Welders should pay attention to occupational protection

Welders should pay attention to occupational protection With the development of social industrialization, the number of electric welders in the city is increasing, and problems have followed. In the production activities, welders face a wide range of occupational hazards. In order to reduce the occupational hazards of welders, individual protection must be carried out to effectively reduce the incidence of occupational diseases among welders.

The main occupational hazards faced by welders

1, the harm of arc light radiation

Arc light generated by welding mainly includes infrared rays, visible light, and ultraviolet rays. Among them, ultraviolet rays mainly cause harm to the human body through photochemical effects. It damages the eyes and exposed skin, causing keratoconjunctivitis (electrooptic ophthalmia) and cutaneous erythema.

2, the harm of metal smoke

The composition of welding fumes varies depending on the electrode used. The electrode consists of a core and a coating. In addition to a large amount of iron, the core contains carbon, manganese, silicon, chromium, nickel, sulfur, and phosphorus. The inner material of the core consists of marble, fluorite, rutile, pure salt, water glass, and ferromanganese. During arc welding, the arc discharge produces a high temperature of 4000°C to 6000°C, which produces a large amount of soot while melting the welding rod and the weldment.

3, toxic gas hazards

Under the high temperature and strong ultraviolet radiation generated by the welding arc, a large amount of toxic gases such as carbon monoxide and nitrogen oxides will be generated around the arc region. Can cause bronchitis, emphysema, pulmonary edema, may also cause human tissue due to lack of oxygen and necrosis.

How Welders Personal Protection

1. Improve the ventilation of the welding work site

Ventilation can be divided into natural ventilation and mechanical ventilation. Mechanical ventilation relies on the pressure generated by the fan to ventilate the air. The effect of dust removal and detoxification is good. Therefore, in a room with poor natural ventilation, welding must be performed in closed containers. Mechanical ventilation measures.

2. Strengthen personal protective measures for welders

Strengthening personal protection can prevent the harm of toxic gases and dust generated during welding. Workers must use appropriate protective glasses, face masks, masks, gloves, white protective clothing, insulated shoes, and must not wear short-sleeve clothing or roll up sleeves. If they work in closed containers with poor ventilation, they must wear it. Air performance protective helmet.

3、Strengthening labor protection protection and education for welders

Welding workers should carry out necessary occupational safety and health education, improve their self-prevention awareness, and reduce the incidence of occupational diseases. At the same time, the monitoring of dust hazards in electric welding workplaces and the medical work of electric welders should also be strengthened to promptly identify and resolve problems.

4, improve welding technology, improve welding processes and materials

By improving the welding technology, the welding operation will be mechanized, automated, and the human and welding environment will be isolated from each other, thus fundamentally eliminating the harm of the welding operation to the human body.

In today's rapid socio-economic development, welding operations involve almost all industrial fields, the number of welders has risen sharply, and occupational hazards in welding have become increasingly prominent. Although there are occupational hazards in the welding process that affect the health of the welder, Xiaobian believes that as long as effective protective measures are taken, the degree of harm can be reduced or reduced.
