| Resumen |
Airborne particles are categorized into three main types: large particles greater than 100μ in diameter which can cause irritation to the eyes, nose and throat, but are not fine enough to reach the lungs; medium particles between one and 100μ in diameter which include pollen, large bacteria and coal dust, as well as dust produced during industrial processes including welding and grinding; they pose the greatest health risk, because they are able to penetrate the lungs where they settle; small particles of less than one micron in diameter which also pose serious health risks; they include viruses, small bacteria, metallic fumes and pigments. Given that there are an estimated 400,000 welders in the United States, it is important to understand the potential health consequences of particle inhalation and to choose the proper ventilation, filtration and protection systems for protecting welders from airborne particles. |
