The gas van was an
extermination method devised by the
Nazis to kill their victims during
World War II.It was a vehicle with an air-tight compartment for victims into which exhaust fumes were transmitted while the engine was running. As a result the victims were gassed with
carbon monoxide, resulting in death by the combined effects of carbon monoxide poisoning and suffocation.Gas vans were used, particularly at
Chełmno extermination camp, until
gas chambers were developed as a more efficient method for killing large numbers of people. The gas vans are extensively discussed in some of the interviews in
Claude Lanzmann's film,
Shoah.
