What are the requirements for safety, environmental protection and health management in the spherical tank area? Strict process discipline and operating discipline, and perform operations in accordance with process technical regulations and operating methods ; Personnel entering the tank area are not allowed to wear shoes with iron nails. ; According to regulations, when entering the tank area, you must wear labor protection equipment. Before entering the tank area, you must touch the static eliminator to eliminate static electricity on the human body. ; In flammable and explosive places, staff are prohibited from wearing or taking off clothing that easily generates static electricity, and are not allowed to comb their hair, pat their clothes, or use chemical fiber fabrics to wash equipment. ; Clean up combustible materials in the oil tank area and prevent gas accumulation in low-lying areas ; During the pouring, circulation and transfer process of the spherical tank, the fluid flow speed should generally not exceed the planned 4m/s. The oil inlet flow rate of the empty tank should not be greater than 1 m/s. When the oil inlet is immersed in oil, the flow rate can be increased, but the flow rate should not be greater than 6m/s at any time. ; When dehydrating the spherical tank, people must stand on the air outlet, and the opening of the dehydration valve should be controlled to prevent dehydration from entraining air and polluting the environment. ; When going to a tank area where hydrogen sulfide may exceed the standard for inspection or dehydration, you must carry a corresponding detector. ; Strictly prevent over-temperature and over-pressure of the spherical tank. When the storage medium temperature exceeds 30°C or the pressure of the spherical tank reaches 0.05MPa lower than the maximum over-operating pressure of the tank, process spray cooling can be carried out. If necessary, the low-pressure gas valve can be opened to relieve pressure. ; For spherical tanks that need to be depressurized for maintenance or production, the pressure should be decompressed slowly to prevent the refrigeration effect of the medium accompanying the pressure release from causing the tank temperature to drop to low temperatures, thereby affecting the spherical tank. Usually, during the depressurization process, the tank temperature needs to be controlled to not be lower than 5℃ ; During the antifreeze season, special attention should be paid to mixing, heating and dehydrating the dehydration package to prevent freezing damage to pipelines, valves and equipment.

Safety, environmental protection and health precautions in the spherical tank area: 1. Strict process discipline and operating discipline, and perform operations in accordance with process technical regulations and operating methods. ; 2. Prevent sparks from the impact of metal objects in the spherical tank area, and personnel entering the tank area are not allowed to wear shoes with iron nails according to regulations. ; 3. When entering the tank area, you must wear labor protection equipment according to regulations. Before entering the tank area, you must touch the static eliminator to eliminate static electricity on the human body. ; 4. In flammable and explosive places, staff are prohibited from wearing or taking off clothing that easily generates static electricity, and are not allowed to comb their hair, pat their clothes, or use chemical fiber fabrics to wash equipment. ; 5. Ensure good grounding and regularly check the static grounding wire on the floating roof. ; 6. Open fires are strictly prohibited in the oil tank area. Reliable fire prevention measures must be taken when using fire in engineering construction, and the work ticket and fire ticket systems must be strictly implemented. ; 7. Clean up the combustible materials in the oil tank area, and it is strictly prohibited to discharge oil products into the rainwater system. ; 8. The firewall in the oil tank area must be complete, the drainage ditches in the site must be smooth, the rainwater valve must be opened in time when it rains, and the rainwater valve must be closed in time after the rain stops. ; 9. The light-transmitting hole of the oil tank should be closed tightly during normal production. ; 10. During the filling, circulation and transfer process of the spherical tank, the fluid flow speed should generally not exceed the planned 4m/s. The oil inlet flow rate of the empty tank should not be greater than 1 m/s. When the oil inlet is immersed in oil, the flow rate can be increased, but the flow rate should not be greater than 6m/s at any time. ; 11. When performing scale inspection, temperature measurement, and dehydration operations on oil tanks, people must stand on the air outlet. ; 12. When going to tank areas where hydrogen sulfide may exceed the standard for inspection or dehydration, you must carry the corresponding detector. ; 13. When entering oil tanks and sewage wells (pools), you must apply for equipment entry tickets and implement corresponding preventive measures. ; 14. The foam firefighting pipeline of the oil tank should be inspected regularly. ; 15. Use an automatic dehydration system for dehydration and reduce or eliminate the use of manual dehydration. Manual dehydration strictly controls the valve opening to prevent dehydration from carrying oil and polluting the surrounding environment. ; 16. The oil tank should be stationary for more than 30 minutes before the oil tanker inspects the tank, measures temperature, and takes samples. ; 17. Strictly prevent over-temperature and over-pressure of spherical tanks. When the temperature of the storage medium exceeds 30°C or the pressure of the spherical tank reaches 0.05MPa lower than the maximum over-operating pressure of the tank, process spray cooling can be carried out. If necessary, the gas phase line connection valve on the top of the tank can be opened to directly release the pressure to the low-pressure gas system. ; To ensure the safety of the ball tank ; 18. Process switching must follow the principle of opening first and then closing, and strictly prevent the pipeline from holding pressure or the pump being evacuated. ; 19. For spherical tanks that need to be depressurized due to maintenance or production, the depressurization should be carried out slowly to prevent the refrigeration effect of the medium accompanying the pressure release from causing the tank temperature to drop to low temperatures, thereby affecting the spherical tank. Generally, the tank temperature needs to be controlled to not be lower than 5 during the depressurization process.℃ ; 20. For pipelines that require pressure relief and venting due to production, the valve opening must be controlled when venting the pipeline to prevent large amounts of ice (frost) in the pipeline. ; 21. During the anti-freeze season, special attention should be paid to mixing, heating and dehydrating the dehydration package to prevent freezing damage to pipelines, valves and equipment.
