FROM THE DESK OF THE PRESIDENT

Greetings everyone, I hope that your New Year is off to a wonderful start and that you will be able to successfully stick to and achieve your New Year’s resolutions. Recently our church hosted a movie night showing “The Jesus Revolution” which was based on a true story of the late 1960’ s into the early 70’s about the hippies coming to Jesus and creating a revival in Christianity. Now before you start to think that I’m going to start preaching to you, rest assured that I am not nor is that my intent. However, as I watched the movie and they mentioned that this was one of the largest religious movements in our country’s history and that it was the rebirth or revival of one church in particular, thoughts of RETA popped into my mind. The hippies in the movie that started to attend the services and believing, feeling saved, started telling their friends about Jesus and started bringing friends with them to services and prayer meetings. The next thing you know, they’ve outgrown the church and expanded to a giant circus type tent; of course, this was Southern California with that beautiful weather! What started out as a small church of 10-20 is now into the hundreds, possibly thousands. I know, I know… where is he going with this. Well, here it is. I know everyone reading this article loves RETA and has the RETA passion. But those of us active in our chapters know that there are a lot of contractors or operators in our area that aren’t at these meetings. The same is true for our National Conference. So here is where I

Mike Hawkins CARO, RETA National President

am going to put this all together. I challenge all of you to be a “Refrigera tion Hippy” and start telling those that you encounter in your daily work travels that are not aware of or may not know much about RETA. Bring a friend to your next chapter meeting, share what RETA has done for you. In my article last month, I mentioned how I was wel comed in many years ago as an “industry rookie.” When I attended my first chapter meeting at the Southeastern PA chapter, I was welcomed with open arms. Everyone was willing to share their vast knowledge and stories of being in the industry, some for many decades. Then I attended my first conference, feeling like the proverbial fish out of water. Guess what, the same thing happened! I was welcomed, folks shared, told stories, taught, and that was just on show floor before I got to my first tech session. We are facing a time where there are so many knowledgeable folks retiring from our industry and there are many new young people joining our ranks. It is our job, scratch that, it is our duty as stewards of RETA and the refrigeration industry to welcome these new folks with open arms and mentor, teach, and share with them the same way it was done with so many of us when we got

CIRO, CRST, RAI Schwan’s Company Executive Director: Jim Barron 4 RETA.com

involved in this fantastic industry. I’ve said it before, and I’ll say it again to whomever will listen to me…. I would NOT be as successful as I am without all the knowledge that has been shared with me by so many people at different chapter meetings and National Conferences! So again, I challenge all of you to spread the word about RETA and invite folks to your local chapter meetings. On top of that, Dan Denton does a terrific job of sharing the chapters meeting schedules and their online meeting information, they’ll be sure to find something of interest. Let’s fill up the meeting rooms at the chapter meetings, standing room only…. Let’s start a “RETA Revolution!”

Thank you, Mike Hawkins, CARO RETA National President

manufacturers and engineers. A Techni cal College in East Texas is starting a new industrial refrigeration school, and they are in need of donations. This school will be a one-year certificate program that could possibly turn into an associate degree program at a later date. They are looking for a designed small industrial two-stage system with a crossover for a single stage. The equipment used will be decided by the engineer. However, the ideal would be differing compressors and other equipment that’s industry standard in the design. We are asking for our manufacturers to help with equipment and an engineer to assist in designing a learning system. All equipment and engineering will receive paperwork from the school for tax purposes. Please note: Brands on this list are simply to illustrate the product/ concept.

experience and provide the education needed to increase their knowledge to an intermediate level. Once the candidate feels as though they have mastered the material in the book, they will be provided with the opportunity to sit for the entry level exam (not yet titled) with the end goal of the exam being accredited by ANAB, like RETA’s CARO, CIRO, and CRST exams. We truly believe this is the first step in having RSES become the Gold Standard in the HVACR world of refrigeration like RETA is in the industrial side of the industry. We are extremely excited to be a part of enhancing the knowledge of our employ ees in the workforce and empowering them for a successful career.

If you are interested in becoming involved with the process, please reach out to myself at harry@reta.com or Eric Girven at egirven@scsengineers.com. As always, I want to thank each of you who volunteer your time, energy, and expertise to this amazing committee and wish you all a blessed 2024. Thank you and God bless! Sincerely, Harry Wilkins RETA Education Coordinator

RETA & RSES As most of you are aware, RETA and RSES are under the same umbrella now, which is huge for both the industrial side as well as the HVACR side of the industry. Recently we’ve had several RETA Subject Matter Experts (SME’s) join in the RSES education meetings, which has been great in provid ing the guidance to lead the next big chapter for RSES. RSES has decided to move forward with an entry level book under the direction of the Executive Director Jim Barron, RETA staff, and committee members. The goal is to take someone with little to no HVACR

In the last issue, I presented a brief history of building and fire codes in the United States and identified the adopted codes in each state. Please note that with the publication in January 2024 of the 2024 editions of the IFC, IMC, UMC, and NFPA1, state and local jurisdictions may begin the process of updating their adopted codes. I will provide periodic updates regarding adopted codes as I receive them. In this issue, I will begin to discuss the history of the standards that have applied to ammonia refrigeration systems over the years, starting with ASHRAE15. Before we get to that, I want to explain what the difference is between a code and a standard. A standard is a docu ment containing technical guidance for various topics. For instance, IIAR Standard 2 is the standard for the Design of Safe Closed-Circuit Ammonia Refrig eration Systems. While these standards are viewed as Recognized and Generally Accepted Good Engineering Practices (RAGAGEP) by regulatory officials from OSHA and EPA, as well as from some state officials, they technically do not have the force of law behind them, until something specific happens. CODES & STANDARDS PART TWO OF MANY: BY: BILL LAPE, SCS ENGINEERS REFRIGERATION STANDARDS & CODES

FIGURE 1: ASHRAE STANDARD 15 TIMELINE

I will explain. Let’s use design standards for piping to limit our scope for now. Under OSHA and EPA regulations, a facility or company is within their rights to select the standards that they want to follow in the design of their ammonia refrigeration piping. Typically, a facility will select IIAR2 as their RAGAGEP. IIAR2 references Standard B31.5, which is the Standard for Refrigeration Piping & Heat Transfer Components published by the American Society of Mechanical Engineers (ASME). Now, this standard has been adopted by both of the model mechanical codes by reference. When this happens, and a state or local authority then adopts the mechanical code, the referenced standards become code. That is, they now have the force of law behind them. So, back to ASHRAE15. The following history was chronicled in Doug Reidl’s article, “Celebrating 100 Years of ASHRAE Standard 15,” published in the Novem ber 2014 edition of the ASHRAE Journal. A timeline of the history is shown in Figure 1. In 1914, members of the American Society of Refrigerating Engineers (ASRE), together with the New York City Fire Department, began to develop a refrigeration safety code for

the city. This new code, designed to promote the safety of refrigeration systems installed in operating within the city, required a permit to build and operate a refrigeration system and went into effect in 1915. This code set minimum design pressures for the system and required labeling of pipes, as well as many other requirements that we take for granted today. From 1915-19, ASRE worked to expand the safety standard to be more compre hensive and mold it into a more general form that could be adopted by other jurisdictions. In 1930, ASRE published Standard B9, Safety Code for Mechanical Refrigeration. When the American Standards Association (ASA), the predecessor to ANSI, approved B9 in 1932, it became the American Standard Safety Code for Mechanical Refrigera tion. It is important to note that at the time, there was little distinction between a standard and a code. ASRE published several revisions to the standard in the 1950’s, during which time, the standard was redesignated B9.1. At the end of that decade, ASRE merged with the American Society of Heating and Air Conditioning Engineers (ASHAE) to form ASHRAE, the American

Society of Heating, Refrigerating, and Air Conditioning Engineers. ASHRAE published its first update to B9.1 in 1964. By 1971, ANSI had replaced the ASA and put its seal of approval on the 1971 update to B9.1. For the 1978 update, ASHRAE redesignated B9.1 as Standard 15. ASHRAE published further updates throughout the 1980’s, 90’s and into the 21st century. It is important to note that IIAR first published Standard 2 in 1974. This edition was approved by ANSI in 1978. IIAR2 was revised and approved in 1984, 1992, 1999 (with an Addendum in 2005), 2008 (with Addendums in 2010 an 2012), and 2014. During this time, BOTH ASHRAE Standard 15 and IIAR Standard 2 applied to ammonia refrigeration systems, often leading to confusion, as there were often conflicting provisions. In June of 2018, after a formal request from IIAR, and after much consideration, ASHRAE published Addendum A to the 2016 edition of Standard 15, within which the standard committee added Section 2.3 to the standard, which stated that “This standard shall not apply to refrigeration systems using ammonia (R-717) as a refrigerant.” In addition, the addendum removed all other references to ammonia

within Standard 15, and for refrigeration systems using ammonia, it instructed the reader to refer to IIAR2. One final note to bear in mind. If a jurisdiction has not adopted a model code that references the 2016 or later edition of ASHRAE15, then it is possible that the code official for that jurisdiction may require that the facility owner and owner’s representatives (otherwise known as contactors, typically) follow ASHRAE15. This would include NFPA1, 2018 and earlier, and the IFC, UMC and IMC, 2015 and earlier. Should this be the case, facility owners or their representatives may petition the AHJ to use newer standards and codes. In the next issue, I will discuss the history of the piping standards that have, and may still, apply to ammonia refrigeration systems.

Bill is a Certified Industrial Refrigeration Operator, a Certified Refrigeration Service Technician, and is the current Treasurer of the Refrigerating Engineers and Technicians Association.

HAZARD COMMUNICATION (HAZ-COM) IS MORE THAN “SDSS” (PART 2)

14 RETA.com

B EFORE THE Globally Harmonized were several different regulations on hazard classification in use in different countries, resulting in multiple standards. The estimated amount of international buying and selling of chemicals, is about 2 trillion dollars annually. The cost of compliance with so many different systems became extremely costly and practically unmanageable. Developing of a worldwide standardized system was an opportunity to reduce cost and would improve compliance and give workers information about chemicals they work with. GHS is not new. Development began at the 1992, by the United Nations (UN), at the Rio Conference on the Environment also called 1992 Earth Summit. Various governments and other private entities agreed that “A globally harmonized system with compat ible labelling, easily understandable symbols, revising the Data Sheets, should be available by the year 2000”. In 2002 the Globally Harmonized System was officially developed and endorsed by the UN. In 2003 the first edition of GHS was published; it was originally referred to as the Purple Book. The Purple Book established hazard classification and explanations on how the system should be implemented. In 2005, OSHA announced that the Hazard Communication Standard (HCS) was to be updated and it would adopt many of the GHS components. In 2007, the Department of Transportation adopted GHS standards; they were the first United States regulatory agencies to utilize the GHS. In 2012, OSHA officially revised the Hazard Communication Standard to adapt the GHS and adopted new hazardous chemical labeling requirements as a part of its revision of the, 29 CFR 1910.1200 (HCS), As a result, workers will have more information System of Classification and Labelling of Chemicals (GHS) was created there

on the safe handling, labeling and use of hazardous chemicals. Implementation of the GHS was planned to take place over four years with key dates being: • December 1, 2013: Employers were required to train employees on how to read GHS formatted labels and safety data sheets. • June 1, 2015: Chemical manufacturers and distributors needed to complete hazard reclassification and produce GHS-compliant labels and safety data sheets. Distributors however, had an additional six-month grace period. • December 1, 2015: The grace period ended, and distributors had to fully comply with Hazard Communication Standards. • June 1, 2016: Employers were required to be in full compliance with revised HCS and completely aligned with GHS. This included training of employees on Note: Employers may discard a material safety data sheet “MSDS”, if the new data sheet “SDS” includes the same hazardous chemical information as the original MSDS formulation. If the formulation on the SDS is different, employers must maintain both data sheets for at least 30 years. OSHA standard, 29 CFR 1910.1020, With the implementation of GHS, several changes to the Hazard Communication standard were adapted. The primary changes were: • SDSs replaced MSDSs new hazards and/or revisions to workplace hazard communication program.

• Signal Words – the word “Caution” is not used in GHS • Hazard Statements • 9 Pictograms Safety Data Sheets “SDS” Prior to GHS, there was no standardized system for the development of MSDSs; there no specified number or order of sections and there were no radially recognized symbols to communicate hazards. SDSs replaced MSDSs and ushered in a standardized format. SDSs must contain 16 specific sections that must appear in the same order; with the same basic informa tion in each section. Section 1: Product and Company information • Includes product identifiers, manufac Section 2: Hazards Identification • Includes all hazards associated with the chemical and required label elements Section 3: Composition Information • Includes information on chemical ingredients and trade secret claims Section 4: First-aid Measures • Includes important symptoms, effects, acute, delayed or required treatment Section 5: Fire Fighting Measures • Includes the suitable extinguishing techniques and equipment • Chemical reactions as a result of fire turer or distributor name, address, phone number, emergency phone number, recommended use, and restrictions on use.

Section 6: Accidental Release Measures • Includes emergency procedures • Correct PPE • Proper methods of clean up and containment Section 7: Handling and Storage • Includes precautions for safe handling and storage including incompatibilities Section 8: Exposure Controls / Personal Protection • Includes: OSHA’s Permissible Exposure Limits (PEL) • Threshold Limit Values (TLV) • Appropriate engineering controls • Personal Protective Equipment Section 9: Physical and Chemical Properties • Includes the Chemical characteristics Section 10: Stability and Reactivity • Includes chemical stability and possibil ity of hazardous reactions Section 11: Toxicological Information Includes:

Section 12: Ecological Information • Includes information to evaluate the environmental impact if it were released into the environment Section 13: Disposal Considerations • Includes guidance on proper disposal practices • Recycling or reclamation of the chemical or its container • Safe handling procedures Section 14: Transport Information • Includes guidance on classification information for shipping, transporting hazardous chemicals by: Road Air Rail Sea Section 15: Regulatory Information • Includes the safety, health and environ mental regulations specific for the product that is not indicated anywhere else on the SDS Section 16: Other Information • Includes the date of preparation or last revision of the SDS

Signal Words Signal words help people immediately assess the level of risk associated with a hazardous chemical. There are only two approved GHS signal words that are to be used. • “Danger” is used when the chemical can cause an immediate “acute” serious health risk, including death or long term “chronic” health problems. • “Warning” is used when a prolonged exposure to a chemical result in health issues. NOTE: The word “Caution” is not used as a designated signal word in GHS Hazard Statements are used to describe the nature of the chemical hazard and poten tially the degree of the hazard. Example: “Fatal if Swallowed” Precautionary Statements are phrase that describes recommended measures that should be taken to prevent adverse effects from exposure to hazardous chemicals or improper storage or handling; for example, “Avoid breathing – dust/fume/gas/mist/ vapors”: Hazard Statements and Precautionary statements

• Routes of exposure • Related symptoms • Acute and chronic effects • Numerical measures of toxicity

Pictograms Pictograms are a visual system created to convey information about dangerous chemicals in a way that everyone could understand, regardless of the language they speak. Pictograms are helpful in facilities where employees speak different languages. It is even more important, however, in situations where chemicals are sent to locations throughout the world. Rather than having to put multiple labels on a container, pictograms are ideal way to communicate hazards. Pictograms are used to alert users of the chemical hazards they may come in contact with. They • Consist of a symbol on a white back ground surrounded by a red diamond. • The pictograms are determined by the chemical hazard classification. • There are 8 pictograms that are required by GHS and 1 that is optional. GHS Labels Labels are a simple task that only takes a few minutes if you have an industrial label printer. There is software that will help to radiation symbols, and many others which makes it reactively easy to print your own labels. Companies that do not yet have a label printer on site will be able to order pre-made warning symbols that can be used as needed. These premade safety symbols can come as stick on labels. When printing off custom GHS labels, they should maintain the diamond shape that has the actual image in the middle. In situations where multiple pictograms are needed for one chemical, they should be printed in a diamond shape so up to four different symbols can be placed in one area. The four-diamond layout standard is a very recognizable part of the overall GHS system. It is possible to make the pictograms larger or smaller based on the amount of space that is available on the container that is being used. create hazard signs, hazard symbols, biohazard symbols, poison symbols,

Pipe Lebling / Pipe Marking does not fall directly within the Hazard Communication Standard or in the GHS, however pipe labeling is included in the 29CFR 1910.119 PSM standard. Staying Compliant with GHS Labeling In order to be compliant, each and every GHS label on a chemical container must have the same four components: • a signal word, • a GHS pictogram, • a hazard statement, • and a precautionary statement. Each of these four components are there to effectively communicate to workers how dangerous the chemical they’re handling is, the risk associated and the proper precau tions the worker must take when working with that specific chemical. Safety Data Sheets are another important component, and these sheets are used to communicate specific hazards related to chemicals.

Chemicals play an important part in our business and likewise are a necessary part of many workplace operations. Few workplac es exist where there is not some potential exposure to hazardous chemicals. Pipe Labeling Pipe labeling is not contained in the OSHA 1910.1200 Hazard Communication Standard or the GHS. However, pipe labeling is incorporated by reference in OSHA 1910.119 Process Safety Management, from: • ANSI – American National Standards Institute and • ASME – American Society of Mechanical Engineers. ANSI-A13.1 is a consensus standard adapted by OSHA. It is intended to establish a common system to identify hazardous chemicals conveyed by piping. “Consensus Standards” are developed with the input of thousands of representatives from companies, government agencies, industry, labor, and trade associations,

consumer groups, academics, and others voluntarily participate in the development of standards through the work of approximately 240 voluntary consensus standards bodies accredited by ANSI. The inclusive ness and integrity of the ANS process encourages participation by the broadest range of subject-matter experts, resulting in high-quality standards that protect the public and foster fair commerce and innovation. When it’s all said and done, the primary goal of Haz-Com, GHS, and Labeling, boils down into one word… COMMUNICATION OF HAZARDS. The more workers know about the chemicals they handle, use and store, the better equipped they will be to work safely. The International Institute of Ammonia Refrigeration (IIAR) has issued guidance on pipe labeling of ammonia refrigeration Systems. Understanding of the GHS, allows all of us to work safely with the chemical in our workplace and in our homes. Stay tuned for Part #3: Hazard Communication at Home. What’s Under Your Sink? Many household chemicals pose the same types of hazards faced in the workplace. However, at home, there is much less training and information about chemicals and the hazards our loved ones are exposed to. Part 3 will take a look at what hazards may be lurking under the sink.

PRE-NUPS! Well I’ve heard of me some pre-nups. Heck them movie stars sign them all the time. Them NBA players wish they had signed them. And my cousin Jeb hopes he finds a girl rich enough to ask him to sign one someday. When you’re getting married, they may be great or they may be bad. I just don’t rightly know. But do you have a work pre-nup? I do know that some employers don’t believe in pre-nups with their employees. I had to do some digging to figure out what that means. I think it means the employer is not making any guarantees that you’ll have a job tomorrow. Which is strange, because I’m pretty sure they want you to guarantee you’re coming to work tomorrow, and probably the next day. The employer expects the refrigeration professional to guarantee that the technician will try to keep the system running. The employer wants the technician to guarantee that the technician will try to make sure the system runs efficiently and safely. I think the employer expects the employee to stay when a neighboring company offers an extra dime per hour. I think the employer expects a lot of guarantees. By the way, the employer has a right to expect all of these things and more.

Some employers expect employees to sign non-compete agreements. Some expect employees to sign vesting agree ments, or employment contracts with severe penalties for early termination. Some employers expect that you reimburse them for your training should you leave the company. I think all of these could be called pre-nups. So, do employees and employers have pre-nups? I think so. I think an employee should expect their employer to keep them as an employee as long as the employee is productive. I think an employee should expect the employer to try to help them be successful. I think an employee should expect that their employer won’t discriminate against them because of their sex, age, religion, height, the car they drive, or the color of their hair. I think the employee should expect to be treated with respect. I think that a good productive employee should expect a job as long as their employer is capable of providing one. I think employers should expect good employees. Over a hundred years ago, David Brown spoke of the employee, employer, customer triumvirate, that’d be a three-legged milk stool. It’s as true today as it was then. In order for any company to be successful they need

employees, employees need jobs. Jobs provide money for employees to buy what they need, which probably includes their employer’s goods or services. By selling their goods or services, the employer can pay their employees. It all works together. It’s the “circle of business life”. When the pre-nups between employers and employees are mutually beneficial, we can accomplish great things. So I believe in pre-nups. I hope you do too! The shade tree grows outside of the little town of Broughton, Ohio. Where everyone is always welcome, the beer is always cold, and something is always needin fixin.

OZZY OSBOURNE’S POOL By Arlie Farley During the heat wave in 2019, singer Ozzy Osbourne’s home pool was too hot, so he decided to purchase a truck load of ice to cool it down. They delivered 3,000 lbs. of block ice to his house and dropped them in the pool to cool it off. Apparently, it backfired. 10 of the 300 lb. ice blocks only dropped the degrees, and his wife Sharron would not allow him to buy any more ice to drop the temperature further. I guess he should have talked with a refrigeration tech and we would have told him a BTU is a BTU and 10 of the 300 lb. blocks in a pool is like 10 ice cubes in a 5-gal bucket. Not going to do anything. I had my brainiac brother Jake Farley run the numbers. Going backwards I estimate 1 pound of ice at 200 BTU’s potential. 3,000 pounds is equal to 6 million Btu’s / 3* temperature reduction/ 8.34 pounds of water per gallon indicates that Ozzy’s pool should be approximately 24,000 gallons.

The Refrigeration Historian Volume XXXI

While it did not make national headlines, March 10, 2022 marked the 10th anniversary of the death of Sherwood Rowland, more precisely F. Sherwood Rowland. If you are unfamiliar with the name of F. Sherwood Rowland, never fear. You have probably praised him or cursed him without ever knowing his name. Perhaps it says something of the human condi tion that one’s work can stir such emotion in others. Frank Sherwood Rowland, or Sherry as he was called by friends, forever changed the refrigeration industry. He was responsible for the “death” of CFCs, and even though it never went away, and the rebirth of ammonia.

Sherry was the middle son of an Ohio Wesleyan Mathematics professor. He was born June 28, 1927 in Delaware, OH and was an extremely gifted student, having graduated high school at the age of 15. A gifted athlete as well as scholar, Sherry played Varsity Basketball and semi-pro fessional baseball. Sherry studied at Chicago University. He then trained as a Navy radar operator and served during World War II. After leaving the Navy, Sherry started his career at Princeton University as an instructor. He would stay at Princeton from 1952 through 1956. In 1956, Sherry would relocate to the University of Kansas where he would be an assistant professor until 1964.

Sherry began his career as a full-time professor of Chemistry at the University of California in Irvine in 1964. It’s important to remember that the ’60s were a very volatile time at American universities. A social revolution was underway, and political studies and protests predominated campuses across the nation. In this backdrop, Sherry conducted revolutionary work in the traditional field of chemistry during the political hotbed that was the California college scene. Perhaps this makes his work even more remarkable. He contin ued in this position until his death in 2012. A favorite quote concerning the gravity of Sherry’s work was a comment he made to his wife during his research.

When asked by his wife how his research was progressing he said “The work is going very well, but it looks like the end of the world.” Sherry was an atmospheric chemist who won the Noble Prize in Chemis try in 1995 with colleagues Paul Crutzen, an atmospheric chemist, and former student Mario J. Molina, “for their work in atmospheric chemistry, particularly concerning the formation and decomposition of ozone.” His 1974 paper “Chlorofluorometh anes: Chlorine Atom-Catalysed Destruction of Ozone,” co-authored with Mario Molina, was cataclysmic to the synthetic refrigerant industry. It was published in the British journal Nature. It did not receive immediate acclaim. Sherry warned the world of the destructive consequences of CFCs on the ozone layer. This brought to light the potential destructive hazards of ultraviolet rays that could enter the atmosphere through the holes in the ozone layer, which could ultimately cause skin cancers on a massive scale. The hole in the ozone layer was discovered by a British Antarctic Survey in 1985. NASA would confirm the findings a few months later. The good news is that since the discovery, evidence has come to light, the ozone layer is actually repairing itself. Though repair is a decades long process. Sherry’s work ushered in the founda tion of the Montreal protocol, banning R-12, as well as R-22 and other CFCs. This assured his place in refrigeration history.

Sherry was well thought of by his colleagues. Many noted that he made time for all those who sought him out, whether an esteemed colleague or a new student. Barbara J. Finlayson-Pitts was quoted as saying: “He was a scientist of enormous integrity, who really did change our world for the better.” Per his longtime friend and colleague, and daily conversationalist, Don Blake: “His exemplary scientific rigor, honesty, dignity and collegiality made him a role model to emulate in the heat of today’s politically charged science debates.” Bassam Shakhashiri noted, “Sherry Rowland will live on as a compelling reminder that individual scientists must speak out with courage and persistence when they think it is important for society to change.” Sherry wasn’t without his detractors and pseudo enemies. Many in industry disputed his findings, some for financial reasons, some for lack of understand ing, and some though fear of what the ramifications of his conclusions would mean. One industry consultant accused him of being an agent of the KGB. His acclaim was global. In 1978, he was elected to the National Academy of Sciences. In 2004, 32 years later, he was made a Foreign Fellow of the Royal Society, the world’s oldest independent scientific academy dedicated to promoting excellence in science for the benefit of humanity. He also won the Japan Prize Foundation’s Japan Prize for “original and outstanding achieve ments in science and technology that are recognized as having advanced the

frontiers of knowledge and having served the cause of peace and prosper ity for mankind.” Sherry was called to our Lord on March 10, 2012 on his 84th year. He died of Parkinson’s complications, a disease worthy of much more research. He passed at his home in Corona Del Mar, CA. He was survived by his wife of more than 60 years, Joan and their son Jeffery Rowland, daughter Ingrid, and two grandchildren. To put into perspective his contribu tions, his Wikipedia page has received more than 60,000 page views. His biography is available in 46 different languages. Wikipedia notes he is one of the 250 most popular chemists of all time. Information for this article included information from various newspaper articles, historical notes, and articles.
