The reason for the birth of safety ergonomics

was due to the many safety issues that humans encounter when using machines and devices. In the past, machines and devices were designed with a primary focus on their functionality and efficiency at the expense of human safety when using them. This led to many accidents and injuries, even some fatal. As technology continues to evolve, more and more attention is being paid to the safety of machines and equipment. Safety ergonomics was created to address this issue.

It is an interdisciplinary discipline involving many fields such as psychology, engineering, anthropology, and biomechanics. Its aim is to design safer, easier to use and more efficient machines and devices by studying the process of human interaction with them. The evolution of safety ergonomics can be traced back to the early 20th century. During World War I, the military began using airplanes and other mechanical devices, but the design of these devices did not match human physiological and psychological characteristics, resulting in many accidents. In order to solve this problem, the U.S. military began to study the process of human-machine interaction and came up with some design principles, such as visibility, readability, comprehensibility and controllability of human-machine interfaces. With the passage of time, safety ergonomics has gradually become an independent discipline and has been widely used in industry, transportation, medical and other fields. For example, in the field of aviation, the research results of safety ergonomics are used to design safer and easier-to-use airplane cockpits; in the field of healthcare, the research results of safety ergonomics are used to design safer and easier-to-use medical devices. Safety ergonomics was born to solve the safety problems encountered by human beings when using machines and equipment, and its development history is inseparable from the development of science and technology, and its scope of application is becoming more and more extensive.
