The
cement manufacturing company XYZ has just discovered that one of their processing
operations is putting extremely large amounts of crystalline silica dust into the
air. Brent, who was hired just 6 months ago, has noted how tired he has become
lately, and how difficult it is to breath.
If Brent has silicosis, it probably is which type?
Accelerated
Probably not, unless Brent previously worked
around crystalline silica. Accelerated silicosis takes 5 to 10 years to develop with
moderate exposures. Try Again
Acute
Yes. Acute silicosis can develop within
weeks due to high levels of silica exposure.

Chronic
Probably not, unless Brent has a history of
working around crystalline silica. Chronic silicosis results from prolonged exposure
to small amounts of silica, taking up to 10 or 15 years to develop. Try Again
