1. A dedicated person must be responsible for equipment maintenance, and a major maintenance headquarters should be established. Develop a detailed maintenance plan, which should include specific occupational safety and health prevention and safeguard measures.
2. Hazard identification, risk assessment and necessary control measures must be carried out for the maintenance equipment. For some major projects, corresponding safety technical measures (safety measures, purging plans, blind plate positions, work progress, etc.) must be formulated, and the "five fixes" should be achieved, that is, the construction plan, operating personnel, and safety measures should be determined , determine project quality and determine work progress.
3. Foreign engineering construction units participating in equipment maintenance must have relevant qualifications and abide by the rules and regulations of chemical enterprises.
4. Relevant personnel participating in equipment maintenance must receive safety education related to the work content. Whenever two or more people are working, one person must be designated to be responsible for safety. Special operations personnel (electricians, welders) should work with certificates in accordance with national regulations.
5. Before construction, the project leader should conduct safety technical briefings to all staff. When explaining specific projects, safety measures and precautions must be explained clearly. Before operation, the implementation of safety measures should be checked and confirmed.
6. For maintenance project operations, relevant regulations must be strictly implemented and relevant procedures must be handled (including stopping and starting equipment, adding and removing blind panels, and tickets for construction, maintenance, fire, working at heights, and entering restricted spaces) ) system and corresponding safety technical specifications.
7. Before the device maintenance work, it must be purged, cleaned and replaced.
(1) Designated personnel must be responsible for purging, cleaning, and replacing equipment containers and pipelines.
(2) All equipment, containers, and pipelines containing flammable, toxic, and corrosive media should be thoroughly purged and replaced so that they do not contain residues and residual gases. The sampling and analysis results should comply with safety requirements. Technical requirements.
(3) It is necessary to ensure that it does not flow, explode, burn, or poison, and ensure the quality of purging and replacement.
8. Management of adding and removing blind panels.
(1). A dedicated person must be designated to be responsible for unified management.
(2) The addition and removal of blind plates must be numbered and registered to prevent leakage and removal.
(3) If flammable, explosive, toxic and harmful media are retained in equipment containers such as towers, tanks, pipelines, etc., blind boards should be installed at the entrances and exits or at the connections with the equipment, and warning signs should be hung. Card.
9. All equipment, containers, and pipelines that require maintenance must meet fire conditions to ensure construction safety.
(1). Fire management implements a fire work permit system. Hot work operations must have a valid hot work permit.
(2) If there is a fire on equipment, containers or pipelines containing flammable media, the source of the material should be cut off first and the blind plate should be blocked. After purging, cleaning and replacing, the manholes should be opened for ventilation. , and only after the gas detector passes the test, can the fire be started.
(3) Before starting a fire, a dedicated person should conduct inspection and analysis and keep records. (Combustible Gas Detector)
(4) For high-altitude fire operations, shielding measures should be taken to prevent sparks from flying, trenches, valve wells, and sewer wells should be water-sealed, and low-level equipment and pipelines should be sealed. , valves, instruments, etc. should be blocked or closed.
(5) All combustible materials must be removed around open flame operations, and flammable liquids or flammable gases are not allowed to be discharged around the operations.
10. During the maintenance period, safety managers and full-time (part-time) safety personnel at all levels must go to the installation site to conduct safety inspections and supervision. Conduct on-site inspection and confirmation of each operation link to ensure that it is under safe control.
11. Guardians of various types of operations such as working on fire, using electricity, working at heights, and entering restricted spaces must perform safety responsibilities, supervise carefully, and conduct comprehensive inspections of the operation and completion sites (such as extinguishing fires) , cut off the power supply, clear obstacles, etc.).
12. Personnel entering the installation site must strictly implement relevant labor protection regulations, wear labor protection equipment, and are strictly prohibited from carrying fireworks.
13. It is necessary to inspect the tools and protective equipment used in construction operations (scaffolding, springboards, ropes, hoists, driving vehicles, safety driving lights, driving light transformers, electric welding machines, insulating shoes, insulating gloves, electric test pens, and gas masks). , dustproof supplies, safety helmets, safety belts, fire-fighting equipment, etc.) to check and confirm the safety and reliability.
14. During the maintenance period, the fixed alarm probe at the installation site must be properly protected.
15. When constructing containers, equipment, pipelines, etc. containing flammable and explosive materials, explosion-proof (such as wood, copper, etc. non-sparking) tools must be used, and it is strictly prohibited to use iron tools to knock or collision.
16. When opening equipment manholes, the internal temperature and pressure should be reduced to below safe conditions, and the openings should be made from top to bottom. When opening the bottom manhole, you should first open the bottom discharge and slag valve, and then proceed with the operation after confirming that there is no residual material inside, and be alert to any blockage. It is strictly forbidden to remove all the screws before the manhole cover is loose.
17. Temporary protective measures must be added to damaged or dismantled railings and platforms, and they should be restored to their original state after construction is completed.
18. Ensure that leakage switches, cables, and electrical appliances are in good condition.
(1) Distributors for temporary power use must be equipped with leakage protectors, and the operating current and operating time of the leakage protection must meet the coordination requirements of the superior and subordinate levels.
(2) Mobile tools and handheld power tools should have one machine, one gate and one protection.
(3) The wiring of the electric welding machine must be standardized. The welding wire should be lapped on the welding piece as close as possible. The insulation of the wire and secondary wire must be intact. The exposed ground wire must not be lapped on the device or equipment. On the frame, it is not allowed to pass through the sewer or overlap the welding wire on the operating equipment (pipeline).
19. The voltage of portable lights shall not exceed 36V, and the voltage of temporary lighting operating in particularly humid places or metal equipment such as towers and tanks shall not exceed 12V.
20. Personnel working at heights should wear safety belts that are suitable for the work content. The safety belts should be hung on solid components above the construction work. The safety belts should be hung high (fastened) and used low.
21. It is prohibited to throw objects, tools and debris from high altitudes. Machine tools, materials, industrial waste and other items must be placed in designated locations.
