Inherently Safer Design (ISD) Principles in Pharma Process Development

Traditionally, chemical plants manage process hazards by adding safety systems (PSVs, interlocks, dump tanks). However, these add-on barriers can fail. Inherently Safer Design (ISD) is a design philosophy that focuses on eliminating or minimizing hazards.

Safety Instrumented Systems (SIS): IEC 61511 for Pharma Engineers

When physical relief devices (like PSVs) cannot handle runaway reactions or toxic releases, process designs rely on Safety Instrumented Systems (SIS). An SIS is an independent system of sensors, logic solvers, and final control elements (valves).
