One hundred nine companies have formed the DIERS Users Group, a Design Institute of the AIChE, to cooperatively assimilate, implement, maintain and upgrade the DIERS methodology. The purpose of the group is to
reduce the frequency, severity and consequences of pressure producing accidents
develop new techniques which will improve the design of emergency relief systems.
Membership in the DIERS Users Group offers access to refinements of the DIERS technology, participation in development of additional technology, and an opportunity to share learning experiences. Membership is open to industrial or engineering organizations interested in the design, use or manufacture of emergency relief devices and systems. Semiannual three-day technical meetings are held at various locations and feature technology presentations by member company representatives and invited speakers and discussion of the results of computational example problems and experimental round robins. There are no fees for participation.
