Safety technology in welding and cutting operation

1 Welding and cutting personnel shall receive safety education, professional safety theory and practical training, pass the examination, hold certificates and be physically healthy

2. Workers engaged in electric welding should understand the structure and performance of the welding machine, strictly implement the safety operation procedures, correctly use protective articles, and master the methods of first aid for electric shock

3. Welding and cutting the pipe sections and equipment of various containers (barrels, cans, boxes, etc.) containing inflammable and explosive materials (oil, paint, organic solvents, grease, etc.) strong oxides or toxic materials must comply with the corresponding provisions of the safety in welding and cutting in chemical enterprises, take safety measures, and obtain the hot work certificate of the enterprise and the fire management department before welding and cutting

4. The working place should have good natural lighting and local lighting when the fixture swings left and right during the day test, and should comply with tj34 "relevant provisions of enterprise lighting design standards for experimental results display" to ensure that the illumination of the working face reaches 50 ~ 100lx

5 . Heatstroke prevention and cooling and winter heating in the welding workplace shall comply with the relevant provisions of tj36 hygienic standard for industrial design

6. For gas welding and gas cutting in narrow and poorly ventilated trenches, tunnels, inspection wells, pipe sections, containers, semi enclosed sections, etc., the gas mixture of welding and cutting torches should be debugged on the ground, and the fire should be lit. Debugging and ignition at the workplace are prohibited. Torches for welding and cutting high-tech products from aerospace should be entered and exit with people

7. When welding and cutting in closed containers, tanks, barrels and cabins, the holes and holes of the welder's crops should be opened first to circulate the internal air, so as to prevent the welder from poisoning and scalding. If necessary, there should be a specially assigned person to monitor. When the work is completed and suspended, the welding, cutting torches and rubber hoses should go in and out with people, and should not be placed at the work site

8. It is forbidden to weld or cut on vessels, tanks, cabinets, pipelines and equipment with pressure or voltage and at the same time. Under special circumstances, when it is necessary to conduct impossible pressure relief and cut off the gas source, it is necessary to apply to the superior competent safety department for approval before hot work

9. The heat energy in welding and cutting shall be prevented from being transferred to the structure or equipment, so that the worker (4) can discharge the flammable insulation materials in the process of discharging the residual oil in the oil tank, or the flammable and explosive gases trapped can catch fire and explode
