The increasing use and distribution of chemicals are causing serious chemical accidents such as fires, explosions, and leaks during manufacturing and handling. In most cases, all risks caused by chemicals are classified as accidents due to defects in process facilities, human errors, and multi-cause accidents. Among chemical accidents caused by human errors, accurate analysis of accidents caused by the complex action of various types of human failures is required. Based on the accident investigation reports that occurred in South Korea from 2010 to 2017, chemical accidents caused by human failure were analyzed, and the fundamental causes were derived by classifying them into human error and violation. Human failure was analyzed according to the classification criteria for human failure of health and safety executive (HSE). As a result of the analysis, several types of human failure acted in combination to be a more significant cause of chemical accidents; incorrect application of process rules and procedures, inappropriate chemical information, lack of education, and defects in the current safety regulation were analyzed as the main causes. In addition, the cause of human errors was presented through case studies of chemical accidents in South Korea.
化学品的使用和分布日益增加，在制造和处理过程中会导致严重的化学事故，如火灾、爆炸和泄漏。在大多数情况下，由于工艺设施缺陷、人为错误和多因事故而导致的所有化学品风险都被归类为事故。在人为错误导致的化学事故中，需要准确分析各种人为故障复杂作用引起的事故。基于 2010 年至 2017 年在韩国发生的事故调查报告，对人为失误导致的化学事故进行了分析，并通过将其分类为人为错误和违规行为来得出根本原因。根据健康和安全执行官 (HSE) 的人为错误分类标准，对人为失误进行了分析。分析结果表明，几种类型的人为失误共同作用是导致化学事故的更重要原因；对工艺规则和程序的不正确应用、不适当的化学信息、缺乏教育以及现行安全法规的缺陷被分析为主要原因。此外，还通过韩国化学事故的案例研究提出了人为错误的原因。
