Inadequate emergency equipment also worsened the disaster. Daegu subway trains were not equipped with fire extinguishers, and the stations lacked sprinklers and emergency lighting. Many victims became disoriented in the dark, smoke-filled underground station and died of asphyxiation looking for exits. Emergency ventilation systems also proved inadequate. Over 1,300 fire and emergency personnel responded and the fire itself was extinguished around 1:38 p.m.; however, the toxicity of the smoke prevented them from entering the station for another three and a half hours.
