Tiny particles generated during grinding and welding processes are commonly called dust. | |
|
|
|
Dust can enter into the lungs and may cause respiratory disorders such as Pneumoconiosis. | |
|
Protection Equipment: Always wear a respirator or dust mask approved for the materials you are working with. |
|
|
|
Although the size of dust particles may differ depending on the material, those sized 0.1 to 5?m generally end up in the lungs most frequently. | |
|
|
|
Most dust is inhaled during breathing. | | |

Welding fumes are tiny airborne particles generated during arc welding, such as MAG or MIG, when the base material and welding wire are heated to the point of vaporization. Prolonged breathing of welding fumes can cause these particles to accumulate in the lungs and may result in “welder’s lung”, which is a kind of pneumoconiosis.

Many steel parts are zinc plated for corrosion resistance. When the zinc coating is vaporized during cutting, welding, or brazing of galvanized steel, exposure to these fumes can cause an acute allergic condition known as “Metal Fume Fever”. The symptoms of metal fume fever are very similar to those of common influenza. This condition can be avoided by adequately ventilating the work area and wearing a respirator approved for use with zinc fumes. | | |
