安全人机工程学，可以定义为：安全人机工程学是从安全的角度和着眼点，运用

Security ergonomics, can be defined as: Ergonomics is safe from a security point of view and focus, the use of ergonomic principles and methods to solve human security issues in conjunction with the surface of an emerging discipline. As a branch of applied science of ergonomics to safety as the goal, as the efficiency conditions, to keep pace with security as a prerequisite to targeting ergonomics ergonomics ergonomics and safety engineering has become a major branch. The relationship between researchers, mechanical, environmental three, to explore how to make the machinery, the environment in line with the characteristics of human morphology, physiology, psychology, makes a machine a coordinated environment, in order to achieve human capacity compatible with the requirements of operational activities, to create a comfortable, efficient and safe working conditions disciplines

Safety ergonomics can be defined as: safety ergonomics is a new discipline from the point of view of safety and focus, using ergonomic principles and methods to solve the safety problem of human-machine combination surface. As a branch of an applied discipline of ergonomics, it will be based on safety as the goal and work efficiency as the condition, and will go hand in hand with the ergonomics with safety as the premise and the work efficiency as the goal, and become an important branch of safety engineering. To study the interrelationship between people, machinery and the environment, to explore how to make the mechanical and environmental conform to the characteristics of human morphology, physiology and psychology, so that one mechanical and one environment can be coordinated, in order to achieve the human ability and the requirements of operational activities, and create comfortable, efficient and safe labor conditions.

Safety ergonomics can be defined as: safety ergonomics is a new subject which solves the safety problems of human-machine interface by using the principles and methods of ergonomics from the perspective and starting point of safety. As an applied branch of ergonomics, it takes safety as its goal and work efficiency as its condition. It will keep pace with work efficiency ergonomics which takes safety as its premise and work efficiency as its goal, and become an important branch of safety engineering. This paper studies the relationship among human, machinery and environment, discusses how to make the machinery and environment conform to the characteristics of human morphology, physiology and psychology, and how to coordinate the human, machinery and environment so as to meet the requirements of human ability and operation activities, and create comfortable, efficient and safe working conditions<br>
