由于我国科学技术的不断进步,生产设备现代化程度的不断提高,对于人类的不安全行为因素的要求和标准也就相应的提高。其目的是:以避免或减少由于人的不安全行为所导致的事故和损失。在这种情势下,我们如何最大限度的预知和防范由于人的不安全行为因素所造成的工作上的差错,最大程度地减少损失,保证职工的安全与健康工作就成了我们当前安全工作的一个重要的课题。运用PSI周期理论进行超前的科学预报、是指导安全生产工作的一门新学科、新方法、而且较其它学科优越。主要特点是:PSI周期理论在安全管理工作中可以起到超前的作用,这一点历年来在安全管理工作中 Due to the continuous improvement of science and technology in our country and the continuous improvement of the modernization of production equipment, the requirements and standards for the unsafe behavior factors of human beings have also been correspondingly raised. Its purpose is to: Avoid or reduce accidents and losses caused by human unsafe practices. Under such circumstances, how can we maximize the prediction and prevention of work mistakes caused by unsafe human factors, minimize losses and ensure the safety and health of workers becomes our current safety work? An important issue. Using PSI cycle theory to advance the scientific forecasting is a new discipline and new method that guides the work of safety production, and is superior to other disciplines. The main features are: PSI cycle theory can play a leading role in the safety management work, which over the years in the safety management work
