Welder safety production knowledge

First, the importance of welding safety work

In order to protect the safety and health of welders and avoid accidents such as electric shocks, burns, fires and explosions and ensure the smooth progress of welding work, we must firmly establish the idea of ​​“safety first”, adopt certain protective measures, and formulate necessary safety operating procedures. .

Second, safety production general requirements

1 , comply with operating procedures, wear safety protection products.

2. When working at a height of 2.5 meters or more, wear a safety belt and do not put it on your shoulders.

3 , in the sealed compartment welding, ventilation should be noted and guardians should be set up.

4. There should be no welding near flammable or explosive materials. It should be at least 5 meters away from each other to prevent fire.

5. Do not weld on pressurized containers or pipelines and injure people with fireproof stars.

6 , welding equipment should have a good grounding.

7. In the event of an electric shock, the power supply should be cut off immediately. If the electric shocker is in a coma, artificial respiration should be performed on the spot until the doctor arrives.

8 , should drink more tea or refreshing drinks in the summer to prevent heat stroke, winter slip.

9 , prohibit pressure operations.

10. Use safe voltage for lighting.

11 , security inspection.

Third, the welder "does not weld"

1. The welder does not have a safe operation certificate, and no formal welder is present on the site. It cannot be welded alone.

2. All fire-fighting areas have not been approved and no safety measures have been taken. Firefighters have not arrived at the scene and cannot be soldered without permission.

3 do not understand the job site and the surrounding situation, can not blindly weld

4 do not understand the internal conditions of the weld, can not be welded

5. Containers containing inflammable, explosive and toxic substances cannot be welded without thorough cleaning

6. Equipment and parts with flammable materials as barriers, no reliable safety measures, no welding

7. Pressured or sealed pipes and containers cannot be welded

8. Piles of flammable and explosive materials are piled nearby. It cannot be welded without thorough cleaning or taking effective safety measures.

9. The operation site is in contact with the external unit and cannot be welded without ascertaining whether the external unit has affected it, or knowing the danger without taking effective safety measures.

10. The operation near the workplace is in conflict with the open flame and cannot be welded .

Fourth, safety technology

1 , to prevent electric shock

Wear insulated gloves, insulated shoes, or boots when welding.

Check the reliability of the welding equipment grounding.

Do not wear wet gloves to pull the switch or switch.

After starting the welder, if abnormality is found, it is necessary to cut off the power before proceeding.

Welding pliers, welding torches, and welding wires should all be well insulated to prevent short circuiting with the weldments, burning the welder or other equipment.

2 , to prevent burns, arc injuries

When welding, you should wear a trousers. When you perform all-position welding, you can wear leather trousers and leather cuffs.

When performing overhead welding, wear a working canvas cap that covers the neck.

The foot is protected by foot straps made of canvas or leather.

Wear leather gloves and protective glasses when welding.

When working at heights, splashing and the staff under the head of the welding rod should be prevented.

3 , prevent gas, smoke and dust hazards

Wear a static protective mask when welding, especially when working in a cabin.

Welding workplace should have good ventilation equipment. In the case of welding in the bilge double bottom tank or in other containers, exhaust fans shall be provided for ventilation.
