This Grant for Rapid Response Research (RAPID) provides funding to study the San Bruno explosion and fire. On September 9, 2010, in San Bruno, California, a suburb of San Francisco, a 30-inch steel natural gas pipeline exploded in flames, igniting a fire that ultimately killed seven residents and damaged or destroyed dozens of houses. An interdisciplinary field team will provide a holistic account of the event across the engineering and social sciences by gathering data on pre-event building, topography, and weather conditions; the rate and modes of fire spread and suppression; and elements of multiorganizational coordination and decisionmaking. The aims of the project are to: (a) improve understanding of how urban fires spread and are suppressed, (b) support development and validation of next-generation urban fire simulation models, and (c) advance theories of resilience. Scholars are now at work on the next generation of fire spread modeling, employing physics-based approaches that encompass many more variables and that explicitly consider variability in building composition, contents, and urban design. As the next generation of models, however, these have lacked opportunities for validation in actual fire scenarios. Thus analysis of the San Bruno fire will appreciably advance knowledge by improving understanding of urban fire spread and suppression, and by permitting validation and refinement of existing models. Management structures such as the Incident Command System (ICS) depend on information flow amongst organizations that are familiar with its use, in situations with recognized procedures. By studying coordination where system familiarity was present, but information was sketchy and ambiguous and procedures improvised, the study will refine our knowledge of the relative strengths of command structures as tools for interorganization decisionmaking. By explicitly considering the interaction of infrastructure capacities and management systems, the project recasts critical infrastructure to include human operators and their deliberate decisionmaking and interventions.The research team anticipates a number of broader impacts. These include the development and dissemination of improved fire-spread models for conflagrations in residential neighborhoods. These models, once validated, can inform the knowledge base of fire protection engineers and urban planners in their design of structures and spaces, as well as firefighters who may be confronted with such situations following earthquakes, landslips, or terrorist activity. Ground-level decisionmaking and coordination approaches will be bolstered by findings on the multiorganizational coordination of the event. The PIs teach numerous engineering and emergency management courses which will ensure that findings reach the user community both directly and through publications and presentations at relevant conferences and symposia. In addition, graduate students will develop skill in post-disaster fieldwork, to include engineering and social-science data gathering, analysis, and theory development. On a larger scale, recent sizable infrastructure failures, such as the collapse of the I35 bridge in Minneapolis, have highlighted the age and condition of US infrastructure. Information developed through this study may inform policymaking regarding burgeoning vulnerabilities in vital systems.

快速反应研究基金（RAPID）为研究圣布鲁诺爆炸和火灾提供资金。2010年9月9日，在弗朗西斯科郊区的加州圣布鲁诺，一条30英寸长的钢制天然气管道在火焰中爆炸，点燃大火，最终造成7名居民死亡，数十栋房屋受损或被毁。一个跨学科的现场团队将通过收集有关活动前建筑，地形和天气条件的数据，提供整个工程和社会科学活动的整体说明;火灾蔓延和抑制的速度和模式;以及多组织协调和决策的要素。该项目的目的是：（a）增进对城市火灾如何蔓延和如何被扑灭的了解，（B）支持开发和验证下一代城市火灾模拟模型，以及（c）推进复原力理论。学者们现在正在研究下一代火灾蔓延建模，采用基于物理的方法，包括更多的变量，并明确考虑建筑组成，内容和城市设计的变化。然而，作为下一代模型，这些模型缺乏在实际火灾场景中验证的机会。因此，分析圣布鲁诺火灾将大大提高知识，提高城市火灾蔓延和抑制的理解，并允许验证和完善现有的模型。诸如事故指挥系统（ICS）等管理结构依赖于在具有公认程序的情况下熟悉其使用的组织之间的信息流动。通过研究协调系统熟悉，但信息是粗略的，模糊的和程序即兴，这项研究将完善我们的知识的相对优势的指挥结构作为工具，组织间的决策。通过明确考虑基础设施能力和管理系统的相互作用，该项目重新塑造了关键基础设施，以包括人类操作员及其深思熟虑的决策和干预。其中包括开发和传播改进的住宅区火灾蔓延模型。这些模型一旦得到验证，就可以为消防工程师和城市规划师在设计结构和空间时提供知识基础，以及在地震、山体滑坡或恐怖活动后可能面临此类情况的消防员提供信息。实地一级的决策和协调办法将得到关于该活动的多组织协调的调查结果的支持。PI教授许多工程和应急管理课程，这将确保调查结果直接或通过相关会议和研讨会上的出版物和演讲到达用户社区。此外，研究生将培养灾后实地工作的技能，包括工程和社会科学数据收集，分析和理论发展。在更大范围内，最近大规模的基础设施故障，例如明尼阿波利斯I35大桥的倒塌，凸显了美国基础设施的老化和状况。通过这项研究获得的信息可以为决策提供关于重要系统中迅速增长的脆弱性的信息。
