About ISO 14118 (Prevention of Unexpected Start-Up)

This hands-on workshop builds applied knowledge and team exercises around the certification requirements of ISO 14118.

EN ISO 14118 specifies measures preventing unexpected machine start-up during human intervention — the foundation of safe maintenance, cleaning, and jam clearing — via energy isolation, dissipation, and start-command control.

What it regulates

Isolation and energy dissipation devices (electrical, pneumatic, hydraulic, gravitational, stored energy), lockout capability, and design measures preventing start commands from reaching actuators during intervention.

Who must comply

Machine designers defining maintenance access; plant operators implementing lockout/tagout consistent with the machine's provisions (OSHA 1910.147 in the US context).

Key requirements of ISO 14118

  • Hierarchy: isolation and dissipation where reasonably practicable for interventions
  • Requirements for disconnectors, valves, and locking means
  • Control-system measures (safe standstill monitoring, key transfer) where full isolation is disproportionate for short frequent tasks
  • Verification of energy states before access

Key concepts: ISO 14118

Energy isolation
Physical separation from all energy sources, lockable in the safe position.
Safe standstill via control system
Monitored standstill (as an SRP/CS function) permitted for frequent short interventions per risk assessment.
Stored energy dissipation
Bleeding accumulators, discharging capacitors, restraining gravity loads before access.
Trapped key systems
Mechanical key-transfer schemes enforcing sequence between isolation and access.

Frequently asked questions: ISO 14118

How does ISO 14118 relate to LOTO regulations?

ISO 14118 governs what the machine must provide (isolation points, lockability, dissipation); operational lockout procedures like OSHA's 1910.147 govern how personnel use them — both must fit together.

Is control-system-based prevention of start-up acceptable instead of lockout?

For frequent, short, low-complexity interventions the risk assessment may justify monitored safety functions (safe standstill, enabling devices) at appropriate PL; for maintenance-type work full isolation with lockout remains the expected measure.
