Unit 1Safety Management Systems安全管理体系1.Accident Causation Models1.事故致因理论The most important aim of safety management is to maintain and promote workers' health and safety at work. Understanding why and how accidents and other unwanted events develop is important when preventive activities are planned. Accident theories aim to clarify the accident phenomena,and to explain the mechanisms that lead to accidents. All modem theories are based on accident causation models which try to explain the sequence of events that finally produce the loss. In ancient times, accidents were seen as an act of God and very little could be done to prevent them. In the beginning of the 20th century,it was believed that the poor physical conditions are the root causes of accidents. Safety practitioners concentrated on improving machine guarding, housekeeping and inspections. In most cases an accident is the result of two things :The human act, and the condition of the physical or social environment.安全管理系统最重要的目的是维护和促进工人们在工作时的健康和安全。
安全工程专业英语Unit11. Because of the very rapid changes in these jobs and professions, it is hard for students to learn about future job opportunities. It is even more difficult to know about the type of preparation that is needed for a particular profession-or the qualities and traits that might help individuals succeed in it.由于这些工作和职业的飞速变更,其变化之快使得学生们很难了解未来有什么样的工作机会,更不知道为未来的具体职业生涯做出怎样的准备,也就是说学生们很难知道掌握何种知识、具备何种能力才能成功适应未来的社会。
2. The purpose of this article is to provide in depth information about the safety profession that should help students considering a career in this challenging and rewarding field.这篇文章将提供较为深入的安全专业方面的具体信息,它应该能够为安全专业的学生们在这个充满挑战也蕴含着发展机遇的职业中获得良好的发展而提供帮助。
