Application of Domino Theory to Justify and Prevent Accident Occurance in Construction Sites

since the construction activities involve most complex processes and the most intensive administrative atmosphere as well, the accident events come raised in different situations and due to various causations. Most of the construction accidents originate from human errors and operation sources such as equipments and facilities in work processes. Most accidents lead to the loss of life, injuries and loss of properties. The other possible results due to the errors, unsafe acts, and unsafe conditions can be categorized in Near miss events (no result of injuries), and incidents (likelihood of injuries or loss of property). The role of a tool by which the causations and the processes can be highlighted is vital to save the projects not to be trapped. In order to recognize the reasons or the factors contributing to accidents, several theories have been developed by researchers. Domino theory as a structural map has been one of the most understandable and widely acceptable theories among the accident theories. The authorities employ it to control the factors causing undesirable events and to prevent the errors before being made. The aims of this paper are firstly, to describe the shortcomings of construction processes contributing hazardous situations. secondly, highlighting, the ways to apply Domino theory, and thirdly, to define how to establish a remedy model to prevent accidents in construction projects based on domino theory in simple statements.
