(1) The large-scale machining workshop shall be of grade I and II fire-resistant rating, and other simple buildings shall not be built in the workshop.
(2) For used oil rags, oil cotton yarn and oil sawdust. CNC processing should be concentrated in the metal cylinder (box) with cover and processed every day.
(3) It is forbidden to use gasoline, alcohol and other wiping machine tools in the workshop. The residual oil after washing parts shall not be poured into the sewer or trench at will, but shall be poured into the container at the designated place for unified treatment.
(4) Gasoline shall not be stored in the workshop. The storage capacity of machine oil and kerosene should not exceed one day’s consumption. CNC processing and storage in covered iron drums. If the storage capacity is large, a special oil storage room should be set up. No other combustible materials shall be stored in the oil storage room, and the indoor ventilation shall be maintained. The electrical switch shall be installed in the outdoor distribution box.
(5) In the workshop, due to careless use of the stove for heating, using waste oil cotton yarn to light a fire, throwing cigarette butts, match sticks and so on, fires are often caused. Therefore, strict management should be carried out on site smoking and stove heating.
(6) If it is necessary to carry out open flame welding and cutting in the workshop, the surrounding environment should be checked first, combustible materials should be removed, and the nearby machine tools should be covered with refractory materials. At the same time. Special person must be assigned to be responsible for monitoring, and residual fire should be checked and eliminated after operation.
(7) The electrical equipment of the machine tool must be checked frequently, and the hidden danger should be eliminated in time. It is not allowed to run with a fault. CNC processing, installation, removal, maintenance, debugging must be operated by professional electricians according to the regulations. The metal shell of all electrical equipment shall be reliably grounded, and its grounding resistance shall not be greater than 4 Ω.
