Each member of the family should know how to get safely outside by at least two routes. Family members should practice opening their windows to become familiar with their operation. Jammed windows should be identified and repaired. If, during a fire, a window is jammed, it may be broken out with an object and a blanket or towel placed over the frame to cover shards of glass. However, it is much safer to open a window than it is to break the glass out.
The largest loss of life in a residential fire in Phoenix occurred in 1987. A family of four was trapped inside their home and couldn’t get out because security bars were bolted on the windows. If a family feels they need the additional security, "fire safe bars" should be installed or retrofitted. An exit should not require special tools. A key is considered a special tool. The Phoenix Fire Department advises that bars on windows should have a single action quick release device.
