Why We Need Effective Alarm Management?
2
Introduction

• Alarm management is essential for ensuring the
  smooth operation of industrial plants in order to
  make them safer and more reliable. Alarms, on the
  other hand, if poorly controlled, can jeopardise
  plant safety and have a detrimental influence on
  process industry performance and profitability.
• To maintain the smooth functioning of their
  operations and to satisfy industry standards,
  companies rely on the effective handling of
  process alarms.

3
Why Do We Need Alarm Management?
The goal of an alarm management programme is to
mitigate, prevent, and minimise the consequences
of unusual events. Processes and methods for
recognising, recording/documenting, designing,
monitoring, and maintaining triggered alarms from
process automation systems, such as automated
Safety Instrumented Systems, are included in
alarm management.

• Over time, systems have grown to include numerous
  control systems, as well as IoT, AI, and other
  technologies. All of this is increasing the
  frequency, complexity, and volume of alerts and
  events, which has the potential to create a
  dangerous environment in control rooms and remote
  operations centres.

Alarm Management Problems

• Nuisance Alarms
• Stale Alarms
• Operator Response
• Alarm Floods
• Frequent Alarms
• Suppressed/Disabled/Shelved Alarms
• Master Alarm Data/Variable Table

5
Signs of Poor Alarm Management

• Suppressed or disabled alarms
• No alarm despite the occurrence or possibility of
  any event
• Poorly set alarms causing nuisance
• Frequent alarm flooding causing confusion and
  mismanagement
• Slow response due to missing alarms or alarm
  fatigue
• No clear reason for alarm

6
Signs of Good Alarm Management

• Recognizes and solves actual problems in a timely
  manner.
• Identifies the appropriate data to allow an
  operator to act safely.
• Increases the efficiency of the operator
• It safeguards the plant's machinery and
  processes.
• Losses and downtime are reduced.
• Allows for a better understanding of the plant's
  status and operation.
• Gather information and compare your system to
  others.
• Perform documentation and rationalisation of
  alarms.
• Implement an alarm audit and make sure that
  technology is in place.
• Implement alarm management in real time.
• Maintain and control your enhanced system.

Alarm Rationalisation. What Is It?

• It is the process of assessing one alarm at a
  time against the concepts and design of safety
  standards within the plant.
• The first step in rationalisation is to determine
  the appropriate alert level for the appropriate
  signal and response.
• The alarm is then prioritised based on the
  severity of the consequences and the time it
  takes to respond (at all not to be
  underestimated).
• Few "bad alerts are frequently to blame for
  unusually high process alarm rates.
• Instrument problems, bad DCS/SCADA configuration,
  or poor process design all contribute to these
  warnings.
• Excessive alarms to operators provide an active
  impediment to their capacity to act successfully,
  as well as a culture of alarm acknowledgement
  without action.

Performance Metrics for Alarm Management

• Alarms per day
• Alarms per 10 minutes
• Alarm flood analysis
• Most frequent alarms
• Chattering alarms
• Alarm Priority Distribution
• Stale Alarms

9
Benchmarks for Proper Alarm Management

• Less than one alarm per 10 minutes very likely
  to be acceptable
• One alarm per 5 minutes Manageable
• One alarm per 2 minutes Likely to be very
  demanding
• More than one alarm per minute Very likely to be
  unacceptable

Process safety analysis is given a lot of
attention these days, but alarm management must
also be part of the overall plan to operate
safely, and should be benchmarked. They are as
follows

Guidelines For Alarm Improvements

• Identify and rectify misconfigured alarms
• Create proper alarm settings
• Ensure consistency in alarm settings
• Eliminate duplicate nuisance alarms
• Ensure meaningful alarm priorities
• Document alarm information for operators
• Create master alarm database
• Adjust alarm dead band settings

Many alarm management companies like SAROM GLOBAL
will evaluate every alarm configured on the
system on a regular basis, looking for areas
where improvements may be made.
