For the building construction trade, activities should be focused carefully including mortar &; painting, roof installation and steel structure engineering. The accident types happen most frequently are fall from elevation and collapse. The medium of accidents include scaffolding, bracing, roofing and open cuts. Regarding the civil engineering trade, activities should be focused carefully including foundation engineering, machinery operations and other operations. The accident types happen most frequently are other types of accidents and body collision. The medium of accidents include motor-carry machines, transportation and environment. After the foregoing critical situations COAs analysis cases, individual compile its "accident-caused " and "prevention countermeasures," the use of functional analysis "purposes-means" conceptual design questionnaire checklist classified by experts, through descriptive statistics, difference analysis to understand the respondents in the "disaster prevention measures" attitude between the effectiveness of validity, as well as different groups of "prevention countermeasures”, whether there are differences in order to verify the theoretical assumptions made in this questionnaire. The research performances "disaster prevention measures" to Kendall coefficient of concordance for the importance analysis of respondents opinions and their level of consistency, and eventually proposes primary prevention countermeasures. It is found that proper cut of the survey results found that the average score is below the average score of the basic reasons of indirect causes. For "basic cause" the study mentioned in "prevention countermeasures" the relevant provisions of the surface due to the implementation of the lack of clarity, should be more appropriate, precise specification of the regulations. Another "prevention countermeasures" the importance of the survey showed that "building construction trade-mud for plastering works-fall, tumble-scaffold, cage" and "civil engineering trade-infrastructure projects-collapse, collapse-sediment, function critical situations of the rock" in the order of importance were Questions-C6, C7, C8 and C15, C14, C12 and C13. The Kendall''s W test shows that the two critical situations are statistical significance. It means that the viewpoints of respondents are with consistency, with it’s a degree of micro-agreements correlation. Differences in attitudes of the respondents analysis showed that the respondents engaged in the project properties works will affect their attitude toward Question-C7 appraisal questions of importance. Among them, the overall appraisal of Question-C7 is lower than that of civil engineering, civil engineering may be to the majority of housing construction industry, is more attention to Question-C7 (scaffolding pedal width should larger than 40 cm. and the gap between the sheet metal and its cover should less than 3 cm.). Regarding the demonstration improvement of prevention countermeasures of occupational accidents cases, this study suggests: (1) for " accident-cause", "prevention countermeasures," should be for the engineering characteristics, status, career labor relevant units to perform operations, develop countermeasures and included case records of occupational accidents. (2) For the "basic-cause", the relevant provisions in the face of the need to be more clear. (3) The “prevention countermeasures," should be classified into primary and secondary according to the effectiveness of the district disaster prevention. (4) Unify the format and content of disaster scenarios of the three districts of labor office, and strengthen the post-disaster scene to restore order to enhance its reference value.
