建筑问题:刺激危险

经过格雷戈里·哈维尔(Gregory Havel)

Any response to a construction job site exposes emergency workers to hazards that are not common in finished buildings. Among these hazards are access problems, temporary lighting that would be considered inadequate by the building code in a completed building, temporary storage of materials, liquid and gaseous fuels, housekeeping issues, trip and fall hazards, and impalement hazards.

由于可见性较差,因此刺激危险可能特别危险。最常见的刺激危险是用于加固混凝土的钢棒(钢筋)。

The Occupational Safety and Health Administration (OSHA) in 29 CFR 1926.701(b) requires that the exposed ends be covered with a metal-reinforced cap (photo 1), lumber at least 1½ inches thick, or other protection for workers against injury by cuts or by impalement from falls. In poor lighting or dusty conditions or in the glare of bright sunlight, rebar can blend into the background of concrete and concrete block.

钢筋垂直安装在基础上(照片2),以加强将在其上建造的基础墙。这些钢筋通常从底部通过混凝土砌块墙的芯向上延伸到墙壁顶部的梁,梁或托梁的轴承板。在任何时候,工人都可以暴露于钢筋的切割或刺激危险时,应将末端盖住(如照片中的照片)或其他受到保护。

钢筋还以水平安装在基础上,倒入混凝土墙和“粘结梁”(照片3)中的基础上(照片3)中安装。如果钢筋末端得到适当的保护,绊倒和降落不会引起刺激,但仍然会留下令人讨厌的瘀伤。在照片3中,下键梁中的钢筋正确封闭。在上部粘结梁中,必须在该区域开始额外的工作之前上限钢筋。

尽管钢筋是建筑工地中最常见的刺激危险,但它不是唯一的危险。其他的则包括任何种类的材料或设备,以及在意想不到的地方固定的墙壁上的管道。照片4显示了学校洗手间中管道的供水和废水管道。尽管只有这些管道和安装螺栓中最刚性的螺栓可能会引起刺穿,但如果有人摔倒,其余的仍然会造成瘀伤,擦伤和其他伤害。

OSHA法规规定,“所有突出的加固钢,都可以跌落到其中,应予以保护,以消除刺穿的危害。”[29 CFR 1926.701(b)]

The OSHA regulations also state, “During the course of construction, alteration, or repairs, form or scrap lumber with protruding nails, and all other debris, shall be kept clear from work areas, passageways, and stairs, in and around building or other structures.” [29 CFR 1926.25(a)]

OSHA法规中未明确提及的其他强化危害,例如“一般职责条款” [职业安全和健康法第5(a)(1)条,涵盖了伸出的管道,螺栓,加固线和电缆。,其中指出:“每个雇主应为他的每位雇员提供服务,以及没有造成或可能造成死亡或严重身体伤害的公认危害的工作地点。”根据《联邦法规》的这一部分,OSHA可以并且确实在《联邦法规法典》(CFR)中没有明确提及的建筑工作地点的不安全条件。OSHA还有雇主要求澄清条款和情况的解释信。

每当您被称为在建筑或改建工作现场的事件时,请格外小心。如果您在内部工作,请携带手照明,以确保您可以清楚地看到要去的地方或临时照明是否应该熄灭。还请总承包商或建筑经理陪同护送,以指导我们采取通往该事件的最短路线。
