Developing exposure controls by material balance modeling.
NIOSH 2001 Feb; :1-50
Emission source characterization and detailed work task - exposure analysis were conducted at a gray iron foundry for the purpose of designing an exposure control system. The source characterization revealed that the emission of carbon monoxide from cooling molds is highly variable from mold to mold, and the quantity of CO emitted does not appear to be directly associated with the size of the casting. The unpredictable nature of the CO emissions made it infeasible to implement a model of ambient CO concentrations based upon the size and number of castings produced, however the detailed work task - exposure monitoring revealed the specific steps in the work process that made the greatest contribution to personal CO exposures. This information provided the basis for a set of recommendations on control options, and the foundry management has taken them under consideration.
