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.
