Structural fumigations using sulfuryl fluoride for the extermination of dry-wood termites are conducted by the thousands in California and other warm-weather states. Sulfuryl fluoride is an odorless gas that targets the nervous system and can cause respiratory irritation, pulmonary edema, nausea, vomiting, seizures, and death. Structural voids or compartments such as wall sockets, crawl spaces, cabinets, or cells in air mattresses may create ongoing exposure after a structure has been certified as safe. The authors describe a case of potential sulfuryl fluoride exposure to a family following home fumigation. Despite regulation, sulfuryl fluoride poisonings from structural fumigations continue to occur. This article examines the physical characteristics of sulfuryl fluoride and the regulatory oversight of its application, in an effort to understand how and why these poisonings happen. Increasing aeration times of fumigated structures, overseeing monitoring efficacy, and using technology to capture clearance data could reduce sulfuryl fluoride exposure and illness.
结构熏蒸使用的硫酰氟是一种用于消灭干木白蚁的无味气体，它在加利福尼亚州和其他温暖气候的州被数千次使用。硫酰氟针对神经系统，会导致呼吸刺激、肺水肿、恶心、呕吐、癫痫发作和死亡。壁式插座、爬行空间、橱柜或气垫床中的细胞等结构空隙或隔室在结构被认证为安全后仍可能持续暴露。作者描述了一个家庭在房屋熏蒸后可能接触硫酰氟的案例。尽管有规定，但结构熏蒸引起的硫酰氟中毒仍在继续发生。本文研究了硫酰氟的物理特性及其应用的监管监督，以了解这些中毒事件是如何发生的以及为什么会发生。增加熏蒸结构的通风时间、监督监测效果以及使用技术捕获清除数据，可以减少硫酰氟暴露和疾病。
