본 연구에서는 천연계면활성제 조성물의 친환경적인 포소화약제를 개발하였으며, 소화성능과 환경친화성을 검증하기 위한 방법으로 한국소방검정공사에서 제시하는 "수동식소화기의형식승인및검정기술기준"에 의한 A2단위 소화능력시험과 안전성평가연구소(한국화학시험연구원)에서 제시하는 육생식물생장실험 및 어류급성독성실험을 수행하였다. 그 결과, 소화성능은 A급 일반화재 5단위, 육생식물생장실험에서 발아에 대한 $LC_{50}$은 75(g/kg), 생장에 대한 $EC_{50}$은 62(g/kg), 어류급성독성실험에서 6658 ppm의 결과를 보여, 현재 국내에서 상용화되어 있는 타 약제보다 월등한 것으로 나타났다. 또한 약제로써의 활용을 위한 기본 물성치 및 내부식성에서도 기준에 적합한 결과를 나타내었다.
In this research, an environmental-friendly foam extinguisher was newly developed using a natural surfactant as its composition. Two criteria were applied to verify its extinguishing performance and environmental attraction. One is unit 2 model by "Standards of Model Approval and Inspection Technology for Portable Fire Extinguishers" presented in Korea Fire Equipment Inspection Corporation. The other is Terrestrial Plants, Growth Test and Fish, Acute Toxicity Test presented in Korea Institute of Toxicology(Korea Research Institute of Chemical Technology). Test results showed that the extinguishing performance was 5 unit of general fire Class A, the $LC_{50}$ by germination was 75(g/kg) and the $EC_{50}$ by growth was 62(g/kg) through Terrestrial Plants, Growth Test, and also the toxicity was 6658 ppm in Fish, Acute Toxicity Test. The numerical values were highly evaluated than other fire extinguishing agents being commercialized in domestic. The results also showed suitably in basic physical properties and anti-corrosion properties for making use of fire extinguishing agent.
Key Words: Foam extinguisher, Natural surfactant, Extinguishing performance, Toxicity, Fire extinguishing agent
