ALARM FLOODING is the phenomenon of presenting more alarms in a given time period than a human operator can effectively address. A significant finding of a 2006 research project of the Abnormal Situation Management (ASM) Consortium (www. asmconsortium.net) was that even though configuration techniques can significantly reduce the size of the alarm flooding associated with process upsets, these techniques on their own don't suffice to reduce the alarm loads to a level at which human operators can mentally process and physically respond. A key need that remains is to provide effective alarm summary displays to help operators cope with these inevitable alarm floods.
