• Description:
  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. [Description provided by NIOSH]
