Control Room Protection

A process control building should contain the facilities and offices essential to process control. It should not be located in a structure with unrelated functions such as administration, accounting, engineering, and research laboratories. Where central control buildings include analytical laboratories or kitchens, consider the provision of a firewall to separate these areas from the process control areas. It is advisable to construct a control building with no equipment located above or below the control room. Where central control buildings house the emergency control center, consider the building location and the location of the personnel expected to staff the emergency control center.
