What is accident causation model?
The Accident Causation Model (or “Swiss Cheese Model “) is a theoretical model that illustrates how accidents occur in organisations. It postulates that the typical accident occurs because several (human) errors have occurred at all levels in the organisational hierarchy in a way that made such accident inavoidable.
What is incident causation?

What are the three phases of the domino theory?
The chain of events consists of the following sequential factors: ancestry and social environment, an individual’s mistake, an unsafe action and/or physical hazard, the actual accident, and an injury as the result of the preceding factors.
What is the Heinrich model?
In his 1931 book “Industrial Accident Prevention, A Scientific Approach”, Herbert W Heinrich put forward the following concept that became known as Heinrich’s Law: in a workplace, for every accident that causes a major injury, there are 29 accidents that cause minor injuries and 300 accidents that cause no injuries.
What is the difference between linear and non linear accident models?
There are linear models which suggest one factor leads to the next and to the next leading up to the accident , and complex non linear models which hypothesise multiple factors are acting concurrently and by their combined influence, lead to accident occurrence.
What are theories of causation?
The central idea behind probabilistic theories of causation is that causes change the probability of their effects; an effect may still occur in the absence of a cause or fail to occur in its presence.

What is the theory of multiple causation?
Multiple causation theory is an outgrowth of the domino theory , but it postulates that for a single accident there may be many contributory factors, causes and sub-causes, and that certain combinations of these give rise to accidents.
What is human factor theory?
The human factors theory of accident causation attributes accidents to a chain of events ultimately caused by human error. It consists of three broad factors that lead to human error: overload, inappropriate response, and inappropriate activities.
What is the definition of domino theory?
The domino theory was a Cold War policy that suggested a communist government in one nation would quickly lead to communist takeovers in neighboring states, each falling like a perfectly aligned row of dominos .

What is accident ratio?
There is a great deal of data about accidents and the severity of their consequences and this has led. researchers to look for a statistical link between different levels of severity and the number of times they. occur.
Who is the father of safety?
What is the Heinrich ratio?
Heinrich proposed a specific ratio relating the number of near miss incidents and minor harm injuries to a single major harm injury in the form of 300:29:1, respectively, and depicted the ratio in the form of a “safety triangle.” Although Heinrich’s ideas have been very influential to OSH policy and management, their
