  • Mixed acid is very reactive and highly corrosive. it has been causing many accidents in a electronic industry, a steel industry, and a chemical industry. Therefore, it is required that the high safety level for the acid storage facilities. In this study, we investigated the accident causes for resent leak accidents with Root Cause Analysis (RCA). The root causes analysed by RCA were categorized as nine divisions by the their characteristics. Furthermore, each nine divisions causes was applied to the PDCA model which are using at OHSAS 18001. It is suggested that the nine division with the root causes can be the essential items for the development of the safety management manual. It is helpful to the safety improvement of the acid storage facility.

  • In this paper, efficiency estimation of toxicity fee fire resistance cable experiments was measured smoke density of toxicity free fire resistance polyolefin insulation material and electric field dependence of tree shape in low density polyethylene (LDPE). One of the most serious causes of failure in high-voltage cables, can be an electrical discharge across an internal gab or void in the insulating material. Treeing due to partial discharge is one of the main causes of breakdown in the insulating materials and reduction of the insulation life. Therefore the necessity for establishing a method to diagnose the aging of insulation materials and to predict the breakdown of insulation and research of the fire resistance character has become important. First, we have studied on electric field dependence of tree shape in LDPE about treeing phenomena occurring on the high electrical field. Second, the measurement method is the attenuation quantity of irradiation by smoke accumulating with in a closed chamber due to non-flaming heat decomposition and flaming combustion. A main cause of fire-growth and generating toxic gas when, it bums, should be dealt with great care in life. safety design. The fire gases were occurred carbon monoxide and decomposition than in polyolefin due to incomplete combustion of PVC, which has high content of carbon in chemical compound.

  • ${\ulcorner}Volume\;1{\lrcorner}$ of ${\ulcorner}$Medical Records as a Guide to Clinical Works${\lrcorner}$, written by Ye Tian Shi, showed some clinical cases of dizziness. In this study, his diagnosis and treatment was studied with 16 clinical cases of dizziness with pathogenic factor, pathogenesis and symptoms of dizziness. Ye Tian Shi thought that phlegm, fire, wind and insufficiency were the causes of dizziness and phlegm-fire, phlegm-fire-wind, wind-phlegm and insufficiencyfire-wind were the causes of dizziness, clinically. Dizziness is caused when the body is in condition of excess in the upper and deciency in the lower. The acompanying clinical symptoms of dizziness are endogenous wind, fire of deficiency type, phlegm wind and phelegm fire. For the treatment of dizziness, Ye Tian Shi used the combination of medicines with some modifications by the cases for phlegm, fire, wind and insufficiency. He also encouraged the mental therapy for the treatment of dizziness. He emphasized the early treatment of dizziness to prevent hemiplegia after apoplexy. It can be postulated from Volume 1 of ${\ulcorner}$Medical Records as a Guide to Clinical Works${\lrcorner}$, diagnosis and treatment of symptoms and illness of Ye Tian Shi was strictly based on actual clinical cases.

  • The victims of fire are increasing steadily. Fires have been occurred by arson, spontaneous combustion and various causes. As a result of that, the damages of fire got out of hand. Especially, the fires of flammable liquids are can be spreaded easily because of high calorific value and fire loads. These rapid fire spread cause the huge losses of both life and property and the malfunction of extinguishing systems. In these studies, we examined the spread pattern of surface fire on the water surface by the reappearance experiment.

  • The purpose of this study is to analyze four cases of firefighter burns in various fire scenes and to find prevention measures to decrease firefighter injuries. Among the analysis reports prepared by the National Fire Research Institute of Korea from 2016 to 2020, four burn-related accidents are summarized and the main causes are conveyed. The four accidents include second-degree burns from using extinguishers during containment of fires; nine firefighters burned due to re-ignition in the LPG car repair shop; two firefighters injured with third-degree burns from using fire extinguishers during life-saving events in residential housing; and injuries from the radiant heat of the tank BLEVE near the factory fire. These cases are comprehensively investigated in their respective scenes and analyzed based on the fire site investigation reports from the fire department and related theoretical explanations of risk for each accident scene. In the third case study, some experimental research is conducted to evaluate the risk involved with the use of safety gloves. This is evaluated by reviewing Fire Tactics and Standard Operational Procedures (SOP) to determine improvements and recommendations for an efficient firefighting response. Results show that the main causes of burn accidents are the insufficient use of personal protective equipment (PPE), such as safety gloves, and the failure to follow firefighting tactics or SOPs. Through the accident investigation and assessment, it is concluded that to reduce the frequency of burn accidents, the performance of firefighting equipment, SOPs, protection tactics, and safety policy systems require improvement.

  • 이 논문에서는 1회용 가스라이터의 규제실태, 화재발생 실태, 화재 및 사고의 발생원인, 예방대책을 조사 분석하였다. 1회용 가스라이터에 어린이 보호기능이 의무화된 이후에는 미국과 일본 등과 마찬가지로 전체화재 중 불장난으로 인한 화재의 비율이 감소하고 있다. 1회용 가스라이터로 인한 화재는 방화와 불장난을 제외하면 잔화, 의도하지 않은 점화, 큰 화염 발생, 고온장소 방치로 인한 파열 또는 폭발 등에 의해 발생하고 있다. 예방대책은 어린이 불장난 도구로 이용될 수 없게 조치, 잔화로 인한 화재사례 홍보, 차량 대시보드 위 또는 고온장소 방치의 위험성 홍보, 차량 의자 레일 멈춤 부분의 보호용 합성수지 커버의 개선, 서랍 등에 보관 시 주의사항 홍보, 폐기방법 홍보 등을 제안한다.

  • 화재현장은 바람의 방향과 세기, 가연물의 조건, 건물의 형태 등에 따라 다양하게 소훼형태가 변하기 때문에 발화부와 화재원인을 판단함에 있어 세심한 주의가 필요하다. 본 연구에서는 화재 조사자들이 곤란을 겪고 있는 환기지배와 연료지배에 따른 연소형태, 인화성물질에 의한 바닥재의 탄화형태와 낙화(落火)물에 의한 연소흔적을 사례를 통해 살펴보고 조사방법을 제시하였다.

  • Most truck fires breaking out on the expressway are directly damaged by fire destruction of truck and freight and many of them cause indirect damage such as serious traffic holdups. This study analyzed the fire causes and their liability of the 25-ton truck fire breaking out during expressway driving. This truck fire was caused by manufacturing defect of return spring of a braking system. The fire liability rested with a maker(manufacturer) rather than a truck owner or a driver and the maker also bore fire liability based on the Product Liability Law.

  • Many of our contemporaries suffer from the symptoms of phlegm-fire, which is caused by stress, processed food, heavy diet, and unseasonal fruits and vegetables. With consultations from 'Euihaklpmoon', 'DongeuiBogham', and 'Ji-San's clinical lectures' this research, which is mainly focused on phlegm-fire, concluded as following. Phlegm-fire is caused by congestion of seven emotions, congestion of qi, complication of phlegm on fire, depletion of body fluids after long periods of disease, heavy diet, or congenital unbalance of yin-yang and qi-hyul. Concentration of phlegm-fire on the head causes headache, dizziness, frontal headache, tinnitus, and auditory dysfunction. The patient usually complains breaking pain. Dhamhwabang of Yijin-tang, Chunghoonhwadham-tang, and Yijin-tang variation for right headache can be used. Concentration of phlegm-fire on the thorax causes insomnia, palpitation, and insanity. Samhoohndham-tang variation, Chungsimgondhanhwan can be used. Concentration of phlegm-fire on the gastric region causes reflux of gastric acid, eructation, vomiting, abdominal discomfort, dysmenorrhea, and fluor gentalis. Yijin-tang variation for abdominal discomfort, Yanghyulsamul-tang, Hwadhamchunghwa-tang can be used. Shin type or Gi type, female with prevalence of qi and tendency of fire, female with dark facial color, female with raised eye tails and large noses, female with pointed noses, and male or female with large noses and mouths are likely to possess phlegm-fire. Abdominal discomfort of male with thick eyebrow and headache of Gi type female is usually caused by phlegm-fire.
