This course provides a practical foundation in the engineering calculations that underpin regulatory compliance for industrial refrigeration systems. Participants will learn how to estimate refrigerant inventory, design safety relief and ventilation systems, perform mass and energy balances, and model atmospheric dispersion for off-site consequence analysis. Whether you're managing an existing PSM/RMP program or designing new systems, this course ensures you can confidently support documentation and decision-making with sound engineering principles.
If you answer “no,” to one or more of these questions, this course is for you:
Do you have a sound estimate of the total inventory of refrigerant in your industrial ammonia refrigeration system?
Have you properly documented the basis of design for your safety relief vent system(s)?
Have you prepared mass and energy balances for the parts of your refrigeration systems constructed after May 1992?
Do you have established methods for estimating the quantity of refrigerant lost by your system in the event of a leak?
Do you understand the fundamental principles of the atmospheric dispersion modeling required by RMP?
PSM coordinators and EHS professionals responsible for regulatory compliance.
Refrigeration engineers, supervisors, and experienced operators involved in ammonia systems.
Consulting engineers and design professionals working on industrial refrigeration projects.
What You Will Learn
Perform key engineering calculations for refrigerant inventory, safety relief systems, and ventilation design.
Apply mass and energy balances and estimate release quantities for incident scenarios.
Understand and utilize dispersion modeling techniques for RMP off-site consequence analysis.
