Welding industry is not only hard, but also dangerous. It is very necessary for welders to pay attention to the protection of eye health.So do you know how welders protect their eyes?
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, without gaps or cracks, to prevent arc light entering.
A face mask with a curved front should also be used, rather than a straight one, as it reduces the amount of welding smoke entering the welder's breathing zone.
Lighter-weight fiberglass masks are usually recommended, while the newer nylon welding masks are lighter and increasingly popular with welders.Welding mask can also be connected to the hard helmet, used in the industry and construction of more dangerous occasions.
2. The welder must wear a filter to protect his eyes when working
The filter holder on the welding mask is used to install the protection plate and the filter glass or filter plate.
All filters or filters can penetrate a certain intensity of light, while filtering out a part of the arc light.
The filter coefficient of the mask filter should be selected according to the welding current.
Protective plates should be installed on the outside of the filter glass to protect the filter glass from being damaged by splash particles.The protection plate is generally made of glass plate or plastic plate.A magnifying glass can also be mounted behind the filter for a clearer view of the molten pool, while the filter glass should be ducible enough to prevent rupture after impact by flying objects.
3. The welder must wear protective clothing when working
The main purpose of wearing protective clothing is to prevent welding sparks from burning the face skin, and to reduce the stimulation of the eyes caused by strong light.
Spectral analysis of arc light shows that its ultraviolet intensity is very large, and this ray has a great harm to people's skin, especially the eyes. For the eyes, it can burn the fundus of the eyes and cause blindness.
Protective clothing must also be worn, because its penetration and thermal effect are also very strong, can burn the skin through the ordinary clothing, so not only the mask should be worn, but also the protective clothing.
1, welder's eyes were burned with fresh milk point eyes
Occurred after electric light sex ophthalmia, its simple emergency measure is to use the person milk that has boiled and cooling or fresh milk point eye, also can analgesic.
The method of use is to start every few minutes, and then, as the symptoms subside, the time of drinking human milk or milk may be extended appropriately.
2. After the welder's eyes are burned, use a towel to soak in cold water and apply the eyes
Still can use towel soak cold water compress eye, close eye to rest.
Arc light of welding and gas welding, ultraviolet lamp, sun-burning beach and plateau, the reflection of the sun can produce a lot of ultraviolet light caused by electrooptic ophthalmitis, especially welders.
If you watch arc welding for a long time without wearing protective eyes, your eyes will be stimulated by the strong ultraviolet light in the arc light, resulting in electro-optical ophthalmitis, which is commonly referred to as "hitting" the eyes by arc light.If the burn treatment is not good, the future is infinite.
3. Welder should pay attention to reduce light stimulation after his eyes are burned
After emergency treatment, in addition to rest, but also pay attention to reduce light stimulation, and minimize eye movement and friction.It can be cured in one or two days.
4, engaged in welding workers must do a good job of protection work
Workers engaged in welding work are prohibited from welding without wearing protective glasses to avoid unnecessary accidents.
