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