在英格兰西北部的10家不同的公司进行了现场定性拟合试验，以确定药品制造行业横截面中泄漏呼吸器的比例。使用3 M FT-10定性适合测试仪对211名半面口罩佩戴者进行了测试，参与者佩戴自己的口罩，并被要求像平时一样佩戴口罩。在所有病例中，在检测前均未进行特异性干预。结果显示，不合格率为69%（211名受试者中，有145名呼吸器泄漏），成功的结果与使用频率（p = 0.71）或佩戴呼吸器的年限（p = 0.59）无关。同样，成功的结果与当前工作中的呼吸器培训（p = 0.38）或以前工作中的培训（p = 0.49）无关。10家公司的泄漏情况并不一致，其中两家公司的失败率为100%，而另一家公司在50名佩戴者中进行了26次成功测试（合格率为52%）。211名参与者中只有35人进行了负压测试。其中，80%的人成功通过了测试，显著高于没有进行压力测试的人的22%的通过率（p < 0.001）。(C) 1999英国职业卫生学会。Elsevier Science Ltd出版，版权所有。
Field qualitative fit tests were conducted at 10 separate companies in the Northwest of England to determine the proportion of leaking respirators in a cross-section of pharmaceutical manufacturing industries. The 3 M FT-10 Qualitative Fit Test Apparatus was used to test a total of 211 half-face particulate respirator wearers, Participants wore their own respirators and were asked to don them as they would normally. In all cases, no specific intervention had occurred prior to testing.Results indicated a failure rate of 69% (of the 211 subjects tested, 145 respirators were leaking), Successful results were not associated with the frequency of use (p = 0.71) or years of experience wearing respirators (p = 0.59). Similarly, successful results were not associated with respirator training in the current job (p = 0.38) or training in previous jobs (p = 0.49). Leakage was not consistent across the 10 companies, with two companies exhibiting a 100% failure rate while another company had 26 successful tests in 50 wearers (52% pass rate). Only 35 of the 211 participants performed a negative pressure test. Of these, 80% successfully passed the test, which was significantly greater than the 22% pass rate among those who had not performed the pressure test (p < 0.001).
