본 연구는 화학보호복 원단들에 대하여 내화학성 및 난연성을 조사하기 위하여 ASTM 및 ISO의 방법을 이용하여 내화학성 및 화재위험성시험을 실시하였다. 시험결과 폴리에틸렌의 경우 전혀 난연성이 없는 것으로 분석되었지만 고무에 데카브롬 등 난연성 물질이 첨가된 불소고무 원단이 뛰어난 난연성을 보였다. 특히 현재 소방용 방열복으로도 사용되고 있는 알루미늄 필름에 아라미드원단을 라미네이팅한 원단이 가장 뛰어난 난연성을 보였다. 하지만 내화학성에 있어 알루미늄은 4% NaOH에 부식되는 결과를 보이고 있어 이를 극복하기 위한 방안으로는 다층의 베리어성 필름을 사용하는 것이 좋을 것으로 사료된다. 아울러 난연성 시험결과 알루미늄필름과 폴리머 베리어성 필름을 소재로 만든 Dual skin과 불소고무에 난연성 물질이 포함된 것을 소재로 만든 Single skin이 화학보호복으로 적합한 것으로 판단된다. 또한 열방호실험과 열전달지수실험결과 두께의 증가와 다층구조일수록 TPP와 HTI 증가하는 것으로 나타났다. 향후 화학 보호복 원단의 화재위험성 및 내화학성시험 등 지속적 연구와 보완이 적절한 화학보호복 원단 성능개선에 기여할 것으로 기대된다.

본 연구는 소방훈련시 화학보호복 착용시 동작만족도를 분석하여 소방공무원의 안전을 위한 기초자료 제공을 목적으로 한다. 정적 동작만족도는 일반근무복에 비하여 화학보호복의 경우 21.7%~47.8% 정도 낮게 나타났다. 화학보호복 착용시 정적 동작자세에서는 고개 최대한 젖혀서 천장보기, 두팔 몸 앞에서 끌어안기, 비스듬히 굽혀 앉기, 과도하게 쪼그리고 앉기의 동작들이 낮게 나타났으며 통계적으로도 유의하게 낮은 결과를 보였다(p < .001). 동적 동작만족도는 일반근무복에 비하여 화학보호복의 경우 19.2%~47.8% 정도 낮게 나타났다. 화학보호복 착용시 동적 동작자세에서는 뛰기, 중량물 20 kg 허리까지 들어올리기, 중량물 20 kg 들어 1 m 옮기기, 들것 들고 앞으로 걷기, 들것 들고 뒤로 걷기의 동작들이 낮게 나타났으며 통계적으로도 유의하게 낮은 결과를 보였다(p < .001).

The purpose of this study was to investigate the actual performance of Korean firefighter's clothing through comparisons with protective clothing used in the United State, surveys of firefighter's opinion, and experiments on the material used in Korean firefighter's clothing. The paper presents experimental results as well as ways to improve current standards. The major results are as follows: 1. Korean protective clothing is too thin and too heavy. Thicker, lighter, and more heat- resistant fabric and a lighter trim should be used. 2. Korean protective clothing is not very water-resistant. A Water-resistant outershell and an innerliner which are made of air permeable and water resistant fabric must be used. 3. Korean protective clothing's outershell and innerliner should be made of fabric that is more heat-resistant, flame-resistant, and chemical resistant. 4. Protective clothing should be more brightly colored and its reflective tape should have greater reflectivity to make firefighters more visible. 5. The fastner currently used in Korean protective clothing consists of Velcro, a button, and a D-ring which can not be opened and closed quickly. A better fastener would have just velcro and a zipper. 6. The uniform for Korean firefighters consists of only a protective coat and boots. Protective trousers should be added to the standard uniform. Also, a thermal harrier should be used in winter to protect firefighters from the cold. 7. Korean firefighters should be provided with their own personal sets of protective clothing to ensure a proper fit.

Purpose: The purpose of this study was to provide basic data for the development of personal protective equipment (PPE) for emergency medical technicians (EMTs) during chemical, biological, radiological, nuclear, and explosive situations. Methods: Body measurements were obtained for adults aged from 20 to 59 years from the data in the 6 th Size Korea national sizing survey. These data were compared to the sizes of protective clothing currently available in the market. In-depth interviews with active paramedics with experiences of wearing PPE were conducted. Results: Most of the imported protective clothing turned out to be unfit for Korean adults. This showed the urgent need for developing appropriately sized protective clothing for Korean emergency technicians. In total, 55.0% of the respondents indicated that the current protective clothing is unsafe, and 71.0% requested the clothing to have level C protective performance. Regarding the design, many people wanted hooded all-in-one type of clothing. Conclusion: Considering these requirements, most of the wearers wanted their protective clothing to be fundamentally protective of their body, be available in various sizes with adjustable parts, and easy to wear and take off. They also wanted the clothing to be secure in clear sight, while not revealing any parts of their body and not interfringe with their ability to communicate with others.

This study establishes basic data for the development of a new Chemical, Biological, and Radioactive (CBR) protective clothing by selecting the ventilation position to optimize thermal comfort on the basis of the opening and closing of each part. Participants were eight men in their 20s who had previously worn CBR protective clothing. After vigorous exercise and perspiration, the microclimate of the clothing and skin temperature was measured. Results revealed that when the ventilation zipper was opened after exercising, the skin and clothing microclimate temperatures, which had increased during the exercise, decreased in the chest and shoulder blade regions. The clothing microclimate humidity decreased in the chest area. The change was greatest in the chest region; the skin temperature decreased by 0.2℃, the clothing microclimate temperature by 2.7℃, and the clothing microclimate humidity by 3.2%RH through ventilation. Thus, the opening that allows the exchange of accumulated heat and moisture while wearing the CBR protective clothing is efficient.

The selection factors of the protective clothing against the NBC agents are the protection(chemical, biological, TIMs), duration, weight/comfort, dexterity/mobility, size, visibility, cleaning and unit cost, etc. To develop the NBC protective clothing, we should need to review about the design concepts of the protective materials(shell and liner fabric) and form. This paper identify an important factors for the protective materials and form, and presents design strategies for important factors based on the evaluation results of the materials and the form.

Pursuing the fabric materials for military chemical warfare protective clothing with the improved detoxification properties, this study investigated the simple and effective cotton treatment method using pad-dry-cure process and 3-aminopropyltrimethox ysilane(APTMS) solution for surface amination. Detoxification properties of the untreated and treated cotton fabrics were evaluated via decontamination of chemical warfare agent simulant, DFP(diisopropylfluorophosphate). The surface aminated cotton fabric increased the rate of the hydrolysis of DFP by the factor of 3 and the decontamination ratio reached 88.2% after 24h. Therefore, the surface amination of the cotton fabric with APTMS can be an effective pathway to prepare the material for protective clothing against chemical warfare agents.

소방용 특수방화복의 열보호 성능 평가를 위해 대류와 복사 열원을 이용한 시험방법을 비교하였다. 특히 특수방화복을 구성하는 겉감, 중간층, 안감이 각각 열보호 성능에 미치는 영향을 대류와 복사 열원에 대해 비교하였다. 대류 열원에 대한 열보호 성능시험은 KS K ISO 9151, 복사 열원에 대한 시험은 KS K ISO 6942 그리고 대류와 복사열원을 함께 사용하는 시험은 KS K ISO 17492의 방법에 따라 수행하였다. 같은 입사 열유속 조건($80kW/m^2$)에서 시험했을 때 대류 열원에 비해 복사 열원에 대한 열전달지수($t_{12}$, $t_{24}$) 값이 보다 크게 나왔다. 이는 대류에 비해 복사에 의한 영향이 느리게 나타났음을 의미한다. 대류 열원에 대해서는 안감이 열보호 성능에 가장 크게 영향을 미쳤고 이어서 중간층, 겉감 순서였다. 그러나 복사 열원에 대해서는 안감, 겉감, 중간층 순서로 열보호 성능에 미치는 영향이 컸다. 대류와 복사는 열전달 메카니즘이 근본적으로 다르며, 열원이 달라지면 재질 구성에 따라 열보호 성능 결과가 다르게 나올 수 있다. 따라서 특수방화복의 열보호 성능을 평가하기 위해서는 대류 열원 뿐만 아니라 복사 열원에 대한 시험도 중요함을 확인하였다.

The present study developed a test protocol for evaluating the mobility of firefighting chemical and flame personal protective equipment (PPE) for the National 119 Rescue Headquarters in Korea and suggested ergonomic design factors to improve their mobility and performance. Six types of PPE were employed, including three types for flame protective PPE (5 ~ 6 kg excluding the self-contained breathing apparatus), and three types for chemical and flame protective PPE (8 ~ 11 kg). These PPEs are used by the 119 Rescue firefighters. Three male firefighters (34.3 ± 1.2 y in age, 175 ± 8 cm in height, 81 ± 13 kg in body weight) participated in the mobility test and interview. A mobility test protocol consisting of 16 components (nine postures and seven motions including a dexterity test) along with a visibility test were developed based on pre-interviews and literature reviews. The findings indicated that the clothing microclimate humidity on the neck and chest exceeded 85%RH on average for all the six PPE conditions, with the chest area reaching as high as 98%RH. This high humidity caused fogging inside the visor and impaired visibility. The requirements for improving the PPE design in terms of mobility varied depending on whether it was the separated types or all-in-one types, particularly regarding the hood and gloves design. The findings of this study can be applied to improve the design of Level A_PPE for firefighters. The mobility test protocol and visibility test developed in this study can also be applied to other types of Level A impermeable PPE.
