What are the sequence of accident factors in domino theory?

The original theory by G. W. Heinrich are as follows:

1. Work situation: lack of supervision, work pressures, etc...

2. Fault of person: stubbornness, recklessness, personal problems, etc...

3. Unsafe Act: short cuts, using unguarded tools, process error, etc...

4. Accident: event such as fall, pinch points, etc... that result in injuries

5. Injury: any level of injury from first-aid to catastrophic
