RMP Rule Changes Resulting from the SCCAP Rule

The Environmental Protection Agency has issued proposed rule changes to the Risk Management Program Rule as part of the Safer Communities by Chemical Accident Prevention Rule. The final rule provisions took effect on May 10, but there are future phase-in dates for some provisions. Douglas Reindl, a professor of mechanical engineering at the University of Wisconsin-Madison and the founding director of the Industrial Refrigeration Consortium, provided an overview of the rule during IIAR’s annual meeting.

President’s Message by Gary Schrift

The months after IIAR’s annual conference are always think about the next membership year ahead. While there’s always a lot going on in these last few days of summer, it’s nice to pause for a moment and reflect on what it means to be an IIAR member and what new plans we have for the future.

Work Continues on IIAR Standards

The Standards Committee is continuing its work on revisions of several standards, which must be reviewed and revised a minimum of every five years by the American National Standards Institute (ANSI) for IIAR to remain as an accredited Standards Developing Organization (SDO). Updates for each standard were given during the IIAR Standards Committee Meeting at the IIAR 2023 Annual Conference in Long Beach.

Update on IIAR Standards: 2023

IIAR is the world’s leading advocate for the safe, reliable, and efficient use of ammonia and other natural refrigerants as well as an ANSI-accredited standards developer. IIAR is currently the only organization writing design and operation standards specifically for ammonia and other natural refrigeration systems. All IIAR Standards are developed to meet essentialrequirement criteria set by ANSI. All IIAR Standards must be re-affirmed every 5 years.

Code and Standards Road Map Overview

Alot has happened since 2019. IIAR, in its continuing mission to promote the safe and sustainable use of natural refrigerants, produced the ANSI/IIAR CO2-2021 Safety Standard for Closed-Circuit Carbon Dioxide Refrigeration Systems. As the phase-down of F-gas refrigerants continues to accelerate worldwide, CO2 technology has become an increasingly popular option utilized in the industrial refrigeration sector and more recently in the commercial refrigeration sector.

Bridging the Gap: IIAR’s Newest Standard to Address Hydrocarbons in Industrial Refrigeration

IIAR is nearing the completion of its first standard for hydrocarbons—such as propane and butane—in large refrigeration systems. Hydrocarbons have been used for years in the petrochemical industry and are increasingly used in some refrigeration applications.

IIAR Continues Work Updating and Developing Standards

IIAR is known for its development of standards, and to date, IIAR has published nine ammonia standards and one CO2 standard. Per ANSI requirements, each standard must be updated at least every five years.

Costa Rica Moves on Mandatory IIAR Standards

All IIAR standards, including the Carbon Dioxide standard, ANSI/IIAR CO2, have been adopted within Costa Rica on a voluntary basis as National Norms, and the country is moving forward with its plans to make the standards mandatory. The next step is to prepare and educate industry professionals in the country on IIAR standards before the mandate takes effect.

IIAR Releases Updates to IIAR-1 and IIAR-3 Standards

IIAR reviews and updates existing standards every five years for periodic maintenance and has recently released updates on IIAR 1 and IIAR 3. The periodic maintenance reviews and updates meet the “Procedures for the Development of IIAR Standards for ANSI Approval” and ANSI’s Essential Requirements.

IIAR Improves Safety and Operations with Ongoing Research and Standards

As the world's leading advocate for the safe, reliable and efficient use of ammonia and other natural refrigerants, research is a critical component of IIAR’s work. IIAR’s ongoing research projects lead to improved safety and more efficient operations while also shaping industry standards.

IIAR Standards: A Look Back

Bob Czarnecki can’t remember exactly when he started as chairman of IIAR’s Standards Committee, but he thinks it was 10 to 12 years ago. “The former chair had some medical issues, and I was filling in for him. So, I’m blurred as to when I started,” Czarnecki said. “When I first started, the mandate was to develop, maintain and interpret standards. At the time, we had two standards that were ANSI approved. Since then, we have developed eight other standards that have gotten ANSI approval.”

International Fire Code to Defer to IIAR for Ammonia Issues

After years of work, it is more than likely that all code bodies will now refer to IIAR for ammonia refrigeration requirements by 2024. IIAR has made significant progress towards this goal over the past 20 years, but there was one outlier—the International Fire Code. However, the IFC’s technical committee has approved a proposal for the 2024 edition of its model code, deferring all matters related to ammonia refrigeration to IIAR.

CO2 Standard Provides Guidance on Growing Segment of the Industry

The International Institute of Ammonia Refrigeration has released its safety standard for CO2 closed-circuit systems. The standard covers all phases of the CO2 system lifecycle, from design, installation, and start-up to inspection, testing, and maintenance. It encompasses the CO2 portion of a cascade system, systems using CO2 as a secondary fluid, systems operating part- or full-time in the transcritical cycle, and heat pumps.
