1, eye injury:
(1) Arc holes are caused by ultraviolet rays emitted during welding. My eyes are swollen and painful, and there is a lot of watery eyes.
(2) The thermal barrier is caused by arc welding and infrared rays emitted by molten metal, so the vision is not clear.
2, skin irritation
Caused by arc irradiation. The skin will turn red and dark after being irradiated by arc light for a long time, especially for workers who are exposed to welding for the first time. Within two to three days after being irradiated by arc light, the skin has a dull pain of chapped skin, accompanied by peeling of the surface skin.
3. Metal fog heat
This heating is caused by the inhalation of new metal oxides produced during welding.
4. Toxic smog
When some alloys or covered electrode are used in welding, toxic fumes may be generated, such as lead, picks, beryllium and fluoride.
5. Toxic gas
Toxic gases such as nitrogen oxides, ozone and phosgene may be produced during welding, which may cause bronchial and lung irritation.
Welding is welding and related technologies and processes.
Extended data:
Emergency measures for eye injury caused by welding;
Step 1: Close your eyes, apply a cold towel to your eyes and change it every 20 minutes.
The second step, in order to prevent infection, you can use eye drops, eye ointment and so on.
It should be reminded that recovery within 1-3 days after onset will not cause permanent damage, but don't be injured by ultraviolet rays for many times or for a long time.
In addition, in addition to the above three points, we need to pay attention to the following points.
1. Dropping boiled and cooled human milk or fresh milk into eyes can relieve pain and protect eyes. Apply a wet and cold towel to your eyes and change it every 20 minutes.
2. Close your eyes and rest to reduce the stimulation of light and the friction of eye movement. Wearing sunglasses can cover your eyes and make them feel comfortable.
