Multiple factors accident theory

Multiple Causation Accident Theories Multiple Factors Theory... 

In multiple factor theories, several factors combine in random or some logical fashion and lead to accidents. Factors may include any of the three elements of a hazard activities, conditions, and circumstances. 

Multiple factors theories attempt to identify specific workplace characteristics that reveal underlying, and often hidden, causes of an accident by pointing to existing hazardous conditions. When viewed as a whole, the characteristics can direct the investigator s attention to the specific causes of an accident. 

The Interim Decay Storage (IDS) facility provides storage for fresh or irradiated fuel for the Fast Test Reactor (FTR), A series of one- and two-dimensional transport and diffusion theory calculations was made -to establish the hUective multiplication factor of the IDS facility when fully loaded with initial driver fuel for the FTR, and also to establish the upper plutonium content of fuel that can be stored in the facility. No consideration was given in these analyses to accidents in which sodium coolant would be lost or fuel spacing changed. 

One variation of the Multiple Causation Theory is R. J. Firenzie s Theory of Accident Causation. Firenzie s theory is based on interaction among three components person, machine, and environment. Human variables of information, decisions, and perception of risks combine with machine hazards and environmental factors affecting the likelihood of an accident. 

Today, we know that behind every accident there he maty contributing factors, causes, and subcauses. The theory of multiple causation is that these factors combine together in random fashion, causing accidents. If this is tme, om investigation of accidents ought to identify some of these. 

This theory promotes the idea that accidents result from various hazards or other factors interacting in some manner. Accident prevention professionals use different terms to describe these factors. Some refer to the factors as primary and secondary causes, whereas others use terms such as immediate and contributing causes, surface and root causes, or causes and subcauses. Most investigators agree that accidents happen due to multiple and sometimes complex causal factors.
