crystalline silica (quartz, cristobalite, tridymite) for periods as short as 6 months has caused acute silicosis. Symptoms of acute silicosis include (but are not limited to): shortness of breath, cough, fever, weight loss, and chest pain. Acute silicosis is a rapidly progressive, incurable lung disease and is typically fatal.
