Keeping Up with Technology Revisited: Impact-Resistant Products

经过里克·豪尔赫(Ric Jorge)

“如果您还没有遇到抗影响的产品,那么您就会醒来。”那是我在2004年为佛罗里达出版物撰写的一篇文章中的开幕词,我仍然坚持下去。在过去的七年中,我目睹了这个行业爆炸并以通常用于荒野大火的速度传播。本文旨在提高人们对产品的认识,因为您的地理位置位置很少考虑。这不仅仅是佛罗里达的事情。这是一种全国性的趋势,如果我们没有做出相应的准备,他们对消防员的影响将是致命的。

在佛罗里达州,由于我们接触飓风和龙卷风,这些产品越来越受欢迎,但直到2003年,我才在墨尔本消防学院,我才接触到我见过的第一个撞击玻璃。188博金宝体育1萨拉索塔县(佛罗里达州)消防局的杰里·詹森(Jerry Jensen)在一次演讲中展示了一个。在那里,我还与迈克·哈特利(Mike Hartley)和约翰·埃尔伍德(John Elwood)(萨拉索塔县大火的两者)一起获得了一段视频(2001年创建),并与PGT®窗口一起展示了这些窗户的强度。从那时起,我已经使我的业务尽可能多地了解这些产品。

Impact products of all sorts, not just windows, can be found in residential, commercial, and high-rise buildings across the country. The U.S. government is retrofitting all government buildings (including U.S. embassies overseas) with these products as well as all military buildings/installations. Currently, the Centers for Disease Control and Prevention headquarters in Atlanta is being retrofitted. In Florida, it is part of the Building Code standard 1609, 1626 for new and existing structures that are determined to be in the “wind-borne debris region.” The insurance company enforces compliance, which is reflected in your homeowner rates.

I will use the term “impact” to identify products found in today’s market for wind-loading (pressure) as well as impact (debris) rating. Impact-rated products come in various forms such as windows, doors, garage doors, shutters, roofing material, and even new wall construction.

New wall construction is merely a variation of tilt wall construction used in the residential market, which allows homes to withstand significant wind and impact loads over concrete block structure (CBS) or wood frame. This type of construction has variations throughout the country. Styrene is being employed with rebar and concrete to increase the R* value (a measure of thermal insulation) and water resistance factor. What differentiates this type of construction for firefighters is the degree of difficulty in breeching these walls as opposed to conventional CBS or frame types of construction.

Windows and doors (including garage doors) receiving a state (for example, Florida) mandatory impact rating at a hurricane testing laboratory (HTL) must withstand several types of tests. Testing is broken into categories according to the rating a product must achieve. A hurricane rating is broken into three tests.

1。碰撞测试:通过在窗户上拍摄大或小物体来完成。
2。Rain test:Eight inches of water per hour at 110 to 120 miles per hour.
3。Air leak test:A cyclical pressure test lasting five hours.

为了获得“多狂想减轻”的名称,该产品还必须接受其他测试:

1。Fire:测试是一个小时的消防等级。
2。炸弹:测试是快速的压力构建,其次是碎屑(大小)。
3。飓风:前三个测试(撞击,雨,漏气)。
4。Tornado:测试是用大碎片进行的,很少或没有压力

火灾炸弹式武器(FBH)认证包括上述所有测试,并且可以以9/16英寸的窗户和聚碳膜的形式出现。尽管该玻璃令人印象深刻,但框架更加强大。这些框架的制造方式使它们相互锁定,从而使他们能够在测试中生存。然后,它们每八到12英寸就附着在建筑物上。尝试“清洁窗户”不再使用钩子或哈里根(Halligan)进行,以快速,干净地完成此任务。现代影响窗口比20年前的窗户强10倍,并且涵盖了更广泛的用途。这些产品最重的浓度是在东部沿海地区发现的,但是可以在全国各地找到这些产品,被吹捧为安全产品。

这些产品不仅为消防员造成了违规问题。盒子已经变得更加紧密,这意味着在火灾中将保留热量。我们习惯于看到,使“阅读”更具挑战性时,烟雾不会发出。流道有可能更加定义和危险。现在比以往任何时候都更需要了解,因为我们在这些建筑物中的错误余地远低于传统培训所教给我们的余地。
