  • This study analyzed the accidents and researched on risk of the actual condition in roof works. This study revealed that 68% of accidents in roof works occurred on small sized construction sites. And 79% of accidents are caused by fall. It is simply because most laborers do not wear the safety harness and the mounted equipment is not properly installed. According to our research, we realize that most of roof works have some risk of the fall accidents. Most of roof working sites have the danger of falling at ladder and temporary walkway. In oder to prevent accidents in roof works, the basic rule such as wearing the safety harness must be followed.

  • The aim of this paper is to identify and rank the main causes of fall accidents from scaffolding according to their relative importance as perceived by project managers and site engineers in construction projects in the Gaza Strip. A total of 50 questionnaires were distributed to project managers and site engineers, 35 questionnaires were received yielding 70% response rate. A total of 33 factors that cause fall accidents in scaffolding were identified through a literature review and consolidated by a pilot study. These factors were categorized into six groups: factors related to erection, factors related to the staff (Scaffolders), factors related to loads, factors related to the personal safety, factors related to the workers behavior, factors related to the personal competencies. The results indicated that factors related to the workers behavior are the major factors that caused fall accidents from scaffolds. The results revealed that the top ranked factors which caused falls accidents from scaffolding were: absence of personal protective equipment (PPE), missing ladders, wind loads, disguised the design code, lack of proper assembly or inspection, overhead tools and materials, climbing and neglect using ladders, lack of guardrails, missing bracing and working during fatigue. These findings would help contractors to understand the top factors that caused fall accidents so that they can take them into consideration in safety planning in order to minimize the possibility of their occurrences.

  • The number of industrial accident victims in the construction industry accounts for 1/3 of those in the entire industries and about 30% of the total compensation costs are spent in the construction industry. As such, the construction industry is a typical industry causing numerous safety accidents. This study analyzes the status of industrial accidents in small scale construction sites to build maximum five-story buildings by examining statistical data for the past five years, investigating those construction sites and conducting interviews with the workers. This study also seeks the causes of and measures for industrial accidents in the small scale construction industry through comparison with relevant systems. The findings are as follows: (1) To reduce hazard rate, shaping the working environment and safety measures that take into account the physically weak classes of the middle aged and the aging are urgently required, because 62.9% of the industrial accidents in the construction industry occurred to those who are 50 years of age or older. (2) The hazard rate at small scale construction sites with less than 10 construction workers accounts for 55% of that of the entire industries. The government, in this context, needs to support finance or technology and improve system by selecting the small scale construction sites, where industrial accidents occur frequently. (3) Because the hazard rate of unskilled workers with less than 6 months of work experience accounts for 90.95% of the total, safety education needs to be concentrated on those unskilled workers. (4) The relevant standards need to be segmented and revised and bolstered, given that 64.79% of death disaster in the construction industry occurs in the temporary structures including scaffolds and ladders.

  • The construction industry is suffering from a large number of fatal accidents. As many field works are being conducted in a dangerous condition such as working at height and adverse weather, they are always exposed to safety accidents with high frequency and severity compared to other industries. Such risk is even larger in small construction sites, but studies that focus on combinatorial factors leading to fatal accidents in small construction sites are lacking. Thus, in order to reduce the fatal accidents in the construction industry, this study analyzed 1,438 occupational death accidents cases in small construction sites and, then, conducted the association rule analysis to extract ten combinatorial factors that frequently led to fatal accidents in small construction sites. Based on the extracted association rules, this study also discussed possible countermeasures to reduce the fatal accidents. The results were explained to experts, who agreed on the results of the study. This study contributes to the construction safety management theory by providing a detailed analysis of fatal accidents in small construction sites that can be used for developing and deploying safety policies and educations for small construction site workers.

  • According to 'The Analysis of Industrial Accidents in 2016' by Ministry of Employment and Labor, the number of deaths caused by accidents in the construction field is 391, accounting for 47% of 826 industrial fatalities in all industries. The breakdown of the 391 fatalities of the construction industry shows that 'struck by an object' accident had 30 fatalities, the 3rd in frequency following falling (235) and crashing (32) accidents. This study aims to explore ways to reduce the 'struck by an object' accident with emphasis on safety education and certificate system for rigging and slinging works. This study reviews literature on rigging and slinging works and analyzes 'struck by an object' accidents. The rules and regulation on the rigging and slinging works are also reviewed both for Korea and other countries with best practices in construction safety such as Singapore, Japan, U.K., and U.S. The rigging and slinging certificate systems of those countries are also reviewed to find any advantage in the construction safety management. In addition, a pilot rigging and slinging certificate system was executed in one of domestic construction site followed by two surveys: one on the riggers who participated in the pilot operation and the other on general managers in domestic construction sites. Based on the analysis of the 'struck by an object' accidents and pilot operation, this study proposes a rigging and slinging certificate system to reduce accidents, enhancing safety condition of construction sites. The certificate system was proposed in a way to accommodate working practice of construction sites. Depending on rigging careers and a crane load capacity, riggers are eligible to apply either basic or master certificate which makes difference in the level of rigging works. The safety condition of rigging and slinging work could be substantially enhanced if workers, managers, supervisors, administrators, and policy makers work together consistently.

  • With the average life expectancy increasing thanks to better standards of living and medical technology, the number of elderly construction workers in construction sites rises every year to surpass the 450 thousand people in the construction industry (24.7% of all employees in the construction industry). Similarly, the percentage of fatal accidents involving elderly workers has stood at 41~46 percent for the past five years; note that this is significantly higher than the other age groups, making safety measures for dealing with this issue a matter of urgency. This study sought to propose appropriate safety guidelines for elderly construction workers aged 50 years and over by examining the changes in their physical and psychological functions and through the subsequent analysis of the current status and causes of fatal accidents involving them. The guidelines targeted ferroconcrete construction where accidents occur quite often; construction was classified into mold construction, reinforcing rod construction, and concrete construction. Mold construction was further classified into preparation, carry-in, processing, assembly, and disassembly, and reinforcing rod construction, into preparation/transport and processing/assembly. Safety guidelines for each process were presented by dividing them into three aspects considering the changes in the physical and psychological functions according to their ages and type of accident causes: work environment improvement, machinery and equipment improvement, and work method improvement.
