  • This study aims to provide a methodological framework to estimate the travel demand of hazardous materials transporting vehicles by link and analyze daily traffic patterns on an expressway to develop safety roadway management strategies. Traffic volume of hazardous material vehicles is counted through the on-site investigation at twenty-five tollgates on the expressway, and their demands by a link are predicted through origin-destination flows estimation. The result shows that the number of the domestic hazardous materials vehicles is approximately 51,207 vehicles per day and it indicates that hazardous materials transport vehicles account for 1.5% of total daily traffic on the internal expressway and 6.2% of total cargo traffic volumes. This study roughly estimated how many hazardous materials vehicles pass through the expressway segment. Thus it is expected to be utilized for establishing a systematic highway management strategy in the future by calculating the traffic volume of the hazardous material vehicles traveling on the interstate expressway.

  • The systems in Korea regarding manufacture, storage, transport and use of hazardous materials are regulated by the related laws and ordinances. The number of accident from hazardous materials has recently decreased but the size of accident has increased according to the hazardous substances are greatly consumed and delivered. The results of analysis showed that most of accidents are caused by human problems and occurred frequently at unauthorized facilities. It is suggested that workers should be trained more and the strict regulation on unauthorized facilities is needed to reduce the accidents caused by hazardous materials.

  • 본 연구의 목적은 현행 위험물안전관리법이 위험물에 대한 저장, 취급 및 운반 등에 대한 예방정보전달(information communication)의 주요내용으로만 구성되어 있으므로 사고대응(incident response)에 대한 내용이 아주 미미함으로 초기대응에 문제점이 도출되고 있는 실정이다. 따라서 사고예방과 대응을 동시에 갖는 선진화 방법인 GHS체계로 위험물안전관리법 개선(안)을 제시하고자 한다. 또한 위험물안전관리법과 GHS제도의 위험성 분류체계가 많이 달라 제조소 등의 산업계와 수 출입 업체에 혼란을 야기 시킬 수 있으므로, 주요 선진국의 위험물 분류체계 분석을 통하여 위험물안전관리법과 GHS 분류체계의 조화방안을 제시하였다.

  • 위험물들은 위험물의 사용, 저장 및 관리뿐만 아니라 수송시에도 많은 위험성을 내포하고 있어 많은 나라에서는 적당한 기준을 마련하여 특별히 관리하고 있다. 우리나라 철도 위험물 안전수송에 관한 철도안전법 개정을 위하여 국내 철도 위험물의 수송량과 종류를 분석하고 국내외 위험물분류기준을 비교하였다. 우리나라는 지리적으로 대륙을 연결하기 편리한 위치에 있어 향후 국경을 넘어 대륙을 횡단하는 국제법을 채택하는 것이 매우 유리하고, 수송되어야 할 물질의 종류가 다양해질 것을 대비하여 국제적으로 통용될 수 있는 위험물분류와 위험물판정방법을 채택하는 것을 제안하였다.

  • The content of hazardous heavy metal of materials used in playground facility for children was investigated using X-ray fluorescence (XRF) and inductively coupled plasma (ICP) analyses, In order to examine the content of hazardous heavy metals according to the material color, four colors, i.e., green, red, yellow and blue, were categorized on the materials used. The highest lead content is observed in the yellow plastic samples. The yellow samples with relatively high lead content show that the chrome content is also high. This can explained that lead chromate, so-called chromium yellow, is normally used as a main pigment to express the yellow color. Therefore, it is concluded that hazardous heavy metal detected in the materials of playground facility for children is due to the pigments used for coloring. Based on above findings, the relationship between the color of materials used in playground facility for children and the content of hazardous heavy metal is discussed.

  • Feed safety is needed to produce and provide safe animal feeds for consumers, animals, and the environment. Although feed safety regulations have been set for each country, there is a lack of clear feed safety regulations for each livestock. Feed safety regulations are mainly focused on heavy metals, mycotoxins, and pesticides. Each country has different safe levels of hazardous materials in diets. Safe levels of hazardous materials in diets are mostly set for mixed diets of general livestock. Although there is a difference in the metabolism of toxic materials among animals, the safe level of feed is not specific for individual animals. Therefore, standardized animal testing methods and toxicity studies for each animal are needed to determine the correct safe and toxic levels of hazardous materials in diets. If this goal is achieved, it will be possible to improve livestock productivity, health, and product safety by establishing appropriate feed safety regulations. It will also provide an opportunity to secure consumer confidence in feed and livestock products. Therefore, it is necessary to establish a scientific feed safety evaluation system suitable for each country's environment. The chance of outbreaks of new hazardous materials is increasing. Thus, to set up appropriate toxic levels or safe levels in feed, various toxicity methods have been used to determine toxic levels of hazardous materials for humans and animals. Appropriate toxic testing methods should be developed and used to accurately set up and identify toxicity and safe levels in food and feed.

  • The purpose of this study is to suggest improvement plans for prevention regulations by reflecting the toxicity, fire and explosion effects of hazardous materials factories and surrounding areas using an off-site consequence assessment program. Regarding the effects of the hydrogen cyanide leak accident, which is the 1st petroleum of the 4th class flammable liquid, Areal Locations of Hazardous Atmospheres (ALOHA) program was used to compare and analyze the extent of damage effects for toxicity, overpressure, and radiation. As a result, the toxicity was analyzed to exceed 5km in the area with Acute exposure guideline level (AEGL)-2 concentration or higher, the overpressure was 103m in the range of 1 psi or more, and the radiant heat was analyzed to be 724m in the range of 2kw/m2 or more. Toxicity and radiation affected the area outside the hazardous material storage area, but the overpressure was limited to the inside of the hazardous material storage area. Therefore, we propose to improve the safety management of hazardous materials by conducting a risk assessment for hazardous materials and reflecting the results in internal and external emergency response plans to prepare prevention regulations.

  • 국내 전국대학 실험실을 비롯한 위험물 관련 사고사례를 조사하였으며, 중앙소방학교를 비롯한 서울, 경기, 부산, 광주, 경북, 충청소방학교의 위험물에 대한 교과운영이 어떻게 이루어지고 있는지 조사하고, 각 대학 소방관련학과에서 운영하고 있는 위험물질론 교과운영이 어떻게 진행되고 있는지에 대해서도 조사하였다. 또한 중앙 119 구조대를 비롯한 각 지방소방학교에서 교육을 받고 있는 현직 소방공무원을 대상으로 위험물관련 교육에 대한 설문조사를 실시하였다. 설문분석결과, 위험물 관련실험 교육과정 및 실험매뉴얼의 개발이 시급한 것으로 조사되었고, 지방소방학교의 위험물관련 교육은 전공자가 강의를 해야 하고, 위험물관련 사고예방을 위한 전문가 교육이 필요한 것으로 조사되었다. 따라서 실험중심의 위험물 교과운영으로의 개선이 필요한 것으로 분석되었다.

  • It is very important to classify explosion hazardous area in order to prevent an accident explosion. In order to prevent such a explosion, the Industrial Safety and Health Standards Rules stipulates the establishment and management of explosion hazards in accordance with the criteria set by the Korean Industrial Standards. This study has investigated the range of the explosion hazardous area according to various hole sizes, pressures, vapor densities, and wind velocities in the outdoor flammable liquid tank using KS C IEC-60079-10-1 $2^{nd}$ Ed.(=IEC CODE) and PHAST. The results show that the explosion hazardous areas by IEC CODE have circle shapes. However, the areas by PHAST show ellipse shapes. The different of the explosion hazardous areas increases with the increase of wind velocity.
