5S: SEIRI, SEITON, SEISO, SEIKETSU and SHITSUKE, also known as "Five Principles" or "Five Conventional Laws". \ x0d \ 5s \ x0d \1s-seiri \ x0d \ Definition of finishing: distinguish what is needed and what is not, and only the necessary items are kept on site. \x0d\ Finishing purpose: \x0d\ ① Improve and increase the working area; \x0d\ ② There is no sundries at the site, and the streets are unobstructed, thus improving work efficiency; \x0d\ ③ Reduce collision opportunities, ensure safety and improve quality; \x0d\ ④ Put an end to mistakes and accidents such as mixing and placing in management; \x0d\ ⑤ It is beneficial to reduce inventory and save money; \ x0d \ 6. Change work style and improve work mood. \x0d\ The significance of sorting: separate out the unnecessary people, things and things, then deal with the unnecessary people, things and things, classify all kinds of stagnant items actually placed on the production site, and distinguish between those needed and those not needed; Secondly, we must resolutely clean up unnecessary items on the site, such as used materials, redundant semi-finished products, chips, scraps, garbage, waste products, redundant tools, scrapped equipment, workers' personal daily necessities, etc. The focus of this work is to resolutely clean up unnecessary things at the scene. The front and rear of each station or equipment in the workshop, the left and right of the passage, the up and down of the workshop, the inside and outside of the toolbox and the dead corner of the workshop should be thoroughly searched and cleaned to make the best use of everything. \ x0d \ \ x0d \ 2s-Seiton \ x0d \ Definition of rectification: Necessities shall be located according to regulations, placed in an orderly manner and clearly marked. \x0d\ The purpose of rectification is not to waste time looking for goods, improve work efficiency and product quality, and ensure production safety. \x0d\ Significance of rectification: Quantify and locate the people, things and things needed. After the completion of the previous step, scientifically and reasonably arrange and place the items that need to be left at the production site, obtain the required items as quickly as possible, and complete the operation under the most effective rules and regulations and the simplest process. \x0d\ Key points of rectification: \x0d\ ① Items should be placed in a fixed place and area to facilitate searching and eliminate errors caused by mixing; \x0d\ ② The placement of articles should be scientific and reasonable. For example, according to the frequency of use of items, things that are often used should be placed nearby (such as the work area), and things that are occasionally used or not commonly used should be placed far away (such as concentrated in a certain place in the workshop); \x0d\ ③ Visualize the articles, so that the quantitatively loaded articles can be seen and counted, and the areas where different articles are placed are distinguished by different colors and marks. \ x0d \ 3s-Seiso \ x0d \ Definition of cleaning: removing dirt in the site and material garbage in the operation area. \x0d\ The purpose of cleaning is to remove "dirt" and keep the site clean and bright. \x0d\ Significance of cleaning: It is the first step of self-maintenance to remove the dirt in the workplace and make the abnormal source easy to find, mainly to improve the productivity of equipment. \x0d\ Cleaning points: \x0d\ ① Clean your own belongings, such as equipment and tools, without relying on others and adding special cleaning agents; \x0d\ ② Cleaning equipment focuses on equipment maintenance. Cleaning equipment should be combined with point inspection of equipment, that is, point inspection and repair; Cleaning equipment should be lubricated at the same time, and cleaning is also maintenance; \x0d\ ③ Cleaning is also for improvement. When cleaning the ground, flying debris and oil-water leakage are found. It is necessary to find out the reasons and take measures to improve them. \ x0d \ 4s-Seiketsu \ x0d \ Definition of cleaning: systematize and standardize the implementation of sorting, rectification and cleaning, and keep its achievements. \x0d\ Cleaning purpose: Seriously maintain and adhere to the effect of sorting, rectifying and cleaning to keep it in the best condition. \x0d\ Significance of cleaning: By persisting in and deepening the activities of sorting, rectifying and cleaning, the root causes of safety accidents can be eliminated.
