Time From Attack to Control 



Table 16 based on records of 986 fires con- 

 firms what one would expect to be the relation 

 between the length of time required to control 

 a fire and the final size of the fire; namely, the 

 longer it takes to bring a fire under control, the 

 larger the final acreage will be. 



longer to go greater distances. But when greater 

 distance from headquarters is coupled with 

 longer time between fire origin and detection, 

 only larger fires yet can be expected. Again re- 

 duction of detection time would far more than 

 pay its way.
