The Dynasafe SDC2000 has also demonstrated the ability to process the types of munitions associated with Requirement BG-2. DEs are high enough, although they have not been demonstrated with the proposed new air pollution control system. Reliability has been good during the operations in Germany. The system is not transportable.

HAZOP is used to identify the design, operating, and quality problems related to planned process. Operational problems generally come from human error, operating procedural error, or from equipment/control system reliability issues. HAZOP is well suited for such applications.
