About ISO 11161 (Integrated Manufacturing Systems Safety)

This event covers the compliance, engineering, and verification requirements defined by ISO 11161.

EN ISO 11161 addresses safety of integrated manufacturing systems (IMS) — multiple machines linked by material handling under supervisory control — where hazards, zones, and modes span machine boundaries and single-machine conformity is not enough.

What it regulates

System-level risk assessment, division into task zones with local safe conditions, span-of-control of safeguards and e-stops across the line, mode management (local/integrated), and interface responsibilities between suppliers.

Who must comply

Line builders and lead integrators of automated production/logistics systems combining robots, conveyors, and process machines.

Key requirements of ISO 11161

  • IMS definition and the lead-integrator responsibility
  • Task zones: defining where a person works and what must be safe there while the rest runs
  • Safeguard span of control and zone interfacing
  • Modes: automatic, manual, and degraded operation across the system
  • Documentation splitting supplier vs integrator obligations

Key concepts: ISO 11161

Lead integrator
The party assembling machines into the IMS who owns the system-level conformity.
Span of control
Exactly which equipment each safeguard or e-stop affects — made unambiguous to operators.
Task zone
A bounded area with defined safe state allowing intervention while adjacent zones continue producing.

Frequently asked questions: ISO 11161

Each machine is CE marked — is the line compliant?

No. Linking machines under common control creates a new assembly requiring its own risk assessment and conformity (the IMS becomes machinery in its own right); zone interactions, shared safeguards and modes are exactly where 11161 applies.

Can one zone run while a person is in another?

That is the design goal: task zones with verified isolation (fences, monitored standstill, interlocked transfer openings) so production continues safely around the intervention — with rigorous validation of the zone boundaries.
