RC&E Chill – Industrial Refrigeration and Process Safety / Risk Management. Upon approval by the ANSI Board of Standards Review, the standard will receive a different name that reflects this approval date. IIAR is a technical member organization with industry representation from all facets of the natural refrigeration community, including manufacturers, engineers, contractors, end-users, academics, scientists, trainers, and more… IIAR 9 §7.3.12.2 requires setpoints of 50 ppm and 1,000 ppm respectively. Quantity: Quantity is required. Overview of IIAR Standard 9 Overview of IIAR Standard 9 von Peter Thomas vor 9 Monaten 5 Minuten, 40 Sekunden 326 Aufrufe This video provides an overview of , IIAR 8 didn’t change much, but this was a very significant change to the existing IIAR 4 standard. hearing from you. IIAR 2 §7.2.3 requires ammonia detection to be installed in areas “other than machinery rooms” when ammonia equipment is installed indoors. IIAR Ammonia Refrigeration Piping Handbook.Provides is a tutorial and reference book that represents the collective efforts of the most knowledgeable specialists in the ammonia refrigeration industry. American National Standard for ANSI/IIAR 7-2013. While it has long been recognized that new systems must adhere to the requirements of IIAR Standards 2 and 4, facilities with existing systems have often been confused on how they should relate to these standards. To that end, I’ve converted every requirement in IIAR 9-2020 to a Checklist and included that checklist in with the existing PHA checklists for IIAR 2 compliance. IIAR 2 §6.14.3 requires that machinery room exhaust be to the outdoors not less than 20 ft from a property line or building opening at a velocity of at least 2,500 ft/min. IIAR 9 does not require detection outside of a machinery room. How do you build a defensible case that your system built to an older code or standard is still designed, maintained, inspected, tested, and operating in a safe manner if it doesn’t meet the current code or standard? Why use the “buddy system” during Line Openings? You could save: 41.2%. Check the template change-log for details. IIAR 9 has no such requirement. IIAR 2 §6.11.2 requires manual control of machinery room lighting. process safety management program or Please contact us today. [Section 3.3.2 (c) of ANSI/IIAR 2-1992 and Section 9.8 of ANSI/ASHRAE 15-1994] If the discharge of the pressure relief device is vented to atmosphere, it shall be piped in accordance with Sections 3.11.4.11 and 3.11.4.12 of ANSI/IIAR 2-1992. Post was not sent - check your email addresses! The safety focus is on persons and property located at or near the premises where the refrigeration systems are located…. In SHORT, here’s what you need to know as an end-user: For current/future projects that involve the installation, startup, and commissioning of new equipment, use the “IIAR 4 APP-B Checklist Tracking Log Template” to manage adherence to IIAR 4 before, during, and after the installation. Ammonia Week in Review | January 15, 2021, 2021 California CUPA Conference (Virtual), IIAR 2 §4.2.3 allows certain equipment (evaporators, condensers, low-probability pumps, valves, etc.) While it has long been recognized that new systems must adhere to the requirements of IIAR Standards 2 and 4, facilities with existing systems have often been confused on how they should relate to these standards. IIAR 2 §5.14.5 requires all equipment to be supplied with a nameplate. IIAR 9 does not include these requirements. We recently posted a video series which provides a summary of the content in Standard 9, but wanted to add a final blog to summarize differences between ANSI/IIAR 2-2014 Addendum A and ANSI/IIAR 9-2020. © 2021 Resource Compliance.
