Be well Vince Grindel, RETA Education Coordinator

In Memoradum of Richard “Pop” Baseler A couple of weeks ago longtime RETA member Glen Schrot shared a memory of one of his acquaintances and fellow RETA member who passed away last month. Richard D. “Pops” Baseler, August 19, 1928 - September 19, 2020. In addition to Glen, Mr. Baseler’s son Dan shared in the following. Rich’s life story is such a journey, his dad was thrown into the refrigeration business under strange circumstances originally working for Vilter and later a distributor in the 1930’s. Rich spent his young days going to work with his dad working on a variety of very primitive refrigeration systems like the 24 square block ammonia loop in the downtown St Louis, Missouri area. The compressors using large horizontal 30” bore piston compressors and the river for condensing. After high school, Rich signed up for the Navy in WWII to be stationed in the South Pacific with the “Sea Bees”. His specialty was Local 562 Pipefitter working for National Refrigeration, the Vilter

Representative. He traveled extensively in the 50’s and 60’s presenting at local professional organizations and was widely known for many years. He ran Paragon until 1998 when he turned it over to his son Dan Baseler with grandson Zach Epple (4th generation refrigeration legacy.) At age 70 he retired to working only a day or two a week, then later only as needed for engineering and technical support. Rich was a longtime member of RETA, life member of ASHRAE, RSES, and early member of IIAR. His contributions to the Industrial refrigeration business are endless and he has passed so much on to all he knew. Join me in the memory of our friend, fellow and mentor, Rich Baseler.

refrigeration, but they really did not have any opportunities to utilize this talent, so heavy equipment operator was what he was assigned to. Once out of the Navy he took the GI Bill and attended College at Missouri School of Mines at Rolla, today known as Missouri S&T, and attended Purdue University for his graduate work. He An opportunity arose at ALCO Valve Company where he spent 24 years. He then worked at the Frick factory in St Louis, the LV Filter Company until 1976 when he was asked by the owner of Krack to join Hussmann to help the transition of the sale between Krack and Hussmann. After about 8 years he saw an opportunity to start Paragon Engineered Products in 1984 and become the regional Krack worked for Herman truck body company right out of college, designing refrigerated trucks.

overtime for your people? Sometimes the labor costs alone justify changing priorities or shifting your crewing requirements to add additional people. Some Food for Thought We need to recognize several rules of business that can make our jobs a little easier. First, employers are in business to make money, not to give us a place to go five to six days a week. We should understand there is nothing wrong with making money. The more money our companies make, the better our jobs will be. However, not to spend money when required to do so to make money is wrong. Unfortunately, some man­ agers fall into this trap. I truly believe there is no concrete answer to this type of response. The type of change needed must come from within the individual. The second rule of business is maintenance/engineering departments are recognized in general accounting practices as an expense, not an income item. We sometimes need to remind upper management maintenance does not cost, it pays. The third rule of business is for any business to flourish in good as well as troubled times, they must limit their expenses and maximize income. The fourth rule is to spend money wisely. One more point should be noted. We need to take a step back and evaluate our approach to our general managers. Do we give them all the information they need to make a wise decision? How well do we build a case? Do we share our triumphs and not just our defeats? Do we expect to get everything we ask for and fight too hard if we don’t get it? Include your manager in the decision process by starting off with the statement, “I need your help.” Most importantly, have you hugged your manager today?

by JimMarrella J.C.MARRELLA & ASSOCIATES “ Q . We just corrected a condition in our engine room which, if we had discovered earlier, would have saved us a lot of work. How can I get my general manager to recognize the importance of engine room managing?

A. Any good manager will spend money to save money. A manager must believe, however, that money he puts out is well spent. Maybe your manager does not really understand all that is happening in your department. Maybe he does not understand the tangible and intangible events occuring with proper engine roommaintenance. This may be a good time to let your manager know all the costs of the repairs made to this piece of equipment. Then tell himwhat it would have cost if the problemwas discovered earlier, not that it would have saved your department a lot of work... Remember, it is not what you say, but how you say it. Build Your Case When this piece of equipment went down, did you have to start additional equipment that was more expensive to run? Include all cost involved in the “event.” Everything we do in the maintenance department is and can be translated into dollars. Was there any

What to Expect when you’re Expecting... A Regulatory Inspection By: Marie Samson, SCS Engineers

R egulatory inspectors are going to inspect you sooner or later, which means now is the best time to organize your safety and compliance documentation and ensure everything is prepared for the inevitable visit by a regulatory inspector. Nowmore than ever, a regulatory inspector will send out an inspection notice to notify the facility of the impending inspection. It may be sent via email or perhaps by the postal service, otherwise known as“snail mail.” In that notice, especially if the

With the current pandemic, a regulatory inspection is probably the last thing on anyone’s minds right now, especially when many regulatory inspectors are not able to come on-site to conduct the inspection. In California, some of the local administrating agencies (CUPAs) are beginning to send out notices that they will be performing a desk audit on the facility’s PSM/RMP/CalARP program with the intention of a follow up on-site meeting once the stay-at-home orders have been lifted. So what does that mean for facilities with ammonia refrigeration systems?
