为了检查弹性半面式呼吸器(EHR)的适合性测试，共有41名候选人被随机分配到7个配备了伊朗工业工作场所常用的有机蒸气(OV)药筒的EHR中。面部尺寸的定性匹配使用Allegro乙酸异戊酯适合性测试试剂盒进行评估。虽然所研究的EHR的合格率很低，但3M、AoSafe(中)和AoSafe(大)的通过率最高，分别为22.0%、14.60%和9.76%。AoSafe(所有尺寸)提供了比3M品牌更高的合身测试通过率(29.30%比22.0%)。与AoSafe三码系统品牌相比，包括Duo和Topax在内的一码适合所有呼吸器的呼吸器通过Fit测试的比例较低(2.40%和4.90%对29.30%)。不同口罩的适合度测试通过率低。不同尺寸和款式的口罩比单一尺寸的口罩有更多的机会让不同的佩戴者通过合身测试。初始和年度适配测试要求应由当地政府制定。此外，制造商在生产过程中也要注意呼吸器的特点和主题特性，以获得对最终用户的满意保护。
To examine the fit testing of elastomeric half face-piece respirators (EHRs), a total of 41 candidates were randomly assigned into seven EHRs equipped with organic vapor (OV) cartridges which were commonly used in the Iranian industrial workplaces. The qualitative fitting into the facial dimensions was assessed using the Allegro Isoamyl Acetate fit test kit. While the studied EHRs showed very low passing fit testing rates, the 3M, AoSafety (Medium), and AoSafety (Large) had the highest passing rates with 22.0%, 14.60%, and 9.76%, respectively. The AoSafety (All sizes) delivered a higher passing fit test rate than the 3M brand (29.30 vs. 22.0%). The one size fits all respirators including the DUO and Climax showed lower proportions of passing fit tests compared with AoSafety three-size system brands (2.40% and 4.90% vs. 29.30%). Low fit test passing rates were determined among different respirators. The respirators with various sizes and styles had more opportunities for different wearers to pass the fit test than single size models. The initial and annual fit testing requirements shall be developed by local government. Also, the manufacturers are required to pay attention to respirator features and subject characteristics during the production to obtain satisfactory protection for the end-users.
