Top 10 Alarm Management Tips for Process Control
Engineers
One of the great successes in process
manufacturing has been alarm management. As the
industry shifted to computer-based control
systems, they were quick to understand the
dangers posed by the rise of mismanaged alarms.
Best practices in alarm management, industry
acceptance and an industry standard for the
process industries quickly emerged. Alarm
principle documents were created in-house by
operating companies and transparent alarm
management systems and alarm rationalization
efforts were established. A set of standards was
created, and they were used extensively. They're
now employed all across the process sector to
maintain alarm systems updated. Going forward,
companies have created secured master alarm
databases and management of change (MoC)
procedures for alarm management service-related
changes. From the operations console through
engineering and management, the necessity of good
alarm design and alarm management system is
acknowledged in the industrial process culture
today. This also includes the basic principles in
accomplishing these. This is how business is
supposed to work. Despite this progress, the job
of alarm management is not yet over. Alarms have
a life cycle that demands some maintenance and
auditing on a regular basis. Many companies are
unclear about how to proceed after surviving the
initial challenges. They are hesitant to repeat
alarm rationalization, as the five-year audit
cycle recommends, but they do want to

ensure that their accomplishments and benefits
are everlasting. This article gives ten
suggestions for resolving this issue and defining
a course for long-term alarm management. Top 10
Tips to Improve Alarm Management Tip 1
Identifying the Owners for Every Alarm Including
Highly Managed Alarms. Owners should be
identified for all alarms, not just those that
are well-managed. Some alarms are "highly
managed," as was recognized in the early days of
alarm management mainly particular safety,
environmental, or mechanical integrity alarms.
With the passage of time, the process industry
has understood that all alarms require the
presence of an owner and an MoC. Assigning alarm
owners permits alarms to be managed in large part
by their respective owners without requiring the
complete alarm management team to gather. Tip 2
Alarm Rationalisation (AR) Do Not Necessarily
Mean Extended Meeting Long AR meetings can be
reduced or even eliminated in a variety of ways.
While having the complete team in one room to
analyze every alarm can be beneficial, many
people now believe that it should be a one-time
transaction due to the increased availability of
huge teams of high-demand professionals. To keep
the results evergreen, we'll have to make do
with the results of that endeavour, as well as
various best practices. Mini-AR meetings
connected with process modifications, project AR
meetings incorporated in project scopes, and
continuing (weekly) metric-driven alert bad-actor
remediation techniques are examples of these
best practices. Tip 3 Operators Have a Veto
Power There's a concept known as "good to know."
If there is no specified action for the operator
to do, there should not be an alarm in the first
place, according to an early alarm management
maxim. However, operators in the room will
frequently argue that some alarms are important
to be aware of, even if no urgent action is
required. Alternatively, certain alarms are so
troublesome that they should be removed
regardless of their intended purpose, because
the alert will be silenced or defeated (in some
way), or it will become a nuisance. In such
circumstances, it's up to the engineers to come
up with a better solution by recognizing a
different type of alert or using one of the
various alarm design tools and techniques
available, such as filtering, delay, dead band,
dynamic alarming, and so on. Tip 4 Alarm
Priority is Twice Severity of Consequence and
Once Time To Respond (TTR) Since the
severity/time matrix has long been a staple of
alarm management, it frequently adds more
ambiguity than usefulness. Alarms are prioritized
by operations and engineering professionals
based on the severity of the probable
repercussions. They want to know and
3
respond quickly in potentially high-severity
situations. When it comes to alert priority, this
technique is a direct translation from severity
to top priority. Regardless of the time, it is
less unclear, takes less time during AR and more
accurately reflects operations' safe
instincts. Tip 5 Alarm Rationalisation (AR)
Isnt About Removing Alarms One of the most
important aspects of alarm rationalization has
been the assumption that one of the key goals is
to remove (delete) programmed alarms. Many
individuals today recognize that this is
incorrect. Alarms are set based on the
requirements of each process, with no
predetermined quantities. Whenever it comes to
excessive alarms, the number of alarms that
occur is more relevant than the number of alarms
that are configured. Tip 6 Get an Alarm
Configuration Procedure Document Control system
and alarm design consistency are one of the most
important operational and engineering aids. The
company alarm principles document might define
guidelines (or standards) such as alarm design
for routine level controllers or safety function
pre-alarms. As the guideline document expands,
the number of alarms that need to be individually
reasoned decreases. This allows firms to focus
resources on the alarms that demand specific
attention, resulting in greater consistency and
efficiency. Tip 7 Combine Knowledge of Design
Conditions Every alarm rationalization analysis
should also include knowledge about constraint
boundaries and historical trends. This is the
information required to arrive at effective alarm
settings rapidly. Alarms are typically designed
to envelop design conditions or prevent
constraint limits from being exceeded. If a
historical pattern of actual values shows that
such a setting isn't available without
occasionally becoming a standing alert,
mode-based alarming may be required. Tip 8
Strengthening the Value of the AR Results Give
access to those who require it at the time they
require it. While AR finds the relevant alarms,
settings, and priorities, it also creates useful
data such as potential consequences and
operational replies. Make this information
available at the operations console, preferably
with a single click on the alert itself within
the control system. Tip 9 Integrating Metrics
and Ongoing Remediation Practises Even if an
initial AR has not been completed, deploy metrics
and continuous bad-actor remediation methods.
Without an initial AR meeting, consistent
metric-driven repair techniques can eventually
lead to a healthy alarm system and reach Level 4
or Level 5 performance. Tip 10 Alarm
management Accounts for Operational Stability and
Efficiency More the Safety Safety systems, not
alarm systems, are ultimately responsible for
ensuring safety. Alarm management development is
frequently hampered by the belief that it must be

• rigorous. In other words, applying a more
  comprehensive safety system evaluation to alarm
  management, results in unrealistic resource
  demands, given the large number of configured
  alarms in many facilities. While process hazard
  analyses and safety systems may dictate some
  alarms, alarms are mostly used to improve
  operational effectiveness. As a result, it is
  virtually the best treated, recognizing the
  limited resources available and the actual role
  of alerts in operation.
• Moving Ahead
• To date, the image of an unpleasant lengthy alarm
  rationalization meeting has arguably
  best-reflected alarm management practice. That
  stage is basically passed in the industry. The
  following factors can be used to create an
  effective and efficient alert management
  approach in the future
• Continuous bad-actor remediation and automated
  metrics
• Integration of the control system (bring AR
  results to operators in context)
• A paper that should cover the majority of alerts
  as a guideline.
• Ownership of all the alarms.
• Consider alarm management as a technique for
  improving operational efficiency.
