In brief: Anyone who assembles or retrofits window and actuator assesses the risks of the finished power-operated window. This checklist helps you not to forget anything. It does not replace standards or legal advice, but covers the typical points.
1. Record the installation situation
- Position of the window: fanlight, façade within reach, roof?
- Who is nearby: employees, children, people in care, the public?
- Opening type, sash dimensions, weight, Stroke.
2. Identify hazards
- Crushing and shearing points at main and secondary closing edges.
- Sash falling if the hardware fails.
- Unexpected start-up due to automation or sensors.
- Wind and rain load with the window open.
3. Define protective measures
- Automation only on windows out of reach.
- Choose force and speed to suit the sash.
- Mount switches so that the window can be seen when operating.
- Edge protection or sensors where windows within reach move automatically.
- safety stay or safety stay against falling.
- Wind monitor and Rain sensor.
4. Document and hand over
- Record the result of the assessment and the measures chosen in writing.
- Declaration of incorporation and file the assembly instructions of the actuators.
- Instruct the operator on operation and inspection obligations, see ASR A1.6.
Background: Power-operated windows from 2027. For questions on choosing actuators, we can help via the Project enquiry.
Frequently asked questions
Who has to carry out the risk assessment?
Whoever assembles window and actuator into a power-operated window or retrofits an actuator – usually the window or metal fabricator or the installer.
Is the declaration of incorporation of the actuator enough?
No. It only applies to the actuator as partly completed machinery. The finished window requires its own assessment.
