    Title: Accelerated Silicosis
    Type: Text Slide
    • May develop after 5 to 15 years of exposure
    • Silicotic nodules detectable by chest X-ray after only a single intense exposure
    • May lead to progressive massive fibrosis and death
    Speaker Notes: Accelerated and acute silicosis result from shorter exposures at higher concentration. The accelerated form, which requires only 5 to 15 years to develop differs from the simple form in that silicotic nodules are detectable by chest X-rays after only a single intense exposure. Accelerated silicosis may lead to progressive massive fibrosis and death. Extremely small sized particles may contribute to the development of accelerated silicosis.
