A safety monitoring system is provided for a pneumatic control system having a double safety valve arrangement. The monitoring system is adapted for preventing further operation of the control system in response to a malfunction of either the double safety valve or the monitoring system itself. The monitoring system preferably includes constantly dynamic monitor valves, and also preferably includes a damper feature for substantially preventing premature, undesired shutdowns of the control system in accordance with predetermined system parameters.
