Some Sobibór survivors were spared the gas chambers because they were transferred to slave-labour camps in the Lublin reservation , upon arriving at Sobibór . These people spent several hours at Sobibór and were transferred almost immediately to slave-labour projects including Majdanek and the '' Alter Flugplatz '' airfield in the city of Lublin , where materials looted from the gassed victims were prepared for shipment to Germany . Other forced labour camps included Krychów , Dorohucza , and Trawniki before the killing spree of '' Aktion Erntefest '' . Estimates for the number of people sent away from Sobibór range up to several thousand , of whom most perished before the end of the Nazi regime . The total number of people in this group include 16 known survivors ( 13 women and 3 men ) from among the 34,313 Jews deported to Sobibór from the Netherlands
