The guiding principles of alarm design

Define how alarms are created, prioritised, and managed to ensure consistency and operator trust

An Alarm Philosophy is a formal, site-specific document that establishes the foundational principles and rules for managing a facility’s entire process alarm system. It acts as the definitive “rulebook” or constitution, clearly defining what constitutes an alarm, the criteria for its design and prioritisation, the procedures for how operators should respond to alarms, and the roles and responsibilities of all personnel involved.

Adopting Industry Standards

Adopting an industry standard, such as ISA-18.2 or EEMUA 191, as the framework

Defining Key Principles

The team works through each section of the standard to establish site-specific rules

Documentation and Approval

All these decisions are compiled into a document which is then formally reviewed and approved by site management
