    • Four times the maximum flame height (20 foott-flame height x 4 = 80 foot-radius from firefighters)
    • Size based on amount of resources and equipment
  • Discuss heat impact factors that will affect the guidelines for distance separation.
    • Convection heat from wind and terrain features
    • Location relative to fire spread
    • Reburn potential of fuel in safety zone
  • Discuss how firefighters have a right to know the location of their escape routes and safety zones at all times.
  • Discuss how firefighters have a right to ask for clarification when faced with unclear instructions or fear of the unknown.
  • Describe a basic procedure for identification of effective escape routes and safety zones.
