What is Alarm Management and Why is it Important?

• The Purpose of Alarm Management
• Alarm Management defines the line between a
  process's normal and pathological states. Alarms
  provide a layer of protection against dangerous
  scenarios by alerting operators to take remedial
  action to restore the process/control loop to
  normal conditions.
• Corrective actions typically relied on human
  involvement and are thus constrained by factors
  like operator knowledge, training and standard
  operating procedures. This corrective action
  must be conducted within a particular time frame
  to avoid process disruptions or endangering the
  plant's or personnel's safety.
• Automated process safety systems (SIS/ESD) are
  the final line of defence. These safety systems
  are programmed to operate without the need for
  human interaction. As part of a standard process
  control system, alarms are issued for operators
  to take action however, if the process cannot
  be restored to normal operating conditions, the
  process safety system automatically takes the
  next action to prevent a hazardous event from
  occurring.
• Problems of Alarm System
• Nuisance Alarms
• Indicates an abnormal situation when none occurs
  or when process conditions do not change as a
  result of such generated alarms to operators.
  Over time, these warnings drive operators to
  adopt a nonchalant attitude and desensitise them.
  Instrument-generated alarms in normal operating
  conditions are a good illustration.

• Nuisance alarms should be checked and addressed
  as soon as possible nuisance alarm reduction is
  a continual process that should be continued
  until a stable, steady-state operation is
  attained.
• Operator Response
• Operators must have a clear understanding of what
  response is necessary for every alarm in order
  for assets to operate effectively. As a result,
  operators must be well-trained in all types of
  alerts and the actions that must be taken, as
  well as provided with necessary information such
  as Standard Operating Procedures (SOPs).
• Stale Alarms
• Alarms that have been activated for longer than
  24 hours are considered stale. These could be
  alarms that don't require a response or alarms
  that did once require a response but are no
  longer required. These alarms clog up the alarm
  summary and make the operator unresponsive.
• Frequent Alarms
• A sign of impending failure that should prompt
  you to maintain your equipment before it breaks
  down. If the warnings are occurring too
  frequently, immediate care is required. If
  alarms are set wrongly, the settings may need to
  be reevaluated.
• Alarm Flood
• Alarm floods are a spike in the number of alerts
  generated in a short period of time, usually
  caused by an event such as a process disturbance
  that floods the system and overwhelms the
  operator. Floods obscure the operator's capacity
  to respond correctly to crucial or important
  warnings by obscuring the decision-making
  process.
• Alarm floods are determined by the number of
  alarms received in a certain time span divided
  by a threshold. Alarm floods are one of the more
  challenging issues to tackle and reach a
  definitive conclusion on. To resolve such
  challenges, an effective Alarm Management
  Service should offer an accurate timestamp of
  events within the context of the process
  hierarchy.
• This is especially true for control loops that
  are more sophisticated and cascaded. The primary
  goal of alarm rationalisation is to decrease
  superfluous alarms while also providing tools to
  quickly determine the fundamental cause and take
  action in any situation. During the alarm
  rationalisation process, however, it is a good
  idea to avoid and eliminate alarm duplication.
• Disabled/Suppressed/Shelved Alarms

• Preventing the operator from being notified of
  the alert.
• Variable Table/Master Alarm Data
• These are usually tabular (Excel) and list all of
  the potential process alarms, along with their
  potential implications, repercussions and
  suggested Operator replies.
• A competent Alarm Management service system can
  show where the problems are, what the problems
  are caused by and provide the operator with
  enough information to make the best decision
  possible.
• Why is Alarm Management Service important?
• There's a strong urge to raise an alarm for any
  possible departure, even if it doesn't require
  immediate attention. This approach, known as
  alarm flooding, can trigger a large number of
  alarms at the same time in the event of a serious
  disaster. When this happens, operators may be
  unable to identify and respond to critical
  alarms, causing the problem to increase in
  severity.
• Alarm flooding, in the worst-case scenario, can
  result in significant environmental damage,
  productivity loss, injury or even death of plant
  staff. Alarm system administration is critical
  for dealing with alarm flooding and other
  associated concerns.
• An Alarm Management Service or system will
  identify alarm issues and recommend solutions.
  The argument for implementing an Alarm Management
  System can be found in the prevention of a
  single unplanned shutdown.
• An effective management system should include
  capabilities for analysing all of this data,
  from high-level data extraction to event-by-event
  analysis to determine the underlying reason. It
  should make alarm maintenance easier for
  everyone, from simple systems to complicated
  alarm management systems.
• Data that can be customised for many places and
  plants
• Data reporting to determine top alarms, priority
  distribution, alarm rates, and so on, using
  current data infrastructure
• Alignment with the ISA TR 18.2 standard for alarm
  management
• Combine operator logs, notifications, analysis
  data and alarms into a single, searchable log.
• A chronological log of plant occurrences with
  process data correlation
• Full-featured search
• Grouping of alarms

• Fully customizable
• Standard Operating Procedures (SOPs) should be
  integrated into documents.
• Add comments, operator responses, likely causes,
  and so on.
• Document the result of the deviation.
• Suggested remedial action or SOPs
• Integrate with existing maintenance systems
