Some demolition accidents happen in full public view, such as the sudden collapse of a 13-story condominium in Miami Beach in 2018.

在那次事故中，大快速滚动的混凝土块在完成所有准备工作之前开始的渐进崩溃推动，遭受拆除承包商雇用的46次遭受塞缪尔·泰隆Landis的爆发和杀死。

大多数致命的拆除事故，如2021年上半年发生的六次发生，暂时发生在公开场景中，并且不会通过电话摄像机录制。但他们也往往涉及安全专家所说的支持事故的过早崩溃或损失，可以通过适当的规划和关怀来防止。

美国职新利18备用业安全与健康管理局的ENR审查2021fatal demolition accident records表明1月开始糟糕。

The first accident occurred on New Year’s Day last year in Lincoln, Neb. Twenty-five-year-oldMason Mack Harris另一名工人被当地的MWE服务公司雇用，也被称为中西部拆迁，这是在青年庇护所的扩建项目进行拆迁工作。这两者试图在第二层上拆下典型的混凝土阳台，在地上约10英尺处。

哈里斯正在使用2-gal。喷雾泵在表面上喷水，以清除他的同事创造的灰尘，他们正在操作砖石锯。

在他们工作的时候，7英尺x 6-ft平板部分在哈里斯的脚下爆炸，在秋天，混凝土落在他的顶部。他死于钝力创伤和破碎的伤口，而他的同事遭遇断腿。

OSHA cited Mwe Services for three serious violations and proposed a fine of $30,000, later reduced to $21,000—and an informal settlement was reached, records show.

该公司没有回复评论请求。

Four days after the Lincoln, Neb., accident, A&W Excavations, based in Chipley, Fla. and recently founded, had several employees working beneath the roof of a commercial building in the area they intended to demolish. According to OSHA records, the crew that was chain-sawing building truss members had been trained in trenching and excavation pipe-laying but not in the task they were performing that day.

As they worked, the roof collapsed, dropping the crew about 15 ft to the floor, killing one member. The others had injuries treated at a hospital.

OSHA cited A&W Excavations for six serious and one willful violations. The initial proposed penalty of $170,000 was cut to $70,000 under an informal settlement.

可能在5月继续存在另一个致命事件。

纽约市里士满建筑公司的一名雇员完成了Brooklyn，N.Y.，建筑物的屋顶部分，沿着暴露的屋顶边散步。在某些时候，屋顶部分分开，工人下降了60英尺到他的死亡。11月，OSHA提出了374,000美元的罚款，以获得严重和故意的违规行为。上个月，公司表示将举行处罚，OSHA记录展。

Miami Beach Accident Aftermath

The 2018 Miami Beach accident, which occurred on July 23, was one of the most unusual accidents captured on video.

电话录制显示兰迪斯，其他人逃离封闭的柯林斯大道，因为致命的混凝土块从坍塌的结构和尘埃云向外滚动。一个混凝土块在腿上撞击兰迪斯，视频显示，第二个块击中他在胸前，向他落后和地面。他在10天后去世了。

An employee of locally based AlliedBean Demolition, Landis had在建筑行业工作most of his life. According to his obituary, he started as a laborer but also worked as an operating engineer, supervisor and operator of his own demolition contractor.

迈阿密海滩官员在短时间内，曾表示，他们拒绝了项目团队的申请，以便将现有建筑带入爆炸性拆迁。作为替代方案，团队计划没有炸药的渐进崩溃，并邀请观众观看它。

联邦安全官员引用了两次严重违规行为的联盟拆迁，并提出了29,900美元的罚款。达成了非正式的结算，公共记录展示。

Landis’ mother, Judith Anne Landis, filed a lawsuit in 2019 in state court in Miami-Dade County against AlliedBean Demolition and numerous other companies involved with the project. The claims in that suit all were settled before trial, said AlliedBean’s attorney.

公司总统凯文·豆证实了该解决方案，并仅说发生了发生的事情是“不幸的事故”。

突然支持的专家

承包商必须遵循详细的拆迁计划，说肯更短, a Baltimore-based safety consultant and expert witness. That plan should include a hazard analysis and a document about how to proceed with the work. The hazard analysis should be used to train the project crew.

“Any professional demolition company will do that," Shorter said, in order to comply with standards for construction and demolition operations published by the American National Standards Institute and the American Society of Safety Professionals.

此外，一位称职人士应不断监控工作，他说，确保一个结构尚未达到崩溃状态。He said a qualified person is needed to do that and for a complex structure, "a structural engineer may be the way to go.”

承包商北美拆除公司之后的一个重要原则是最大限度地利用设备，尽量减少手工劳动力和暴露于危险条件。

另一条规则，基于基于Rech的承包商在其网站上说，在其网站上表示，在招聘石上保持足够的间距。必须保持安全距离“从爆炸或影响，从下降碎片和拆除设备。”

更短的注意是，因为拆迁工作往往涉及劣化的建筑物，有时悲剧很难避免。

“当崩溃发生时，预测并不总是容易的，”他说。“主管工作的一部分应该是为了确保工人根据计划工作[因为]所有所需要的是一名带有火炬切割太多的工人来崩溃。”
