Alarm Management

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, including:

  • Identification and classification of alarms
  • Justification of alarms to confirm or establish that they are required
  • Prioritization of alarms
  • Specification of alarm conditions and settings
  • Design of alarms
  • Implementation and testing of alarms prior to service
  • Commissioning of alarms and alarm changes
  • Training in the use, maintenance, testing & modification of alarms
  • Operation and use of alarms during normal and abnormal conditions
  • Maintenance and testing of alarms during service
  • Management of change for alarm systems
  • Performance monitoring and assessment of alarm system performance

An approved alarm philosophy document must be in place before beginning alarm rationalization.

Alarm Philosophy Document Template

exida’s alarm philosophy template has been developed based on industry standards, best practices and company philosophy documents from industry leaders. In particular it leverages the information included in the draft versions of the ISA-18.2 series of technical reports (e.g., TR 1 - Alarm Philosophy). The philosophy template has been structured to make it easy to comply with (and to demonstrate compliance with) the ISA-18.2 standard.
