What are the safety precautions during maintenance operations?

1.Wear labor protection equipment according to the regulations during maintenance work.

2.When overhauling equipment, the "power-off listing" system must be strictly implemented.

3.If you work under mechanical equipment, you should hang a sign saying "under repair, do not turn the machine" on the equipment under maintenance. Repair machinery with wheels, apply triangles.

Plug the wheels to prevent rolling.

4.When working at height, you should wear a safety belt.

Take precautions. Pay attention to safety when repairing, and do not drop tools and parts up and down. In order to avoid accidents or damage to tools.

5.If more than one person is required to operate in the repair, there must be a special person to command and cooperate closely with each other.

6.Venting must be carried out before overhauling the equipment.

7.When overhauling in explosion-proof areas, pay attention to fire and explosion prevention, and use explosion-proof tools safely.

8.When disassembling the equipment, the disassembly force should be uniform to avoid excessive force and other phenomena such as bruises.

9.Be diligent in observation during cross-work to prevent objects from falling and injuring people.

10.When disassembling the equipment, it should be carried out in order, and the relative position of the disassembled parts should be marked and recorded, and properly kept.

11.When disassembling and assembling quenching parts such as bearings, copper rods or wooden rods should be used to cushion the hammering, and not directly hit with a sledgehammer.

12.When overhauling interconnected parts, the connected parts must be stuck so that they cannot slide before they can be overhauled.

13.When installing chain or gear transmission machinery, it is strictly forbidden to rotate the machinery arbitrarily.

14.Check the inverted chain when hoisting the equipment.

Check whether the lock is normal, and check whether the rack car is normal to prevent the equipment from slipping and injuring people.

15.For aerial work of more than two meters, a climbing operation ticket must be issued, and safety belts must be used throughout the process.

16.After the overhaul is completed, the tools should be inventoried to prevent them from being left in the machine.

17.During the overhaul, it is not allowed to touch the sliding surface, rotating parts or threaded holes with your hands.

18.Before the test run, check whether the power supply is connected correctly, and carefully check all parts of the machine to confirm that it is correct before driving.

1. The maintenance of high-voltage equipment must be reported to the chief in advance, and the work can only be carried out after the consent of the chief of duty.

2. The maintenance of high-voltage equipment must strictly implement the work ticket.

system, fill in the first section according to the actual work needs.

1. Two types of work tickets.

3. The power failure of high-voltage equipment must strictly implement the operation ticket system, use insulating rods and transmission mechanisms to pull the high-voltage switch, wear insulating gloves, and lock or hang signs on the operating handle after cutting off the power supply.

4. When checking the electricity, you must wear insulating gloves and insulated shoes, according to the voltage level.

Use an electroscope.

Check the power of each phase on both sides of the equipment or each phase of the line.

5. After verifying that the equipment or line is confirmed to have no voltage, the maintenance equipment or line can be short-circuited and grounded.

6. Install a grounding wire.

It should be carried out by two people, first to the ground end and then to the conductor end. The order of dismantling is reversed, and insulation protective equipment should be worn when dismantling.

7. The grounding wire should use multi-strand soft and bare copper wire with a cross-section of not less than 25 2 and a special wire clamp, and it is strictly forbidden to use the winding method to carry out a grounding short circuit.

8. When working in a partial power outage, the human body should keep a safe distance from the live part, and a shield should be installed, and a temporary shield and the live part should be maintained. 7m (6kV) distance, and hang the warning sign of "Stop, High Voltage Danger".

9. Regardless of whether the on-site substation and distribution high-voltage equipment is live or not, the maintenance personnel shall not work beyond the barrier.

10. The items removed during the overhaul should be placed in a unified order, and it is forbidden to throw the items indiscriminately.

11. After the overhaul is completed, the public tools and personal tools should be counted, and the temporary short-circuit grounding wire can be removed only after a comprehensive inspection.

12. Report the maintenance results to the value and make maintenance records.

Dear <> will be happy to answer for you. 1.During the maintenance period, the safety operation procedures are strictly implemented to achieve regular and orderly operations.

2.During the overhaul, strictly check the safety devices of the equipment to ensure the safety performance of the equipment. 3.

During the overhaul, the operator is required to let the personnel wear safety protective equipment and strictly abide by the safety operation procedures. 4.During the maintenance period, it is necessary to discover the potential safety hazards of the equipment in time and take effective measures to prevent the occurrence of safety accidents.

5.During the overhaul period, the safety of author-type bureau personnel should be fully considered to ensure the safety of the operation. <>

The safety precautions during inspection and maintenance operations are as follows:

It is necessary to identify dangerous and harmful factors in the workplace and confirm the corresponding safety control measures; Carry out macro safety education and training for inspection and maintenance personnel; Equip inspection and maintenance personnel with appropriate labor protection products; Handle all kinds of work tickets.

It reads as follows:

1. Make full use of the old equipment, and reuse the old is to "make full use of the old resources" to achieve the purpose of saving.

2. In the project, if there are duplicate parts used in multiple projects, then these duplicate machines that can be eliminated or shared are called old equipment.

Recycling is the process of turning waste into reusable materials, as opposed to reuse, which simply refers to the reuse of a product.

According to the Environmental Protection Agency, 13% of solid waste in the United States (i.e., waste disposed of through waste collection systems) is recycled. In contrast, 14% of solid waste is incinerated and 73% is disposed of in landfills.

Safety precautions for equipment maintenance:

1. Before equipment maintenance.

1. Preparation of labor protection supplies. Before entering the workshop, you must wear work clothes, labor protection gloves, protective glasses and other sensitive labor protection equipment.

2. Analyze the maintenance work to be carried out, the possible risks and hidden dangers, and take corresponding measures.

3. If you need to climb the height, you must wear climbing safety equipment, and warning signs must be placed below the climbing operation to remind passers-by to pay attention to falling objects.

4. Before equipment maintenance, check whether the electrical, hydraulic and pneumatic power sources are disconnected, and hang warning signs such as "repairing" and "prohibiting closing" at the switch or special person to supervise them, and the guardian shall not engage in operation or do anything unrelated to guardianship.

5. Before equipment maintenance, it is necessary to inspect, analyze and understand the causes and current status of the equipment rental posture and branch barriers. It is necessary to check whether there is floating medicine in all parts of the equipment, and if so, it must be repaired only after taking measures.

6. Before repairing, maintaining and maintaining the equipment, it is necessary to cut off the power supply and gas source of the main power supply of the equipment and the control elements such as photoelectric switches, travel switches, proximity switches, pneumatic components, etc., and the auxiliary components can only be repaired, maintained and maintained after confirming that the equipment will not malfunction.
