| Abstract |
Foundry workers are known to be exposed to crystalline silica. In most foundries, metal castings are made through the use of sand moulds. Exposure to crystalline silica occurs during the moulding process, during shakeout operations and during metal finishing. This report describes the inspection made by NIOSH in a foundry. Personal sampling for respirable silica was conducted throughout the plant. This inspection discovered three cases of overexposure to crystalline silica and the employer was cited for various violations under existing U.S. regulations. A plan for reducing exposures was discussed and agreed with the employer. It involved various technical measures, including exhaust ventilation, and the supply of respirators and protective clothing as an interim measure. |
