为阐明安全科学的研究对象,基于历史方法和逻辑方法,回顾该学科的研究内容,论述主要观点的优缺点,继承已有观点的合理成分,提出“三位一体”的安全科学研究对象新观点,即危险源+隐患+事故(职业病)。研究表明:危险源是引发事故(职业病)的根本原因;隐患是导致事故(职业病)的直接原因;事故(职业病)是存在隐患的危险源失控造成的后果。 In order to clarify the research object of safety science, based on historical methods and logical methods, reviewing the research content of the subject, discussing the advantages and disadvantages of the main point of view, inheriting the reasonable elements of the existing point of view, putting forward the new viewpoint of the “scientific research object” of “Trinity” , That is, the source of danger + accident + accident (occupational disease). Research shows that: the source of danger is the root cause of the accident (occupational disease); the hidden danger is the direct cause of the accident (occupational disease); and the accident (occupational disease) is the consequence of the out-of-control danger source of danger.
