Time and Motion Study

tornado warning A very important tool in determining the appropriate location for an emergency shelter for a home is a “Motion and Time Study”. It is important to determine the time it will take for each family member to reach the safe room from living and sleeping quarters. Tornadoes usually strike with little advanced warning. Most tornado survivors say that they had less than one minute to seek shelter when they found that they were about to be hit by the tornado. Bear in mind that movement may have to be done in darkness and outside under very hazardous conditions.
