Problem - Locked Doors are a Fire Trap



Large installed base of deadlocked entry and exit doors
  • inward opening solid doors
  • outward opening screen or security doors
Keys needed to open doors, even from the inside
  • Often keys cannot be located in an emergency
Small fires can generate large volumes of smoke
  • visibility reduces rapidly
  • panic sets in
  • asphyxiation occurs quickly
Sticking locks also trap people in smoke filled rooms
