Abstract

Purpose: Ministry of Environment statistics reveals more than 132 fire·explosion accidents in South Korea between 2014 and 2023. Among them, fire and/or explosion accidents are very impactive in their scale and consequence. This study aims to suggest a new method of reasonable way to calculate the ventilation rate of indoor facility handling hazardous chemicals based on their inflammability. Method: A new method to calculate the ventilation rate is based on the physicochemical properties of the chemicals handled, which is more reasonable compared with the current regulation based only on the floor area of the facility. Result: Considering the physicochemical properties, 178 chemicals based on their inflammability were studied and 168(94%) met the criteria for the current regulation. Some materials have been shown to require too much or too little ventilation rate. Conclusion: Through this study, a reasonable method of calculating the required ventilation rate was proposed. This should be applied to ensure the safety of workers to deal chemicals.

연구목적: 환경부 통계에 의하면 2014년부터 2023년까지 국내 화재·폭발사고가 132건 이상에 이르는 것을 알 수 있다. 이중 화재·폭발사고는 발생 시 규모나 영향이 상대적으로 매우 커서 주의가 필요하다. 본 연구에서는 인화성의 유해화학물질 취급 시 실내 취급시설의 적정 환기율을 계산하는 새로운 합리적인 방법을 제안하였다. 연구방법: 취급시설의 바닥면적만을 기준으로 한 현행 화학물질관리법 상 계산방법과 비교하여 보다 합리적인 새로운 방법은 취급하는 유해화학물질의 물리화학적인 특성을 기반으로 계산하는 방법이다. 연구결과: 물리화학적 특성을 고려하여 계산한 결과 인화성물질 178종 중 168종인 약 94%이 환기량 기준에 적합하였다. 그러나 일부 물질은 과소환기 및 과대환기를 요구하는 것으로 나타났다. 결론: 본 연구를 통해 합리적인 필요환기량 산정방법을 제안하였고 이를 통해 근로자의 안전을 확보하고 생명을 보호해야 할 것이다.
