Environmental and breathing zone samples were analyzed for respirable free silica (7631869) at Grand Gulf Nuclear Power Facility (SIC-1721), Port Gibson, Mississippi, in February, 1983. The evaluation was requested by the local union after painters complained of chest pain, dizziness, and nausea while spray painting in areas without adequate ventilation. Medical interviews were conducted and work practices were observed. Respirable dusts containing 60 percent silica had concentrations of 8.2 milligrams per cubic meter (mg/m3). The OSHA standard for such dusts is although symptoms such as nasal, throat, and eye irritation, and dermatitis were frequently reported. In a followup survey, the effectiveness of a water spray system to reduce silica dust exposure and the resistance of rubber gloves worn by painters to penetration by methylene-dianiline (101779) when applying epoxy resin surfaces were evaluated. Dust concentrations were still 1.6 to 42.5 times the OSHA standard. Significant methylene-dianiline concentrations were found inside the gloves. The authors conclude that a health hazard from silica containing dusts exists. The gloves worn by painters were unsuitable for applying preparations containing methylene- dianiline. Recommendations include using respiratory protection and cotton inner gloves inside the outer gloves.
