UNEXPECTED START-UP
EN ISO 14118 prevention of unexpected machine start-up
A focused guide for machines where people enter or reach into danger zones for cleaning, clearing, set-up, inspection, adjustment or maintenance.
FROM STANDARD TO SCOPE
Four conversations before the design is frozen
Use EN ISO 14118:2018 to make safe intervention part of the machine design rather than a procedural afterthought. The exact solution still depends on the machine risk assessment, applicable EU framework, current standards and any relevant C-type machinery standard.
Identify every energy source
Consider electrical, hydraulic, pneumatic, gravity, stored mechanical energy and external influences.
Define the safe state
Specify how hazardous functions are stopped, isolated, dissipated or otherwise prevented from starting.
Make status reliable
The person intervening needs a dependable basis for knowing that hazardous start-up cannot occur.
WHY IT MATTERS
A locked gate is not the same thing as controlled energy
Perimeter guards manage access. Safe intervention also depends on what happens to hazardous energy when somebody crosses the boundary and begins work.
EU STATUS + DESIGN CONTEXT
Use the standard inside the complete conformity strategy
Harmonised standards are generally voluntary. Where an exact reference is published in the Official Journal, it can support presumption of conformity only for the essential requirements it covers. It does not replace the complete risk assessment, technical file, conformity procedure or machine-specific requirements.
Directive period
The current consolidated citation decision supports Machinery Directive 2006/42/EC. Check the precise reference, restrictions and transition dates.
Regulation transition
Regulation (EU) 2023/1230 applies generally from 20 January 2027. Do not assume a Directive-era citation automatically answers the future Regulation position.
C-type standards
A machine-specific C-type standard may provide more specific solutions or requirements for a particular machinery category.
Edition and Official Journal note
The current consolidated EU decision lists EN ISO 14118:2018, adopting ISO 14118:2017, for the Machinery Directive. Verify the live project position. Check the current consolidated EU decision and Regulation (EU) 2023/1230 at the point of use.
COMMON QUESTIONS
EN ISO 14118:2018 FAQs
Is unexpected start-up prevention the same as emergency stop?
No. Emergency stop is a complementary protective function for emergencies; it should not be treated as energy isolation or a complete safe-intervention method.
Does this replace site lockout procedures?
No. Designed-in measures and workplace isolation procedures need to support each other.
Is EN ISO 14118:2018 in the current EU list?
It is listed in the current consolidated harmonised-standards decision for the Machinery Directive. Confirm the applicable EU framework and current citation before use.
