Breathing zone and general area air samples are taken to determine mold-room employees' exposure to formaldehyde (50000), phenol (108952), methylene-diphenyl-diisocyanate (MDI) (10031751), phenylpropylpyridine, benzene (71432), xylene (108383) (1330207), toluene, and petroleum distillates in the no-bake mold department of Corhart Refractories (SIC-3297), Louisville, Kentucky. Results show that employees in the department experience transient and mild mucous membrane irritation due to fumes emanating from the silica (7631869) sand. Results do not indicate any reason to suspect the development of chronic conditions due to exposure to any of the substances at existing concentrations.
