在1997年，一个13岁的女孩和她的家人停下来观看澳大利亚一家废弃医院的爆炸性拆除。她被飞行的碎片杀死。“几乎在一夜之间，全世界的爆炸不再被积极晋升为观众事件，”新泽西州兰科卡斯·伍兹（Rancocas Woods）顾问Protec Document Services的运营经理Brent L. Blanchard在他的拆除技术历史上写道。
Now there is a sad new chapter. California officials are investigating what went wrong during the Aug. 3 implosion of a Pacific Gas & Electric Co.-owned power- plant in Bakersfield that propelled shrapnel more than 1,000 ft toward a large crowd of spectators, injuring several and partially severing one man's leg.
据当地媒体称，在动力装置现场为观众建立了一个安全区。
In a statement, lead demolition contractor Cleveland Wrecking Co. called it "a terrible accident" and pledged to cooperate with authorities conducting a full investigation. Last year, Cleveland Wrecking was cited by Cal-OSHA after a worker on the same project was killed when the aerial lift he was working on was struck by a collapsing beam.
一名分包商，加利福尼亚州林肯市Alpha炸药的官员无法置评。另一位分包商Demtech LLC拒绝评论，以进行调查。
In a statement, PG&E said it "will work closely with all investigating agencies and the third-party contractors who managed and carried out the demolition" to identify the cause.
Explosive demolition has been thought of as a way to limit hazards to demolition workers, and, over the decades, the blasts have been embraced by audiences. As the media continued to publicize these projects, wrote Blanchard, blasters have continued to struggle with crowd control and related issues, including, in the 1990s, a turn that brought a noticeable shift toward "promotional responsibility," resulting in the safe completion of thousands of recent projects.
匹兹堡大学的传播教授布伦顿·马林（Brenton Malin）表示，有关建筑物倒塌的新闻对媒体来说是低调的水果。
马林说：“像建筑物这样的观众爆炸，这对媒体来说是个好消息，因为它是安全的新闻。您可以掩盖它而不会引起争议。”
承包商和顾问说，爆破器不会渴望现场观众。受控拆除公司总裁马克·路易兹（Mark Loizeaux）表示，他的公司从未邀请公众观看内爆。“我们认为这不是一项观众运动。监管法规禁止在可能存在飞行碎片的地区的员工或其他人。”
Only a handful of companies perform the work, and, although employees have been hurt, the accidents have been few. Keeping spectators away may become a new priority again. Blanchard says he has never seen a blast team actively promote people coming any closer to the blast than watching it on the television news. n
