text: There is a lack of scientific research regarding EWSS. Other issues that may affect the effectiveness of an EWSS:
  * Sprinkler performance in high wind conditions typical in a bushfire
  * Home design
  ** High vulnerability areas.  e.g. decking
  ** Garden beds near walls
  ** Window sills
  ** Large windows (heat radiation)
  ** Internal furnishings (e.g. curtains)
  * Home location
  ** Slope
  ** Surrounding vegetation
  * If defended by occupiers
  * Preparation (if prepared for defense)
  * If intended for remote (unattended) defense
  * Available water supply
  * Ember attack
  * Fire front (radiant heat)
  * Adjacent building or vegetation fire
