The electric welding industry is not only hard work, but also has certain dangers. It is very necessary for electric welders to pay attention to protecting eye health. So do you know how welders protect their eyes? In this issue, the editor will introduce to you how to protect the eyes of electric welders and what should we do after being burned?
Precautions before work
1. Welders must wear welding masks to protect their eyes when working
Welders must wear welding masks or filters. At the same time, the mask used must be in good condition with no gaps or cracks to prevent arcing from entering.
In addition, an arc-shaped face mask should be used instead of a straight face mask, because the former reduces the amount of welding fumes entering the welder's breathing zone.
Commonly recommended: Use a lighter weight fiberglass face shield, while the newer nylon welding face shields are lighter and increasingly popular with welders. Welding helmets can also be attached to hard helmets for use in hazardous situations in industry and construction.
2. Welders must wear filters to protect their eyes when working
There are filter clips on the welding helmet for mounting the protective plate and filter glass or filter plate.
All filters or filter plates let in a certain intensity of light while filtering out a portion of the arc.
The filter coefficient of the mask filter should be selected according to the welding current.
A protective plate should be installed on the outside of the filter glass to protect the filter glass from being damaged by splashing particles. The protective plate is generally made of glass plate or plastic plate.
A magnifying glass can also be installed behind the filter plate to observe the molten pool more clearly, and the filter glass should have sufficient toughness to prevent breakage after being hit by flying objects.
3. Welders must wear protective clothing when working
Wearing protective clothing is mainly to prevent the sparks generated during electric welding from burning the facial skin, and at the same time reduce the irritation of the eyes caused by the strong light generated.
Spectral analysis of arc light shows that the intensity of its ultraviolet rays is very large, and this kind of ray is very harmful to human skin, especially the eyes. For the eyes, it can burn the fundus and cause blindness.
At the same time, its penetrating power and thermal effect are also very strong, and it can burn the skin through ordinary clothes. Therefore, not only a mask, but also protective clothing should be worn.
4. Site protection should also be done well
When welding things, whether it is cold or hot, the fan should be turned on when there is no wind in the air. People should not weld things in the wind tail, not only to prevent the inhalation of toxic gases, but also to prevent the toxic gases from getting into the eyes. The damage to the eyes should not be underestimated.
When welding stainless steel parts or welding things with stainless steel electrodes, when the welding parts are not completely cooled, do not check the welding seam at a close distance without any protection of the eyes, because there may be the possibility of welding slag splashing to the eyes.
What to do if your eyes are burned
1. The welder's eyes are burned with fresh milk.
After the occurrence of electro-optic ophthalmia, the simple emergency measure is to instill the eyes with boiled and cooled human milk or fresh milk, which can also relieve pain.
The method of use is to start once a few minutes, and then, with the relief of symptoms, the time of ordering human milk or milk can be appropriately extended.
2. After the welder's eyes are burned, apply a towel to the eyes with cold water
You can also use a towel soaked in cold water to compress your eyes and close your eyes to rest.
The arc light of electric welding and gas welding, ultraviolet lamps, the seaside and the plateau of the hot sun, the sunlight reflection of the snow-capped mountains can all produce a large amount of ultraviolet rays and cause electro-optic ophthalmia, especially for electric welders.
If you watch the arc light without wearing protective eyes for a long time, the eyes will be stimulated by the strong ultraviolet rays in the arc light, resulting in electro-optic ophthalmia, that is, the arc light "hit" the eyes. If the burns are not handled properly, the consequences will be endless.
3. After the welder's eyes are burned, they should pay attention to reducing the stimulation of light
After emergency treatment, in addition to rest, pay attention to reducing light stimulation, and try to reduce eye movement and friction. It usually heals within a day or two.
4. Workers engaged in electric welding must do a good job of protection
Workers engaged in electric welding work are prohibited from conducting electric welding operations without protective glasses, so as to avoid unnecessary accidents.
What does a welder eat is good for the eyes
1. Eat more fruits with vitamin A
When vitamin A is deficient, the ability of the eyes to adapt to the dark environment decreases, and in severe cases, night blindness is likely to occur. Vitamin A can prevent and treat dry eye disease, so you should get enough vitamin A every day.
Fruits rich in vitamin A include apricots, melons, peaches and papayas.
2. Eat more fruits with vitamin B group
A considerable amount of free vitamin B2 is stored in the retina of the eye. Lack of vitamin B group can lead to photophobia, tearing, burning and itching, visual fatigue, and eyelid spasm.
Fruits rich in vitamin B are: bananas, grapes, pears, kiwifruit and so on.
3. Eat more fruits with vitamin C
There is a high content of vitamin C in the lens of the eye, which acts as an antioxidant to protect the eyes. If you lack vitamin C, you are prone to cataracts. Therefore, eating more fruits containing vitamin C can increase the content of vitamin C in the eye lens, improve the effect of antioxidants, and reduce the damage of free radicals to the eyes.
Fruits rich in vitamin C are: guava, kiwi, strawberries, tomatoes, etc.
4. Eat more yellow-green fruits
These fruits contain lutein and zeaxanthin, and once these two pigments enter the body, they accumulate in the light-sensitive tissues at the back of the eye, which protect the eye by filtering blue light.
