3.2 Work inside equipment
Enter various towers, spheres, kettles, kettles, chains, guard tubes, boilers, boilers, pipelines, tunnels, cathodies, pits, sewers or other places within the chemical production area as well as non-business work inside equipment. 4 Safety requirements for work inside equipment
4. Safety requirements
All channels on the equipment that are connected to the outside world should be effectively separated from the outside world: the power supply on the equipment connected to the outside world should be effectively cut off. 4.1.1 Pipeline safety isolation can be achieved by using whiteboards or removing a pipeline. Water-filled doors cannot be used to replace whiteboards or remove pipelines.
4.1.2 Power supply can be effectively disconnected by removing the fuse and turning off the power switch, and adding warnings. The State Petroleum and Chemical Industry Bureau 1599-09-29 issued 20000301 implementation
4.2 Cleaning and replacement
HG 23D17—1999
When entering the equipment, the equipment must be cleaned and replaced gradually, and the requirements are met. 4.2.1 Quantity: 18~21.
4.2.2 The gas in the market should comply with the safety control regulations of chemical enterprises. 4.2.3 The irritable gas liquid should comply with the safety management system of chemical enterprises. 4.3 Ventilation
Measures should be taken to maintain good air circulation in the equipment. 4.3.1 Open all doors, door holes, door openings, dampers, and smoke doors for self-ventilation. 4.3.2 Mechanical ventilation can be used when necessary: ​​4.3.3 Use ducted air to supply air. Before ventilation, the medium and wind source in the duct must be measured and analyzed for confirmation. 4.3.4 Oxygen or high-oxygen air is not allowed to be filled into the equipment. 4.4 Regular monitoring
4.4.1 Within 3 minutes before operation, the gas in the equipment must be analyzed. After the analysis is qualified, the equipment can be entered after obtaining the "Safe Operation Permit in the Equipment". ≤The format of safe operation in the equipment is shown in the appendix. 4.4.2 The sampling points have representatives.
4.4.3 Regular monitoring should be strengthened during the operation. When the situation is abnormal, the operation should be stopped immediately and the personnel should be evacuated. After the operation site is processed, the sampling and analysis are combined before the operation can be continued.
4.4.4 When the operator is preparing the equipment, the operation tools should be taken out of the equipment and not left in the equipment. 4.4.5 When screening materials with associated isolating agents, continuous analysis should be performed and non-ventilation measures should be taken. 4.5 Protection measures
4.5.1 When entering the equipment that cannot meet the requirements of special cleaning and disposal, corresponding protective measures must be taken. 4.5.1.1 In the absence of English or books, you should wear a gas mask. 4.5.1.2 In flammable and explosive environments, workers should wear non-sparking plastics and chemical fiber fabrics. 4.5.1.3 In corrosive environments such as alkali, workers should wear protective gear. 4.5.2 The voltage inside the equipment should be less than 86V, and the voltage should be less than or equal to 12V when working in a damp and narrow environment. 4.5.3 Hand-held electric tools that exceed the safety voltage must be equipped with leakage protection devices as required. 4.5.4 Temporary seven-wire installations: They should be installed and removed as required. The line insulation should be ensured to be good. 4.6 Safety measures for multiple types and cross operations 4.6.1 Measures should be taken to avoid injuries between the upper and lower parts. 4.6-2 A safety fence or safety guard should be set up.
