The LEAA report, after listing the indicators, determined that these indicators have received little or no scientific tests and that “there appears to generally be no published product inside the scientific literature to substantiate their validity” (Boudreau et al. 1977). Despite the deficiency of validity and this warning, the schooling and textbooks within the profession in the course of this time employed these indicators as a means to website link an observation for the speed of the fire and finally to your summary of fire bring about.
