Temporary buildings, installed on site during the construction phase, may not be removed until the commissioning, completion, or beginning of normal operation. Once the hydrocarbons are introduced, these buildings have the potential to be exposed to process hazards (fire, explosion, toxicity, etc.) resulting in injury or fatality of the personnel inside the building. Providing safe location to these portable building is imperative and should be determined based on detailed hazard analysis, building siting study as per API 753. Facility siting study is done to calculate the potential impact of blast overpressure, thermal radiation from jet fires, pool fires, and toxicity hazards and evaluate the safe distance to the temporary buildings. Simultaneous operations is also evaluated in order to optimize temporary building location and further risk management strategies are implemented such as mitigation measures based on the hazard impacts, like, adding gas detectors at the air intake of HVAC to shut down the power supply to the temporary buildings, public announcement system, evacuation drills, and so on. This paper will address the temporary building siting study and associated mitigation measures with the highlight of its application into the risk management, using a large LNG facility as an example.

基于定量研究的 LNG 现场临时建筑物的位置

在施工阶段安装在现场的临时建筑物，在调试、竣工或开始正常运行之前不得拆除。一旦引入碳氢化合物，这些建筑物就有可能暴露于过程危害（火灾、爆炸、毒性等），从而导致建筑物内的人员受伤或死亡。为这些便携式建筑提供安全的位置势在必行，应根据 API 753 的详细危害分析、建筑选址研究来确定。进行设施选址研究以计算爆炸超压、喷射火灾、水池火灾的热辐射、和毒性危害，并评估与临时建筑物的安全距离。还评估了同时操作以优化临时建筑的位置，并实施了进一步的风险管理策略，例如基于危害影响的缓解措施，例如在暖通空调的进气口增加气体探测器以关闭临时建筑的电源、公示系统、疏散演练等。本文将以大型液化天然气设施为例，讨论临时建筑选址研究和相关缓解措施，重点介绍其在风险管理中的应用。
