  7. Wetteren: scenario • 5 rail tankers witheachapproximately 60 ton acrylonitril • Extremelyflammable • Extremelytoxic, release of cyanide after intake in human body • Degradationbyfire: release of hydrocyanic acid andnitriousgasses • Classificied as possiblycarcinogenic. • 2 rail tankers witheachapproximately60 ton butadiene • Extremelyflammable • Cancausecancer • 5 empty railwagons • 1 wagon with 2 containers tri-ethylaluminium (TEAL) • Ignitespontaneously on contact with air • Reactsviolentlywith water • Corrosive
