管莊東方建材批發(fā)市場的一戶店家表示,如今市場上流通的安全帽主要有三種:最便宜的是塑料安全帽,防護效果；稍好的是ABS樹脂材料安全帽,防護效果中等,且價大多在20元以上；的是玻璃鋼安全帽,價格也。
很多商家都表示:“很多民工常常會坐在帽子上,將其充當坐凳,安全帽用幾天就得換。所以5元的質(zhì)量雖然最差,但最暢銷?！?/span>
不過，無論是什么顏色、什么價格，質(zhì)量都必須要符合統(tǒng)一的國家標準。
正如應急管理部所說的那樣，根據(jù)最新的國家標準GB2811-2007，質(zhì)量合格的安全帽在高溫、低溫及浸水三種情況下，用5Kg鋼錘自1m高度落下進行沖擊試驗，頭模所受沖擊力的最大值均不應超過4900N（1N=1kg·m/s，即使一千克質(zhì)量的物體獲得1m/s的加速度所需的力）；用3KG鋼錐自1m高度落下進行試驗，鋼錐不應與頭模接觸，且帽殼都不得有碎片脫落。
