Abstract: Heinrich (1980) claimed that safety education primarily relates with 88 percent of safety accidents, and secondarily relates with safety accidents. For this reason, safety education is of critical importance. However, while many studies have been performed on safety education in Korea for the prevention of safety accidents, few studies have been done on safety education currently performed in other countries. Therefore, in this study, a comparative analysis was conducted on the safety education cases of three different construction companies that are currently carrying out overseas construction projects. With this study, we identified four shared features and some differences in the safety education of each company.

Abstract: According to the industrial accident statistics reported by the Korea Occupational Safety and Health Agency, about 10 percent of accidental work site deaths were caused by defect or misuse of safety equipment [1]. For this reason, safety equipment should be understood properly to prepare a plan for its appropriate use [2]. Therefore, this study aims to identify the related problems by studying the understanding of safety equipment for construction works at sites. To conduct this study, a questionnaire survey of 100 construction workers in apartment building construction sites in Jeolla-do was carried out. This study reveals that the education on safety equipment is of help for construction workers, but they do not have a deep understanding of it in actual use.

Abstract: With the rapid development of construction industry progress, construction safety is paid more attention by more and more people. At present, construction safety has become the main problem which restricted the construction industrys development. It not only reflects construction enterprises management level, but also the economic efficiency of enterprises. Therefore, adopting prevention measures about construction industry is worth researching and discussing. This paper introduces the present situation of safety management in construction sites, then analyses the major safety management problems. Finally, it pertinently advances effective countermeasures on the basis of Safety First, Prevention First, Comprehensive Treatment to achieve the aim at reducing the construction safety accident rate to the greatest extent.

Abstract: Construction safety accident has occurred frequently and accident death toll has been high. Investigate its reason, mainly in the low level of construction enterprise safety accidents emergency management. Strengthen construction safety emergency management can effectively reduce the life and property losses, and to ensure the sustainable development of construction enterprises. We put forward a construction safety emergency decision support system based on ontology and CBR method. Then we described its work processes and use the foundation pit engineering as an example to explain the knowledge representation and the ontology similarity case retrieve matching method. Finally, we give the method to realize the system so as to reach the purpose that improved the building enterprise emergency management capacity effectively.

Abstract: During the construction period of roller compacted concrete (RCC) dam, the scientific control of safety and progress is very important. It can provide guarantee for realizing the high-standard, high-intensity, continuous and rapid construction. First, through analyzing the coupling relationship between construction safety and progress, the procedure of progress control coupling safety analysis was proposed. Second, a mathematical model for coupling control of construction safety and progress that considers complex constraints was developed. Third, a construction simulation system considering safety factors was developed. Finally, these methods were applied to a practical project, and can provide new theoretical principles and technical support for safety and progress control in the RCC dam construction process.

Abstract: Thirty-nine influential factors of construction safety are identified in this study, and then five categories of respondents estimate their influential degrees through a questionnaire survey. In order to analyze these factors more accurately, a fuzzy factor analysis model (FFAM) is proposed. After calculating fuzzy eigenvalue, fuzzy correlation coefficients and factor loadings matrix in the model, seven different common factors are extracted. Finally, the author put forward several effective measures for improving construction safety based on these common factors.

Abstract: Construction hazard identification is one of the fundamental steps in construction safety management therefore identifying hazards and determining their severities of consequences are extremely important. The aim of this study is to investigate and rank the construction hazards in order of the severity of consequences. The data for this study were collected using a questionnaire survey, distributed among respondents randomly selected from construction sites within Malaysia. The results of this study indicated that the most critical construction hazards are Awkward postures, Forceful exertions and Physical injury hazards which originate from process of work and manual handling of operations and equipments. On the contrary Blue green algae and Fungi are the least critical construction hazards which are not critical threats to the safety and health of construction workers. In addition to training and educational purposes, the results of this study can be used in preparing appropriate construction safety and health plans.

Abstract: dentifying the root causes of construction accidents has indicated that not only contractors but designers and architectures are capable of influencing construction workers safety. The aim of this study is to investigate and prioritize factors affecting construction hazards in the design phase. To achieve the aim of this study, a questionnaire survey was distributed among respondents randomly selected from construction sites within Malaysia. Relative Importance Index method was used to prioritize factors in order of level of effect on construction hazards. The results indicated that Lack of designers safety knowledge, Lack of designers knowledge about construction processes and Late involvement of constructors in the design process have the highest level of effect while Lack of safety organizations which evaluates the safety level of design and Few application of components' prefabrication have the lowest level of effect on hazards in the design phase of construction projects.

Abstract: It has been suggested that many construction workers are never properly educated on the meaning of safety signs. In particular, considering that any safety accident can lead directly to a serious disaster, understanding safety signs is a critical part of safety management. Therefore, the purpose of this study is to analyze construction workers’ awareness of and understanding of safety signs. The research found that most construction workers perceived that safety signs play an important role in preventing safety accidents. However, almost half of construction workers did not understand what construction safety signs convey, which indicates an urgent need for education on safety signs at construction sites.

Abstract: The risk of bridge and tunnel engineering in construction stage is a main subject which must be faced by bridge and tunnel engineer. Risk evaluation can analyze the happening possibility of construction safety accident and the consequence and loss caused by the accident. The research summary of risk evaluation method of bridge and tunnel construction safety is generalized in this paper. The main methods of risk evaluation at present are extrapolated, and the quality of each method is analyzed. The word of this paper will provide favorable reference for further research on risk evaluation of construction safety of bridge and tunnel engineering.
