To assess the magnitude of fiber emission from asbestos gloves, 10 pairs were compared in an isolation chamber during simulation of a sterilization procedure; 176 air samples were collected. Means of time weighted average (TWA) concentrations ranged from 0.95 to 11.74 fibers (greater than 5 micrometers)/cm3 of air. Well-worn/clean gloves emitted significantly more fibers than did brand-new gloves, but fiber emission decreased with increased surface soiling. Eighty air samples were collected during simulation of the sterilization procedure in a well-ventilated room. The range of mean TWA concentrations was 0.07-0.99 fiber/cm3 for breathing zone samples and 0.06 to 0.60 fiber/cm3 for area samples. Thirteen samples were collected at actual workplaces; the range of TWA concentrations was 0.07-2.93 fibers/cm3 for breathing zone samples and 0.04-0.74 fiber/cm3 for area samples. Five of seven breathing zone samples from workplaces exceeded the proposed TWA concentration limit of 0.1 asbestos fiber/cm3. Hand contamination also was assessed. Four samples collected after touching the worktable ranged from 9953 to 13 108 fibers (greater than 5 micrometers)/cm2 of hand surface area; seven samples collected immediately after taking off gloves ranged from 741 to 3860 fibers/cm2. Available substitutes for asbestos gloves are discussed, and adoption of these substitutes is recommended strongly.
为评估石棉手套的纤维释放量，在模拟灭菌程序期间，于隔离室内对10副手套进行了比较；共采集了176份空气样本。时间加权平均（TWA）浓度均值在0.95至11.74根纤维（大于5微米）/立方厘米空气之间。磨损严重/干净的手套释放的纤维明显多于全新手套，但纤维释放量会随着表面污染程度的增加而减少。在通风良好的房间模拟灭菌程序期间采集了80份空气样本。呼吸区样本的平均TWA浓度范围为0.07 - 0.99根纤维/立方厘米，区域样本为0.06至0.60根纤维/立方厘米。在实际工作场所采集了13份样本；呼吸区样本的TWA浓度范围为0.07 - 2.93根纤维/立方厘米，区域样本为0.04 - 0.74根纤维/立方厘米。工作场所的7份呼吸区样本中有5份超过了建议的TWA浓度限值0.1根石棉纤维/立方厘米。还对手部污染情况进行了评估。触摸工作台后采集的4份样本，手部表面积的纤维含量在9953至13108根纤维（大于5微米）/平方厘米之间；摘下手套后立即采集的7份样本，纤维含量在741至3860根纤维/平方厘米之间。文中讨论了石棉手套的可用替代品，并强烈建议采用这些替代品。
