With the development of industrialization of social production, there are more and more facilities on the production site in enterprises, and they are becoming more and more complicated. The color as a unique attribute of the material, as a communication language, has the irreplaceable characteristics of other substances in production management. Since color was successfully used in military and traffic safety management instructions in World War II, some industrialized countries have applied color to the safety management of their own industrial production processes. In 1952, the International Standardization Organization unified national security colors. The use of safety standards committee was established. In 1964, the "Safety Color" international standard was announced, which stipulated the significance and application of safe colors. Since then, according to the development of industry, color has been given more and more meaning, and it has been increasingly used in the safety management of production sites. In China, color has become an important part of the field safety management in modern enterprises. First, the use of color in the production site safety management principles The principle of the use of color in production site safety management is mainly the principle of ergonomics. Using the influence of color on people's psychology and physiology, improve the relationship between laborers and equipment and work environment; apply equipment that is convenient for humans to identify, enable laborers to operate safely and easily, and improve the work efficiency and accuracy of laborers. Identify the danger at the production site. Second, the use of color range The application of color in production site safety management is very extensive. Such as being used in the key parts of safety signs, traffic signs, gas cylinders, facilities, and equipment. From the perspective of total site safety management, the use of color in the production site safety management is mainly in the following aspects: (1) as the environmental color, adjust the working mood of the personnel; (2) as the color of the articles, to facilitate the personnel on the production site The identification of the items; (3) as the color of logo management, mainly for the application of safe colors in various security identification cards. In the production site, the use of color toning and complementation of colors (two colors are mixed in appropriate proportions to become achromatic, and the two colors complement each other) can regulate the working mood of employees, improve working conditions, and avoid mistakes. Reduce the visual fatigue of color, beautify the work environment, and reduce the probability of accidents such as visual fatigue or work fatigue. For example, in the various types of master control room on the production site, the main task of the staff is to monitor the production process through the computer, and the phenomenon of misoperation of eyesight fatigue occurs in the work. However, if the place is arranged for the operation, use the appropriate principles according to the above principles. The complementary effects of color and color and contrast between light and shade make the work surface complement the surrounding environment. As long as the staff periodically shifts their gaze to the surrounding environment for a period of time, it can reduce the visual fatigue of the color, thereby reducing errors in operation. The purpose of the operation phenomenon. Third, the article color People use color as a unique attribute of matter and artificially specify in the production site the colors and markings that the relevant substances should have. This color is a material identification color from the perspective of site safety management. Using the identification color of these substances, the on-site production staff can quickly identify the substances existing in the production and prevent the errors due to inaccurate identification. For example, in gas welding operations, oxygen cylinders are connected to red hoses, and acetylene cylinders are connected to black hoses. The color of the three-phase trolley power supply indicator light in the workshop is also artificially identifiable to facilitate installation and use. At present, the relevant national color identification standards for item identification are "Basic Identification Colors and Identification Symbols for Industrial Pipelines" (GB7231-87), "Cylinder Color Marks" (GB7144-1999), and "Insulated Conductors and Bare Conductor Color Marks". "(GB7974-87) and other standards. It should be noted that the identification of the color of substances present in production should be noted and cannot be confused with the use of safe colors in the production site. If the bottle of nitrogen stored on the production site is painted yellow, it does not mean that the substance has a safety meaning that warns the operator to move such a gas cylinder. Instead, the color is used as the identification color to facilitate identification of the gas bottle. medium. Fourth, the color of the logo management The use of color for logo management is the most widely used color for on-site safety management. It is mainly used for the application of safe colors and applications on signs and safety instructions. The security color is the color of the state to express the meaning of security information. It has four colors of red, yellow, blue, and green, indicating the meaning of prohibition, instructions, warnings, and prompts. Contrast colors are white and black. At present, the logo management color is widely used in the field of various safety signs, machinery and equipment, road traffic, goods packaging and other aspects. The relevant application standards promulgated by the government include "Guidelines for the Use of Safety Signs" (GB16179-1996), "Safety Colours" (GB2893-2001), "Safety Marks" (GB2894-1996), and "Safety Marks for Mines" (GB14161-93). , "Classification and Signs of Commonly Used Hazardous Chemicals" (GB13690-92), "Illustration of Occupational Hazards in Workplaces" (GBZ158-2003), "Road Traffic Signs and Markings" (GB5768-1999 instead of GB5768-86), " Hazardous Locations and Signs of Hoisting Machinery (GB15052-94). V. On-site safety management effectiveness The use of color for security management, although not a substitute for related safety practices and safety precautions, but the color can adjust the mood of production workers, help production personnel to quickly identify the material medium, causing production workers to pay attention to unsafe factors, from On the other hand, it has achieved the purpose of preventing accidents. At the same time, various signs of on-site colors and applied colors convey various information to the operators, which enables production operators to understand at a glance the risk factors and possible hazards existing on the site, and actively strengthen self-protection and management in production operations. Can prevent accidents from happening. Therefore, the correct use of color for security management can achieve the following management effects: 1. Improve the visual effect of on-site safety management. At the same time, visual management is based on national standards and corporate standards to standardize, standardize and institutionalize color safety management at the production site, and contribute to standardized safety management at the production site. 2. Strengthen the safety awareness of production site personnel and promote good safety habits. In the production site, various colors identify the material and risk factors in the production site, so that the hazardous substances and factors in the production site can make the on-site workers understand the on-site dangers through intuitive methods, strengthen the workers' safety awareness, and know what to do and pay attention to. What and what to prevent will help operators develop good safety habits. 3. The emphasis on the principle of visual highlighting can limit the unsafe behavior of workers and enable operators to improve their self-protection capabilities. The application of color to on-site safety management not only makes the company's production site safety management more intuitive, but also more importantly, it can reflect a company's good on-site safety management level. The use of good color in the production site, adjustment of working mood for employees, improvement of working conditions, avoidance of errors, reduction of color vision fatigue, beautification of the working environment have a positive effect, and have a good role in promoting production efficiency.
