OSHA has recognized Design Institute for Emergency Relief System (DIERS) methods as good engineering practice for process safety management of highly hazardous materials. If you’re responsible for the safe handling of the effluent from relief systems, this advanced course will teach you how to apply the DIERS techniques for providing adequate pressure relief for runaway reactions and other pressure-producing events. If you are just starting out, take the basic course on the topic (CH172).

Applying DIERS Technology in Your Facility

This course covers the Design Institute for Emergency Relief Systems (DIERS) techniques for providing adequate pressure relief for runaway reactions and other pressure-producing events that result in two-phase flow.Each participant receives the texts: Emergency Relief Systems Design Using DIERS Technology (published by AIChE), and Guidelines for Pressure Relief and Effluent Handling Systems (published by CCPS and includes CCflow computer routines).
