Accident theories aim to clarify the accident phenomena，and to explain the mechanisms that lead to accidents. All modem theories are based on accident causation models which try to explain the sequence of events that finally produce the loss.

He concluded that unsafe acts, unsafe conditions，and accidents are all symptoms of something wrong in the organizational management system. Furthermore, he stated that it is the top management who is responsible for building up such a system that can effectively control the hazards associated to the organization’s operation. The errors done by a single person can be intentional or unintentional. Rasmussen and Jensen have presented a three-level skill-rule-knowledge model for describing the origins of the different types of human errors. Nowadays，this model is one of the standard methods in the examination of human errors at
