Employees were working on 8"" flyash line to unclog it.  System was shut down at time.  When the removed 2"" cap to insert air lance, material flushed out striking employee in face.  Safety glasses were worn, but dust flow blew them off.  No serious or permanent injury.  System has been redesign to reduce clogs and all caps now have valves to allow controlled opening.
