Silica Dust - Why it's important when cutting concrete

Exposure to fine particles of silica dust causes silicosis. Silicosis is a severe lung disease that can be fatal. It is caused when fine particles get deep into the lungs, where coughing and breathing cannot remove them. Since quartz particles are sharp and angular, they create small cuts that damage and scar the lung tissue.
