범용 고분자 제조공정의 재해분포 특성

Characteristics of Accidents Distribution in General Polymers Manufacturing Processes

Abstract

산업현장에서는 폴리에틸렌(PE), 폴리프로필렌(PP), 폴리염화비닐(PVC), 폴리스테렌(PS) 및 폴리우레탄(PU)과 같은 다양한 종류의 범용 고분자 제품들이 광범위하게 제조 사용되고 있으며, 이들 제조현장에서는 화재 폭발 등으로 인해 산업재해가 많이 발생하고 있다. 이러한 사고를 예방하기 위해서는 과거에 발생한 사고사례를 수집 분석하여 사고특성 등을 파악하여 동종 혹은 유사사고 예방에 활용하는 것이 중요하다. 본 연구에서는 안전보건공단에서 운영하고 있는 산업재해통계시스템의 데이터베이스를 기초로 하여 SPSS를 활용하여 범용 고분자 제조공정별 재해분포 특성을 고찰하였다. 이들 결과는 범용 고분자 제조공정의 사고를 방지하고, 공정의 안전성을 확보하는데 활용하고자 한다.

A variety of general purpose polymer products such as polyethylene (PE), polypropylene (PVC), polyvinyl chloride (PVC), polystyrene (PS) and polyurethane (PU) are widely produced and used in the industrial field. Many industrial accidents have occurred due to fire and explosion at the manufacturing site. In order to prevent such accidents, it is important to collect and analyze accident cases that occurred in the past to identify the characteristics of accidents and to use them to prevent the same kind of accidents or similar accidents. In this study, the accident distribution characteristics of general polymer manufacturing process were examined by using SPSS based on the database of the industrial accident statistics system operated by the Korea Occupational Safety and Health Agency. These results can be used to prevent accidents in the general-purpose polymer product process and ensure the safety of the process.
