Finally, the construction site layout Ergonomics design. Before design, ergonomics research for security objects, methods, purpose and other aspects of learning; standardized design in combination, can give full play to the role. From the point of view of ergonomics to analyze the design requirements of the working space, which contains potentially dangerous work space and equipment, hazardous area protection analysis. Ergonomics is because of human-centered design, all necessary to study human behavior habits. Humans have many sexual instinct adapt to the environment, they are in the long-term human activities, due to environmental and human interactions and form, this instinct is called human behavior habits. People adapt to the environment through the analysis of the behavior of habit, during the construction sites ergonomic design of these habits into account, inspired from these habits out on the construction site in Ergonomics design ideas. The ergonomic design and layout from the construction site are expanded, comprehensive on-site layout planning and rational distribution, in order to facilitate safe operation; according to the actual situation of the project for construction of foundation pit and underground garage Human Security Division ergonomic design; structures for scaffolding safety of Ergonomics design. The ergonomic design is just for the safety of construction sites, the design process of the construction sector are discussed in the application of ergonomics. Ergonomics in the construction of industrial facilities designed to take into account the human factor, the operating environment must take into account when designing human habits; This design consists of these elements, but the focus is from a security point of view, or for the security services.
