Those inside died within 20 minutes; the speed of death depended on how close the inmate was standing to a gas vent, according to the commandant Rudolf Höss, who estimated that about one-third of the victims died immediately.
Cei aflați înauntru mureau în 20 de minute; viteza morții depindea de cât de aproape erau deținuții de gurile de gaz, conform cu declarațiile lui Höss, care a estimat că o treime din victime mureau imediat.
