不少人喜欢在公园、河堤等地放风筝,但风筝线若管理不当可能对行人及车辆造成严重伤害。
不少人喜欢在公园、河堤等地放风筝,享受放飞乐趣的同时,也需警惕那根不起眼的风筝线。稍不留神,它就可能成为“隐形杀手”。日前,在浙江杭州发生一起相关案例。
根据事发时的行车记录仪画面显示,10月25日下午2点左右,浙江杭州的余女士驾车经过东湖高架时,空中突然出现一根白线。由于事发突然,余女士来不及作出反应,车辆直接撞了上去。
事发后,余女士立刻报警求助。属地交警到场调查后发现,这根悬在空中的白线是一段风筝线。
杭州市公安局临平区分局交管大队城区中队指导员傅渊:到现场以后发现一根风筝线,长约数百米,造成余女士的车顶、雷达、门框、天窗损坏。经过全力排查和视频追溯,找到了涉事的风筝和放风筝的人。经调查以后,该事故属于意外事故,目前事故已经得到了认定和后续处理。
消防实验实测
风筝线“威力”到底有多大?
看似纤细柔软的风筝线,为什么能轻易割伤车体?它的威力到底有多大?总台记者联合杭州市消防救援局开展了一组实验,一起来看。
此次实验选取的是市面上最常见的聚酯纤维风筝线,这类线结实耐磨、不易拉断。
静态切割实验
消防员将风筝线紧绷固定在两根柱子之间,用鸡胸肉模拟人体软组织进行测试,紧绷的风筝线将鸡胸肉切成两块。
动态切割实验
消防员将同规格风筝线以相同拉力紧绷固定在两棵大树之间,在距离风筝线30米以外骑电瓶车出发,以25公里每小时的速度模拟日常骑行状态,依次手持萝卜、青椒、鸡胸肉快速划过风筝线。经测试,三种物品接触风筝线的瞬间,均被紧绷的风筝线直接斩断。
杭州市消防救援局钱江世纪城消防救援站消防员李文奎:在动态实验中,风筝线接触面积极小,在快速移动碰撞的过程中,切割能力会呈几何倍数增长,切得更快更锋利,如果是行人或者骑行者,高速撞上紧绷的风筝线,极易被割伤,若接触到颈部,甚至可能切断血管气管,乃至危及生命。
此外,无论是骑车的消防员还是坐在电瓶车后排的消防员,在车辆行驶过程中,明显感觉到了视觉偏差。
李文奎:我感觉距离线还有很远,但一抬头已经近在眼前了,如果是真实的行车过程中,想要避险已经来不及了。
交管部门提醒:
放风筝时务必远离城市道路和人员密集区域,选择空旷、无通行需求的场地;
骑行、步行经过有放风筝的区域时,请提前减速慢行、仔细观察,谨防意外发生。
