What are the safety measures to prevent welding contact accidents?

The safety measures to prevent welding contact accidents are as follows:

1. Before work, carefully check whether the tools and equipment are in good condition, and whether the shell of the welding machine is reliably grounded. The repair of the welding machine shall be carried out by the electrical maintenance personnel, and other personnel shall not disassemble and repair.

2. Before work, the working environment should be carefully checked, and the work can only be started after confirming that it is normal, and wear labor protection supplies and safety helmets before construction. Wear a seat belt when working at height. Knock on welding slag, grinding wheels and wear flat glasses.

3. If the power cord of the welding machine or the welding machine fails, it should be repaired together with the electrician to prevent electric shock accidents.

4. The grounding wire should be reliable and safe, and it is not allowed to use scaffolding, wire cables, machine tools, etc. as grounding wires.

5. Welding in close to flammable places should have strict fire prevention measures, and if necessary, the consent of the safety officer must be used before work. After welding, it should be carefully checked that there is no fire source before leaving the work site.

6. Welded sealed containers and pipes should be vented first. To repair the container that has been filled with oil, it should be cleaned and the manhole cover or vent hole should be opened before welding.

7. When welding operations are carried out on the used tank, it is necessary to find out whether there are flammable and explosive gases or materials, and it is strictly forbidden to weld before being identified. Welding tongs and welding wires should be checked and maintained frequently, and if any damage is found, it should be repaired or replaced in time.

8. Welding hanging codes, reinforced scaffolding and important structures should have sufficient strength, and knock off the welding slag to carefully check whether it is safe and reliable.

9. When welding in the container, attention should be paid to ventilation and harmful smoke and dust should be discharged to prevent poisoning. There should be 2 people welding in a small container to prevent accidents such as electric shock. 10. The paint in the container is not dry, and the combustible gas is not allowed to be welded.

11. After the work is completed, the faucet wire joint must be disconnected, the scene must be inspected, the fire must be extinguished, and the power supply must be cut off.

The grounding protection of the welding machine is reliable, and the working grounding part should not be too far from the welding point. The primary and secondary wires of the welding machine are set in accordance with the requirements of the safety technical regulations, and the welding machine does not need to be powered off for a long time, and the overload protection system of the welding machine is normal!

Labor protection equipment for welders, insulated shoes, and welder gloves. Welding is prohibited in rainy and humid environments!

I'll just be brief.

1. Use insulators, which are not conductive.

2. Protect from being injured by sparks.

3. The welding machine should be grounded.

The upstairs is good, but the safety issues should be learned by themselves, don't ask, and control their own safety.

There are a lot of safety operating procedures for welders; High-altitude work, closed environment work, welding of oil containers, welding of pipelines, multi-person work... There is a thick book of safe operating procedures for welders.

There are also electricians who ask others, it is very dangerous, and the knowledge of playing with life must be studied by themselves.

Let's not be specific about this question! It can only be said that everything has to be done carefully by the staff themselves.

The use of opaque, insulated, and non-flammableplatesisolate and keep the site well ventilated. Discourage others from leaving the site to prevent welding fumes and forceUltraviolet raysdamages.

Welders must wear special protective work clothes, insulating gloves and insulated shoes correctly when welding. When using high-current welding, the welding tongs should be equipped with a protective cover. The freshly welded parts should be covered with asbestos boards in time to prevent burns caused by direct contact with feet and bodies.

The replacement electrode heads during high-altitude welding should be stacked centrally and should not be littered, so as not to burn the workers below.

Welding skills

When performing the upward welding operation, because the molten iron is easy to fall, it is necessary to take the form of spot welding, so that the sintering will be more firm. When the welding rod is replaced or the arc is temporarily stopped, when the welding rod is moved to the end of the weld of the hole, stop at the arc pit for a while, slowly raise the arc, and then lead to the base metal groove at the edge of the weld. At this time, the molten pool will gradually shrink, and there will generally be no defects after solidification.

Because there are certain technical and skill requirements, the effect and quality of the products welded by welders of different levels are quite different. Really high-level welders (national level) salaries are high.

1) Isolation protection.

The arc welding equipment should have a good isolation protection device to avoid contact between people and live conductors. The terminal of the welding machine should be inside the protective cover. For equipment with a bolt hole joint, the conductor of the bolt hole should be concealed in the plane of the insulating board.

The power cord of the arc welding machine should be set up in a place that is not easy to contact against the wall, and the length of the power cord should generally not exceed 2-3m. Each arc welding machine, equipment room, and arc welding machine and wall should leave at least 1m wide passage.

b) Good insulation.

Arc welding equipment and line live balance tung liquid conductor, to the ground, between the shell, or between phases, lines and lines, must have good insulation in line with the standard, and the insulation resistance shall not be less than lm

Safety measures and precautions for welding operations:

1. Wear welding overalls, insulated shoes, welding gloves, protective masks and other safety protection equipment for operation. Seat belts must be worn when working at height. Rain, snow, and strong winds of level 6 or above are not allowed to engage in outdoor operations.

After rain and snow, the water and snow should be cleared before operation.

2. Before operation, the welding machine and tools should be checked, such as the insulation of welding tongs and welding cables, the protective grounding of the shell of the welding machine and the various wiring points of the welding machine, etc., to confirm that the safety is qualified before operation. It is strictly forbidden to weld or cut on the early grinding parts of the heart stressed ridge in the area where flammable and explosive gases are diffused, in the pressure pipeline in operation and in the container containing flammable and explosive materials.

3. When the welding site is wet or the welder's body is sweaty and the clothes are wet, it is strictly forbidden to lean on the live steel plate or working piece, the welder should work on the dry insulating board or rubber mat, and the personnel should wear insulated shoes or stand on the insulating board.

4. Helmets should be worn for high-altitude operations. The welding cable should be tied tightly in the fixed place, and it is strictly forbidden to work around the body or on the back. The welder should stand on a stable operating platform to work, and the welding machine must be placed smoothly and firmly, with a good grounding protection device.

Welder safety training content:

The essence of welding, the unsafe factors existing in welding operations, the safety inspection of welding sites, the common sense and safety points of electric welding machines, the basic principles and safety points of gas welding and gas cutting, the problems that should be paid attention to in the use of acetylene cylinders, the problems that should be paid attention to in the use of argon (or carbon dioxide) cylinders, and the problems that should be paid attention to when using oxygen cylinders in use, transportation and storage.

As well as the problems that should be paid attention to in the use of welding torches and cutting torches, welding safety management, basic principles of fire and explosion prevention, basic measures to prevent electric shock accidents, safety measures for climbing welding and cutting operations, poisoning accidents and their prevention measures. For example, the safety inspection of the welding site can be specifically as follows: check whether the equipment, tools and materials in the welding and cutting operation site are neatly arranged.

Check that the welding site maintains the necessary passages. Check whether all gas welding hoses and welding cables are entangled with each other. Whether the cylinder has been removed from the workplace after use.

Check whether the welding work area is sufficient, and the work site should have good natural lighting or local lighting. Check whether all kinds of combustible and flammable materials are cleaned within 10m around the welding and cutting site.

It can cause damage to the eyes;

Toxic gases and dusts generated during the welding process can cause harm to the respiratory system;

Fire and ** may be caused during the welding process;

In the welding process, high-temperature welding equipment needs to be used, which is easy to cause disasters and burns.

In order to protect the safety and health of welders, the following precautions need to be taken:

Wear protective glasses, masks, gloves and other protective equipment to prevent ultraviolet and infrared rays from causing damage to the eyes and prevent burns;

Maintain ventilation during the welding process to prevent toxic gases and dust from causing harm to the respiratory system;

In the welding process, it is necessary to pay attention to fire and explosion prevention to avoid causing fire and fire;

Take extra care when using high-temperature equipment to avoid burns and fires.

Summary. First of all, in terms of contact with live objects, if you do not have professional knowledge, do not check or repair circuits and electrical appliances without permission, do not connect wires at will, and cut off the power in time when electrical appliances are found to be leaking, and ask professional people to repair them, and do not use a wet cloth with water or wet hands to touch the power supply, switches or bulbs.

Hello, the measures to prevent electric shock accidents are as follows.

Send it. Do not touch live objects at will, use electrical appliances according to the operation requirements and correctly handle the three parties of electric ignition.

First of all, in terms of contact with live objects, if there is no professional knowledge in large quantities, do not check or repair circuits and electrical appliances without permission, do not connect wires at will, and cut off the power in time when electrical appliances are found to be leaking, and ask professionals to repair them, and do not use wet cloth with water to imitate blindness or wet hands to touch the power supply, switch or bulb.

Second, in terms of the safe use of electrical appliances, you can't overload the power with the ridge wheel, and you need to pay attention to the load when using the electric socket to make the cherry jujubes, and you can't use several high-power electrical appliances at the same time, and at the same time, you should regularly check whether the wires, sockets and electrical appliances have the problem of road aging and leakage. Finally, properly deal with the problem of electric fire, once the electric fire is found, first cut off the power supply, and then extinguish the fire.

1. Insulation 1The function of insulation is to isolate the charged body with insulating materials to realize the electrical isolation between the charged body and between the charged body and other objects, so that the equipment can work safely and normally for a long time, and at the same time can prevent the human body from touching the live part and avoid electric shock accidents, so insulation plays a very important role in the safety of electrical fiber.

In some cases, the operator of hand-held power tools must wear insulated gloves, wear insulated shoes (boots), or stand on the insulated mat (platform) to work, and use these insulated safety appliances to make people and the ground, or make people and tools of the metal shell, which includes the connected metal conductor guess orange, isolated. This is a simple and feasible safety measure at present.

<> causes of fires and accidents during welding are manifold. First, the red-hot particles of sparks, molten metal and slag are splashed around during welding, which ignites nearby flammable and explosive materials and causes fires. Second, due to the long-term dragging of the soft wire of the electric welding machine on the ground, the insulation is damaged, cracked, and short-circuited.

The third is that the electric welding ground wire is randomly connected and caused by fire. Fourth, the insulation of the welding machine itself and the power cord is damaged, resulting in a short circuit and heating. Fifth, when the container containing flammable and explosive materials is transported, it is heated due to the fact that the container is not cleaned, replaced, welded, and heated.

In addition, welding in the warehouse where flammable and explosive is stored can also cause accidents because no feasible preventive measures are taken. Therefore, the following precautions should be strengthened during welding operations:

During welding operations, flammable and explosive materials shall not be placed within 5m near the site, and oxygen cylinders and acetylene cylinders shall be more than 10m away. When welding at high altitude, the flammable and explosive materials below should be removed to prevent the hot spatter and the hot electrode head from falling into it and causing fire and accidents.

The soft peibu line of the electric welding machine should be avoided dragging on the ground as much as possible, and if it needs to be dragged, it must also be gently dragged to avoid the soft wire being cut by hard and barbed objects. If the insulation layer of the flexible wire is damaged or aging, it should be bandaged or updated in time. The ground wire of the welding machine should not be connected indiscriminately.

If the insulation of the welding machine itself is found to be damaged, it should also be repaired and replaced in time.

When welding containers, first of all, it should be clear whether the container has been filled with flammable and explosive materials, if it has been contained, it should be thoroughly cleaned and replaced before welding, and it is strictly forbidden to weld containers and equipment with liquid pressure, gas pressure and electricity.

Welding operations shall not be carried out in the room and site where flammable and explosive materials are stored, and if welding is required, the flammable and explosive materials must be removed first, and strict isolation measures should be taken to prevent welding sparks and red heat particles from splashing and causing fire accidents.

Wooden boards and wooden bricks should not be used as liners during welding operations, so as not to cause heating and burning of wood materials, and iron plate liners should be used.
