Abstract: A device and method is provided for rescuing a person trapped in engulfing material at an engulfment site. A reduction tool is used to loosen the engulfing material in order to free or facilitate freeing a buried or partially buried victim. The loosened engulfing material is subsequently removed from the engulfment site by vacuum excavation. Shoring equipment may be used to stabilize the excavation site prior to commencement of soil reduction and soil removal procedures. The excavation site may include a sump area to receive loosened engulfing material discharged by the reduction tool from the excavation site. The loosened engulfing material in the sump area may also be removed with vacuum excavation techniques.

Abstract translation: 提供了一种装置和方法，用于拯救被吞没在吞没物质处的物质的人。 使用减少工具来松开吞没物质，以便释放或便于释放埋藏或部分埋藏的受害者。 随后通过真空开挖将松散的吞噬材料从吞没部位取出。 在开始减少土壤和除污程序之前，可以使用支护设备来稳定挖掘点。 挖掘场地可以包括一个集水区，用于接收由减量工具从挖掘位置排出的松散的吞没材料。 贮槽区域中松动的吞噬材料也可以用真空挖掘技术去除。
