国际安全设备协会和美国国家标准学院在7月16日的联合公告中宣布,两组均批准了一个新标准,以建立销售产品的最低设计,性能和标签要求,以防止手动工具(例如手动工具)从高度。它提供了测试此类安全设备的生产样品的准则,以证明合规性。

The long-anticipated "ANSI/ISEA 121-2018, American National Standard for Dropped Object Prevention Solutions" now will be promoted for adoption by safety-equipment manufacturers, product specifiers and end users as the recommended standard of care.

“这是一个自愿共识的标准,但强烈鼓励他们遵循,因为通过ANSI流程制定标准是基于大量测试,并且大量的工程来确保产品能够完成他们制造的产品要做。”领导该项目的ISEA传播总监Lydia Baugh说。

鲍尔说:“我们鼓励最终用户与制造商接触,并要求他们为他们提供符合这些标准的安全产品。这是减少掉落的工具事件的重要一步。”

The Occupational Safety and Health Administration tracks "struck-by-falling-object" incidents. The Bureau of Labor Statistics reported 47,920 injuries and 255 fatalities in the U.S. in 2016 caused by dropped objects, making it the third leading cause of injuries on jobsites, says ISEA. According to BLS data, injuries caused by dropped objects were up by 6.85% and deaths were up approximately 3.24% over the previous year.

Black&Veatch的安全经理Anastasia Urbanik表示,该标准为束缚设备的质量构建提供了基准,“希望将推广新的和创新的产品,并提高工人和公众对物体危害的安全性。”

Urbanik说:“该标准的意义在于,它为其产品提供了最低的设计标准。指定的。”Urbanik补充说,将标准纳入合同文件和书面计划是下一步,但她说,要对消除或减少掉落的对象事件产生更大的影响,需要制定其他标准,以提供有关何时何地的进一步指导要使用束缚设备。

Baugh说,ANSI和ISEA已经开发了许多有关“从头开始”的标准重要性的信息。她说,现在使用它的最佳方法是让雇主将符合标准符合标准的产品的要求纳入其自己的工作地点的“高度工作”政策。

制定标准的努力得到了一个由建筑公司和安全设备制造商等人组成的委员会的支持。Key-Bak产品管理和营销总监Nicholas Voss是一家为绑扎手工工具的设备的公司,已经参与了工作。他说,该标准已经开发了大约八年,但是这项工作是在2014年的一次事件中振奋的,其中一项磁带措施下降了约400英尺,偏转了一件设备,并杀死了58年的加里·安德森(Gary Anderson) -老式卡车司机正在新泽西州泽西市的一个建筑项目上运送大量墙板

Voss说:“对于在高度携带或使用的设备上,标准的定义非常明确,例如具有螺栓和物体的工具或袋子。”

沃斯说,该标准需要在非常具体的条件下按类型和产品进行动态测试,例如2倍长度测试,如果系绳为50英寸,则用100英寸的长度进行测试。掉落,好像是被拿着工具顶部的工人放下的一样;再加上2倍的安全因素负载测试,其中,如果将其定为5磅载荷,则必须通过10磅的负载测试,并且在极端温度下从-31ºF到 +113ºF,在测试前浸泡两个小时后,在湿条件下。

"In the short run there will be an uptick in companies adopting dropped-object prevention, especially companies that have had near misses or had an incident recently," Voss predicts. "Some companies will adopt it as a way to de-risk their operations, after deciding it is better to have tool tethering or instruct their subcontractors to have it than to have an incident. The other half will wait until they are required to do so by law or have an incident."

Baugh says, "rather than relying on duct tape and rope, they actually have products that are following a performance standard they can use to make sure they are getting the right protection for their tools to eliminate hazards from dropped objects," she says.

沃斯说,2014年击中和杀死安德森的1磅磁带措施将产生与15码处45口径手枪射击的子弹相同的影响力。

沃斯说:“很多人都了解弹道的人,一旦听到弹道,灯泡就会消失。”“这不是个人防护设备;您不是个人保护自己,而是保护他人。这可以保护您的同事或好友。”他补充说,许多现代的系tether旨在完全缩回,以解决绳索或线圈设计可能会抓住物体并自行造成危害的抱怨。
