This study is grounded on the theories of accident causation, particularly the human factor model (ferrell, 1997). according to this model, accidents are caused by an individual's fault due to. The document discusses accident causation theory and prevention. it defines accidents and their causes, which can include unsafe acts by workers or unsafe conditions. it summarizes heinrich's domino theory that unsafe acts and conditions directly lead to accidents and injuries. preventing accidents requires identifying and correcting the root causes of unsafe acts and conditions through.
Accident prevention is the most basic of all safety management paradigms. if safety management is effective, then there should be an absence of accidents. conversely, if accidents are occurring then effective safety management must be absent. therefore, understanding how accidents occur is fundamental to establishing interventions to prevent. Perhaps the most popular systems theory on accident causation is james reason’s swiss cheese model, originally proposed in 1990. according to this theory, every step in a process has the potential for failure. 10 each layer of defense is represented by a slice of swiss cheese, and the possible problems or failures in that defense are represented by the holes in the cheese. The positive significance of this theory lies in: (1) linking a series of causes and consequences of an accident, forming a complete chain of accident causes, and enabling people to have an accident prevention route; (2) identifying the two direct causes of an accident; and (3) a partial accident prevention method is provided, that is, the unsafe action and the unsafe state are eliminated. 88 per cent of construction accidents are caused by unsafe acts of persons, 10 per cent by unsafe. conditions and finally 2 pe r cent by ‘ acts of god’. it is interesting to notice that.

To apportion blame, and by extension liability, for an accident it is necessary to decide causality, who caused the accident and how it was caused. the same requirements apply to the preventative management of such potential accidents, except blame is assigned post hoc, after the event, whereas preventative management is essentially proactive and obviates the need for blame. This paper proposes a human factors model of workplace accident causation. particular attention is given to merging traditional human factors considerations with those related to self protective be.
