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.

The proportion of elderly people over 50 years old in the total population of Korea increased from 29.2% in 2010 to 34.8% in 2015. As a result, the proportion of construction workers over 50 years old compared to the total construction workers increased from 20.1% in 2010 to 27.0% in 2015. In this aging society, the construction industry has faithfully carried out the business objectives and budget execution of measures to prevent disasters against elderly workers, but there was a limit to the fundamental prevention of disasters. Because the countermeasures for the prevention of construction disaster are considered on all ages rather than elderly workers. This study investigates the safety and health status of elderly workers at construction sites and suggests the plans to reduce disaster. In particular, to reduce disasters of rapidly growing elderly workers, the authors reviewed the related literature and safety regulations, statistics on the causes of industrial accidents, statistics on the status of industrial accidents, and applied to 3,549 workers who participated directly in the construction activities. The authors surveyed the actual situation of safety and health, presented the comprehensive disaster reduction measures by analyzing the current status and problems of disaster prevention projects. If the countermeasures proposed in this paper can be reflected in the actual policy, it is expected that the countermeasures will be possible to reduce the disaster of the elderly workers at the construction site, which is gradually increasing.

With the aging of the population and the slowdown of the job market, elderly workers make up a large portion of the construction workforce. Also, due to the nature of the construction industry, where outdoor work is frequent, the weather has a more sensitive impact on elderly workers than on younger ones. The study aims to analyze the degree of weather risks exposed to elderly workers in the construction industry using the measure of work loss days. To that end, construction accidents that affected 28,514 elderly workers in seven cities from 2012 to 2016 (a total of 12,789 days) were analyzed to calculate work loss days per different weather factors. The results show that the elderly workers were seriously affected when the temperature was between $-12^{\circ}C$ and $-10^{\circ}C$, humidity between 55% and 60%, precipitation between 128mm and 181mm, and wind speed between 5.5m/s and 6.5m/s, with the highest work loss days. The combined effects between the weather factors were also analyzed to identify the conditiosn that leaded to high work loss days of elderly workers. This study contributes to effective safety management and pleasant working environment between weather factors and shedding light on the relationship between weather factors and work loss days of elderly workers.

According to the Ministry of Employment and Labor's industrial accident death statistics, the number of accident deaths in the construction industry increased by 30 people year-on-year to 458, with 77.3% of the accident deaths aged 50 or older and 41.9% aged 60 or older. This study conducted and analyzed a survey to identify safety education, protective equipment, and safety consciousness for 68 elderly workers working at construction sites. As a result, the necessity of diversifying safety education using visual data was confirmed to reconsider the contradictory safety consciousness of elderly workers. It also confirmed the need to improve protective equipment, such as providing protective equipment suitable for individual bodies and periodic replacement, for workers who are passive in wearing protective equipment despite the high need for protective equipment.

Purpose: Construction sites are currently facing a socialization problem as the incidence of thermal disease-related disasters increases due to summer heat waves, exacerbated by factors like the concentration of middle-aged and older workers and global warming. The reason why construction sites are particularly vulnerable to heat waves is that there are many outdoor work, which is the peculiarity of the construction industry, and most of the construction workers are elderly. This study analyzes disaster statistics of workers at construction sites for five years to investigate the occurrence of thermal diseases and analyze factors through disaster cases to provide basic data for future disasters to be reduced. Research design, data, and methodology: According to the Construction Workers' Mutual Aid Association, as of June, more than 60% of the construction workers working in the field were in their 50s and 60s. More than 24% are in their 60s and older. Thermal diseases caused by heat waves occur when exposed to high heat or strong sunlight for a long time, accompanied by headaches and dizziness. The problem is that many elderly people have underlying diseases, so if they lose consciousness, they cannot easily recover and are likely to die. Results: According to industrial accident statistics, 182 people were injured by heat-related diseases in the summer from 2016 to 2021, of which 29 died. In particular, in the construction industry, which has a lot of outdoor work, 87 people were injured and 20 people died. Conclusions: In order to prevent heat diseases caused by outdoor work, it is emphasized that exposure time is controlled, and sufficient rest and hydration are essential. Rest, water, and shade are in line with the three principles.

Since the Act on Punishment of Serious Accident has been implemented, the role of construction companies in safety and health and the responsibility of CEO are strengthened. However, serious accidents still occur. Due to population decline and young people's reluctance into the construction industry, the ratio of elderly workers and foreign workers is increasing at construction sites. In this study, a survey was conducted to identify differences in the perception of importance of smart safety technology among vulnerable groups such as foreign workers, elderly workers, and workers with health conditions. Vulnerable workers recognize the importance of smart technology in the fields of foreign language support, risk warning, and body wear monitoring, and the conclusion was drawn that smart technology should be expanded for vulnerable groups in the future.

The study measured a subway construction worker's Macpa stress by Heart Rate Variability measuring instrument and conducted a survey of Korean job stress from subway construction workers. Also, the study analyzed the relationship between Macpa stress index and Korean job stress result and suggested managing stress method for each item. According to National Statistical Office data, the first line subway in Seoul was started to open in 1974. The extended total length is 996 kilometers until 2019. Many aged workers are currently working at subway construction sites due to the avoidance of young workers since the past until now. It means that the elderly has a substantial portion among subway construction workers. The productivity has been adversely affected by health problems due to the aging of workers, job stress due to heavy work, and personal health problems. So, the regulation and policies on job stress health management are being strengthened. The data were measured Macpa stress by machine measuring heart rate variability and conducted Korean job stress survey(shortened) from Sa-sang to Ha-dan line Busan subway construction workers for analyzing the relationship. Independent variable were age, job duration, job position, employment type, working type in this study. Macpa's dependent variable was stress index and Korean job stress survey(shortened)'s dependent variables were job requirements, job autonomy, relationship conflict, job instability, organizational structure, inappropriate compensation, working place culture, and total score. SPSS 12.0 K Statistics Program was used for statistical analysis. Kruskal-wallis test, a nonparametric statistical analysis, was used because the data are difficult to be assumed as normal distribution. As a result, the paper indicated the significant correlation between Macpa stress index and Korean job stress(short version). The elderly workers presented higher Macpa index and higher job stress due to aging and heavy-duty work. The majority workers were daily workers who had unstable working condition and uncertainty about the future. The study suggested a manual that could reduce job stress for subway construction workers and future study deriving management tool through analyzing job stress factor is necessary.

Most accidents at construction sites are occurring in vulnerable groups such as new workers, foreign workers, and elderly workers. These vulnerable workers often lead to accidents due to the lack of awareness of risks. Therefore, in order to reduce accidents, it is necessary to pay attention to and manage vulnerable workers. This study attempted to identify the level of safety awareness and safety management priorities for vulnerable workers through IPA analysis. New workers should be able to adapt to the field as soon as possible, and foreign workers were found to need frequent check-ups due to language communication problems. In the case of older workers, it was analyzed that it was necessary to check their health and to check whether they were performing other tasks than the prescribed ones.

Workers who die from falls at construction sites account for about 40 percent of the total number of deaths and are the main forms of accidents. In addition, as the nation's population structure is gradually aging, the rate of aging is increasing at construction sites, and the number of crashes due to decreased physical function and cognitive ability is increasing. Accordingly, we conducted a survey on the factors affecting the fall of older workers and would like to present more fundamental measures to prevent falls, focusing on older workers who are the victims of the disaster.
