管庄东方建材批发市场的一户店家表示,如今市场上流通的安全帽主要有三种:最便宜的是塑料安全帽,防护效果;稍好的是ABS树脂材料安全帽,防护效果中等,且价大多在20元以上;的是玻璃钢安全帽,价格也。
很多商家都表示:“很多民工常常会坐在帽子上,将其充当坐凳,安全帽用几天就得换。所以5元的质量虽然最差,但最畅销。”
不过,无论是什么颜色、什么价格,质量都必须要符合统一的国家标准。
正如应急管理部所说的那样,根据最新的国家标准GB2811-2007,质量合格的安全帽在高温、低温及浸水三种情况下,用5Kg钢锤自1m高度落下进行冲击试验,头模所受冲击力的最大值均不应超过4900N(1N=1kg·m/s,即使一千克质量的物体获得1m/s的加速度所需的力);用3KG钢锥自1m高度落下进行试验,钢锥不应与头模接触,且帽壳都不得有碎片脱落。
