12月30日, 2021, 马歇尔火灾, a wind-driven wildfire swept through the City of Louisville, 苏必利尔镇和博尔德县的非建制地区, 科罗拉多州, 燃烧6,219英亩, 摧毁近1,100 homes and businesses, and claiming the lives of two people. 马歇尔大火被认为是科罗拉多州历史上最具破坏性的火灾,损失超过20亿美元.

彩宝网平台派出了两个专家小组前往事故现场进行(1)详细的火灾后法医调查,以确定事故的起因和原因, (2)火灾风险评估,评价火灾时建筑物的性能, in addition to identify the breath and range of physical, 环境, 社会和监管脆弱性是造成受影响社区遭受毁灭性损失的原因之一.

彩宝网平台的法医专家, 由博尔德县警长和地方检察官办公室保留, performed witness interviews, on-site observations of the fire scene and fire patterns, researched location and types of ignition sources in the area as well as applicable weather data; and reviewed photography and video of witnesses and/or automated camera 系统. 调查收集并考虑了所有的证据和数据, considering veracity and assembled an incident timeline. 然后,彩宝网平台列出了火灾的可能原因假设,并就火灾的起源和原因提出了意见, and the role played by the electric utility.

For the wildfire 缓解 assessment, 彩宝网平台的专家团队收集了数百份对受损和未受损房屋和商业建筑的实地观察和评估, along with inspections of individual building components, 系统, 和材料. 该小组还对州和当地的急救人员进行了多次采访, 建立官员, 计划部门, 居民, 以及其他机构, 并评估了其他合作伙伴(如NIST和IBHS)开发的大量技术报告.

彩宝网平台的研究发现了被称为“山浪”的大风的危险组合,风速为50至60英里/小时,阵风高达80至115英里/小时,严重破坏易燃和混合自然植被附近的脆弱电源. 除了, 长期的干旱, 高温和当地居民的活动意外地创造了巧合的点火点.

While utility-specific wildfire safety regulations, 指导方针和做法已在加利福尼亚州采用, 哪里有几起与公用事业有关的野火造成了灾难性的损失, 在国家或国际一级还没有更广泛地制定和采用类似的标准和做法.

类似的, for the built environment, wildfire/WUI safety codes and standards, 指导文件和方案已经在国家层面存在.g., IWUI规范,NFPA 1140)和一些州和地方级别(e.g., California Building Code Chapter 7A), 然而,收养, customization and enforcement of these codes and standards, policies and practices are limited.

Beyond codes and standards, 这一事件凸显了需要采取更全面的方法来应对野火,需要在社区采取行动, 社区, 细分, 包裹和建筑规模,包括灾难生命周期:准备, 规划, 响应, 缓解, 和恢复.

除了, 利用结构密度和防火间隔限制城市火灾, performing fine-scale hazard, risk and vulnerability assessments and mapping, coordinating 缓解 for multiple hazards, 并为荒地增加更好的植被管理政策和实践, 公共休憩用地, 绿化带和综合休闲区都显示出该事件有改善的机会.

这项调查和缓解评估的结果现在被用来为改进建筑/消防规范和标准提供信息, 最佳实践, 野火防备的指导文件和其他政策, 预防, 缓解, 恢复和重建. 通过联邦紧急事务管理局(FEMA)的建筑科学灾害支持计划(BSDS), 从事件中得出的意见和建议促成了若干缓解评估小组产品的开发,例如:

  • 提出改进规范和标准、指导文件和程序的建议.
  • 关于代码采用、定制和实施的建议.
  • Detailed fact sheets for homeowners, 建筑商和设计专业人员解决结构硬化, 防御空间, multi-hazard considerations, 细分规划, 细节和接缝, smoke and ash infiltration.
  • 培训 and outreach presentations and workshops.
  • Marshall Fire Technical Report.

彩宝网平台的野火风险缓解小组继续与STARR II合作伙伴合作, FEMA and other federal/state/local governments, 非营利组织, and private sector clients to better understand, 为......准备, respond to and recover from future wildfire threats, particularly at the wildland-urban-interface. This includes providing community wildfire protection plans, utility wildfire 缓解 plans, 社区外展, 为规划人员提供加强野火恢复能力规划和实施的教育和培训, 工程师, 设计师, builders and the public at large.
