EI members represent all serious stakeholders in emergency interoperability and communications from both the public and private sectors. The EI member roster comprises a diverse collection of organizations and individuals that touch the worlds of emergency management, Incident Process Management (IPM), Business Continuity (BC), and risk management.

If you are involved with, use, or offer products or services for any of these areas, then you should participate in EI. Everyone is welcome to join, and anyone employed by an existing OASIS member may participate in EI without additional dues or cost.
