Accident Causing Theory in Construction Safety Management

The accident rate of construction industry has been very high, so the construction safety management is particularly important. Accident causation theory is a common theory, which can improve the safety management of construction. Based on this, this paper studies the application of accident causing theory in construction safety management. This paper compares the common accident causing theories, selects the relatively more advantageous "4M" theory, applies it to the construction safety management, establishes the safety evaluation system, selects two unfinished projects in the construction site for analysis, and selects the safety fuzzy comprehensive evaluation model in the evaluation method. This study found that after applying the accident cause theory, the human factor index score of item 1 is 91, the material factor index score is 86, the management factor index score is 89, and the environmental factor index score is 91. The human factor index score of item 2 is 90, the material factor index score is 85, the management factor index score is 86, and the environmental factor index score is 88. The security of both projects has changed from general to safe. In this way, we know that the application of accident cause theory can effectively improve the safety of construction.
