Objectives: In this study, we analyzed the current state of delivery containers and packages and established handling guidelines to safely transport delivery containers and packages for use in research, testing, and examination reagents. Methods: Handling guidelines were revised in such categories as maintenance of the handling facilities, storage, loading and unloading, containers and packages, transportation, etc. In addition, we analyzed the current state of domestic sales for hazardous chemicals used for research, testing, and examination reagents, and investigated the handling guidelines related to delivery transportation in the USA, EU, and Japan by chemical property. Results: There are 6,160 companies selling hazardous chemicals. Among them, the 476 companies selling reagents for use in research, testing, and examination were investigated. Total amounts handled reached 425,000 tons, contributing to 0.2% of the total. For delivery transportation, internal containers and packaging was specified for chemical properties as follows: within 1 L for flammable gas, within 5 L for flammable liquid, and within 18 L for others. In addition, the maximum size of the outer package was set within 130 cm for total length, width, and height, and no dimension of the packaging could exceed 60 cm. Sixty-four hazardous chemicals with explosiveness or acute inhalation toxicity were prohibited for delivery transportation. Conclusion: Specified handling guidelines for inner and outer containers as well as packaging were regulated for delivery transportation of hazardous chemicals used for reagents. In addition, 64 hazardous chemicals were prohibited for delivery transportation. These are designed to prevent transportation accidents involving hazardous chemicals for reagents and thus protect the safety and health of transporters who handle hazardous chemicals.

Two experiment are planed to identify driver's safe driving behaviour by curve radius, road surface condition in curve section. At four-lane and two-lane road, conducted experiments are check on driver's feeling of safety that 30 subjects do not feel discomfort. And using the data from these experiments, this study compare physical speed (not slipping, fall our of the road) with safety driving speed(drivers felt a comfortable and safe speed) each curve radius and fiver road surface condition(drying, wet, rain, snow and ice). As a result, safe driving behaviour factors that are derived to curve radius of 100m units, five road surface conditions enable to represent quantitative analysis of driver's discomfort. This study will develop road design method and evaluation reflected ergonomic aspects.

Current risk assessment of Spent Nuclear Fuel (SNF) transportation has the problem of the incomplete risk factors consideration and the general particle diffusion model utilization. In this paper, the accident frequency calculation and the detailed simulation of the accident consequences are coupled by the integrated risk assessment method. The "man-machine-environment" three-dimensional comprehensive risk indicator system is established and quantified to characterize the frequency of the transportation accidents. Consideration of vegetation, building and turbulence effect, the standard k-ε model is updated to simulate radioactive consequence of leakage accidents under complex terrain. The developed method is applied to assess the risk of the leakage accident in the scene of the typical domestic SNF Road Transportation (SNFRT). The critical risk factors and their impacts on the dispersion of the radionuclide are obtained.

Railway is one of popular transportation systems. Due to the safety and in time, the transportation by train is preferred to the others for a long time. However, accidents under railway construction get more serious problems than in case of the other system, because it is the largest mass transportation system. Especially, the railway construction is composed of different kinds of construction works such as civil, architect, electric and mechanic. It is closely/complicatedly connected with various workers, large machines and facilities, regulations etc. In this study the data on safety accidents are corrected during 6 years(2004~2009) and analyzed by time(year, month, week, day, a.m or p.m), place, field, type etc. Results shows that there exists remakable trends on accidents, so efficient treatments should be prepared considering this trend.

This report presents guidelines for the systematic management of packaging, storage, transportation, and traceability of source cells used for organoid research. Given the important role of source cells in organoid studies, it is important to ensure the preservation of their quality and integrity throughout transportation and distribution processes. The proposed guidelines, therefore, call for a cohesive strategy through these stages to minimize the risks of contamination, deterioration, and loss-threats that significantly compromise the safety, efficacy, and efficiency of source cells. Central to these guidelines is the quality control measures that include roles and responsibilities across the entire supply chain, with recommendations specific to packaging materials, transportation facilities, and storage management. Furthermore, the need for an integrated management system is emphasized, spanning from source cell collection to the final application. This system is crucial for maintaining the traceability and accountability of source cells, facilitating the sharing, distribution, and utilization on a global scale, and supporting to advance organoid research and development.

This study investigated the probability of possible accident through qualitative and quantitative analysis of the pressure safety valve types installed in facilities using high pressure gas to compare the installation domestic and foreign pressure safety valve standards sought the safety characteristics and safety improvement direction accordingly. The three types are the case where the shut-off valve is not installed at the front of the PSV (Case A), If a shut-off valve is installed at the front of the PSV for inspection (Case B) and If a shut-off valve is installed in front of PSV (C.S.O), PSV is installed in parallel (Case C). Three types of cases were compared with FTA and HAZOP. The results of study of the possible accidents due to over-pressure safety valve installation type, used in a high-pressure gas facilities was shows in the following order Case B > Case A > Case C. The results of analysis through FTA was in order to protect the reservoir for the possible occurring of accident the safety valve installation is depend on its type. In the FTA analysis, defects in the device itself which attached to the storage tank as a substitute for analysis of the probability of operator mistakes was Case B with as high as $2.01{\times}10^{-6}$. Depending on the type of installation analysis of Case B in order to ensure safety is prohibited to install shut-off valve and believes that mandatory regulations are needed. Rationally installing of pressure safety valve in the high pressure using facilities will be expected to improve the industrial safety from severe accidents such as high-pressure gas fire explosion.

The objective of this paper is to calculate the minimum scale of management for transportation business in order to achieve a form of enterprise. In this study the tracking minimum scale of business is the minimum number of operating trucks. Transportation companies should ensure the number of trucks for a type of business model rather than a means of livelihood model. The method to calculate the minimum number of trucks for the transportation business model can use an approach of either the qualitative and the quantitative technique. This study chooses the quantitative technique to calculate the minimum number of trucks through the analysis of break-even point.

Radiopharmaceuticals that need to be transported in a low-temperature state must satisfy both radiation safety and proper temperature maintenance. However, an efficient transport system considering the characteristics of radiopharmaceuticals that require low temperature maintenance has not yet existed. In order to secure a transportation system for the safe and stable transportation of the radiopharmaceutical ¹³¹I mIBG, which requires transportation in cryogenic conditions, we have developed a transportation system that can maintain cryogenic conditions below -60℃ for 6 days while stably fixing the inner container. In addition, by applying a data logger that can simultaneously measure the temperature and the dose of radiation, safety and stability in the transportation process can be secured at the same time. The cryogenic transportation system for ¹³¹I mIBG will be applied to products currently being supplied, and we expect to dramatically improve the management of cold chain radioactive material transportation.

Occupational Safety and Health Expenses Law in construction industry was enacted in 1988 by the notification of Ministry of Employment and Labor and 22 revisions have been made since. The fact that revisions have been made almost every year since the first enactment shows that Occupational Safety and Health Expenses can effectively prevent construction accidents and the need for revisions to fit the reality has been raised continuously. Despite the construction industry has undergone various internal and external environmental changes, (such as the changes in the safety and health management techniques and the increase in the construction employees' desire for safety) the appropriation standard of Occupational Safety and Health Expenses has been calculated based on the contract price. The construction industry has constantly suggested that the Occupational Safety and Health Expenses be calculated based on the estimated construction expenses since applying the current method doesn't provide enough money to secure the safety. Also because it has become mandatory to hire a health manager since 2015, the lack of Occupational Safety and Health Expenses is expected to get worse. In this study, we will analyze the usage of Occupational Safety and Health Expenses and propose a more practical and realistic change in setting the appropriation standard of Occupational Safety and Health Expenses.
