If You Do Not Measure, You Cannot Manage
[Alarms]
You've heard the phrase, "Too many alarms", but how many alarms is too many?
Measurement of alarm behavior is integral to good alarm management.
This month's technical doc discusses the origin of the EEMUA®
benchmarks in alarm performance assessment, and summarizes
them for your reference.
A brief abstract:
A joint research effort between the
EEMUA® and the ASM® Consortium established a comprehensive guide to best practices in alarm management, including
target metrics for alarm activity. The document, EEMUA Publication 191, Alarm Systems: A Guide to Design, Management,
and Procurement, or "EEMUA 191", is the current "de facto" standard for alarm management.
The EEMUA alarm performance targets were established through extensive human behavior studies. By observing the time
required to respond to different categories of alarms and accounting for that within the other demands of an operating team,
the group was able to establish alarm activity targets and other protocols that maximize operator capabilities while
mitigating stress. The result is fewer upsets and an operating team that can successfully reverse upsets when they occur.
Clear communication of plant condition and enhanced responsiveness of the operating team results in additional capacity
without compromising safety, tangible benefits to business performance and corporate vigilance.
