화학관련분야의 공정안전에 관하여 오랜 역사를 가진 AIChE는 관련산업분야의 안전규정을 예방적인 측면과 사고원인을 규명하기 위한 측면에서 근원적인 자료를 제시하였고 1955년 AIChE에 의해 설립된 CCPS(center for chemical process safety)는 이에 관한 기술적인 면에 더욱 발달된 정보를 제공하게 되었다. 이런 정보들 가운데 사업장의 위험물질이 지니고 있는 위험성을 어떻게 평가할 것인가에 관하여 CPQRA(chemical process quantitative risk analysis)방법이 제시되어 있다. 1) CPQRA는 양적인 의미에서 위험성의 정의, 분석, 평가, 통제 및 관리방법 등에 대비해 잠재적인 방법을 제시한 것이다.

To establish the necessary safety technology in high-pressure toxic gas facilities, especially for the corrosion, which is the main causes of toxic gas accident, this study adopts and investigates the API-581 procedures developed by the American Petroleum Institute (API). And the applicability of the 8-step analytical procedures of consequence analysis in API-581 is discussed, and a method for consequence analysis in high-pressure toxic gas facilities is suggested. Based on the discussion and results, the analytical procedure is simplified as the 6 steps in total for the effective application to high-pressure toxic gas facilities: Step 1 (determination of representative material), Step 5 (determination of release type), Step 6 (determination of phase of fluid), and Step 8 (estimation of damage range) are not applied: Step 3 (estimation of total amount of release) is applied only for the inventory group concept; Step 4 (estimation of release rate) only for the gas release rate; and all of Step 2 (selection of release hole size) and Step 7 (evaluation of post-release response) are applied. In the proposed method, the generally applicable method of CCPS is adopted as alternative method for Steps 5 and 8.
