Theories on Common Causes of Accidents This is a short paper looking at what some theorists (Heinrich, Reason and Perrow) say about how accidents are caused. Perhaps the most influential theory of accident causation has been Heinrich's Domino Theory of the 1920s. Essentially, the theory states that and accident leading to injury or damage is the result of a five stage sequence. Each domino therefore represents a linked cause. Remove any one of them and the sequence cannot run its course, and therefore damage or injury will not be incurred. Over time, consensus has built up about the types of cause represented by each domino stage. By now, we know enough about the last two stages (the accident and resulting injury or damage), but some typical examples of the first three causes are: Work situation Fault of person Unsafe act Inadequate management control Unsafe system design Lack of suitable standards Faulty or inadequate equipment Business pressures Insufficient skill or knowledge

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
