건축법에서 건축마감재료의 연소독성은 설치류(마우스)를 사용한 가스유해성시험으로 평가되고 있다. 최근 동물시험에 대한 최소화 및 대체시험개발의 필요성으로 인해 연소가스의 정량분석을 통한 독성지수연구가 요구되고 있다. 본 연구에서는 이미 철도차량에서 적용되고 있는 BS6853의 연소독성평가를 통해 기존 가스유해성시험결과의 상대적인 비교분석을 수행하여, 건축재료의 연소독성평가에 대한 다양한 가능성을 제시하고자 하였다.

A fire resistance certification needs to be obtained before fire protection paint can be used in Korea. In the case of paint, the tests for certification are fire, gas hazard and bond strength. According to the hazard test standard of combustion gas, 16 mice are sacrificed every test. Therefore, there are ethical problems for the experimenter and legal problems for the laboratory. Accordingly, many alternatives are being assessed, such as combustion gas analysis, but they have not replaced animal testing yet. With gas hazard testing, the exhaust gas temperature can be measured. The property of the initial reaction of a specific fire paint can be characterized by this temperature. The purpose of this study was to consider the improvement point for a gas hazard test through comparative analysis of the exhaust temperature and the time of death of the mice.

건축물 마감재료의 연소시 발생되는 독성가스는 대형화재로 인한 인명피해의 주된 원인 중의 하나이다. 현행 건축법에서는 건축물마감재료에 대하여 동물의 평균행동정지시간을 측정하는 가스유해성시험을 실시하고 있다. 본 연구는 동물시험이 아닌 NFPA 269에 의한 유효량분율(FED: Fractional effective does)을 이용하여 건축물 마감재의 독성지수를 도출하였다. 현행 가스유해성 평가 방법에서 사용되는 채임버(피검상자)를 이용하여 적외선분광분석 및 산소분석기로 연소가스를 정량 분석하였으며, NFPA269에서 규정하는 FED를 도출하였다. 몇 가지 건축재료에 대한 가스유해성시험의 평균행동정지시간과 FED의 상대적인 비교를 통해 연소가스독성평가를 수행하였다.

Casualties due to toxic smoke products have been reported as major fire damage. There are various tests in order to evaluate toxic smoke from a fire at home and abroad, and KS F 2271 as a test of the gas hazard of building finish materials has been conducted in Korea. The current test of the gas hazard exposes rodent, laboratory rat, to smoke gases to evaluate combustion gas toxicity by measuring acting time of that. this study performed a test of the gas hazard for combustible polymer material, Urethane and rubber flooring, and determined gases with the FT-IR. Quantitative results compared with standard value defined in BS6853 and toxicity index (R) was calculated. Using relative comparison with animal test and the toxicity index, We tried a variety of toxicity evaluation by correlation analysis of two tests.

This study conducted acute oral toxicity test and acute dermal toxicity test to evaluate the toxicity of lightweight and high-strength cement composite containing carbon nanotube. It was compared with the toxicity of ordinary concrete that did not contain carbon nanotube. Both lightweight and high-strength cement composite and ordinary concrete were categorized in GHS category 5 as a result of acute oral toxicity test. In addition, no toxic symproms were observed during the acute dermal toxicity test in all specimens, concluding that those were judged to correspond to GHS category 5/unclassified.

Smoke toxicity is the test for the toxicity evaluation of smoke and hazardous gas, caused by combustion of building materials and finishing materials. Smoke toxicity can be evaluated by the mean incapacitation time of mice. This test result can be influenced by the health status of mice and test condition. In acute inhalation toxicity test of hazardous gas, no typical clinical findings and histopathologic abnormalities were observed. Tracheitis and bronchitis as well as acute lung inflammation around terminal bronchiole in some mouse of the highest dose group. Through this study, we established the method for inhalation toxicity test of hazardous gas as well as the SOP of inhalation toxicity test. However, in the future studies, the concentration control methods for inhalation technologies on hazardous gas will be needed to improve continuously and also further studies on other gas inhalation toxicity will be needed to conduct.
