Abstract
The major gases evolved from foundry molds have been determined in the laboratory by gas chromatography. The principal gases evolved during pouring and shakeout of castings include hydrogen (1333740), carbon-monoxide (630080), carbon-dioxide (124389), methane (74828), and other low molecular weight hydrocarbons with smaller amounts of ammonia (7664417), hydrogen-cyanide (74908), and sulfur-dioxide (7446095). The results of these experiments indicate foundry workers may be exposed to considerable amounts of carbon-monoxide evolved from green sand molds containing carbonous materials. Adequate ventilation and fresh make-up air may be necessary in the pouring area, the run-out lines where the casting cools in the sand and in the shakeout area. Other suggestions, including permanent mold techniques are suggested.
