Classification of accidents

Classification of accidents by safety function is the starting point for classification by mitigating system. Because of the factors listed below, classification by system usually produces more accident... 

The three main concepts in this model—safety constraints, hierarchical control structures, and process models—are introduced first in chapter 4. Then the STAMP causality model is described, along with a classification of accident causes implied by the new model. 

Classification of accident causal factors starts by examining each of the basic components of a control loop (see figure 3.2) and determining how their improper operation may contribute to the general types of inadequate control.
