Acute SilicosisA complication of intense exposure to respirable crystalline silica, associated with sandblasting, coal mining, or any other job in which there is heavy exposure to fine particulate silica. Unlike classic silicosis, acute silicosis appears within a few weeks to 5 years of initial exposure.

Clinical findings Rapid onset of severe respiratory impairment, dyspnoea, cough, weakness, weight loss, often leading to death.
