Abstract

Hydrofluoric acid is a less acidic substance than hydrochloric acid, nitric acid, and sulfuric acid, but it is one of the most dangerous substances for humans. In recent years, it has become an indispensable substance in industries such as chemical plants and the semiconductor industry, and although it is a threat to the human body, its use is increasing for various purposes, and the amount of use is constantly increasing due to the expansion and development of the industry. The dangers of hydrogen fluoride have been highlighted since the 2012 accident, which led to a more than fivefold increase in management standards for handling facilities. Hydrogen fluoride converts to hydrofluoric acid when exposed to the air, which can be fatal to humans. This study simulates the effects of a release of a toxic substance in the workplace, even though a protection layer has been provided to minimize the damage caused by the released toxic substance, and recommend ways to control the risk to workers in the event of a release in the workplace.

불화수소는 염산, 질산, 황산보다 산성도는 낮지만 인체에 위험한 물질 중 하나이다. 물질의 구성에서 볼 수 있듯이 Fluoride를 함유하고 있는 부식성이 강한 물질이며, 급성독성 물질로 분류할 만큼 인체에 유해성이 매우 높으나, 최근 화학공장 및 반도체 산업 등 산업계에서 없어서는 안 될 물질로 인체에 위협적인 물질이지만 산업의 확장과 발전으로 사용량이 지속적으로 증가하고 있다. 불화수소의 위험성은 2012년 사고 발생 이후 위험성이 대두 되었고 이 사고를 계기로 규제 강화로 취급시설 관리 기준이 5배 이상 늘어나게 된 원인되었다. 불화수소는 대기 중으로 노출되는 경우 불산으로 전환되며 인체에 치명적인 영향을 미칠 수 있다. 본 연구는 독성물질 누출에 의한 피해를 최소화하기 위해 방호계층을 구성하였음에도 누출된 독성물질이 사업장 내로 확산되었을 때 피해영향을 시뮬레이션으로 확인하고, 사업장 내 피해영향 시 근로자에게 발생하게 될 위험성을 제어하기 위한 방법을 제언하고자 한다.
