RETA certification

October 9, 2023

Jim Barron RETA, executive director is located on the far left while Bengie Branham, current national president of the US-based Refrigerating Engineers Technicians Association (RETA) is located on the far right.


August was an exciting month for the Risk Management group at SCS Tracer Environmental, a practice of SCS Engineers. Bengie Branham, one of our inspectors and trainers, is the current RETA President. In that position, he and Jim Barron (RETA executive director) went to South Africa to attend the second annual GCCA African Cold Chain Conference in Cape Town. This visit aimed to promote RETA’s mission of training ammonia refrigeration operators to ensure they have the most current education to be safe and efficient. RETA is the only organization globally with ISO, ANSI, and ANAB accreditation. They currently have a total of 24 Authorized Instructors (RAIs). SCS Tracer Environmental has 5 RETA Authorized Instructors.

There were many discussions about energy security and conservation. The electrical grid is very degraded and not reliable. Many facilities used generators during the load-shedding period, forcing multiple starts on a system. Another alarming metric was that over 40% of field produce was wasted before entering a facility due to temperature and storage failures.

While the U.S. may struggle to address problems with its transportation infrastructures, RETA hopes to help address the educational skill gaps. Many participants at the Conference showed a willingness to embrace new ideas and solutions. One of the items RETA will work with is forming the RETA Chapter in South Africa. Local Chapters are a great way to assist in learning, networking, and sharing ideas. There is at least one Chapter in every state and 13 different countries.

Bengie was impressed with the vast amount of resources and opportunities available on the continent, but high unemployment and other barriers prevented this potential from being fully realized. He hopes that addressing the skills gap will assist many in the population. At the Conference, he felt that many surrounding African countries were committed to providing and operating safe and efficient ammonia refrigeration systems, an exciting outreach with a multitude of opportunities.

SCS Tracer Environmental is a strong supporter of RETA and its mission. Along with the 5 RAIs, we also have three past, one current, and (at least) one future RETA President. Now, on to Jacksonville for the 2023 National Conference!

Congratulations, Bengie.


That turkey doesn’t get to the table without a lot of help. the Refrigerating Engineers and Technicians Association (RETA) is the most recognized organization in the country dedicated to the professional development of industrial refrigeration operators and technicians. These are the people who help keep food cold and safe! SCS Engineers recently celebrated two SCS Tracer professionals at RETA’s 2021 National Conference.

Thanks, Eric!

Eric Girven was honored with the Guy R. King Memorial Award for his outstanding performance educating and training RETA members to operate ammonia refrigeration systems safely and efficiently. Mr. Girven is a Project Manager and an Ammonia Refrigeration Advisor in SCS’s Tracer Environmental practice. Very active in RETA and the International Institute of Ammonia Refrigeration, Eric is an industrial refrigeration process safety management, risk management, and energy management, expert. He conducts mechanical integrity inspections, process hazard analysis, compliance audits and is a certified industrial refrigeration instructor.

Bengie Branham, pictured above, joins Daryl Davis, Eric Girven, and Gene Dumas as RETA Authorized Instructors. Our SCS colleagues are highly qualified trainers for RETA’s credentialing program. There are only 23 RAI-certified trainers in the country. Each works tirelessly to help operators and technicians learn and certify themselves to run ammonia refrigeration systems safely.  Learn more about education and certification here.


We’re proud of our fellow SCSers and thankful to work with them as they protect the health and safety of others while getting food safely to your Thanksgiving dinner table and to those in need. Happy Thanksgiving!

SCS Project Director, Bill Lape, is an expert in the development and deployment of standardized Risk Management and Process Safety Management programs, including process safety program implementation and support to manufacturing facilities that utilize ammonia as a refrigerant.



That’s Bill Lape in a word. 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 – RETA. He is also a certified Process Safety Management Professional through the University of Wisconsin.

and he’s a wonderful writer. Here are two of Bill’s most recent articles.


PSM SAFETY & COMPLIANCE CONSIDERATIONS IN THE AGE OF PANDEMICS  PSM safety programs and training remain a top priority during the pandemic. While online training is not a complete substitute for live, face-to-face PSM training and instruction, in the age of pandemics, it is a viable option. What to look for in PSM – ammonia refrigeration system safety training?

EPIC FAIL: ICE BUILD UP  When developing your inspections for your system’s mechanical integrity program, always be mindful of the potential consequences of ice buildup, particularly if it continues for an extended period of time.
