The considerable refinements necessary to enable Class I and II microbiological safety cabinets to operate in a force-ventilated laboratory and to meet appropriate safety criteria have been reported previously. The continued successful operation of such cabinets without a deterioration of operator protection is described. The performance of two Class II units, one meeting and one failing the current British Standard applied to four head KI-discus testing, is compared and discussed. In addition, some further potential difficulties within the environment, which could compromise cabinet containment, are highlighted.
先前已有报道称，为使一级和二级生物安全柜能在强制通风实验室中运行并满足适当的安全标准，需要进行大量改进。本文描述了此类安全柜在不降低对操作人员防护效果的情况下持续成功运行的情况。对两台二级生物安全柜的性能进行了比较和讨论，其中一台符合、另一台不符合适用于四头KI盘测试的现行英国标准。此外，还强调了环境中一些可能损害安全柜防护性能的潜在困难。
