What does it mean for power-operated windows?
- Windows and fanlights must be able to be opened, closed and adjusted safely – high fanlights, for example, by actuator.
- Crushing and shearing points must be avoided or protected, see crushing point.
- Power-operated windows are inspected regularly, as a rule annually, by a competent person.
