Schnellanalyse bei Chemieunfaellen und Braenden mit mobilem GC-MS-System Abschlussbericht

A mobile GC-MS-system for hazardous organics in fires or chemical accidents, which can be used by fire-fighters, was developed in cooperation with Bruker-Franzen Analytik Bremen. In case of fires or chemical accidents a rapid identification and correct assessment of hazard for the population and the environment is essential on-site. The objectives of this project are: 1. helicopter based emergency response with GC-MS, 2. simple procedures for sampling and 3. rapid and automatic analysis in 5 min. Since 1992 twenty German fire-brigades take part in a field study. Sampling equipment for air, water and soil is used. At 150 real incidents over 500 samples have been taken and analysed with rapid analyse methods by mobile GC-MS. The results are integrated in a database for further evaluation. Special MS-databases have been composed which operate hierarchical for fast and automatic identification with high reliability. Three analytical categories have been found: category I: chemical accident - single substance, category II: chemical accident - several substances, category III: fire - complex mixtures. The mobile GC-MS-system inclusive data system, mobile modem and power supply can be carried by 2-4 persons on a stretcher and will be transported by helicopters to the location of action. The results of analysis can be transmitted to center of expertise by wireless remote data transmission in a few minutes.
