IIAR Recognized for Standards Development

With the completion of IIAR-2 – the first comprehensive standard for the safe design of ammonia refrigeration systems – along with a companion suite of IIAR standards addressing installation, commissioning, operations and decommissioning, IIAR has evolved to become internationally recognized as a standards development organization, or SDO, said Jeffrey Shapiro, P.E., IIAR’s code consultant and president of International Code Consultants.

Applying Natural Refrigerants to New Applications

Is it feasible to apply lowcharge ammonia technology in an application that has traditionally been dominated by the use of HFCs and other synthetic refrigerants? That’s what a big-end user wanted to know when it approached Azane Inc., a package supplier based in California, to manufacture a lowcharge ammonia chiller that provides chilled water to a HVAC air conditioning system.

EPA Issues Proposed Rule on RMP

On March 14, 2016, the Environmental Protection Agency (EPA) published in the Federal Register a proposed rule to modernize the Risk Management Program. The rulemaking comes as a part of the Obama Administration’s efforts to implement Executive Order 13650 – Improving Chemical Facility Safety and Security. The Executive Order was issued in response to an incident at a fertilizer plant in West, Texas in April 2013.

Evaluating Safety in CO2 Systems

The use of carbon-dioxide refrigeration systems has been gaining in popularity in recent years as an alternative to ammonia systems, as companies learn about their energy efficiency, safety benefits and resiliency. Although CO2 , like ammonia, is classified as a “natural refrigerant,” there are a number of differences between the two refrigerants, related to the significantly higher operating pressure of CO2 systems that are critical to understand from a safety perspective.

Qualifying Ammonia Refrigeration Contractors

Business owners and operators must take steps to ensure that contractors working on or near ammonia refrigeration systems have the necessary qualifications and work experience to help employers understand their responsibilities related to ammonia refrigeration contractors, and demonstrate their proficiency in working with the system, Tony Lundell, IIAR director of standards and safety said. Lundell led an IIAR webinar in April entitled, “Qualifying Ammonia Refrigeration Contractors.”

IIAR Submits Formal Questions on Eyewash, Safety Showers

The revision of IIAR-2 involved discussions of many philosophical and practical matters. Among the topics discussed was that of the need for eyewash/safety showers in areas other than machinery rooms, and specifically in cold environments such as a freezer or on the roof.
