Heavy high viscosity oils, transformer oils, and very light low viscosity oils have been used in a Norwegian company in the impregnation, sheathing, and installation of paper insulated cables. The aim of the present study was to determine exposures to oils and other chemicals at these workplaces from 1920 to 1979. Oil mist was sampled on glass fibre or membrane filters and analysed by infrared spectroscopy. Oil vapour concentrations were measured with a direct reading total hydrocarbon analyser with a flame ionisation detector. The results suggested average oil mist levels of 0.5-4 mg/m3 and oil vapour levels within 10-100 mg/m3. Definitive exposure to asbestos occurred in sheathing until the late 1950s, whereas only minor exposure to asbestos took place in installation and impregnation.
一家挪威公司曾使用重质高粘度油、变压器油以及极轻质低粘度油来对纸绝缘电缆进行浸渍、护套制作和安装。本研究的目的是确定1920年至1979年期间这些工作场所中油类和其他化学品的暴露情况。油雾通过玻璃纤维或膜过滤器进行采样,并通过红外光谱法进行分析。油蒸气浓度使用带有火焰离子化检测器的直读式总烃分析仪进行测量。结果表明,油雾平均水平为0.5 - 4毫克/立方米,油蒸气水平在10 - 100毫克/立方米范围内。直到20世纪50年代后期,在护套制作过程中都存在明确的石棉暴露,而在安装和浸渍过程中仅存在少量石棉暴露。
