Silica Awareness. The purpose of this presentation is to inform you to the serious health hazards of silica dust. Silica exposure can occur during sandblasting, grinding or cutting concrete or bricks, rock drilling, and sand and gravel operations. 1. Industries with Silica Exposure.
When products or materials containing crystalline silica are cut, sanded, drilled or ground into, a very fine dust is created. This dust is harmful when inhaled and can lead to silicosis. Silicosis can be fatal within five to 10 years – sometimes for people as young as 20 or 30.
5 Silica dust: This short presentation is designed to raise awareness among your employees of the risks from silica dust. It's aimed at anyone who works around dust or in an environment where materials containing silica are used.

Silicosis Is A Disease That Happens When Silica Dust Enters Your PPT. Presentation Summary : Silicosis is a disease that happens when silica dust enters your lungs and causes scar tissue to form. This makes it difficult for your lungs to take in oxygen.
Inhaling silica dust can cause silicosis, a serious and irreversible lung disease. It can be lethal. Silica damages the lung and causes scar tissue to form. This causes the lung tissue to become thicker. Silica exposure can also cause lung cancer. It is possible to have silicosis without showing any .
Respirable crystalline silica is a serious health hazard to workers. Workers exposed to silica dust are at an increased risk of developing serious silica-related illnesses. Companies must use engineering controls and work practices to protect workers from silica dust exposure at or above the PEL. PPT .
