VIDEO: The Shocking Results Of Silica Dust Exposure

Posted by Echo Barrier on Feb 5, 2019 10:18:00 AM | Silica dust


Silica does not normally present a major threat to health because it is bound up in materials and not present in the air we breath. But modern work practices disturb this and release silica into the air, where it can enter the lung. This can present a serious occupational hazard.

Exposure Times

Exposure to silica can be dangerous whether it is a long term exposure or a briefer acute exposure. Exposure to silica for even a few months has been shown to cause serious problems if the levels present are high enough. It is not safe to assume that one is only at risk if working in a field where there is potential for silica exposure over decades.

Why Silica Is So Dangerous

The reason silica is so dangerous is due to the nature and fine shape of the small particles involves. Our natural mechanisms for cleaning our lungs, which will work for a time for other dangerous substances unless they are overwhelmed, simply cannot cope with silica particles. They become permanently lodged in the lung, where their irritant action can stimulate harmful responses that can lead to scarring and reduced lung function over time.


Effect On Health

Exposure to silica can lead to cancer, as silica is a known carcinogen, as well as silicosis in one of three forms: classic silicosis, accelerated silicosis, or acute silicosis. Classic or chronic silicosis, the most common type, occurs after decades of low-level exposure in work settings, and only becomes apparent when progressive lung decline becomes noticeable. 

Accelerated silicosis is similar but can happen after only a few years of exposure, with weakness and weight loss apparent. Acute silicosis can happen after only a few months' exposure to high levels, leading to severe shortness of breath, and it can be fatal.

This new video from the Operational Safety & Health Administration illustrates the frightening reality of years of exposure to crystalline silica particles can have on someone's health.
