The purpose of this study is to analyse the hazard risk by examining the magnitude and severity of each type of hazard in order to mitigate and prepare for disasters in medical facilities. Methods: The hazard risk analysis for hazard types was surveyed for team leaders of medical facilities. The questionnaire analyzed data from 27 facilities, which were returned from 41 Local Medical Centers. Results: When looking at the 'Risk' by category type of hazard, the influence of health safety and fire/energy safety comes first, followed by natural disaster, facility safety, and crime safety. On the other hand, as for 'Magnitude', facility safety and crime safety come first, followed by health safety, fire/energy safety, and natural disasters. Most of the top types of disaster judged to have high hazard in medical facilities are health types. The top five priorities of hazard in medical facilities, they are affected by the geographical and industrial conditions of the treatment area. In the case of cities, the hazard was found to be high in the order of infectious disease, patient surge, and wind and flood damage. On the other hand, in rural areas, livestock diseases and infectious diseases showed the highest hazard. In the case of forest areas, the hazard was high in the order of wildfire, fire accident, lightning, tide, earthquake, and landslide, whereas in coastal areas of industrial complexes, the hazard was high due to fire, landslide, water pollution, marine pollution, and chemical spill accident. Implications: Through the research, standards will be established for the design of hospitals with disaster preparedness, and will contribute to the preparation of preemptive measures in terms of maintenance.

Objectives: This study was performed to check whether the CRS (Chemical Ranking and Scoring) system is appropriate as a method to determine substances as candidates for substances subject to permission and to apply this system to the selection of candidates for substances subject to permission. Methods: A risk score was obtained by multiplying the hazard score and the exposure score and then ranking them. The hazard sub-indicators are carcinogenicity, germ cell mutagenicity, reproductive toxicity, specific target organ toxicity-repeated exposure, respiratory sensitization and endocrine disrupting chemicals. Exposure sub-indicators are persistence, bioaccumulation and emission volume. Sensitivity analysis was performed for missing values. Correlation analysis and multivariable linear regression analysis were performed among hazard, exposure and risk in order to confirm that CRS was an appropriate method. Results: As a result of the sensitivity analysis on missing values, it was confirmed that the effect on the risk ranking was not sensitive. Correlation and regression analysis confirmed that exposure had a greater effect on risk than hazard. Conclusions: The CRS system, which derives a risk score using a hazard and exposure score, is judged to be appropriate as a method for the selection of preliminary of candidates for substances subject to permission. Benzene, cadmium, nickel, and cobalt were selected as priority candidates for substances subject to permission.

유탕면류의 HACCP(Hazard Analysis Critical Control Point) 시스템 구축을 위하여 유탕 공정-CCP(Critical Control Point)에 대한 미생물학적(Biological hazards)과 화학적(Chemical hazards) 한계 기준 설정을 위한 목적으로 수행하였으며, 경기도 이천 소재의 P사에서 실행하였다. 유탕공정은 각각의 시간과 온도 측정에 따라 미생물학적, 화학적 위해요소를 제거하거나 감소에 대해 실험하였다. 실험결과 Standard plate count와 식중독균은 유탕공정(Temperature : $145{\pm}10^{\circ}C$, Time : $75{\pm}30$ sec)에 의해 검출되지 않았다. 유탕공정에 의해 생성되는 화학적 위해 기준의 산가는 법적 기준치인 0.6보다 낮은 0.2 이하였다. 증숙실과 유탕실의 공중낙하균을 측정한 결과 3 CFU/mL, 3 CFU/mL 검출되었다. 따라서 유탕공정의 CCP-BC는 일반세균과 식중독균, 산화생성물 생성을 예방, 제거하는데 좋은 대안책이 될 것이다. 결론적으로 HACCP을 위해 유탕공정에 대한 한계기준설정, 모니터링방법, 개선조치, 검증방법, 교육, 기록관리가 필요하다고 생각된다.

최근 화학공장의 중대산업사고로 인한 인명피해가 발생하면서 화학공장의 안전성에 대한 불신이 높아지고 있다. 또한 한정된 자원과 공간 속에서 생산량의 증가와 원단위의 감소를 위해 설비는 점점 고도화와 대형화되는 추세임으로 이러한 중대산업사고의 위험성은 높아질 수 밖에 없다. 이러한 상황속에 장외영향평가 도입으로 정량적위험성평가가 활성화되면서 화학공장에 대한 객관적인 위험성을 평가할 수 있는 초석을 마련하였다. 하지만 현재 장외영향평가는 화재/폭발/누출에 대한 영향범위가 사업장 밖까지 도달하는지를 평가하는데 중점을 두고 있다. 이런 경우 중대산업사고가 인근지역에 미치는 영향은 분석할 수 있지만 사고발생빈도와 사업장 주변 인구밀도에 따른 실제 위험성을 평가하기는 어려울 수 있다. 이 연구에서는 중대산업사고에 대해 끝점만 분석하는 경우와 F-N curve를 적용하는 경우를 비교하는 사례연구를 통해 장외영향평가 F-N curve를 적용하는 것에 대한 타당성을 분석하였다.

The risk assessment of thermal hazard to identify chemical or process hazard during early process developments have been considered. The early identification of thermal hazards associated with a process, such as rapid heats of reaction, exothermic decompositions, and the potential for thermal runaways before any large scale operations are undertaken. This paper presents to evaluate the safe operating parameters/envelope for exist plant operations. The assessment of thermal hazard with operating conditions such as amount of process materials, inhibitor, and catalyst on esterification process in manufacture of concrete mixture agents are described. The experiments were performed by a sort of calorimetry with the Multimax reactor system as a screening tool. The aim of the study was to evaluate the thermal risk of process material and mixture in terms of safety security to be practical applications in esterification process. It suggested that we should provide the thermal hazard of reaction materials to present safe operating conditions with cause of accident through this study.

The construction industry is demanding, dynamic, and complex making it difficult for workers to recognize hazards. The nature of construction tasks exposes workers to several critical risk factors, such as a high rate of exertion and fatigue. Recent studies suggest that fatigue may impact hazard recognition in the construction industry. However, most studies rely on subjective measures when assessing the relationship between physical fatigue and hazard recognition, limiting such studies' efficacy. Thus, this study examined the relationship between physical fatigue and hazard recognition using a controlled experiment. Worker fatigue levels were captured using physiological data and a subjective exertion scale. The findings confirmed that physical exertion plays a significant role in hazard recognition skills (p < 0.05). This research contributes to theory and practice by providing a process for objectively assessing the influence of physical fatigue on worker safety and providing construction professionals with some critical insight needed to improve workplace safety.

As the preliminary data collection for further chemical risk assessment. toxicants rating works is now rather extensively implemented in China. It consists of two parts, ie., rating of the hazard level of the exposed toxicant and that of the toxicant's profession. In the first part, the rating are based on six criteria, ie., acute toxicity, incidence of acute poisoning, prevalence of chronic poisoning, consequence of chronic poisoning, carcinogenecity and MAC level. Four hazardous levels are to be classified as extreme, high, medium, mild. In the second part. three determinants as weighted coefficients are taken into account, ie., toxicant's hazard level. exposure time and folds of MAC surpassing. Eventually, the index of classification C by which the work with toxic hazard can be classified is able to be calculated and assessed. Several comments were discussed and new recommendations were demonstrated.
