Review Question 18
Which theory below states, "An accident is the result of a series related events: Eliminate any one event, and you prevent a future accident"?
A. Single event theory
B. Domino theory
That's Wrong. Try Again!
The correct answer is, B. Domino Theory. This explanation describes an accident as a series of related occurrences which lead to a final event that results, in injury or illness. Like dominoes, stacked in a row, the first domino falling sets off a chain reaction of related events that result in an injury or illness. The accident investigator will assume that by eliminating any one of those actions or events, the chain will be broken and future accidents prevented.
C. Multiple cause theory
D. System weakness theory
