4 Preparation before maintenance
4.1 Before the start of equipment maintenance work, an "Equipment Maintenance Safety Operation Permit" should be obtained. The format of the "Equipment Maintenance Safety Operation Permit" is shown in Appendix A. 4.2 According to the requirements of the equipment maintenance project, an equipment maintenance plan should be formulated to implement maintenance personnel, maintenance organization, and safety measures. 4.3 The person in charge of the maintenance project shall organize the maintenance personnel to the maintenance site according to the requirements of the maintenance plan, explain the maintenance projects, tasks, and maintenance plans clearly, and implement the maintenance safety measures. 4.4 The person in charge of the maintenance project shall be fully responsible for the maintenance safety work and designate a person to be responsible for the safety work of the entire maintenance operation process. 4.5 If the equipment maintenance requires high-altitude operations, fire, earthwork, circuit breaking, hoisting, blind plate removal, and entering the equipment, etc., the corresponding safety operation permit shall be obtained in accordance with the provisions of HG23011, HG23012, HG23013, HG23014, HG23015, HG23016, and HG23017.
4.6 The cleaning, replacement, and handover of the equipment shall be the responsibility of the unit where the equipment is located. An analysis report shall be provided after the equipment is cleaned and replaced. The person in charge of the maintenance project shall work with the equipment technicians and process technicians to check and confirm that the equipment, process treatment and blind plate plugging meet the maintenance safety requirements. 5 Safety education before maintenance
5.1 Before maintenance, safety education must be conducted for the personnel participating in the maintenance work. 5.2 Safety education content:
5.2.1 Relevant maintenance safety rules and regulations that must be followed in maintenance work. 5.2.2 Unsafe factors and countermeasures that may exist or appear at the maintenance site and during the maintenance process. 5.2.3 Correct wearing and use of personal protective equipment and supplies during maintenance work. 5.2.4 Maintenance work items, tasks, maintenance plans and maintenance safety measures. 6 Safety inspection and measures before maintenance
6.1 The scaffolding, lifting machinery, electric welding tools, hand-held power tools, wrenches, pipe clamps, hammers and other tools used in maintenance work should be inspected. Any tools that do not meet the safety requirements of the operation shall not be used. 6.2 Reliable power-off measures should be taken to cut off the power supply of the electrical appliances on the equipment to be repaired, and after the start-up recheck confirms that there is no power, hang the "Do not start" safety sign at the power switch and lock it. 6.3 The gas protection equipment, fire-fighting equipment, communication equipment, lighting equipment and other equipment used in maintenance work should be inspected by a dedicated person to ensure that they are intact and reliable, and are placed reasonably.
6.4 The ladders, railings, platforms, iron counters, covers, etc. at the maintenance site should be inspected to ensure safety and reliability. 6.5 The blind plates used for maintenance should be checked one by one, and the high-voltage blind plates must be used after flaw detection. 6.6 The mobile electrical tools used for maintenance should be equipped with leakage protection devices. 6.7 For maintenance sites with corrosive media, a water source for flushing should be available. 6.8 For pits, wells, depressions, ditches, steep slopes, etc. at the maintenance site, they should be filled or covered with covers flush with the ground. Fences and warning signs can also be set up, and red warning lights should be set up at night.
6.9 The flammable and explosive items, obstacles, oil stains, ice and snow, stagnant water, waste and other debris that affect the safety of maintenance at the maintenance site should be cleaned up.
