衣服拉绳害死几十个孩子 给孩子买衣服要注意的安全细节(2)

实验:帽绳拉拽衣领到底有多大力?

帽绳拉拽衣领给脖子带来的拉力到底有多大?清华大学力学实验教学中心的蒋小林老师进行了实验测试。蒋老师使用测力传感器通过串联的方式,一端接在连帽衫的帽绳上,另外一端再接一根绳子并把它卡在滑梯的缝隙中。以此来测量帽绳被拉紧后的拉力大小。

实验结果显示,模拟绳子被突然卡住以后,绳子上受到的力大概是680牛左后,相当于70公斤,是孩子(假人)体重的5-6倍。实验升级,让小朋友在假人身后用力推一把,检测到绳子所受的力为1300牛左右,相当于将近140公斤的力,为孩子体重的10倍左右。

这么大的力瞬间勒到儿童的脖子上,会造成什么后果?北京中医药大学附属东直门医院骨科主任牟明威表示,这个力量对于一个小孩子来讲足可以造成死亡。他解释说,这样大的力当时就可能造成脊髓损伤,脊髓损伤会导致呼吸肌麻痹,而这种损伤往往会持续很长时间,足以造成脑缺氧以至于脑死亡。

法规:儿童上衣不应出现拉绳

美国相关法规规定,2岁到12岁的儿童上衣绝对不能出现拉绳,欧盟、澳大利亚、加拿大也都有类似规定。

中国《童装绳索和拉带安全要求》、《儿童上衣拉带安全规格》和《提高机械安全性的儿童服装设计和生产实施规范》规定,7岁以下幼童服装风帽和颈部不得设计、生产或使用拉绳和索带;7-14岁儿童服装风帽和颈部的拉带不得有自由末端,也就是说不能松动。

支招:给孩子买衣服注意这些安全细节

国家质检总局缺陷产品管理中心发布的童装消费指引,提醒家长给孩子购物衣服时应注意以下细节:

1.不要购买无标识或标识不完整的衣服,3岁以内的孩子最好购买采用FZ/T 81014-2008的婴幼儿服装和FZ/T 73025-2013的婴幼儿针织服装标准生产的产品;

2.尽量不要给14岁以下孩子购买脖子或帽子上有绳带的童装,或把绳带完全取下后再给孩子穿;

3.腰部绳带不要超出童装底边,应将其剪短后给孩子穿,背部有拉带伸出来的童装,以及绳带超出裤脚底边的裤子也都应尽量避免,因为长绳带容易使孩子绊倒或摔倒;

4.尽量选择饰物少,特别是金属饰物少的童装,童装上的亮片、水钻等饰物都可能导致孩子在穿衣服的过程中发生危险,比如误食、划伤、窒息等;

5.尽量不选袖口或裤脚有松紧带的衣物,因为松紧带如果太紧或太硬,会阻碍足部或手部血液循环,产生局部缺血性伤害;

6.尽量不给小男孩买带拉链的裤子,以免造成儿童生殖器被夹住。
