Alarm Management

Improve the performance of your operators through effective Alarm Management.


Having effective operators in a process plant is critical to maximizing production efficiency, product quality, and plant reliability. 

During a single shift , operators make numerous decisions that affect plant profitability. These include actions to avoid unplanned upsets
or to mitigate events that could lead to plant outages. A well-designed and highly-functional alarm system can add to the operator’s decision-making ability.

An effective alarm management program can deliverable quantifiable business benefits in the following areas:

  • Reduction in unplanned downtime (lost production)
  • Increased operator productivity
  • Reduction in avoidable maintenance of process equipment
  • Production optimization / debottlenecking / increased throughput
  • Capital savings for SIL requirement reductions (improved safety)
  • Reduced environmental / regulatory incidents
  • Energy savings 

What Makes an Effective Alarm Management Program?

We at exida will work with you to craft a program that is tailored to your requirements, complies with industry stand-ards and guidelines on alarm management (e.g., EEMUA 191, ISA-18.2), improves operational performance, and is sustainable over the long term.

It typically consists of the following steps:

  1. Benchmark Alarm System Performance
  2. Development of an Alarm Philosophy Document
  3. Alarm Rationalization
  4. Advanced Alarm Design (e.g., dynamic alarming)
  5. Implementation of Rationalization results and creation of Alarm Response Procedures
  6. Alarm System Performance Monitoring & Assessment
  7. Auditing Alarm System Practices and Procedures

The exida alarm management program helps you to “deliver the right alarm at the right time to the right operator so that he/she can take the right corrective action to achieve the right result.”




Establish and document the standards for how your site or company will do alarm management (prioritization, HMI design, testing, training, alarm suppression, management of change, establish performance benchmarks).

Alarm Philosophy

Alarm Philosophy

An alarm philosophy document (APD) is the cornerstone for development and sustainability of an effective alarm management program. It establishes the guidelines for how to address all aspects of alarm management

Alarm Rationalization

Alarm Rationalization

Alarm rationalization (aka documentation and rationalization) is the process of reviewing and justifying alarms to ensure that they meet the criteria for being an alarm as defined in an alarm philosophy document.

ALM 101 - Introduction to Alarm Management Practices & Principles

Operator response to alarms is a critical layer of protection to prevent a plant upset from escalating to an incident. Poor alarm management has been cited as a contributor to numerous industry incidents. Application of alarm management best practices can help increase operator productivity leading to optimized production and less unplanned downtime. The course will show how the ISA-18.2-2009 standard “Management of Alarm Systems for the Process Industries”, and the alarm management lifecycle defined in it, can be used to address common alarm management issues (e.g., nuisance alarms, alarm floods) and to create an effective, sustainable alarm management program that delivers quantifiable benefits.

ALM 241 - Alarm Rationalization with SILAlarm

Attendees will learn how to conduct alarm rationalization of greenfield (new) or brownfield (existing) applications in order to optimize performance of their alarm systems. The class immerses participants in discussion and hands on exercises which have been designed to demonstrate the best practices and requirements for rationalization as taken from the ISA-18.2 alarm management standard and EEMUA 191 guideline. The class focuses on how rationalization can lead to improved operator performance by eliminating / preventing common alarm problems such as nuisance / chattering / stale alarms, incorrect priority, alarm overload, and alarm floods. It also includes a discussion on tips and tricks for creating an alarm philosophy document, such as how to effectively define the “rules” for rationalization. Exercises will use exida’s SILAlarm rationalization tool.

Applying ISA-18.2 Alarm Management Best Practices to Your DeltaV System

This course will show how to implement alarm management best practices in your DeltaV system through the use of tools such as Alarm Help, DeltaV Analyze, DeltaV Mosaic, Alarm Shelving, Conditional alarming, System Alarm Management, XL Reporter, and SILAlarm. It will also discuss how to make your DeltaV system comply with the ISA-18.2-2016 standard “Management of Alarm Systems for the Process Industries” by following the alarm management lifecycle. Attendees will gain an appreciation for the alarm management capabilities available in DeltaV so that they can determine how to best apply them to their operations. The course prepares participants to support an alarm management program for a DeltaV system including tasks such as creating an alarm philosophy document, performing alarm rationalization, analyzing alarm system performance, alarm system maintenance, and resolution of alarm management issues.
