Strangulation - The risk of strangulation may arise if the height-adjustable ropes of a swing element create an accessible opening between Ø130 and 230 mm. Climbing ropes, nets, and rope ladders should be secured at both ends so these cannot be looped back on themselves, thereby preventing the creation of an accessible opening between Ø130 and 230 mm. A swing accessory with a long rope should also not be able to be pulled over the start section of the slide or fireman’s pole. Around a child's neck, in combination with a forced sliding motion, this can lead to strangulation.ure.
