混凝土倾斜建筑:您在外面看到的不是您内部的东西

What you see on the outside may not be what's on the inside
What you see on the outside may not be what's on the inside

相片by author except where noted

In Anytown, U.S.A., smaller buildings may be overlooked as not being a major threat to firefighters. Often, however what you see on the outside as your fire unit drives by is not what you get on the inside.

这些小型结构可以具有消防灾难的所有成分。也许建筑物的标志引起了您的注意,但是无论出于何种原因,停止,下车并进行侦察调查。您会对内容感到惊讶,并感觉到这座建筑物在大火期间的反应。带消防公司Know Before You Go (KbyG) mentalityapproach at this particular address will provide building intelligence on the fireground when it is critically needed.

Woodcraft and machinery building

Stop and Get Off the Rig!

Figure 1 shows the Woodcraft & Machinery building, a向上倾斜Type-1 construction structure. Is this a single-floor occupancy like a big box store layout? These tilt-up facade slabs can range up to 40 feet (figure 2) and may have up to three floor levels within these walls.

外部侦察

Perform an exterior fire company recon to gather response ebuilding intelligence on Sides B, C, and D. They will reveal secondary access points, property conditions (figures 3 and 4) with razor wire fences and cargo containers, prohibiting ease access to the rear from exposure (Side B) property. Side C has open spaces from the exposure properties that may be potential ladder truck positions taken off the Overlook St.-wide business driveways.

拖车加载码头和Hazmat标语牌

A closer look at Side D reveals two unique items for firefighters to investigate further as to the reason for a large secondary overhead door (figure 5) and the tractor-trailer POISON placard that is parked in the loading dock with no cab attached (figure 6). Is this a more permanent storage container for lack of interior space?

建筑足迹地图(BFM)数据的收集还将为Fireground初始建筑物尺寸,曝光和其他接入点提供EBUILDINCENT Intelligence Card(EBIC)信息。请参阅下面的建筑物和周围属性图。

即使在部署了无人机(无人机),该固定的BFM显示器在移动数据终端车辆或远程终端上也可以为事件指挥官(IC)提供持续的战斗计划情报。当在这些情况下看不见“天空中的眼睛”时,稳定的火场快照可能是沉重的烟雾条件下的资产。

A rooftop recon survey off an aerial platform apparatus will reinforce what may be seen from Google Map or further highlight any changes that have taken place since this aerial view was taken. This view (figure 7) uncovers that there are five HVAC units, multiple solar (PV) panels, and 22 rooftop skylights.

内部侦察:一楼

在这座倾斜的建筑物内,可能会引起有关消防员安全和预防措施的更多危险信号。尽管一楼是典型的商业展示区(图8),但消防员也应在天花板区域训练他们的眼睛。该高空区域强调了屋顶的裸露的轻巧工程导向板板(OSB)afters,天窗,悬挂式HVAC管道工作和第二个毛素水平。

材料存储和重型机械

内部侦察:二楼/夹层

Once on the second floor/mezzanine level, the Side D overhead door could be rationalized by the presence of large quantities of combustible wood materials (figure 9) and heavy machinery throughout the floor area (figure 10). But to get to this level, firefighters would need to advance hoselines up an OPEN OSB-constructed stairwell, which should raise some talking points for the recon team.

没有让您的线消防队执行侦察调查来收集建筑情报,就像根据有关敌人的猜测准备战斗计划。

Having witnessed concerns with the first-floor interior roof/ceiling, these firefighter safety and precaution issues should be addressed now rather when undertaking initial operations (such as when a fire occurs on the second-floor mezzanine level) or after a hard lesson learned. Develop hoseline tactics to quickly locate the staircase from the front door for an attack. This first-floor floor decision-based knowledge coupled with the mezzanine level heavy dead load floor factor will give the IC a better potential understanding of collapse time so he or she can consider alternating attack strategies or switching a defensive attack mode.

几年前,一个大型的倾斜储物仓库,其中包含纸记录着火(图10-10b)。该建筑物在天花板水平上有一个洒水系统,并激活了。火灾是一个具有多个设定点的纵火,超出了当时设计的消防系统的容量。尽管仓库足迹尺寸约为115,000平方英尺,但它具有三层时装秀和储物架系统。该层系统在一个屋顶下,将文档设备的容量提高到345,000平方英尺,其中超过200,000个碳板箱。

Figures-11 to 11B display the various stages of tilt-up exterior wall collapses while Fig.11C shows no exterior façade walls standing. It does however highlight the three-tier paper storage catwalk system along with the mangled storage shelving system.

Having conducted a fire unit recon survey at the smaller Wood Craft & Machinery building will forewarn firefighters about the tilt-up construction uncertainties and provide much the needed battle plan intelligence for various types of construction and occupancy challenges.

KBYG心态解决方案

以下是在木制工艺和机械大楼中要考虑的其他建筑情报点:屋顶r和地板托梁结构成员;地板1和2上的潜在危险威胁;发动机操作的特殊操作;梯子行动;以及Hazmat单元和EMS的注意事项(图12)。

在收集Fireground风险分析eBIC数据时,没有神奇的时间元素。该部门应让消防公司从其响应区内的目标建筑开始。这可能需要进行几次现场访问,但是当一家消防公司进行内部演练时,他们会感谢这种侦察工具将成为道路上的资产。

So where does a fire department archive these specific building fireground threats to safeguard firefighters and occupants, and how does this critical eBIC data become readily available to first-due units and as the incident is unfolding? By adopting a SMART Firefighter KbyG mentality, fire companies can safeguard their own risk by gathering critical building data associated with a specific building.
