The Textbook of Three-level Safety Education and Training for Employees in Production and Business Units (Second Edition) is divided into three parts, which comprehensively expounds the contents of safety education and training at factory level, workshop level and shift level, explains the general contents in detail, delineates the learning scope, and puts forward learning suggestions in combination with the actual contents.

It is hoped that all production and business units can make use of the textbook "Three-level Safety Education and Training for Employees in Production and Business Units" (Second Edition) to fulfill the obligation of providing employees with three-level safety training and education at the factory level, workshop level and team level as stipulated in the Law on Safety in Production and the Provisions on Safety Training for Production and Business Units, so as to truly lay a solid foundation for safety production management. At the same time, I hope that the employees can be inspired and educated from the Third-level Safety Education and Training Textbook for Employees in Production and Business Units (Second Edition), understand the knowledge of safety in production, master the skills of safety in production, improve the ability of accident prevention and emergency response, and truly do not hurt themselves, others, and make their own contributions to the healthy development of safety in production.
