A crushing point occurs where two parts move towards each other when closing – on a window between sash and frame. On a window with an actuator, a hand or finger can be trapped there. There are also shearing points, where parts slide past each other.
Where are the danger points?
At the main closing edge opposite the hinge and at the secondary closing edges at the sides. The greater the force and speed of the actuator, the higher the risk.
How is the danger reduced?
- Actuator on windows out of reach (fanlights).
- Force matched to the sash instead of “as strong as possible”.
- Operation by switch with a view of the window.
- Edge protection or sensors if windows within reach are to move automatically.
The assessment takes place in the Risk assessment.
