6. The basic principles of hot work
6. 1 When hot work is carried out on equipment, containers and pipelines for producing, storing and transporting combustible materials, the source of materials should be cut off first and a blind plate should be added. After thorough purging, cleaning and replacement, the manhole should be opened for ventilation, and hot work can be carried out only after the test analysis is qualified. After the analysis is qualified, if the fire is over 1 hour, the fire analysis must be carried out again; Or fire can be used in pipes and containers filled with water.
6.2 In the normal production area, all movable and immovable fire sources are not allowed to be hot; Anyone who can be removed for hot work must be removed and moved to a safe place for hot work.

6.5 The equipment is undergoing major and medium repair. Due to the heavy fire fighting workload, all flammable, combustible and toxic materials should be sent to the tank farm outside the device, and blind plates should be added to isolate them from the device.
6.6 When using fire inside the equipment, the safety management standards for equipment operation must be observed; When working at heights with fire, the safety management standards for working at heights must be observed at the same time; Motor vehicles entering production areas such as production plant areas, tank farms and oil depots shall be implemented in accordance with the Regulations on the Administration of Motor Vehicles Entering Production Areas.
