Better foundry hygiene through permanent mold casting.
Southern Research Institute, Birmingham, Alabama, Final Report 1976 Jan; :1-93
Gaseous and particular emanations from foundry casting production using permanent molds are compared with those using green sand molds. The results show that lesser emanations, both particulate and gaseous, are produced from operations involving permanent molds than with green sand molds. Data are given for dust loading, average hydrocarbon concentration, carbon-monoxide (630080), perylene (198550), benzo(a)pyrene (50328), benzo(e)pyrene (192972), carbon-dioxide (124389), methane (74828), ammonia (7664417), hydrogen (1333740), and cyanides. Of the operations producing the higher noise levels, those from use of the permanent mold are more readily susceptible to control than are those from the green sand mold operations.
