Abstract

In this paper, we describe an autopsy case in which death was due to accidental carbon monoxide poisoning occurring in a stationary vehicle idling in an open space. To investigate the source of the fatal fumes, the death scene situation was reconstructed using the vehicle. Exhaust gases were found to invade the interior through the floor from a defective exhaust system. CO gas was detected while idling and the level in the cabin gradually rose to 1.5% over a 2-h period. Since the 8-year-old motor vehicle seemed to have been defective for some months, it was concluded that stationary idling overnight caused an accumulation of toxic gases in the interior.

摘要

在本文中，我们描述了一例尸检案例，死亡原因是在露天空间中一辆静止且发动机空转的车辆内意外发生的一氧化碳中毒。为调查致命烟雾的来源，利用该车辆重建了死亡现场情况。发现废气通过有缺陷的排气系统从地板侵入车内。在发动机空转时检测到了一氧化碳气体，并且在两小时内车厢内的一氧化碳水平逐渐升至1.5%。由于这辆使用了8年的机动车似乎已经出现故障数月，得出的结论是夜间静止空转导致车内有毒气体积聚。
