At times the guards or Kapos would either deliberately throw the prisoners on the 380 volt electric barbed wire fence, or force them outside the boundaries of the camp and then shoot them on the pretence that they were attempting to escape. Another method of extermination were icy showers – some 3,000 inmates died of hypothermia after having been forced to take an icy cold shower and then left outside in cold weather. A large number of inmates were drowned in barrels of water at Gusen II.
