NIOSH conducted a survey of S-and-S Corporation's welding and fabrication operations in Cedar Bluff, Virginia in July of 1974. Environmental sampling was conducted for iron-oxide (1309371) fumes in the Trailer, Frame and Parts departments. Personal breathing zone samples and area samples were collected. Additionally, samples were tested for phosgene (75445), oxides of nitrogen, ozone (10028156), carbon-monoxide (630080), perchloroethylene (127184), and trichloroethylene (79016). Iron-oxide concentrations detected were well within the standards with one exception. Large double doors on either side of the building were open, thereby providing adequate natural ventilation. However, during the winter months this natural ventilation would be severely curtailed. Personal samples concentrations were significantly higher than area concentrations due to the lack of local exhaust ventilation. Perchloroethylene and trichloroethylene samples were above limits at the degreasing tanks with open lids. Welding operations were performed without the required protection.
