Choi, Gi Heung ; Loh, Byoung Gook ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 1~6
DOI : 10.14346/JKOSOS.2016.31.1.001
Severity and frequency of industrial accidents are typically used to assess the "absolute" risk associated with the industrial machines and devices ("items") which are subject to safety certification or self-declaration of conformity. However, the "relative" risk associated with a particular item can further be assessed based on unit severity and unit frequency where the total number of item in use is taken into account. This study first attempts to estimate the total number of each item in use which was recently selected for safety certification or self-declaration of conformity. The appropriateness of such selection is recapitulated based on the relative risk involved. Analysis results indicate that depending on items, the relative risk is differentiated from the absolute risk. Recent selection of items for safety certification or self-declaration of conformity is then revisited for its validity. The relative risk based on unit severity and unit frequency of industrial accidents, together with the absolute risk, may be used to further categorize items for safety certification or self-declaration of conformity in the future.
Effectiveness and Balance of Compulsory and Voluntary Safety Certification of Industrial Machines and Devices
Choi, Gi Heung ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 7~12
DOI : 10.14346/JKOSOS.2016.31.1.007
This study first focuses on the quantitative evaluation of both compulsory and voluntary safety certification of industrial machines and devices. Based on the results of statistical analysis, effectiveness of those safety certifications were confirmed. In order to reduce both the frequency and the strength of industrial accidents associated with industrial machines and devices, major target of safety regulations needs to be shifted from users to manufacturers. Adjustment of industrial machines and devices which are subject to compulsory safety certification and implementation of risk assessment are further suggested. As for the voluntary certification, reestablishment of the concept of voluntary safety certification and balance between compulsory and voluntary certifications is discussed. Voluntary safety certification is further suggested as a mean to manage safety of industrial machines and devices which are not subject to any safety regulations.

KTX wheelset bearings have thus far been maintained in accordance with the maintenance system of French national railway company, SNCF. The overhaul cycle time (OCT) of KTX wheelset bearings is now 1.4 million km in mileage. This value, however, has not been validated in Korea that has much different railway environments with France. In fact, it is impossible to validate OCT of wheelset bearings directly because they are disassembled and cleaned only when some faults are detected. In this paper, the accuracy of the current OCT value was evaluated indirectly by investigating the effect of grease lubricants on the bearing life. Five grease samples (one new and four aged greases) were used in this study. Four aged greases of different conditions were obtained from four wheelset bearings whose mileages were about 0.3, 1.2, 1.3, and 1.8 million km, respectively. Each grease sample was then injected into the RCF (Rolling Contact Fatigue) tester and fatigue lifetime was experimentally estimated. In addition, the wt% of Fe in each grease sample was analysed. The experiment results reveal that the bearing lifetime is inversely proportional to the mileage of grease sample while the wt% of Fe increases with the mileage of grease sample. Based on the experimental results, it can be concluded that the current OCT value is appropriate for the first overhaul of wheelset bearings. However, further validation is required to determine the second and third OCT values.

Rubber parts are widely used in many applications such as dampers, shock absorbers, and seals used in railway and automotive industries. Much research has thus far been conducted on property estimation and life prediction of rubber parts. To predict the service life of rubber parts at room temperature, most prior work adopts the well-known Arrhenius model that needs the accelerated life test in high-temperature conditions. However, they may not reflect the actual conditions of use that rubber parts are usually used under a specific strain condition during long period of time. In this context, we propose a method for the life prediction of rubber parts in actual conditions of use. The proposed method is based on the accelerated life test using stress relaxation during which three relatively high elongation percentages (100%, 200%, and 300%) are applied to the rubber specimens. Rubber specimens were prepared in accordance with KS M 6518 standard and three stress relaxation testers were fabricated for actual experiments. Finally, a inverse power model for life prediction was derived from experimental results. The predicted life was compared with the actual test life for validation.

Cho, Jae-Ho ; Hwang, Cheol-Hong ; Kim, Joosung ; Lee, Sangkyu ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 25~32
DOI : 10.14346/JKOSOS.2016.31.1.025
A sensitivity analysis of FDS(Fire Dynamics Simulator) results for the input uncertainty of heat release rate (Q) which might be the most influencing parameter to fire behaviors was performed. The calculated results were compared with experimental data obtained by the OECD/NEA PRISME project. The sensitivity of FDS results with the change in Q was also compared with the empirical correlations suggested in previous literature. As a result, the change in the specified Q led to the different dependence of major quantities such as temperature and species concentrations for the over- and under-ventilated fire conditions, respectively. It was also found that the sensitivity of major quantities to uncertain value of Q showed the significant difference in results obtained using the previous empirical correlations.

DOI : 10.14346/JKOSOS.2016.31.1.033
Coupling systems under train`s collision should take the impact by absorbing the impact energy caused from the collision, so the systems are very important parts for the safety of the trains. However, it is not easy to evaluate the performance of the system because it requires a huge testing facility, which is able to control the impact and to handle many safety issues. In this paper, test results are provided, which are obtained from collision tests of a single train having a coupling system in the front, and the results are analyzed in order to understand the characteristics and the dynamic behaviors of energy absorbing materials in the coupling system, such as a hydraulic buffer, and two rubber buffers. The results show that the force of each component could be empirically described by the compression displacement and velocity. The analyzed results will be applied to simulation models, and advanced studies wouuld be available if the simulation models are well validated with the test results.

The rolling stock is composed of several cars. In order to operate in combination, it is necessary to connect the device, called coupler, between the rolling stocks. When the collision occurs between cars, couplers should be able to absorb the shock. Urban railway has used only rubber absorbers. But recently, the hydraulic buffer has been considered in general railway. In order to know the performance of the buffer it should be conducted to experiments. But whenever this combination change, we should experiments to know a lot of the dynamic behavior of each coupler. These experiments are generally replaced by the simulation, since a lot of time and cost consuming. The quasi-static map of hydraulic buffer obtained by the experiments is required for the simulation. However, the experiments for obtaining such a quasi-static map is costly and time consuming. In this paper, it proposes a method for deriving the quasi-static map of hydraulic buffer from the theoretical model.

Kim, Youngjin ; Kim, Jaehyung ; Kim, Sungju ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 48~53
DOI : 10.14346/JKOSOS.2016.31.1.048
This paper deals with analysis of complex grounding system using electromagnetic simulation method. Electrical devices could be damaged by transient voltage such as a lightning surge. Therefore the measures to protect the equipments from transient, such as a lightning are required. The ground system is important in this respect. The representative parameter of grounding system performance is earth ground resistance. Precise prediction of earth resistance is required, because it is difficult to modify and change after the completion of the grounding system construction. Numerical modeling is often used in numerical analysis to identify the electrical characteristics of the grounding system. However complex systems are difficult to predict grounding characteristics by numerical analysis. If the total electric field of the earth in general is similar to the antenna model, in that the incident electric field and expressed as a sum of the scattering field. In this study, the electromagnetic field simulation tool "ANSYS HFSS" module containing the antenna model was used to analyze performance of ground system. Both the simple and complex grounding system were analyzed by simulation tool and experimental method. As a result simulation method is effective to predict performance of a complex ground system.
Impermeable Standards for the Concrete Bottom of Dikes for Crude Oil Storage Tanks
Shin, Changhyun ; Park, Jai Hak ; Yoon, Junheon ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 54~60
DOI : 10.14346/JKOSOS.2016.31.1.054
The bottom of dikes must be kept impermeable to control hazardous chemicals spilled from storage tanks. Currently, insufficient related chemical control laws lead to a possibility to spread through the bottom. Generally, due to the high cost of installation and periodical maintenance, many businesses prefer to install the bottom with general concrete. But, since the impermeability of concrete is dependent on the kind of materials and chemical reaction, all concrete cannot be considered as impermeable material. Thus, it is necessary to make the installation standards of the dike bottom clear in order to avoid the argument over the impermeability and prevent the chemical accident. This study has suggested the standards of impermeable concrete by conducting 7-day exposure test to crude oil with the pilot dikes. The results have showed that the standards have the better impermeable performance compared with the germany standard, which have been penetrated at the maximum penetration depth of 1.9 cm. This study is expected to contribute to both the risk reduction of penetrating into the bottom and the cost reduction of spending to make the bottom of dikes impermeable.

Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 61~65
DOI : 10.14346/JKOSOS.2016.31.1.061
In this study, we considered the ignition possibility for the shredded thermoplastic elastomer at the fire ground loaded the waste TPE. The average moisture content of the TPE sample was almost 0.33 wt.% at
and the range of ignition point was
approximately. In addition, we analyzed the change of weight and calorie the TPE sample according to temperature variations using the TG-DTA analyzer. As a result, the weight loss occurred twice in
, and we found the second weight loss temperature range was the ignition point of TPE. Also, we conducted the spontaneous ignition tests of TPE for the wet and dry samples and we confirmed that the possibility of spontaneous ignition of TPE was very low. The elapsed time and humidity had little influence on the spontaneous ignition of TPE in this experimental conditions. In conclusion, the spontaneous of the shredded waste TPE in this study.

Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 66~73
DOI : 10.14346/JKOSOS.2016.31.1.066
Lyocell fibers were used as a precursor in order to improve yield and strength of cellulose-based precursor while manufacturing activated carbon fiber(ACF). Lyocell fibers as a precursor for the preparation of ACF were surface-modified by reaction with 3-aminopropyltriethoxysilane(APTES) and pre-treated with KOH and H3PO4. Using aforementioned precursor, ACFs were prepared by a series of stabilization, carbonization and activation process at high temperatures. On each process, FT-IR, TGA, UTM and SEM were used to observe fibers` physical properties including structure and porous surfaces. FT-IR results proved that surface modification was achieved during stabilization, carbonization and activation process. TGA results during carbonization process found that surface modified fibers with APTES 0.02 mol(A2) showed higher thermostability, and extended pre-treatment increased yield. Especially, yield was found to have an increase of 10~20 wt% with surface modification during activation process. UTM results showed that tensile strength has the same order of concentration of APTES after surface modification, however, was found to show lower tensile strength than lyocell fibers after stabilization process. SEM results revealed that more homogeneous porosity control could be proceed after modifying the surface for the effective removal of hazardous substances.

Chung, Jee-Seung ; Jeon, Jun-Chang ; Park, Jin-Seok ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 74~80
DOI : 10.14346/JKOSOS.2016.31.1.074
In this paper, structural characteristics for an extradosed prestressed concrete box girder bridge are investigated in terms of selective parameters. These parameters are mainly associated with the structural details of the extradosed bridge and derived from currently available literatures regarding previous design drawings. The analyses have been carried out using general-purpose structural analysis program, RM-Space Frame. The parameters evaluated for the present study represent the most salient features of the extradosed bridge and are as follows; 1) span length ratio(side-span length to center-span length), 2) boundary condition of girder, 3) height of pylon, 4) anchorage location of external cables and 5) girder stiffness. The analytical predictions indicate that span length ratio and pylon height are reasonably adequate in the range of 0.55 to 0.60 and
respectively for the bridge under consideration. Also, demonstrated is the boundary condition of girder, in which rigid-connection details give more efficiency than the continuous details. In addition, considering structural characteristics of the extradosed bridge, it is desirable that the girder stiffness should be determined by the stress range of external cables rather than bending moment of girder.

Park, Kyunghwan ; Kim, Yuchang ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 81~86
DOI : 10.14346/JKOSOS.2016.31.1.081
The WMSDs are known to occur more in upper extremity than lower extremity, and such a ratio is increasing each year. The motions or repeated work requiring excessive strength beyond worker`s maximum grip strength were known as a major cause of the WMSDs in upper extremity. To prevent the WMSDs in upper extremity, research on the grip strength characteristics analysis of field workers that can be used as basic data for work design and manual tool design is needed. The purpose of this study is to identify various variables affecting grip strength and is to find out the impacts of grip strength on WMSDs. This research measured the grip strength of 327 field workers at Heavy Industries, and also conducted a questionnaire survey on individual characteristics and job characteristics. As a result of analyzing grip strength, the grip strength was statistically significant (P<0.1) according to the body surface area (BSA) of the research subjects. The differences between percentile groups of grip strength were statistically significant (P<0.1) according to pain levels of hand/wrist/finger and arm/elbow. The comparison results between the average grip strength of Korean adult males and the average grip strength of the survey-targeted heavy industry workers show that the average grip strength of the heavy industry workers was higher by 9.75 kg. This study analyzed relationship between grip strength and the pain levels of hand/wrist/finger and arm/elbow, and compared the findings in this study with those of existing preceding studies. Also, this research comparatively analyzed the grip strength of Korean adult males and survey-targeted heavy industry workers. The findings of this study can be used as useful data for ergonomic work design and manual tool design to prevent WMSDs at industrial worksites, given that almost no data on the grip strength of workers in the industrial sites are found in Korea.

Recently, as Korean industrial structure is moving to the service job, the number of workers engaged in the service job is increasing slowly. According to the statistics by Ministry of Employment and Labor announced in June, 2013, the number of service job workers in Korea was 7,477,135 which accounted for 48.4% of total workers. The trend of this service job is expected to increase continuously in the future. According to the 2013 statistics by Ministry of Employment and Labor, the number of industrial accidents victims of industrial accidents in the service job was 30,526 which was the biggest number among the entire businesses. The victims in the service job accounted for 33.2% among the total number of industrial accidents and represented more than those in the manufacture and construction industry. The service job had various works and employment patterns and most service jobs are petty and are small-sized establishments and it is difficult to try voluntarily to prevent the industrial accidents. However, Korean occupational safety and health act was enacted in accordance with the construction and manufacture in which industrial accidents occurred frequently in the past. The support of the government for the industrial accident prevention is focused on the construction and manufacture. Therefore, the current service job is placed on the blind spot of the safety management. Raising the safety awareness of workers through the safety education is the most important in order to prevent the industrial accidents of the service job with many conventional/repeated disasters such as the conduction by a simple mistake. Accordingly, this study analyzed the features and accidents of the domestic service jobs through the literature survey and analyzed the institutional devices for the safety management of the domestic service job, and the safety management cases of foreign service jobs and compared with domestic systems. Considering demands for the basic safety education for service job workers, a questionnaire was conducted targeting the service job workers and the execution plan of the basic safety & health education targeting the service job workers was carried out through the brainstorming of trainers of worker in the service job.

Park, Je Jin ; Seo, Im ki ; Kang, Dong Yun ; Lee, Jae Hoon ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 95~104
DOI : 10.14346/JKOSOS.2016.31.1.095
In general, the crash reduction effect of the rumble strip is reported to be about 30% in Korea, while it is about 40-60% in the United States. However, the effect is erroneously overestimated because the simple comparison was only made before and after the installation. Accordingly, this study will reassess the crash reduction effect of the rumble strip. The study will also examine the former`s geometric characteristics as well as its effect on the causes of the crash. This study analyzed the crash effect while taking into consideration the changes in the horizontal and vertical alignment, including the width of pavement shoulders, using the crash data for two years before and after the installation of the rumble strip. The types of crash caused by the rumble strip were identified using the classification discriminant function. The crash effect on the rumble strip is estimated to be 28.3%, but the pure effect, with the exception of the effect by other elements, was analyzed to be 7.4%. For each expressway design element, the downhill section (2.0-3.0%), the section with less than 3,000 m and more than 10,000 m of the curve radius, and the section with less than 3.0 m of the pavement shoulder width were found to be effective in crash reduction. For each cause of crash, the rumble strip was analyzed to be effective in the reduction of crash caused by "not keeping the safe distance", "sleeping", "negligence in keeping eyes forward", and "excessive handle operation". In particular, the rumble strip was analyzed and seen to be especially effective in preventing crash caused by "not keeping a safe distance," and "sleeping". The installation of the rumble strip was found to be effective in the prevention of crash caused by "not keeping the safe distance" and "sleeping". The results of this study may thus be used in deciding the causes of crash and the installation location of the tailored rumble strip that would be suitable for the geometric characteristics of the roads. This study will also be helpful in the establishment of future traffic safety measures.

Mountainous disasters such as landslides and debris flow are difficult to forecast. Debris flow in particular often flows along the valley until it reaches the road or residential area, causing casualties and huge damages. In this study, the researchers selected Seoraksan National Park area located at Inje County (Inje-gun), Gangwon Province-where many mountainous disasters occur due to localized torrential downpours-for the damage reduction and cause analysis of the area experiencing frequent mountainous disasters every year. Then, the researchers conducted the field study and constructed geospatial information data by GIS method to analyze the characteristics of the disaster-occurring area. Also, to extract more precise geographic parameters, the researchers scanned debris flow triggering area through terrestrial LiDAR and constructed 3D geographical data. LiDAR geographical data was then compared with the existing numerical map to evaluate its precision and made the comparative analysis with the geographic data before and after the disaster occurrence. In the future, it will be utilized as basic data for risk analysis of mountainous disaster or disaster reduction measures through a fine-grid topographical map.

Natural disasters can cause major accidents in chemical facilities where they can lead to the release of hazardous materials which in turn can result in fires, explosions or toxic dispersion. Technological disasters triggered by natural disasters are referred to as NaTech(Natural Disaster Triggered Technological Disaster). These trends increase the probability of catastrophic future disasters and the potential for mass human exposure to hazardous materials released during disasters. In the present study, we proposed some methods for effective disaster management by conducting case study of major NaTech. First, establishing information sharing system of chemical accident for stakeholders and improving disaster manuals and standards of central and local government and co-operation support system. Second, activating information service of emergency planning and community right to know. Third, improving the integrated chemical accident database including NaTech accidents.

Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 118~125
DOI : 10.14346/JKOSOS.2016.31.1.118
The purpose of this study is to identify issues for an effective safety culture assessment by conducting a case study of an electronics manufacturing plant in Korea. Cooper`s safety culture model was used as the assessment method, and Fleming and Hudson`s safety culture maturity models were applied as assessment criteria. The results of the safety culture assessment showed that there needs to be a design optimized for study purposes. For example, the correlation between the questionnaire survey and in-depth interview needs to be analyzed. The result of the behavior monitoring should show the relationships with other dimensions. A safety culture maturity model has to be developed to customize the study factors and questions.

Kang, Bora ; Han, Sung H. ; Jeong, Dong Yeong ; Lee, Yong-Hee ;
Journal of the Korean Society of Safety , volume 31, issue 1, 2016, Pages 126~131
DOI : 10.14346/JKOSOS.2016.31.1.126
Although many studies have been conducted to find solutions to deal with human errors effectively, violations have been rarely studied in depth. The violation is a type of human error when an employee takes an action with intention but does not intend harmful outcomes. Violations have characteristics similar to other types of human errors but it is difficult to understand the intention of an employee from accident reports. The objective of this study is to develop a conceptual model of violation errors for preventing accidents/failures in a nuclear power plant from violation errors. Based on the previous studies, the characteristics of violations were collected in 9 categories and 136 items. They were classified into three-kinds of characteristics (human-related, task-related, organization-related characteristics) to construct conceptual models of routine/situational violations. The representative cases of accidents/failures in a nuclear power plant were analyzed to derive the specific types of routine/situational violation occurrence. Three types of conceptual model for each violation were derived according to whether the basic, human-related, and task-related characteristics are included or not. The conceptual models can be utilized to develop guidelines to support employees preventing routine/situational violations and to develop supportive system in nuclear power plant.

DOI : 10.14346/JKOSOS.2016.31.1.132
The purpose of this study was to develop safety competences, a set of behavioral indicators of each competence and measuring methods of behavioral indicators for preventing human error of nuclear power plants(NPPs). The safety competences and behavioral indicators were derived from the five steps consisted of derivation of preliminary competence items through literature review, content analysis, interview(FGI, BEI), examination of content validity and decision making of final indicators. The results showed that 13 core safety competences and 35 behavior indicators were derived finally. In addition, the methods of measuring safety competences or behavioral indicators such as Behaviorally Anchored Rating Scale (BARS), Behavior Observation Scale (BOS) were developed and suggested.

Nuclear energy is considerably cheap and clean compared to other fossil fuels. Yet, there are rising safety concerns of nuclear power plants including the possibility of radiation releasing nuclear accidents. In light of the Fukushima nuclear crisis in 2011, Japan has been re-evaluating their existing energy policies and increasing the share of alternative energy. This paper first tracks the major historical changes of energy policy in Japan by time period. Next, energy security, reignited concerns and alternative energy are covered to examine Japan`s energy security situation and its transition after the Fukushima disaster. Lastly, a short survey based on thematic analysis was conducted in South Korea and Japan to understand the public awareness of nuclear. This paper postulates that the case of Fukushima will contribute to establish and operate a safe-future nuclear program in South Korea, given that the country is not only geographically neighbouring Japan but also the world`s fourth largest producer of nuclear energy.
