This creates places where fingers or hands can be trapped. These edges are called <strong>closing edges<\/strong>.<\/p>\n\n\n<h2 class=\"wp-block-heading\">What is what?<\/h2>\n\n\n<ul class=\"wp-block-list\"><li><strong>Main closing edge:<\/strong> the edge of the sash that runs towards the frame when closing, usually the upper edge on a tilt window. This is where the risk of crushing is greatest.<\/li><li><strong>Secondary closing edges:<\/strong> the side edges of the sash. Crushing and shearing points arise between them and the frame or reveal.<\/li><\/ul>\n\n\n<h2 class=\"wp-block-heading\">When must protection be provided?<\/h2>\n\n\n<p class=\"wp-block-paragraph\">The decisive factor is above all the installation height. If the crushing and shearing points are up to 2.50 m above the floor or a standing surface, they are within reach and must be secured. Windows whose sashes are entirely higher are considered less hazardous. Whoever assembles actuator and window must carry out a risk assessment in accordance with the Machinery Directive.<\/p>\n\n\n<h2 class=\"wp-block-heading\">Typical protective measures<\/h2>\n\n\n<ul class=\"wp-block-list\"><li><strong>Hold-to-run control:<\/strong> the window only moves as long as the button is pressed<\/li><li><strong>Low closing force and slow movement<\/strong> in the last stretch before closing<\/li><li><strong>Safety edges or light barriers:<\/strong> stop the sash on contact<\/li><li><strong>Covers<\/strong> on the secondary closing edges<\/li><\/ul>\n\n\n<p class=\"wp-block-paragraph\">This page gives an overview and does not replace a risk assessment.
