I. Entering the construction site must comply with safety operating procedures and safety production discipline, and special operators must hold a certificate. 2. Those who are engaged in pipeline installation should implement national and industry relevant safety technical procedures. Third, you must wear a helmet and hats to enter the construction site to correctly use labor protective supplies.
. Use vehicles to transport pipes, pipes, and be tied firmly. Manpower handling, consistent ups and downs. Through ditch, pit, well, you must set up a passage. You must not overweight. You should not touch, touch, and voltage power wires. You must use rolling bars to prevent pressure. Rolling the bar, rolling the tube, no one.
. Use a saw tool, saw, tube cutter, and sand wheel cutting machine to cut the tube. You must flatten the stamp and do not be too strong. All should be intact, the motor wiring is correct, and the ground is reliable. When operating, you should stand on the side.
6. Cut off the cast iron pipe with a gramon, wearing protective glasses, no curls on the top of the gramzi. 7. The installation pipes should be straight, and the adaptive elbow component should be connected at the change. 8. When moving the pipeline, it is not allowed to touch or pressure the outer skin of the power cord to prevent electric shock.
. The air pressure meter, water pressure meter, and decompression valve of the flame bending machine should be sensitive and reliable, and the anti -fireware must be safe and effective. The operating site should be equipped with a fire extinguisher, and the distance between the ignition and the cylinder is not less than 10m.
Ten. When connecting the parts of the pipeline, the movement should be coordinated, and the hands must not be placed at the joint and flange junction. 11. When turning the workpiece, prevent sliding and dumping.
This. The hand -type sand wheel machine should have a protective cover. The protection of the zero wire is reliable. The power supply wire has no leakage and no leakage.
It, the edge of the soil -to -pipe ditch during the trench trench must not be less than 1.2m. The materials and tools used must not be stored by the groove. During construction, it should be regularly check whether the sides of the groove wall are loose and cracks or water seepage. It may be timely when there is a collapse and should be added and supported in time.
Is when the tube tube, grooves, and pit depth is greater than equal to 1.5m, it must be placed or supported by the soil quality. Support, prohibit the use of solid wall support, and set up, escalators and lifting brackets.
. Fifteen, manually pipe into the trench, the incorrect and ground piles used must be firm, and no one shall be in the groove.
. When the pipeline is lifted, the crane tools should be intact and reliable. 17. When the electric tools are screamed, no one must be approached under the board and the wall. 18. High -level operations must be tied to a safety belt correctly.
. The pipes should be cleaned with acid and alkaline liquid, and protective supplies should be worn. The acid -base liquid groove must be covered and an obvious logo is set.
. The use of chemicals is used for ductandy. The venue should be well ventilated. Wearing protective supplies, flammable materials should be eliminated first.
Twenty -one, qi and electrical welding operations, the flammable items in the operating area should be removed first, and Mars should be prevented from splashing in the gap and leaving fire. In conjunction with gas and welding operations, wearing protective glasses or masks should be worn.
. When repairing underground pipes, analyze the gases transporting toxic, flammable, and explosive medium pipes. If you exceed the allowable quantity, measures such as pumping should be taken, and the operator should be operated after passing the qualification. The operator should wear anti -virus masks.
