ARM 401 Chapter 2 - Part 2Accidents happen. There's no way to avoid that. But one marginal benefit that accidents
offer is:
In providing an opportunity to examine why they happened and, through that, perhaps the
ability to learn how to avoid a repeat occurrence in the future.
Often, an accident investigation focuses on either:
An unsafe act or an unsafe condition.
But the causes of an accident can be much more complicated than that, and:
Multiple factors could be involved.
It's up to risk management professionals to look past the surface of an accident to find:
Its root cause and to prevent repeat occurrences in the future.
The three basic categories of accident causes are:
Poor management, safety policy, and personal or environmental factors.
There are five theories or approaches to understanding accident causation, relating to
elements that are:
Direct, indirect, and basic:
The five theories or approaches to understanding accident causation:
Sequence of events, A K A domino theory. Energy transfer theory. Technique of operations
review T O R approach. Change analysis. Jobb safety analysis.
The sequence of events theory is A K A:
The domino theory.
The sequence of events theory proposes that:
These five accident factors can form a chain of events that, like dominos, lead in succession
to the resulting accident and injury:
The five accident factors in the sequence of events theory are:
Ancestry and social environment. Fault of person. An unsafe act and/or a mechanical or
physical hazard. Poor maintenance of surroundings. The accident itself. The resulting injury.
, Some examples of ancestry and social environment, are:
Inherited psychological disorders and dysfunctional social environments.
Some examples of fault of person, are:
Impulsiveness, violent temper, nervousness, or a refusal to adapt to safe practices.
Some examples of an unsafe act and/or a mechanical or physical hazard, are:
Improper use of machines or equipment.
Some examples of poor maintenance of surroundings, are:
Slippery floors or faulty railings.
Because each of the earlier links of the domino theory leads directly to the next:
Removing any of the four factors that occur before the injury should, in theory, prevent the
resulting injury from occurring.
The third domino is:
The unsafe act and/or mechanical or physical hazard.
Doing this, is usually the best way to break the accident sequence and prevent injury or
illness:
Removal of the third domino, the unsafe act and/or mechanical or physical hazard.
Considering its emphasis on human fault, this theory is most applicable to situations within
human control:
The domino theory is most applicable to situations within human control.
Because the domino theory is most applicable to situations within human control, this theory,
therefore, has limited applicability to:
Accidents caused by natural disasters.
Although people can attempt to protect themselves and their property from a natural disaster
such as a hurricane:
Preventing the cause of the accident is not within their control.
However, the domino theory is well-suited to accidents caused by:
