About this event

A live 30-minute expert session on Inherently Safe Design Measures (Clause 6.2) — A Worked Catalogue (ISO 12100 — Machinery Risk Assessment). What We'll Cover: What inherently safe design is and why Clause 6.2 must be exhausted before safeguarding or information for use Step-by-step application: geometry, force/energy limitation, material choice, speed reduction, mechanical stability, automation of hazardous tasks How each design decision maps to a hazard in the ISO 12100 record and the risk reduction it claims Common mistakes: jumping straight to guards and interlocks, claiming inherent safety for measures that are really safeguarding, no evidence of alternatives considered The design rationale trail — options considered, measure chosen, residual risk after — that assessors look for in st

About Functional Safety Foundations

This online session delivers expert-led instruction on the regulatory landscape and implementation approach for Functional Safety Foundations.

The cross-sector fundamentals underlying every functional safety standard: risk as severity × likelihood, the safety function concept, integrity levels, the safety lifecycle, and the split between random and systematic failures.

What it regulates

Shared vocabulary and reasoning: hazard → risk → risk reduction allocation → safety requirement → verified implementation → maintained integrity in operation.

Who must comply

Everyone entering the field — the conceptual base of the entire catalog.

Key requirements of Functional Safety Foundations

  • Hazard and risk fundamentals
  • Safety function anatomy: sensor-logic-actuator with defined safe state
  • Integrity ladders (SIL/PL/ASIL/DAL) as risk-reduction currencies
  • Random vs systematic failure treatment
  • Lifecycle and management of functional safety incl. competence

Key concepts: Functional Safety Foundations

Random vs systematic
Hardware wear-out/chance failures quantified statistically versus design/process errors controlled by rigor.
Risk reduction allocation
Distributing required risk reduction among mechanical design, safeguards, control functions and procedures.
Safe state
The defined condition a function drives the equipment to on demand or fault.
Functional safety management
Planning, competence, documentation and assessment wrapped around technical work.

Frequently asked questions: Functional Safety Foundations

Why can't testing alone prove safety?

Rare-event targets (like 1e-7/h) are unverifiable by test duration, and systematic errors evade random testing — hence the standards' dual machinery of quantified hardware analysis plus process rigor and independent assessment.
