IEC 61511 Functional Safety Lifecycle Management System and Pilot Implementation

Posted on 08 Jan 2026

Equinox Automation helped an operator of safety-critical gas infrastructure move from isolated functional safety activities to a single, IEC 61511-aligned lifecycle management system for Safety Instrumented Systems (SIS). The system was validated through a controlled pilot on existing SIFs, establishing consistent LOPA, SIL determination, SIL verification, and SRS practices that can be applied across projects and operating assets. [...]

Fire and Gas Mapping: Why Most Systems Fail Before They’re Even Designed

Posted on 06 Jan 2026

Most fire and gas systems do not fail because of poor hardware or bad engineering. They fail because the project started with the wrong question. In many projects, fire and gas detection is treated as a necessary compliance item — something to be added late, designed conservatively, and justified against minimum standards. The discussion quickly [...]
