The Mother Standard: IEC 61508 Part I, Origins, the Safety Lifecycle and the Map of Seven Parts

Deep End Era. Engineering with Sankalp · Oct 28, 2026 · 1h 2m

A furnace burner management system at Al Sahil is forty years old, built from relays, and nobody can buy the spares any more. The replacement will be programmable, and that changes everything about how its safety has to be argued. Safety engineer Tomas Novak and his new graduate, Aisha Rahman, walk the whole IEC 61508 lifecycle from concept to decommissioning, discovering why the standard exists, what a SIL is and is not, how its seven parts fit together, and why "it's certified" is the start of a conversation rather than the end.
