Yesterday,美国化学安全板（CSB）被设定为在2013年4月17日，西部化肥火灾和西部，德克萨斯州的爆炸的最终报告和安全建议表决，这导致了15个死亡，超过260次伤害，群体遭受普遍的伤害。在通过在储存和配送设施的火灾中加热后，在大约30吨肥料级硝酸铵（Fggan）爆炸时，发生了致命的火灾和爆炸。

该团队旨在展示其调查结果和建议以及显示导致事件发生的事件的3D动画。

CSB主席Vanessa Allen Sutherland表示，“这是CSB中有史以来最具破坏性爆炸之一。CSB的报告发现，有限的监管监督，危险性差不良，应急规划不足，以及设施对附近的房屋和其他建筑物的附近都导致了事件的严重程度。拟议的安全建议解决有助于防止未来类似悲剧所需的步骤。“

The CSB determined that FGAN storage falls under a patchwork of U.S. safety standards and guidance – a patchwork that has many large gaps. These gaps include a lack of adequate federal, state or local oversight on FGAN storage and handling and the permitted use of combustible wooden buildings and wooden storage bins.

在联邦一级,无论是环境公关otection Agency (EPA) or the Occupational Safety and Health Administration (OSHA) adequately address FGAN in their existing regulation of highly hazardous chemicals. EPA does not cover FGAN under its Risk Management Program (RMP) rule, and OSHA does not cover FGAN under its Process Safety Management (PSM) standard or clearly identify coverage of FGAN in its Explosives and Blasting Agents Standard.

The CSB recommends to EPA that they cover FGAN under their RMP program and that OSHA cover FGAN under PSM or revise its Explosives and Blasting Agents Standard to clearly identify FGAN hazards– either option would address conditions that likely resulted in the West Fertilizer incident such as the safe storage of FGAN, construction materials, and fire suppression systems. Additionally, existing facilities should be required to phase in replacement of bins constructed of combustible material – such as wood – with noncombustible material.

CSB主管调查员Johnnie Banks表示，“由于其调查结果，CSB呼吁OSHA和EPA呼吁加强其保护公众保护肥料级硝酸铵造成的危害。”

CSB的最终报告发现，全国各地有超过1,300个设施，店内，四十人在德克萨斯州，近一半位于学校，养老院或医院的半英里范围内。八十三个设施位于居住区的四分之一英里。

The CSB is also making recommendations to the International Code Council to develop a chapter for fertilizer grade ammonium nitrate in the International Fire Code. This should include requirements for new and existing facilities storing ammonium nitrate to prevent the conditions that lead to the uncontrollable fire and explosion. CSB also found that lessons learned from previous FGAN incidents were not effectively communicated to emergency responders in other communities where the chemical is stored.

主导调查员Johnniebanks表示，“总的来说，CSB的调查发现，培训和参考资料没有充分地通知紧急响应者对充满火灾引爆的可能性。”

因此，CSB建议职业和志愿者firefighte.德克萨斯州的r关联建立了培训和行为外展对国家的消防员和应急响应组织的最低标准。

主席Vanessa Allen Sutherland表示，“CSB的目标是确保由于缺乏对其社区危险化学品的认识，因此没有其他人被杀死或受伤。如果通过，董事会的建议可以帮助防止德克萨斯州西部的灾害等灾害。“
