Why is it necessary to control welding fume in workshop?

In recent years, the stricter EIA system has put some companies under certain pressure. Some companies may still feel that EIA is unnecessary and increase the burden on their own companies. But is that really ture? Is EIA really necessary for factories? Let's take the fume pollution in the welding workshop as an example to see how important it is to control the welding fume in the welding workshop!

Mr. Li is a welder in a metal manufacturing factory. Recently, after using an electric welder, he always feels uncomfortable, itchy, dry, and coughs violently from time to time. After going to the hospital for a careful examination, it was found that Mr. Li was suffering from respiratory diseases due to long-term exposure to a heavily polluted environment. It turned out that recently Mr. Li's factory was rushing forward, working overtime to do electric welding, and then Mr. Li had not taken the necessary protective measures, so that fume entered the body and caused respiratory diseases.

Yes, the respiratory disease mentioned in the above story is caused by welding fume. The hazards of welding fume to the human body are far more than this:

Welding fume usually contain harmful substances such as acetaldehyde, rosin acid, isocyanate, sulfide, etc. When they invade human liver, lungs, cardiovascular and blood through the respiratory tract, these toxic substances will swallow human health and cause many occupational diseases, such as lung cancer, asthma, bronchitis, respiratory infections, etc.

Among the occupational diseases caused by welding fume, pneumoconiosis is the most serious. Pneumoconiosis is caused by long-term inhalation of welding fume and dust during the production process. It is a disease mainly caused by fibrosis of lung tissue and causes irreversible damage to the lungs.

In general, if welding workshop wants to do environmental assessment well, it must be equipped with a corresponding fume purification system, such as welding fume purifier, to reduce the total concentration of fume in the workshop and prevent fume pollution from harming human health.

At present, the more common welding fume purifiers on the market are as follows:

1 - The mobile welding fume purifier has a 360-degree freely hovering exhaust arm. The appearance of the equipment is small, flexible and movable. It is suitable for small welding workshops and factories with fewer welding stations;

2 - Central welding fume purifier has a pipeline network, through one-to-one pipeline collection, to complete the welding fume collection and purification of the whole workshop, generally, this is suitable for factories with more workstations and larger workpieces;

3 - The self-circulating welding fume extraction system integrates the advantages of mobile and central in design, avoiding the defects of mobile and central. It does not require pipeline laying as a whole, plug and play, and the high-efficiency fan has a strong fume collection and purification function, and the purification radius can reach 15m. It is generally suitable for tall workshops and factories who have irregular parts and large workpiece.

The above is what I want to share with you. It is necessary for the welding workshop to be equipped with welding fume purification system. Relevant companies must not take a fluke and take it lightly.
